Abstract
A doctrinal and critical analysis of France's Climate and Resilience Law (August 22, 2021) is presented, examining its legal innovations and implications for climate governance. The law, emerging from an unprecedented consultative process, marks a significant evolution in French climate policy and environmental law. It introduces new legal provisions, such as the recognition of ecocide, and aims to align France with ambitious European and international climate objectives. The article situates the law within the broader context of French and EU environmental frameworks, discusses its main features, and critically assesses its challenges, including institutional complexities and implementation gaps.
Introduction
Climate change is one of today's most urgent global challenges. Comprehensive research, including the IPCC Assessment Report, confirms that human activities, especially greenhouse gas emissions, are the main driver of global warming. 1 The 2015 Paris Agreement 2 aims to keep warming below 2 °C, with an aspirational target of 1.5 °C, and to achieve net-zero emissions by mid-century. Despite extensive international negotiations, the real challenge is turning these goals into effective policies that support sustainable development and social equity.
As emphasized by Eskander and Fankhauser, 3 the worldwide reaction to the challenges posed by climate change has fallen short of optimal as in 2020. The Climate Change Laws of the World database 4 documents only 1,800 laws and policies addressing climate change on a global scale, encompassing measures related to both mitigation and adaptation efforts. In 2016, these prevailing climate regulations played a role in an annual reduction of 5.9 GtCO2 in global CO2 emissions, exceeding the total carbon dioxide output of the United States during that specific year. 5
Legal responses represent just one of several tools available to tackle climate change. Although climate laws can play a key role in reducing greenhouse gas emissions, countries such as India have achieved substantial progress without enacting specific climate legislation. 6 Law, therefore, serves as a valuable though not exclusive instrument for advancing climate action.
As a member state, France must reinforce its climate laws to meet broader European objectives. The European Green Deal (EGD), 7 launched in December 2019, offers a roadmap toward climate neutrality. By aligning its legislation with these goals, France can more effectively reduce emissions and contribute to global climate efforts.
France plays a key role in global climate action, having hosted COP21 8 and helped launch the Paris Agreement. Its National Low-Carbon Strategy (SNBC), 9 based on the Energy Transition for Green Growth Law 10 and updated in 2020, outlines a path to a greener economy. Yet, France has struggled to meet its goals, it was the only EU country to miss its 2020 renewable energy targets 11 and now faces a €500 million fine. 12 Recent geopolitical shocks, such as the Ukraine war, have also exposed the risks of relying on fossil fuels, making urgent action even more necessary. 13
In this shifting context, France has adopted a pivotal new legislation: the law n° 2021-1104 of August 22, 2021, known as the Climate and Resilience Law 14 (Loi Climat et Résilience). This law is meant to make big changes to how France deals with environmental issues. However, questions arise about the law's innovative legal mechanisms and their alignment with established environmental doctrines. Adopting a doctrinal analysis methodology, this paper scrutinizes the legal principles, frameworks, and mechanisms introduced by the Climate and Resilience Law. It explores how these elements either comply with or diverge from existing doctrines in environmental law, offering a critical examination of its potential effectiveness and broader implications.
The following sections offer a detailed look at French climate policy. Section 2 reviews EU environmental goals and how France's policies have responded, noting both progress and difficulties. Section 3 explores the role of social movements and recent climate court cases in shaping national policy. Section 4 examines the main features of the new law, its legal basis, and its fit within national and EU frameworks, highlighting the concept of “ecocide.” Section 5 discusses the law's structural challenges, such as overlapping roles and enforcement gaps. Section 6 concludes with key insights and future research directions.
EU & French Legal Frameworks
European Union directives have significantly shaped France's approach to climate policy. The following analysis highlights how EU governance steered national legislation and traces France's evolving climate strategy before the 2021 Climate and Resilience Law.
EU's Influence On National Law
The European Union has played a key role in global climate policy, notably within the UNFCCC. At COP1 (Berlin, 1995), it led efforts for binding emission cuts, helping pave the way for the Kyoto Protocol, 15 which it not only fulfilled but exceeded. 16 EU environmental authority expanded with the Single European Act (SEA),17, 18 the Maastricht 19 and Amsterdam 20 Treaties, and the Lisbon Treaty, 21 which made climate action a shared goal of the Union and its members. The 2019 European Green Deal (EGD) 22 set a roadmap for a sustainable economy across multiple sectors and led to the binding European Climate Law. This law commits the EU to climate neutrality by 2050 and introduced the “Fit for 55” package to cut emissions 55% by 2030. 23 Yet, applying these goals in national laws, especially in complex legal systems like France's, remains challenging. The next section explores how EU climate policy has shaped France's strategies leading up to its 2021 Climate and Resilience Law.
France's Pre-2021 Climate Strategy
Within the EU framework, France's environmental law combines constitutional principles, detailed legislation, and sectoral rules aligned with European standards. The 2005 Environmental Charter, 24 part of the Constitution, enshrines key principles like prevention, precaution, and the polluter-pays rule. The 2000 Environmental Code 25 consolidates laws on water, air, waste, biodiversity, and impact assessments. Enforcement is shared among national and regional authorities, including the Ministry of Ecological Transition, prefects, DREAL, 26 and ARS. 27 Environmental disputes are handled by civil, criminal, and administrative courts, with no dedicated environmental court. However, recent reforms have designated 36 specialized courts to handle complex environmental offenses under the Environmental Code and related legislation, including the Forest and Mining Codes. 28
France's environmental legislation has evolved through key milestones such as the 2009–2010 Grenelle Conferences, 29 leading to the National Low-Carbon Strategy (SNBC), 30 which aimed to cut emissions by half by 2050. Despite ambitious targets, the SNBC struggled with vague, non-binding goals and limited progress in key sectors. Transport remained heavily dependent on fossil fuels, agriculture failed to integrate climate objectives, and industrial efficiency upgrades lagged behind. Poor coordination across sectors led to fragmented action and missed targets. 31 The 2015 Energy Transition Law (LTECV) 32 supported the SNBC and reinforced earlier Grenelle measures. The 2017 Climate Plan, 33 following the Paris Agreement, set 23 objectives across six themes, aiming to cut energy use and CO2 emissions, especially in energy-intensive sectors, with financial support for citizens and SMEs. While the LTECV aimed to reduce nuclear reliance and boost renewables, challenges remained in meeting EU goals. The 2021 Climate and Resilience Law seeks to address these shortcomings by aligning national efforts with EU commitments and creating a clearer, enforceable framework for sustainable development. 34
Societal Mobilization & Law
The enactment of the French Climate and Resilience Law unfolded against the backdrop of a complex sociopolitical landscape marked by the “Yellow Vests” or “Gilets Jaunes” movement, 35 the burgeoning youth climate movement epitomized by figures like Greta Thunberg, and landmark climate litigation cases such as the “Affaire du Siècle”36, 37 (Case of the Century) and the “Affaire de Grande-Synthe.”38, 39 , 40
Originating in late 2018, the Yellow Vests initially protested fuel taxes, evolving into a broader movement highlighting economic disparities and the challenge of balancing environmental goals with economic needs. The movement supported direct citizen participation through the Citizens’ Initiative Referendum and promoted consensus-based politics, while criticizing the government's environmental policies. The subsequent “Great National Debate” 41 garnered over 500,000 participants and led to the promulgation of the law in August 2021, incorporating proposals from the “Citizen's Convention for the Climate” (CCC) initiated after the Yellow Vest protests. President Macron, in response to the protests, recognized the need for social justice in environmental policies, underscoring the importance of a climate law addressing both environmental challenges and social inequalities for a fair transition.
Simultaneously, the youth movement for climate gained momentum globally, inspired by young activists. In France, organizations like “Youth for Climate” mobilized young people to demand more ambitious climate action. 42 The youth climate movement exerted pressure on policymakers to prioritize long-term sustainability and adopt measures aligned with the Paris Agreement. The French government, recognizing the significance of youth voices in the climate debate, sought to engage with these movements.
Another pivotal factor influencing the context of the new law is the surge in climate litigations that garnered significant attention shortly before the proposal of the law. Specifically, the “Affaire du Siècle” and the “Affaire de Grande-Synthe” 43 emerged as pivotal milestones in climate litigation within the French legal system. Legal scholars have extensively examined these litigation cases, delving into the ramifications of climate litigation for environmental governance and the legal complexities involved in tackling intricate climate issues.44, 45
In the “Affaire du Siècle” case initiated by NGOs in 2018, including Association Oxfam, against the government's climate efforts, the Administrative Tribunal of Paris, acting as a court of first instance, heard the argument that the State failed to meet legal obligations. The associations sought State liability, compensation (assessed at 1 euro per association) for moral and ecological damages, and an injunction for the State to align with its Paris Agreement “climate trajectory”. 46 Following the typical structure of liability action, the tribunal assessed fault, damage, and the causal link and prejudice. It found the State's actions inadequate to fulfill legal obligations regarding climate change, akin to the Conseil d’Etat's (State Council) findings. The tribunal held the French State liable for falling short of the greenhouse gas reduction trajectory for 2015–2018 and mandated corrective measures by December 31, 2022, addressing a surplus of 15 megatons of emissions despite the pandemic-driven reduction in 2020. Compensation for moral prejudice was set at 1 euro. However, in its December 2023 ruling, 47 the tribunal acknowledged residual ecological harm of 3 to 5 megatons but concluded that the government's measures demonstrated sufficient effort, rejecting calls for further enforcement. The associations have since appealed to the Conseil d’État, reflecting ongoing scrutiny of state accountability in climate matters. 48
Similarly, the Affaire de Grande-Synthe, a highly publicized case, originated in late 2018 when the city of Grande-Synthe urged the French president and government to address emissions. Citing commitments under the Paris Agreement and domestic law, the plea lay in the city's request for adherence to nationally set emission reduction targets, following both Article L. 100-4 of the Energy Code and Annex I of Regulation (EU) 2018/842, 49 dated May 30, 2018. France's self-imposed targets, established in line with EU regulations and the Energy Code, aimed for a 40 percent reduction (from 1990 levels) within the national territory by 2030. The Conseil d’État, responding to the city's vulnerability to climate change, granted the request and allowed intervention by other parties. 50 The court's decisions in November 2020 and July 2021 compelled the government to justify its refusal and implement “any useful measure” to align with emission reduction paths. In May 2023,51, 52 the court acknowledged partial compliance but refrained from imposing sanctions, emphasizing a cooperative rather than punitive approach to enforcing climate goals. The case underscored the court's proactive role in monitoring compliance and setting precedents for anticipatory oversight of state climate policies.
The Grande-Synthe's case demonstrates how a climate lawsuit can shape a state's climate policy, 53 with the Conseil d'État taking a proactive role in ensuring compliance and setting legal precedents for anticipatory oversight and periodic reviews.
The French Climate and Resilience Law, enacted amid these societal and legal dynamics, aimed to reconcile environmental imperatives with social justice concerns. This legislation, influenced by the Yellow Vest movements and youth climate activism, was designed to provide an inclusive approach to climate policy. It has since gained academic attention for its framework, which integrates environmental and social justice principles. The law's passage, coupled with these key legal decisions, has opened avenues for research into the role of litigation in shaping national climate policy. The inception of this new law, in the context of recent court rulings, will pave the way for extensive research on the challenges and opportunities in formulating legislation that encompasses both environmental 54 and social dimensions.55, 56
Architecture of the Law
The Climate and Resilience Law was introduced by the French Minister for Ecological Transition, Barbara Pompili, as the “most important environmental law of the five-year term,” affecting areas such as transport, housing, and consumer habits. 57 It adds environmental education to the Education Code 58 and includes measures like making homes more energy-efficient. The law supports France's goal of cutting greenhouse gas emissions by 40% by 2030, as set by Article L. 100-4 of the Energy Code. 59
Climate Governance Overhaul
The French Strategy for Energy and Climate (Stratégie française pour l’énergie et le climat, SFEC) 60 sets out France's plan to reach carbon neutrality by 2050, in line with EU targets and the Paris Agreement. However, the SFEC faces key challenges, such as cutting greenhouse gas emissions, moving away from fossil fuels, expanding renewable energy, and ensuring energy security. 61 The 2021 Climate and Resilience Law aims to put the SFEC's goals into action by making carbon neutrality a legal objective and improving rules for renewable energy and energy efficiency. In its 2021 report, the Haut Conseil pour le Climat (HCC) recognized that the law follows the SFEC's direction but warned that “current efforts are insufficient to ensure that the 2030 objectives are met.” 62 This shows that stronger action and better enforcement are still needed. The law is a step forward, but its success depends on clear, binding measures and stronger institutions to ensure follow-through and accountability.
The Climate and Resilience Law includes 8 titles, 18 chapters, and 305 articles. 63 It incorporates 146 proposals from the CCC, covering major themes like consumption, production, work, travel, housing, and food. It also introduces new environmental crimes to strengthen legal protection. Article 1 of the law, 64 confirms France's commitment to the EU goal of cutting greenhouse gas emissions by at least 55% by 2030.
The law sets targets such as cutting fossil fuel use by 40% by 2030 (up from 30% under the 2015 law), ending coal power on the mainland by 2022 with worker support, and delaying the reduction of nuclear power's share to 50% by 2035 to avoid building new gas plants and increasing emissions.
To achieve these ambitious targets, strong independent oversight is essential. The High Council for the Climate (HCC), 65 created by the decree of 14 May 2019 66 acts as an expert body monitoring France's progress on climate targets, including those in the Climate and Resilience Law. Its critical reports have helped shape the law, encouraging better alignment with national and international commitments. Although it lacks rule-making or enforcement powers, the HCC influences policy through annual reports offering forward-looking advice and evaluations of past actions. 67 These reports are submitted to the executive and Parliament, which must respond within six months, integrating the HCC's oversight into the policy process. However, its autonomy is debated, it operates under the Prime Minister's authority and depends on government support. However, its autonomy is debated, it operates under the Prime Minister's authority and depends on government support. Its limited scope, with no direct role in legislative debates or citizen engagement, reflects a technocratic model that has been criticized for lacking democratic input.
Sectoral Shifts And Key Measures
The Climate and Resilience Law addresses multiple fronts, including the transportation sector, with goals to phase out petrol and diesel car sales by 2040 and reduce oil dependence through incentives like vehicle conversion bonuses, ecological bonuses, and support for carpooling and cycling. Additionally, it emphasizes energy policy by prohibiting new hydrocarbon exploration or exploitation projects 68 and prioritizing the transition away from oil-fired boilers, supported by conversion bonuses. Lastly, it addresses energy poverty 69 and aims to assist households facing rising energy costs by expanding the reach of energy vouchers to 5.8 million beneficiaries. 70
Overall, the Climate and Resilience Law integrates France's climate goals with practical measures across sectors, underlining the nation's commitment to addressing climate change and fostering sustainability. The law provides in particular in terms of consumption that an environmental label (“eco-score”) will be created for products and services 71 as well as a ban on advertising in favor of fossil fuels. 72 Production and work will also be emphasized 73 as well as the alignment of the national research strategy with the SNBC, the inclusion of environmental considerations in public procurement, the modification of several provisions of the mining code, and the breakdown of the multiannual energy program into regional objectives for the development of renewable energies. Transport is also an important part of this new bill. To tackle climate change, several measures are planned. Low-emission zones (LEZ) will be established in urban areas with more than 150,000 inhabitants, where the oldest cars will be banned. Conversion bonuses will be extended to include electric bicycles. Domestic flights will be prohibited when a train alternative of less than two and a half hours is available. The sale of the most polluting new cars, those emitting more than 95 grams of carbon per kilometer, will end by 2030. Additionally, truck drivers will receive training in eco-driving techniques. 74
Regarding housing and soil artificialization, the measures include the gradual elimination of “thermal sieves,” the introduction of financial aid for renovation work, halving the rate of concrete construction by 2030, banning the construction of new shopping centers that lead to soil artificialization, and ensuring that 30% of the national territory is covered by protected areas.
Criminal Law: Ecocide And Beyond
Under the new Climate and Resilience Law, criminal sanctions will be toughened in the event of damage to the environment, particularly when it is intentional and has serious and lasting effects. Let us stress that between 2015 and 2019, public prosecutors dealt with 86,200 cases involving one or more individuals related to disputes over pollution or environmental damage. Among the 103,500 individuals involved in these cases, 28% were found not prosecutable, and 92% of prosecutable individuals received a legal response. 75 The new legal framework strengthens environmental protection by adding new offenses. 76 Specifically, these include charges related to jeopardizing the environment, engaging in environmental pollution, and addressing the most severe cases through the establishment of an ecocide offense. 77
Article 280 78 of the 2021 Climate and Resilience Law added Articles L.231-1 to L.231-3 79 to the French Environmental Code to punish serious environmental harm. Article L.231-1 addresses intentional pollution causing long-term damage to health or ecosystems; Article L.231-2 concerns illegal waste dumping and poor waste management. Article L.231-3 defines ecocide as the intentional commission of these acts with serious and lasting harm (over seven years). Penalties were raised to ten years in prison and fines up to €4.5 million. Under Article L.173-13, these offenses are treated similarly for repeat violations, reinforcing France's legal stance on ecological harm. 80
In examining the definitions and legal treatment of ecocide within the framework of both French law and the new EU Directive 2024/1203, 81 it becomes evident that while progress has been made in addressing environmental offenses, neither has fully embraced ecocide as a distinct crime. The Climate and Resilience Law, designates ecocide as an intentional offense, primarily targeting acts of severe pollution that result in significant and lasting harm to health, flora, fauna, or the quality of air, soil, or water. This definition is narrow in scope, emphasizing intentionality and focusing on environmental harm with direct and observable consequences.
EU Directive 2024/1203 expands environmental criminal law by requiring Member States to include 20 specific offenses in their laws. 82 However, it does not mandate the recognition of ecocide as a separate crime. Article 3(3) introduces “qualified offenses” for actions like destroying major ecosystems or causing serious, lasting damage to air, soil, or water. Recital 21 notes these may resemble ecocide, already recognized in some countries or debated internationally, but the directive avoids formally defining it.
The directive also increases penalties, with minimum prison terms and fines for individuals and companies, going further than French law, especially on negligence and environmental repair. While French law sees ecocide as an intentional act, the directive includes harmful behavior from negligence under its qualified offenses.
Both French law and the EU Directive 2024/1203 address serious environmental harm, but their reluctance to define ecocide shows the challenge of aligning domestic and EU law with global demands for recognition. This cautious stance reflects a balance between environmental goals and political considerations.
Under Article 296 of the French legislation, the government must submit a report to parliament within two years on steps taken to promote ecocide's recognition under international criminal law. The High Council for the Climate (HCC) is tasked with annual evaluations, and the Court of Auditors will review local climate actions every three years, focusing on greenhouse gas reductions and climate adaptation.
Legal Synergy : National & EU
Understanding how the Climate and Resilience Law interacts with existing legal frameworks is important because France's climate rules must match EU directives and global commitments. The law's success depends on how well it strengthens, fills gaps, or avoids conflicts with existing laws like the LTECV 83 and the SNBC. 84 This also shows whether the law brings real change or just repackages older goals.
Rather than standing alone, the law builds on France's earlier environmental efforts. It updates the LTECV by setting clearer and stronger targets, such as cutting fossil fuel use by 40% by 2030, more than the 30% goal from 2015. It also pushes the deadline for lowering nuclear energy to 50% from 2025 to 2035, helping avoid more gas-powered plants.
The law supports revising the SNBC every five years to keep it in line with changing emission trends. 85 It streamlines rules for renewable energy, cracks down on fraud in energy-saving programs, and promotes faster project approvals.
The law also aligns with the EU Green Deal (EGD). It boosts building energy efficiency under Title V, introduces landlord renovation duties, supports eco-friendly farming, and promotes circular economy practices. 86 Article 26 updates the Environmental Code by adding a National Circular Economy Council under the Ministry of the Environment, in line with the EU's 2020 Circular Economy Plan. 87
Finally, the law reinforces the EU's Environmental Impact Assessment Directive by requiring strict environmental reviews at all stages of major projects, ensuring full compliance with EU environmental standards.
Environmental Principles
The Climate and Resilience Law is firmly rooted in foundational principles of jurisprudence that have long been integral to both French and EU legal traditions. In addition to general international law, the normative framework, which includes, the Stockholm 88 and Rio declarations 89 ; Agenda 21 90 ; the Johannesburg Plan of Implementation 91 ; the Group of Eight (G8) Gleneagles 2005 Plan of Action, 92 and the Sustainable Energy for All initiative 93 serves as a crucial reference for examining the lex specialis principles of international climate law. As these principles tend to become a legal concept, it must produce effects within relationships originating from environmental damages. It should be consecrated as a responsibility principle to ensure the reparation of such damages, forming the basis for an adequate regime for ecological damage compensation. Justice principles related to the distribution of burdens and rights regarding climate change primarily revolve around the criterion of greenhouse gas emissions. While this “holistic” 94 approach aligns with the causal link between emissions and climate change, it encounters significant ethical challenges, as emissions may not always be the central ethical consideration in all areas of climate action. Other factors may gain greater significance, requiring a nuanced approach in defining equitable rights and responsibilities across different domains of climate action. 95
The Precautionary Principle, 96 , 97 deeply embedded in environmental jurisprudence, advocates for proactive action in the face of environmental threats, especially when dealing with uncertain or potentially irreversible impacts. 98 The integration of the Charter of Environment in 2005 into the constitution of the Fifth French Republic, 99 only one year after having been adopted, aimed to go beyond the philosophical dimensions of the declared rights and beyond the educational aspect. It sought to elevate principles, especially key ones like the prevention principle and the precautionary principle, from mere legal rights, which are protected by statutes, to the status of constitutional rights. 100 The environmental precautionary principle involves three imperatives: 101 minimizing risks and avoiding emissions even without immediate effects, defining environmental quality objectives, and establishing an ecologically guided approach to environmental management.
As Kerbrat and Maljean-Dubois note, 102 international courts have gradually shaped the precautionary principle through legal dialogue, clarifying its authority and content despite its resistance to clear systematization. Maljean-Dubois and Peel 103 add that in climate law, even with scientific progress, many actions remain precautionary due to ongoing uncertainties. The line between precaution and prevention is blurred, requiring adaptive legal tools.
The Climate and Resilience Law reflects this need, especially regarding future emissions and biodiversity risks. Article 1 of the law (2021-1104) embeds the prevention principle by stressing early action to avoid harm, aligning with Paris Agreement and EU climate goals. It commits to emission cuts and integrates updated EU emissions rules.
This principle also appears in Article L.541-9-11 (Title II, Chapter I), which requires environmental impact labeling for products. This informs consumers about climate, biodiversity, and resource effects across a product's life cycle, an example of precaution through transparency.
Finally, Article 5 of the law promotes environmental education to equip students with knowledge and skills to face ecological and social challenges. Oversight mechanisms ensure this is consistently applied, reinforcing the law's alignment with prevention and long-term climate preparedness.
The “polluter-pays” principle,104, 105 introduced by the OECD 106 in 1972, links the cost of goods to the use or impact on environmental resources, reflecting their scarcity. However, its meaning and functions remain unclear, evolving differently in international, EU, and national law. 107 It involves internalization, incentives, and redistribution, making its legal status complex. As it becomes a legal concept, it must ensure responsibility for environmental harm and support a system for ecological damage compensation. In France, Article 4 of the Environmental Charter highlights the duty to repair environmental damage, while the Environmental Code affirms the principle's role in prevention and repair.
The 2021 Climate and Resilience Law strengthens this principle through tougher environmental criminal penalties. Article 279 of Law No. 2021-1104 creates an offense for endangering the environment, while Article 280 addresses environmental damage, including pollution of physical and biological environments. These provisions increase accountability and reinforce the “polluter-pays” logic. Haut du formulaire

The French Climate and Resilience Law does not adopt a rights-based or human-centric approach in its legal architecture. While it builds on foundational environmental principles such as precaution, prevention, and the polluter-pays principle, it falls short of recognizing environmental protection as a justiciable human right. 108 The law does not incorporate explicit references to the right to a healthy environment, nor does it embed broader international human rights standards, such as equity, participation, or intergenerational justice. As highlighted by the French National Human Rights Commission (CNCDH) in its 2021 opinion, the law lacks a normative rights framework and fails to provide sufficient protection for vulnerable populations most affected by climate change. 109 This gap is increasingly evident in light of evolving international norms, including UN General Assembly Resolution 76/300 (2022), which affirms the right to a clean, healthy, and sustainable environment, 110 and recent jurisprudence from the European Court of Human Rights linking environmental degradation to violations of Article 8 ECHR. 111 Despite high-profile litigation such as the Affaire du Siècle, which challenged the state's insufficient climate action, these efforts have not led to the recognition of enforceable individual rights. Scholars and civil society advocates therefore continue to call for a transition from a primarily procedural regulatory model to one that integrates substantive rights-based climate governance. 112
Limits and Critiques of the Law
Legal And Constitutional Limits
A constitutional challenge was filed against the Climate and Resilience Law, arguing it perpetuated state inaction on greenhouse gas reductions and failed to uphold citizens’ right to a healthy environment under Article 1 of the Environmental Charter. 113 Inspired by Germany's Federal Constitutional Court ruling in March 2021, which linked climate change to fundamental rights and led to stronger emissions targets, 114 French deputies asked the Constitutional Council to urge legislative reform. This underscores the substantial impact of judicial decisions on climate policy, showcasing the pivotal role of courts in advancing climate action and ensuring government accountability. 115 Haut du formulaire.

After assessing the new law 2021/1104, the Constitutional Council ruled that this argument could only be effectively raised before it, following the procedures outlined in Article 61 of the French Constitution 116 or the priority preliminary ruling on constitutionality, and specifically against contested provisions. Additionally, the Council emphasized that it lacked the authority to issue general injunctions to the legislature. In this case, since the challengers provided only a general critique of the legislator's ambitions and the overall inadequacy of the law, without contesting any specific provisions for annulment, the Constitutional Council concluded that their argument could not be sustained.
After reviewing Law 2021/1104, the Constitutional Council ruled that only specific provisions can be challenged under Article 61 of the French Constitution 117 or through a priority constitutional question. It also confirmed that it cannot issue general orders to the legislature. Since the challengers raised broad concerns without targeting any specific article for annulment, their claim was rejected. They also challenged Article 215, which set new rules for authorizing commercial projects involving land artificialization. Critics argued it unfairly excluded online warehouses, creating unequal treatment compared to physical stores. However, the Council found no violation, as warehouses are already excluded under Article L.752-1 of the Commercial Code. 118 The Council also struck down parts of Articles 81 and 173 119 for violating Article 38 of the Constitution, 120 as they improperly gave the government power to revise the Mining and Building Codes. Other provisions were annulled as “legislative riders” for breaching Article 45. These decisions do not stop further review of their content for constitutional compliance.
In a February 2021 opinion, the High Council for the Climate criticized the law's lack of ambition and weak emission reduction measures. 121 Although France has pledged carbon neutrality by 2050 under the 2019 energy and climate law, the Council warned that the new law's delayed deadlines (2024–2030) and narrow scope fall short of the pace needed to meet national carbon budgets.
The High Council for the Climate (HCC) acknowledged that the impact study for the Climate and Resilience Law marked progress by referring to the SNBC. However, it criticized the study's lack of methodological clarity and summary, which makes it difficult to evaluate the law's overall impact on France's greenhouse gas emissions. The HCC also found the use of the term “resilience” misleading, since only 2 out of the law's 69 articles address climate adaptation.
Enforcement Gaps
The Climate and Resilience Law is more than a set of ecological rules; it is a broad legal framework aimed at transforming key sectors like education, housing, and transport. While the government presents it as a policy priority, questions remain about its practical enforcement and monitoring, an issue raised in legal scholarship on environmental law. 122 Though the law sets ambitious targets, such as cutting greenhouse gas emissions by 40% by 2030, it lacks clarity on how these goals will become concrete, enforceable actions. The law's effectiveness depends on clear measures and strong enforcement mechanisms. 123
Therefore, it's crucial to scrutinize the law's provisions to assess their adequacy for achieving the stipulated objectives. As mentioned before, the law encompasses 305 articles, indicating the breadth of issues it aims to address. This comprehensive approach is its strength but also its potential downfall. Legal complexity often leads to implementation challenges, as noted by Lazarus in his seminal work on the pitfalls of environmental law. 124 The law incorporates proposals issued from the CCC. While this inclusion is commendable for democratizing law-making, scholars like Dryzek and Niemeyer 125 have cautioned that deliberative processes may also introduce a variety of conflicting objectives, leading to potential dilution of focus.
Furthermore, the law establishes multiple new environmental crimes and gives the High Climate Council a role in assessing its implementation. 126 These aspects enhance the law's potential for enforceability and ongoing adaptability, key criteria in the effectiveness of environmental legislation as argued by Fisher. 127 As per Julien Bétaille, 128 effectiveness might be characterized as"the quality of a norm whose effects achieve its objective.”
Although, the Climate and Resilience Law in France was designed to provide a robust framework for the country's transition to a low-carbon economy, its implementation remains incomplete three years after its promulgation, with an overall applicability rate of 70%. This leaves 30% of provisions either delayed or insufficiently enacted, as reported in May 2024 by a French Senate report. 129 Of the 141 measures anticipated, 42 remain unimplemented. The report also highlighted that the emission reductions required to meet the 2030 target have not progressed at the expected pace. While the law set an ambitious goal to reduce emissions by 40% by 2030, emissions as of 2025 have only decreased by 22% compared to 1990 levels. Key provisions, such as the ban on domestic flights where train alternatives exist, have been delayed, undermining the law's credibility and effectiveness. The 30% of unimplemented measures further highlight the law's limitations, such as delays in renovation programs and the continued reliance on fossil fuel subsidies, which remain at €8 billion annually, an amount in direct contradiction to the law's objectives.
From a legal perspective, the law's implementation reveals two primary issues: lack of enforcement and financial constraints. While the law contains enforcement provisions, they have not been consistently applied, particularly in terms of meeting deadlines for specific actions, such as the gradual phase-out of fossil fuels or the completion of renovation projects in residential buildings. The law, though comprehensive in scope, has struggled to provide sufficient financial support to make compliance feasible for all stakeholders, especially low-income households and small businesses, which face considerable economic barriers to implementing the required changes. 130 The administrative complexity involved in navigating the law's provisions has also delayed its full realization, leading to public frustration and doubts regarding the law's long-term viability.
Environmental law in France has been less effective due to slow court procedures and penalties that are not strong enough. Environmental cases often experience significant delays, much longer than delays in other areas of law, which compromises the timely enforcement of legal remedies. Additionally, penalties for environmental violations, often limited to fines, are widely regarded as insufficient to deter offenses or compel compliance.
A key example of the gaps in the application of the law is the introduction of ecocide in the 2021 Climate and Resilience Law. Despite the severity of potential penalties, including up to 10 years in prison and substantial fines, no cases have yet resulted in convictions. This difficulty in applying the law illustrates the challenges inherent in environmental protection, particularly when it comes to prosecuting long-term damage. Furthermore, the regional environmental courts intended to address such issues remain underutilized, with most environmental cases being handled by non-specialized courts.
Ultimately, the success of these reforms will depend on France's ability to harmonize criminal, civil, and administrative procedures in a way that allows for more efficient enforcement. While legal tools are available, the real challenge lies in ensuring they are used effectively to address the pressing environmental crisis. The French legal system must adapt and integrate these evolving frameworks to ensure the robust protection of the environment for future generations.
Governance And Administrative Issues
The Climate and Resilience Law exhibits laudable ambition by weaving together multiple thematic areas such as consumption, production, travel, housing, and food. However, the layered nature of the text raises questions of governance, enforceability, and interpretative coherence. The interdisciplinary structure of the law requires coordinated governance. This has raised concerns in jurisprudential literature about administrative complexities involved in cross-cutting legal frameworks as raised by Hudson and Rosenbloom. 131
Multi-level governance demands multi-agency collaboration, which in turn requires a robust administrative structure to reconcile potentially conflicting interests. Scholars like Ebbesson and Hey 132 have argued that environmental governance often struggles with integrating multiple jurisdictions and legal paradigms, thus posing a challenge to effective implementation.
Ronald Dworkin, in his famous work “Law's Empire,” noted the importance of interpretive coherence in a legal framework. 133 The multiplicity of themes in this law raises concerns about achieving a coherent interpretation. For instance, while the law mandates an ambitious eco-score labeling system for products, it also emphasizes modifications to the mining code. These represent disparate sectors with different stakeholders, thus complicating a unifying legal interpretation. Legal interpretive challenges can sometimes dilute the intended impact of a law, as observed in the case studies presented by Burrows. 134
Enforceability stands as one of the most critical aspects of any legal framework. The Climate and Resilience Law brings in a variety of new environmental crimes such as ecocide. While the introduction of criminal sanctions is a robust step, Nollkaemper questions the practicality of enforcing such complex legal standards. 135 The role of the High Climate Council in assessing the law's implementation yearly adds an additional layer to the oversight mechanism, which could either strengthen the law's accountability or add bureaucratic delays.
The law does not operate in isolation but interacts with international climate commitments, including EU mandates. 136 France's commitment to EU objectives, particularly to reduce GHG emissions by 55% by 2030, adds another layer of normative obligations. How does this national law align with France's commitments under the Paris Agreement, and what happens in case of conflicting obligations? Bodansky highlighted that domestic laws sometimes face challenges when integrated into global climate governance frameworks. 137
Democratic & Participatory Gaps
Debate over the effectiveness and ambition of the French Climate and Resilience Law has intensified among legal scholars, who have scrutinized its capacity to deliver on both environmental and democratic promises.While the law has been lauded for its innovative elements and its alignment with European climate ambitions, it has also attracted significant scholarly criticism. Despite its broad scope and initial promise, leading scholars consistently argue that the Climate and Resilience Law does not meet expectations in terms of legal ambition or democratic depth. Danièle Cournil and Stéphane Lavorel highlight the law's weak justiciability and the prevalence of non-binding provisions, which undermine its enforceability and its capacity to drive meaningful climate action. 138 They further criticize the dilution of citizen proposals from the Convention Citoyenne Pour le Climat during the legislative process, resulting in a loss of transformative potential and illustrating how participatory innovations are often neutralized by parliamentary and executive control.
Similarly, Regourd, Rimbault, and Verpeaux emphasize the law's technocratic complexity, which limits accessibility and weakens public ownership, and they note the lack of binding mechanisms to translate citizen input into substantive legislative outcomes. 139 These scholars argue that the law reflects a form of “guided democracy”, 140 where participatory processes exist but substantive decision-making remains tightly controlled by institutional actors, a concept well established in political science literature. The law's approach to social justice is also seen as inadequate, offering only minimal protections for vulnerable groups and failing to establish a robust redistributive framework. Institutional fragmentation and overlapping governance structures further complicate effective implementation. Overall, these critiques converge on the view that the law's procedural focus, weak democratic mechanisms, and insufficiently binding tools limit both its environmental effectiveness and its legitimacy as a vehicle for participatory democracy in France. 141
In sum, the Climate and Resilience Law is an important milestone in France's environmental journey, but it should be seen as a foundation rather than a culmination. Its success will depend on whether policymakers and society can move beyond procedural compliance to embrace a more integrated, equitable, and enforceable approach to climate governance, one that delivers not only on ambition, but also on tangible, just, and lasting results.
Pathways for Legal and Institutional Reform
Despite its breadth and ambition, the Climate and Resilience Law remains normatively incomplete and institutionally fragile. As the High Council for the Climate and multiple legal scholars have noted, the law's limited binding force, excessive reliance on regulatory deferrals, and fragmented implementation mechanisms hinder its effectiveness. The absence of systematic judicial review of climate inaction, unlike the German Federal Constitutional Court's landmark Neubauer ruling 142 (BVerfG, 1 BvR 2656/18, March 2021), reflects a critical gap in French climate litigation architecture.
From a doctrinal standpoint, the law suffers from under-specification of justiciable obligations and lacks robust mechanisms for democratic accountability. Scholars such as Bétaille 143 and Cournil 144 emphasize that without enforceable rights, climate legislation risks remaining symbolic. To overcome this, France should consider embedding a ‘climate rights’ framework that guarantees access to justice, public participation, and measurable outcomes, aligned with Article 6 of the Paris Agreement 145 and the Aarhus Convention. 146
Institutionally, France must streamline the overlapping competencies of environmental agencies, courts, and ministries, moving towards a more integrated climate governance model as recommended by Regourd and Verpeaux. 147 This could include the creation of a Climate Implementation Authority with investigative and sanctioning powers, modeled after UK's Environment Agency (EA) 148 or Netherlands's Climate Policy Council. 149
Additionally, procedural innovations like the Convention Citoyenne pour le Climat should evolve into permanent co-decision mechanisms with legally binding outputs, rather than remaining purely consultative. Drawing on deliberative democracy literature,150, 151 these citizen panels must be paired with institutional guarantees to prevent dilution during parliamentary or executive revision.
Finally, the law's carbon neutrality objective will remain unattainable unless backed by statutorily ringfenced climate finance, ending regressive subsidies and ensuring equal access to renovation and decarbonization tools for low-income households. This requires shifting from “programmatic ambition” to legal enforceability, a transformation that European legal doctrine increasingly considers vital for climate law legitimacy. To serve as a durable legal instrument in France's ecological transition, the law must evolve through institutional rationalization, rights-based enhancement, and procedural democratization.
Conclusion and Outlook
The 2021 Climate and Resilience Law marks a significant step in France's environmental legal system, reflecting the interplay of social movements, political responses, and legal developments. It attempts to translate the long-term ambitions of the French Strategy for Energy and Climate (SFEC) into binding rules, setting carbon neutrality by 2050 as a statutory goal. The law's enactment was shaped by the influence of the Yellow Vest movement, which highlighted the need for social justice in climate policy, and by youth climate activism, which underscored the urgency of ambitious action. Landmark climate litigation, such as the Affaire du Siècle and the Affaire de Grande-Synthe, has further contributed to the evolving legal discourse on climate responsibilities.
Despite these advances, the law falls short of fully aligning with France's climate objectives. The architectural complexity of the Climate and Resilience Law poses multiple challenges. While its comprehensive nature is its strength, it could also be its Achilles heel, raising critical questions of governance, interpretative coherence, and enforceability. Complex regulations, norms that are difficult to enforce, and fragmented institutions have hindered the law's practical effectiveness. The disparities between the recommendations of the Citizens’ Climate Convention (CCC) and the final legislative text illustrate the compromises inherent in the legislative process.
Nevertheless, this legislation offers valuable lessons for future climate policy. First, it demonstrates both the potential and limitations of embedding climate objectives across different areas of law. Second, it introduces innovative participatory tools, such as the Citizens’ Climate Convention, which provide models for democratizing lawmaking, even if their outputs are not always binding. Third, it highlights the necessity for legal clarity, enforceability, and inter-agency coordination to prevent administrative dilution of climate action. The creation of new environmental offenses, including ecocide, reflects an important legal shift, though courts and prosecutors have been cautious in applying these new provisions. Notably, the nuanced categorization of ecocide as an “offense” rather than a “crime” underscores the delicate balance between societal demands and legal practicalities.
The law's alignment with broader European policies, such as the Paris Agreement and the European Green Deal, reinforces the importance of harmonizing national legislation with international commitments. The forthcoming 2024 EU Directive presents an opportunity for France to strengthen its environmental protection mechanisms and further harmonize its laws with European standards. However, the success of these reforms will depend on overcoming the practical and interpretative challenges posed by the law's complexity. Effective enforcement, coordinated governance, sufficient funding, and transparent compliance metrics will be essential for realizing the law's ambitions.
Looking ahead, three promising directions for research and policy emerge. First, comparative studies should explore how different countries bridge the gap between declarative climate goals and enforceable law. Second, the effectiveness of participatory mechanisms in producing binding environmental outcomes warrants further investigation, particularly in systems that blend technocratic and democratic approaches. Third, there is a need to examine how climate rights, both procedural and substantive, can be embedded in national legal systems in ways that are actionable in courts and resilient to political shifts.
In sum, while the Climate and Resilience Law is a landmark in French environmental legislation and a testament to the country's commitment to addressing climate change, its ultimate success will depend on addressing the challenges of complexity, enforcement, and institutional coherence. If these obstacles can be overcome, the law has the potential to serve as a model for ambitious and effective climate governance worldwide.
