Driving environmental sustainability in the EU specialized milk farms: Strategic CO2 emission reductions for a greener future

Abstract

This study assesses the environmental efficiences of specialized milk farms across the European Union (EU) countries, with a focus on CO2 emissions reduction. Using Tone's model under the assumption of generalized returns to scale, the analysis reveals an average environmental efficiency score of 0.599. Countries like Malta, Ireland, Italy, and the Netherlands have achieved full environmental efficiency, exemplifying optimal environmental performance. In contrast, countries such as Slovakia and Estonia demonstrate lower efficiency, suggesting significant opportunities for emission reductions. Czechia, Bulgaria, and Estonia show environmental efficiency levels ranging from 0.24 to 0.30. In contrast, Finland, Portugal, Romania, Lithuania, Croatia, Hungary, Latvia, and Slovenia have achieved efficiency levels that fall between the average of 0.30 and a value of 0.599. The study highlights that higher populated and higher-income countries tend to exhibit higher environmental efficiency. The findings suggest that to improve environmental efficiency, milk production should be concentrated in larger farms, with an emphasis on sustainable agricultural practices, advanced technologies, and efficient resource management. Furthermore, the study recommends targeted policies and strategies to enhance environmental efficiency, particularly in countries with lower population densities and incomes. These strategies include transitioning to pasture-grazing systems, improving nitrogen use efficiency, enhancing animal welfare, and investing in advanced farming technologies. The study underscores the importance of integrating environmental considerations into broader agricultural policies to achieve sustainability in the specialized milk farms of the EU.
