An Engineering Approach to Sustainable Decision Making

Abstract

Climate change is often tackled via a two-pronged approach of behaviour change and technological advancement. Policy studies and social sciences generally take ownership of influencing behaviours, while natural sciences and engineering tackle generating newer, more efficient technologies. Fusion of these methodologies is severely lacking. Engineers are uniquely situated to contribute to positive environmental action in both technological and behavioural realms. This article explores the psychological mindset of engineers as they make decisions to dissect factors that undermine sustainable behaviour. The Theory of Planned Behaviour, Multi-Criteria Decision Analysis and the Health Belief Model are applied to engineering decision making to develop a methodology for engineers to modify their behaviour to consistently make more sustainable choices, and in turn, assist others by making actions towards sustainability more convenient.
