Best Practices and Insights to Expand Clean Energy Access and Adoption

This report was commissioned by the European Commission to serve as a technical repository of analysis and evidence-based practices in support of the Campaign on Sustainable Lifestyles, Fairness and Access to Clean Energy Technologies. The analysis presented draws on discussions and research shared during the Widening Participation in Clean Energy workshop held in Brussels, contributions presented at the official all-member meetings of the Campaign on Sustainable Lifestyles, and the IEA’s analytical work in areas such as people-centred clean energy transitions, affordability, energy efficiency and clean energy access.

This work is organised into three chapters, each corresponding to one of the three components of the Declaration on Promoting Sustainable Lifestyles, Fairness and Access to Clean Energy Technologies. The analysis and case studies included demonstrate how the principles outlined in the Declaration can be implemented in practice across different country contexts.

The recent energy crisis and rising energy costs have underscored the importance of affordability, fairness and access to clean energy technologies, particularly for vulnerable households. At the same time, evidence points to the importance of both individual actions as well as broader policy frameworks, enabling infrastructure, and investment that support long-term behavioural change.

This report examines how policies, public engagement and sectoral transformation can create conditions for sustainable lifestyles that follow low-emissions practices and are resilient and inclusive. It draws on international evidence, including workshop discussions, IEA analysis and a wide range of global case studies, to identify key impacts and lessons learned from evidence and practice. It highlights how behaviour change is most effective when supported by coherent policy frameworks, targeted measures addressing affordability and structural changes across sectors such as buildings, transport and appliances. By identifying good practices and practical insights, the report provides guidance to support policymakers design inclusive strategies that enable sustainable lifestyles and ensure the benefits of the energy transition are shared by all.
