The analysis presented draws on discussions and research sharedduring the Widening Participation in Clean Energy workshop held in Brussels,contributions presented at the official all-member meetings of the Campaign onSustainable Lifestyles, and the IEA’s analytical work in areas such as people-centred clean energy transitions, affordability, energy efficiency and clean energyaccess. This work is organised into three chapters, each corresponding to one of the threecomponents of the Declaration on Promoting Sustainable Lifestyles, Fairness andAccess to Clean Energy Technologies. The analysis and case studies includeddemonstrate how the principles outlined in the Declaration can be implemented inpractice across different country contexts. The recent energy crisis and rising energy costs have underscored the importanceof affordability, fairness and access to clean energy technologies, particularly forvulnerable households. At the same time, evidence points to the importance ofbothindividual actions as well as broader policy frameworks,enablinginfrastructure, and investment that support long-term behavioural change. Thisreport examines how policies,public engagement and sectoraltransformation can create conditions for sustainable lifestyles that follow low-emissions practices and are resilient and inclusive. It draws on internationalevidence, including workshop discussions, IEA analysis and a wide range of globalcase studies, to identify key impacts and lessons learned from evidence andpractice. It highlights how behaviour change is most effective when supported bycoherentpolicy frameworks, targeted measures addressing affordability andstructural changes across sectors such as buildings, transport and appliances. Byidentifying good practices and practical insights, the report provides guidance tosupport policymakers design inclusive strategies that enable sustainable lifestylesand ensure the benefits of the energy transition are shared by all.

The report was directed by Jane Cohen, and thelead author was Matthieu Prin and Alberto Maggi, with additional input from MilenaMegre and Elspeth Hathaway. Important input was received from the co-leads of the Clean Energy Ministerial(CEM) Campaign on Sustainable Lifestyles, Fairness and Access to Clean EnergyTechnologies. This included the European Commission (Endre Gyorgy, FabioDomanico, Frank Siebern, and Anais-Clarissa Gradinger), the Norwegian MinistryofEnergy(Olav Bauer-Nilsen),the Indian Bureau of Energy Efficiency(DeepshikhaWadhwa),the Chinese Wind Energy Association(Wang Mu),ZhangjiakouEnergy Association(ZEA),Bureau of Energy Efficiency(ArijitSengupta) and the CEM Secretariat (Badariah Yosiyana and Jean-FrançoisGagné). This report benefited greatly from the contributions by participants in the WideningParticipation in Clean Energy workshop, held in Brussels during 13-14 March2025. Their insights and expertise provided important context, examples of bestpractices and perspectives that reflected the experiences of a wide range ofstakeholders.
