A new study from IIASA compared two paths to a 10% emissions cut across 18 countries: cleaner technology (heat pumps, EVs, hydrogen) and demand-side reductions (better insulation, public transit, smarter material use). The demand-side options scored higher across six quality of life measures including income after energy bills, jobs, energy security, fairness, air quality, and climate impact. Surveys in the Netherlands, Brazil, and China found people expected both approaches to improve their lives and found them acceptable. Support increased after participants read plain descriptions of the actual benefits. The findings challenge the assumption that households will resist using less energy. For policymakers, the results suggest demand-side measures deserve a bigger role in national climate plans. They can be sold as comfort, health, and lower bills rather than sacrifice. The study was published in Communications Sustainability.
