A variety of climate action strategies improve people’s quality of life, including strategies that require people to shift their behavior to use less energy, according to a new analysis. The study challenges the conventional wisdom that fighting climate change imposes a burden on the public—and offers a hopeful message about people’s willingness to engage.

In the past, most of the debate about policies to reduce greenhouse gas emissions has centered on cost versus amount of carbon saved. The new study adds quality of life as a third, previously overlooked dimension to the picture.

Researchers used computer simulations of national energy systems to evaluate how six different climate mitigation strategies affect various aspects of quality of life, performing this analysis for 18 countries.

They analyzed one so-called “supply-side” strategy focused on replacing fossil energy with clean technologies and one “demand-side” strategy involving reduced use of energy and materials for each of three major economic sectors: transport, buildings, and industry.

Until now, most research on climate mitigation has emphasized supply-side strategies, in part because of an assumption that demand-side measures would make people’s lives more difficult and thus be unpopular.

That’s not the case. All six climate strategies improve overall quality of life, the researchers found.

Both high-income and low- to middle-income countries see quality-of-life benefits from climate action, challenging the usual narrative that fighting climate change pits countries’ interests against each other. “Framing the climate change mitigation conversation around quality of life could break political stalemates” arising from this mistaken assumption, the researchers write.

The researchers analyzed six different dimensions of quality of life—household income, jobs, health, energy security, fairness, and environmental conditions. Demand-side interventions perform slightly better across a wider range of quality-of-life aspects, the researchers found.

The best performers overall are demand-side interventions: reducing energy use in buildings by beefing up insulation and tweaking thermostat settings, and shifting car trips to other modes of transport like public transit, walking, and cycling.

The researchers also surveyed between 800 and 1,400 residents in three of the countries—the Netherlands, Brazil, and China—making the study one of only a few studies that have provided both objective and subjective data on the quality-of-life dimension of climate action.

In all three countries, people were open to both supply-side and demand-side climate strategies, and expected both to improve their quality of life. “People evaluate demand-side strategies positively, even if there is a tendency to evaluate supply-side strategies even more positively,” the researchers write.

What’s more, sharing evidence about the quality-of-life impacts of the six climate strategies tends to increase people’s support for them, the researchers found.

Overall, the findings suggest that in designing climate policy and selling it to the public, policymakers should emphasize well-being, not just cost-effectiveness—and they shouldn’t shy away from proposing demand-side measures, the researchers say.
