A new study in Nature Sustainability reveals that forcing lifestyle changes through climate policies can backfire, weakening pro-environmental values and sparking political opposition. Researchers surveyed over 3,000 Germans and found stronger resistance to green mandates than to COVID restrictions. The findings highlight the importance of policy design in maintaining public support for climate action.
Published last week in the journal Nature Sustainability, a study by economists Sam Bowles and Katrin Schmelz from the Santa Fe Institute examines the risks of aggressive climate policies. The research, based on surveys of more than 3,000 Germans, shows that mandates restricting personal freedoms—such as bans on urban driving, limits on thermostat temperatures, or curbs on meat consumption—elicit strong backlash. Even among those who care about climate change, these measures were perceived as infringements on liberty.
The study compared reactions to climate policies with COVID-related mandates like vaccines and masks. It found the 'cost of control'—a measure of opposition—was 52 percent greater for climate initiatives. 'I didn’t expect that people’s opposition to [a] climate-mandated lifestyle would be so extreme,' Schmelz said. She noted that higher trust in government in Germany compared to the United States might still lead to more resistance there.
Bowles added, 'Mandates can sometimes get you over a hump and tipping point, but they come with costs.' Behavioral economist Ben Ho of Vassar College, who was not involved, linked the results to tensions between individual liberty and communal safety, calling the connection to COVID responses particularly novel.
Real-world examples illustrate the dangers. In Germany, a 2023 law effectively banning new gas heating systems—dubbed the 'heizhammer'—fueled backlash from far-right parties and contributed to the fall of the center-left government. Climate economist Gernot Wagner of Columbia Business School observed, 'The last German government basically fell because they were seen to be instituting a ban on gas.' The current administration is rolling back the measure.
In the United States, less aggressive policies have avoided similar uproar, but precedents exist. The 2007 Energy Independence and Security Act's phase-out of incandescent light bulbs prompted 2011 repeal bills from the tea party movement. Today, debates over natural gas bans in cities like New York echo these fights, with opponents framing efficiency standards as restrictions.
The authors suggest alternatives like tax incentives, rebates, or higher prices for polluting activities to encourage green behavior without direct control. 'Offering alternatives is helping in enforcing green values,' Schmelz said. Bowles emphasized, 'People don’t feel like they are being controlled by a higher price.' They stress that while mandates like seatbelt laws have succeeded in the past, climate policies face unique challenges without broad consensus on personal benefits.
Ultimately, the study urges policymakers to consider how measures affect public values. 'Ethical commitments and social norms are very fragile and they’re easily destroyed,' Bowles warned, advocating designs that align with citizens' goodwill rather than overriding it.
