People in affluent countries around the world are willing to tax themselves to address climate change and ease poverty, as demonstrated by a recent global survey showing strong support for climate tax.

That idea defies conventional political wisdom, which typically holds that people hate taxes. It emerged in a survey of 40,680 people in 20 nations that found strong support for a carbon tax that would transfer wealth from the worst polluters to people in developing nations. Most of them support such policies even if it takes money out of their own pocket.

Adrian Fabre, lead author of the study published in Nature, wasn’t surprised by the results. He studies public attitudes toward climate policy at the International Center for Research on Environment and Development in Paris, and said this is the latest in a long line of studies showing that climate-related economic policies enjoy greater support, on the whole, than people assume.

This study asked people how they’d feel about a global carbon tax: The larger an individual’s contribution to climate change, the more they’d pay. In exchange, everyone in the world would receive about $30 per month. “People with a carbon footprint larger than the world average would financially lose, and those with a carbon footprint lower than the world average would win,” Fabre said.

The survey included 12 high-income countries and eight “middle-income” countries like Mexico, India, and Ukraine. The researchers surveyed at least 1,465 people in each nation over several weeks in May 2024. Japan showed the highest support, with 94 percent of respondents backing the idea of linking policies that combat inequality and climate change.

That said, the policy was least popular in the United States, where the average person is responsible for about 18 tons of CO2 a year. About half of Americans surveyed supported the tax. (Three in 4 Biden voters favored the idea. Among Trump voters, just 26 percent did. In contrast, support ran as high as 75 percent across the European Union, where per-capita emissions are 10 tons. “We found that people in high-income countries are willing to let go of some purchasing power, if they can be sure that it solves climate change and global poverty,” Fabre said. Americans would end up foregoing about $85 a month, according to the study.
