29 percent of survey respondents said they'd pay $20 per month to reduce greenhouse emissions, and 20 percent said they'd pay $50 a month. The $20 threshold is a significant one, as it's the cost that the government estimates the damages from climate change would be on each household in the country. Still, the negatives in this study are hard to ignore: despite the fact that 77 percent of respondents said they think climate change is happening and 65 percent said the government should do something with it, that 42 percent who wouldn't even pay a buck a month to do something about it is hard to ignore.

Perhaps not surprisingly, party affiliation was a big divider in how people responded to this survey. Democrats were "consistently" willing to pay more than Republicans, and they were also far more likely to believe in the effects of climate change in the first place. 84 percent of Democrats thought that the government should do something about climate change, versus only 43 percent of Republicans.

Still, one of the directors from the Energy Policy Institute at the University of Chicago is rather positive about the survey's data. In The New York Times, Michael Greenstone writes that "many people are willing to pay real money for a carbon policy. In fact, on average, Americans appear willing to pay more than a robust climate policy is projected to cost." That's a good spin on things, but Greenstone also notes that plenty of respondents may have said they're willing to pay more than they actually would if the time came to open their wallets.
