Climatism is a social, political, and economic ideology and movement that emerged toward the end of the 20th century and aims to combat global warming, for example through climate change mitigation, so that its impact on people's living conditions is mitigated and ultimately neutralized. More specifically, the idea of net-zero emissions emerged in the 2010s, the notion that an account of emission and capture of greenhouse gases by a certain deadline should show net emissions of zero.
