Public Support for International Climate Action

A September 2021 survey of 898 registered U.S. voters shows broad support for international climate action, including a 73% approval rate for the U.S. pledge to reduce carbon pollution by 50% by 2030. While 66% of voters believe the U.S. should reduce emissions regardless of other countries' actions, there is even stronger consensus that developing countries (81%) and other industrialized nations (74%) should do more to address global warming. Support for providing financial and technical aid to developing countries for mitigation (66%) and adaptation (61%) has increased since March 2021, though significant partisan divides remain, particularly among conservative Republicans.

• A majority of registered U.S. voters believe that both the United States and other nations must increase their efforts to combat global warming. Specifically, 81% believe developing countries should do more, 74% believe other industrialized countries should do more, and 66% believe the United States should do more.
• There is significant support for U.S. climate leadership and independent action; 66% of registered voters think the U.S. should reduce greenhouse gas emissions regardless of other countries' actions, representing a 5 percentage point increase since March 2021. Additionally, 73% support the U.S. government's pledge to cut carbon pollution by 50% by 2030.
• Registered voters show increasing support for providing international aid to developing countries for both climate mitigation and adaptation. Support for financial and technical aid to limit emissions (mitigation) rose to 66% (+8 percentage points since March 2021), and support for aid to prepare for global warming impacts (adaptation) rose to 61% (+6 percentage points).
• A strong majority of registered voters (78%) support the United States using pressure to encourage other countries to reduce their carbon pollution, a position supported by 80% of liberal/moderate Republicans and 51% of conservative Republicans.
