Public Support for International Climate Action, March 2021


Executive Summary

In March 2021, President Biden officially invited 40 world leaders to the Leaders Summit on Climate that he will host on April 22nd (Earth Day) and 23rd, 2021. The overarching goal of the summit is to underscore the urgency – and the economic benefits – of stronger climate action. As context for the summit, this report describes how registered voters in the United States view a variety of policies related to international climate action. This survey was fielded from March 18 – 29, 2021, drawing on a representative sample of the U.S. population (n = 1,037; including 922 registered voters). This executive summary reports the results from all registered voters, while the report breaks the results down by political party and ideology.

  • Most registered voters (61%) think the United States should reduce its greenhouse gas emissions, regardless of what other countries do.
  • About eight in ten registered voters (79%) think developing countries (such as China, India, and Brazil) should be doing more to address global warming.
  • About seven in ten registered voters (71%) think other industrialized countries (such as England, Germany, and Japan) should be doing more to address global warming.
  • About two in three registered voters (65%) think the United States should be doing more to address global warming.
  • Seven in ten registered voters (70%) support U.S. participation in the Paris Climate Agreement.
  • More than half of registered voters support providing financial aid and technical support to developing countries to limit their greenhouse gas emissions (i.e., mitigation, 58%) and to help them prepare for the impacts of global warming (i.e., adaptation, 54%).
  • Three in four registered voters (75%) support the United States pressuring other countries to reduce their carbon pollution.
