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.
