Majorities of Americans in Every State Support Participation in the Paris Agreement


Most Americans think the U.S. should participate in the Paris Agreement 

In December 2015, officials from 197 countries (nearly every country in the world) met in Paris at the United Nations Climate Change Conference and negotiated a global agreement to limit global warming. On Earth Day, April 2016, the U.S. and 174 other countries signed the agreement, with most of the others following suit since then.

What do American voters in the U.S. and in every state think about U.S. participation in the Paris Agreement? And what do Trump voters think?

Using methods developed for the Yale Climate Opinion Maps, we find that a majority of Americans in every state say that the United States should participate in the Paris Climate Agreement. (For more details about this map, see Methods below.)

2. By a more than 5 to 1 margin, voters say the U.S. should participate in the Paris Agreement.

In a nationally representative survey conducted after the election, we found that seven in ten registered voters (69%) say the U.S. should participate in the COP21 agreement, compared with only 13% who say the U.S. should not. Majorities of Democrats (86%) and Independents (61%), and half of Republicans (51%) say the U.S. should participate (including 73% of moderate/liberal Republicans). Only conservative Republicans are split, with marginally more saying the U.S. should participate (40%) than saying we should not participate (34%).

Methods

Two questions about the Paris climate agreement in two different surveys were posed to survey participants (the percentage of Americans who chose each response is in parentheses):

1. In your opinion, how important is it that the world reach an agreement this year in Paris to limit global warming? (n=1330; October 2015)

  • “Not at all important” (14%)
  • “A little bit important” (9%)
  • “Moderately important” (24%)
  • “Extremely important” (21%)
  • “Not sure” (14%)
  • “Refused” (1%)

2. Do you think the U.S. should participate in this agreement, or not participate? (n=1226; November, 2016)

  • “Should participate” (67%)
  • “Should not participate” (14%)
  • “Don’t know (19%)
  • “Refused” (0%)

To estimate support among Americans in each state, responses to the two questions above were grouped into two categories — support or oppose — as follows:

  • Support = Q1: “A little bit important”, “Moderately important”, “Extremely important”, or Q2: “Should participate”
  • Oppose = Q1: “Not at all important”, or Q2: “Should not participate”

Margins of error for the state data are +/-10%, which includes potential error from the original surveys as well as from the modeling.
