Public opinion is a key determinant of policy change, especially in democracies. Yet, for people in many countries
around the world, climate change is a relatively new idea and involves complex scientific concepts that are
unfamiliar. As climate change becomes an increasingly salient issue globally – relevant to public health, economic
prosperity, and national security – policy and decision makers, the media, educators, and others need to understand
current public levels of climate change awareness and engagement. This Global Factsheets tool, based on our
global survey,
International Public Opinion on Climate Change, 2023 , provides information about people’s climate
change knowledge, beliefs, attitudes, policy preferences, and behaviors in 187 countries and territories worldwide.
The opinion data included in these fact sheets are based on a survey of 139,136 Facebook monthly active users, aged
18 and older, and the margin of error for individual countries and territories ranges from 2 to 5 percentage
points. Interview dates of the survey were August 3 – September 3, 2023. For more information about the survey
question wording and methodology, please visit the associated
Climate Note . We hope you find the data and tool useful, and welcome your feedback to help us
improve future versions.
FOR GEOGRAPHIC GROUPS ONLY
Results for geographic groups are based on combined data from multiple countries and territories that have smaller
populations and/or numbers of Facebook users. Samples from these countries and territories were combined into
“group” scores (i.e., Caribbean, Asian and Pacific Islands, and some countries in Sub-Saharan Africa). The complete
lists of included countries and territories are included in each group factsheet.
