How the Vote Works

While numerous surveys measure belief in climate change in developed countries, UNDP wanted to reach new audiences and poll countries where less was known about public opinion in this area.

Given UNDP’s unique role in supporting 120 countries to develop their national climate plans (or NDCs) under the Paris Agreement through its flagship Climate Promise initiative, it is also a crucial tool for helping governments gauge public perspectives and experiences on climate change. This support extends to policy priorities at both national and global levels, which could be integral to those national pledges.

THE METHODOLOGY

The Peoples’ Climate Vote 2024 survey was administered by GeoPoll by Computer Assisted Telephone Interviewing (CATI). Sampling was primarily done by Random Digit Dialling (RDD) of mobile phone numbers, with quota management for groups defined by age, gender and education.

Samples were collected from those aged 15 and above and administered in 87 different languages, with an overall response rate was 6.8%. Calls started in September 2023 and finished in May 2024.

The margin of error for percentages quoted in this report will technically vary according to the sample size for each question, country and demographic group being discussed. The country-level estimates have margins of error no larger than + or - 3 percentage points, meaning they are accurate within 3 percentage points of the listed percentage. The margin of error for SIDS and some regions is + or -1, and even lower for big regions and global estimates.

  • There are four countries (Czechia, Greece, Jordan, and the Comoros) which are marked by a * when listed, because the margins of error will be larger and broader reliability of estimates will be somewhat lower.
  • Surveys from Barbados, the Solomon Islands, Papua New Guinea and Vanuatu have a simplified weighting scheme as a result of few responses from certain age and/or education groups and may not adequately reflect the opinions of those groups. For that reason, estimates from those countries are marked by a **
  • Smaller surveys (with less than 490 respondents) were conducted in Kazakhstan, the Netherlands, Poland and Sweden. Due to small overall sample sizes, country-level estimates are not presented in this report, however surveys from these countries do contribute to regional and global estimates.

Response rates by country, country groupings, and more information on these points can be found in the extended methodology View Report.
