A list of the countries with the biggest share of Climate Change deniers and believers.


First published in December 2020.


Climate Change Deniers

According to YouGov, Indonesia and the U.S. are the countries with the highest shares of climate change deniers.

In a survey carried out in July and August, 21% of Indonesians and 19% of Americans said that climate change was not real or that humans were not responsible. While only 3% of Indonesians said that climate change was not happening at all, that number was 5% in the United States. The number of outright deniers was just as high in several countries in the survey, even though they scored lower on overall climate change denial.

Other countries with high rates of deniers were Saudi Arabia and Egypt, two more countries reliant on fossil fuels for exports or use at home. India, which shares rank four, is a notable example of a country dealing with fake news and the spread of conspiracy belief lately, which could have contributed to the result.

Climate Change Believers

Out of the eight countries with the highest share of inhabitants saying that they believe in man-made climate change, six are located in Europe.

Greece had the highest share of respondents saying that climate change was happening and that humans were mainly or partly responsible in a recent survey by YouGov. 91% of Greeks agreed with the statement, followed by 88% in Brazil.

These findings are consistent with a report showing Europe at the forefront of climate change response.

Greece has in fact been no stranger to the effects of climate change. The already warm and dry climate of the Mediterranean country has intensified to include more extremely hot and especially dry episodes. The Greek authorities therefore believe that they will feel the impact of climate change in the country sooner rather than later. Tourism and agriculture, both important sectors to the country’s economy, are expected to be impacted.

Where Belief in Climate Change is Highest & Lowest

South Korea has a high share of people who believe that human activity has an influence on climate change. 86% said so in a survey by Ipsos which quizzed 20,590 people aged 16-74 in 29 countries. The result was the highest after Hungary, where 91% agreed with the statement.

The United States, on the other hand, remains one of the countries where fewer people hold the same belief. Only 66% of respondents in the U.S. believed that human activity is the principal driver of climate change.

Notably, Japan ranks below the United States with only around half respondents (53%) agreeing that humans are contributing to climate change and 30% choosing to remain neutral on the question.🔷
