(CNN)Nearly two-thirds of respondents believe that climate change is a “global emergency,” according to a survey of 1.2 million people in dozens of countries around the globe — and many want urgent action to tackle the problem.

The United Nations Development Programme (UNDP), which ran the poll with Oxford University, described it as the largest survey of public opinion on climate change ever conducted. Unusually, it captured the views of more than half a million people under the age of 18, a key but typically hard-to-reach constituency, the organization said.
The “Peoples’ Climate Vote” was undertaken late last year in 50 high, middle and low income countries that together account for more than half of the world’s population over the age of 14, according to the UNDP report.
Across those countries, 64% of people said climate change was an emergency, “presenting a clear and convincing call for decision-makers to step up on ambition,” the report said.
“Of the people that said climate change is a global emergency, 59% said that the world should do everything necessary and urgently in response,” it added. A further 20% backed acting slowly, while 10% thought the world was already doing enough.
While younger people showed the greatest concern over climate change, with 69% of those aged 14-17 saying there is a climate emergency, around two-thirds of those aged 18 to 59 and 58% of those aged 60 and over agreed. This illustrates “how widely held this view has become,” the UNDP said.
Its polling also indicated that majorities backed climate action even when it would have a significant impact on their own country, at a time when much of the world is reeling from the effects of the coronavirus pandemic.

‘Broad support’ for action

Respondents were asked where they would most like to see action, with questions on support for 18 policy options across six areas — energy, economy, transportation, farms and food, protecting people, and nature.
Four climate policies emerged as the most popular globally, with 54% of those surveyed favoring conservation of forests and land, 53% choosing increased use of renewable energy, 52% supporting climate-friendly farming techniques and 50% wanting more investment in green businesses and jobs. The promotion of plant-based diets was the least popular, with only 30% support.
There were “clear calls” for renewable energy even in higher emitting countries such as the United States, Australia and Canada, the UNDP report said.
It also found “strong backing” for action to conserve forests and land in countries with high emissions from deforestation and land-use change, such as Brazil, Indonesia and Argentina.
“The results of the survey clearly illustrate that urgent climate action has broad support amongst people around the globe, across nationalities, age, gender and education level,” Achim Steiner, UNDP administrator, said in a news release.
“From climate-friendly farming to protecting nature, and investing in a green recovery from Covid-19, the survey brings the voice of the people to the forefront of the climate debate. It signals ways in which countries can move forward with public support as we work together to tackle this enormous challenge,” he said.
