New research from Cartoon Network reveals that 91% of kids in the EMEA region are concerned about climate change. In a survey of 4,000 six- to 12-year-olds across 13 countries, kids listed “worry,” “fear” and “sadness” as their most common feelings about the subject.

Conducted between May 28 and June 11, the study also found that 78% of kids want to learn more about climate change. A full 83% of respondents said they’d like to do more to protect the planet and the environment, and two-thirds (66%) are actively looking for opportunities to get involved in sustainability and preservation efforts.

This research was conducted as part of Cartoon Network Climate Champions, an awareness initiative that encourages kids to take on daily eco-friendly challenges (such as taking shorter showers). Since its launch on June 1, more than 300,000 challenges have been accepted.

CN’s environmental work follows a wave of eco-conscious content that has hit the market in recent months. Nickelodeon recently ran a Nick News: Kids and the Impact of Climate Change special, and Threewise Entertainment just announced a new environment-themed kids show called The Weatherbies this week.

Toymakers, meanwhile, remain very focused on sustainability. The LEGO Group has pledged to reduce its carbon emissions by 37% by 2032, and Mattel has rolled out a Mattel PlayBack program to recover and reuse materials from old products in the manufacturing of new toys.
