Theme for 2026: Now for Climate

The planet doesn’t argue. It doesn’t negotiate. It sends signals—rising seas, raging wildfires, heatwaves, melting glaciers.
We said 1.5°C was the limit. We are crossing it.
For decades, the world has heard the climate story—warnings, targets, distant deadlines. Too often, the response has been clouded by noise: delay, distraction, denial.
But listen closer now. Beneath the noise, another signal is rising. Solar panels stretch across rooftops. Wind turbines line the horizon. Cities are being redesigned for people. Forests are being replanted. Positive tipping points are taking root in every corner of the planet.
#WorldEnvironmentDay 2026 focuses on climate change—on the urgent signals the Earth is sending and the signals we choose to send back. UNEP’s global campaign calls on all of us to step in #NowForClimate, and steer a world already in motion. See how you can get involved.
