World Environment Day in 2026 focused on climate change—on the urgent signals the Earth is sending and the signals we choose to send in response. UNEP’s global campaign calls on everyone to step in, go further, and help steer a world already in motion. The question is no longer whether change is coming, but how humanity guides it and how fast.

The event was hosted by the Republic of Azerbaijan.

Its landscape spans two major climate zones—subtropical and temperate—and includes eight distinct climate types, from subtropical forests to alpine ecosystems, supporting rich biodiversity.
