World Environment Day is the United Nations day for encouraging worldwide awareness and action to protect our environment. Since it began in 1974, the event has grown to become a global platform for public outreach that is widely celebrated in over 100 countries.

Each World Environment Day is organised around a theme that draws attention to a particularly pressing environmental concern. The theme for 2019 is “Air pollution”.

Every World Environment Day has a different host country, where the official celebrations take place. The focus on the host country helps highlight the environmental challenges it faces and supports worldwide efforts to address them. This year's host is China.

In recent years, millions of people have taken part in thousands of registered activities worldwide. Please sign up on the global website  so we can keep you updated on what’s happening.
