A platform for action
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.
The people's day
Above all, World Environment Day is the "people's day" for doing something to take care of the Earth. That "something" can be local, national or global. It can be a solo action or involve a crowd. Everyone is free to choose.
Each World Environment Day is organized around a theme that draws attention to a particularly pressing environmental concern. The theme for 2020 is biodiversity.
Every World Environment Day has a different host country, where the official celebrations take place. The focus on the host country highlights the environmental challenges it faces and supports worldwide efforts to address them. This year's host is Colombia in partnership with Germany.
