What is
World Environment Day?

A global celebration of nature, 
a day to reconnect with the places that matter most to you.

A Platform for Action
World Environment Day is the United Nations’ most important day for encouraging worldwide awareness and action for the protection of our environment. Since it began in 1974, it 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 or become an agent of change. That ‘something’ can be focused locally, nationally or globally; it can be a solo action or involve a crowd – everyone is free to choose.

The Theme
Each World Environment Day is organized around a theme that focuses attention on a particularly pressing environmental concern. The theme for 2017 is connecting people to nature.

The Host
Every World Environment Day has a different global host country, where the official celebrations take place. The focus on the host country helps highlight the environmental challenges it faces, and supports the effort to address them. This year’s host is Canada.
