World Environment Day
Green, for trees planted and land restored, on the United Nations day for the environment.
The colours of World Environment Day
World Environment Day has been held on 5 June since 1974, the date marking the opening of the first United Nations conference on the human environment in Stockholm in 1972. A different country hosts it each year and a theme is set, such as plastic pollution or land restoration. The United Nations Environment Programme, which runs it, has its headquarters in Nairobi. Green is the colour used almost everywhere: for posters, for the shirts of volunteers and for the saplings handed out. In India the day is one of the largest tree-planting occasions of the year, with schools and housing societies planting neem, peepal and other native trees just ahead of the monsoon. Blue is added when the theme is water or oceans.
