About World Environment Day
World Environment Day is the United Nations’ principal vehicle for encouraging worldwide awareness and action for the environment. Held annually since 1974, the Day has also become a vital platform for promoting progress on the environmental dimensions of the Sustainable Development Goals. With the United Nations Environment Programme (UNEP) at the helm, over 150 countries participate each year. Major corporations, non-governmental organizations, communities, governments, and celebrities from across the world adopt the World Environment Day brand to champion environmental causes.
