World Environment Day is observed every year on 5 June - a day designated by the UN to raise awareness of environmental issues.

The theme of World Environment Day 2015 is 'Seven Billion Dreams. One Planet. Consume with Care.'

Italy will serve as the host of the 2015 event, and the celebrations will be organised at the Milan Expo.

"It is an honour for Italy to work together with UNEP in leading the global celebrations for World Environment Day 2015," Italian Minister for the Environment Gian Luca Galletti said. "This year, WED will focus on the need to respect the carrying capacity of the planet and to manage natural resources efficiently—all aspects that are of utmost importance if we really want to ensure prosperity and wellbeing globally."
