International environmental action "Earth Hour" will take place on March 27, 2021.

Earth Hour is the most massive environmental action on our planet. The action is aimed at drawing attention to the need for responsible attitude to the nature and to the resources of our planet. Participating countries raise one of the acute environmental topics every year. The campaign culminates in the Earth Hour itself:

Millions of people from 180 countries switch off lights and electrical appliances for 1 hour.

Thousands of architectural monuments close their illuminations, such as Eiffel Tower, Big Ben, and Colosseum.

WWF first arranged the action in Russia in 2009. 16 to 20 million people have been participating in it since 2011. In 2020, Earth Hour was held in a virtual format for the first time and brought together millions of Russians, 11 time zones, and hundreds of localities. In Moscow, according to tradition, every year at the appointed time the illuminations are closed in the architectural ensemble of the Kremlin, Red Square, St. Basil's Cathedral and GUM, as well as over 1,000 other famous facilities in the capital city. Festive events on environmental themes, as well as disabling illumination of iconic buildings and structures take place in 1,000 other Russian cities.

Turn off the lights at 8.30pm local time on March 27. Join the world's largest flash mob!
