The Sochi Olympic organizers are also planning to invest $1.75 billion in energy conservation and renewable energy to offset the remaining greenhouse gas emissions from the use of electricity, air travel and ground transportation.
Other environmental initiatives include the development of “green belts” in the city and reforestation of the Sochi National Park.
The Games’ organizers had previously agreed to a UNEP suggestion to move the bobsleigh and luge tracks away from the Caucasus nature reserve, which is one of the only mountain areas in Europe that remains virtually untouched by human activity.
The organizers commemorated the signing of the agreement by planting trees in several locations in Russia as part of UNEP’s Billion Trees Campaign.
The agency also advised on greening last summer’s Beijing Olympics, which set new records for eco-friendly mass spectator sporting events, according to a UNEP report published in February.
