Under the United Nations Environment Programme’s (UNEP) Plant for the Planet: Billion Tree Campaign; people, communities, organizations, business and industry, civil society and governments are being encouraged to plant trees and register their tree planting pledges here. The objective is to plant at least one billion trees worldwide each year.

The idea for the Plant for the Planet: Billion Tree Campaign was inspired by Professor Wangari Maathai, Nobel Peace Prize laureate for 2004 and founder of Kenya’s Green Belt Movement, which has planted more than 30 million trees in 12 African countries since 1977. When a corporate group in the United States told Professor Maathai it was planning to plant a million trees, her response was: “That’s great, but what we really need is to plant a billion trees.”
