Costa Rica aims to be fully carbon neutral by at least 2050. There are plans to do it even faster, namely by 2021 (the 200th anniversary of its independence) In 2004, 46.7% of Costa Rica's primary energy came from renewable sources, while 94% of its electricity was generated from hydroelectric power, wind farms and geothermal energy in 2006. A 3.5% tax on gasoline in the country is used for payments to compensate landowners for growing trees and protecting forests and its government is making further plans for reducing emissions from transport, farming and industry.
