Carbon offsets are voluntary donations that can be made to compensate, or offset, greenhouse gas emissions from transport, electricity use, and other sources. In an effort to promote sustainable development and tourism, the Costa Rican Ministry of Environmental Affairs has created a program in which tourists can compensate the carbon emissions from their international flights by investing in programs that preserve and reforest natural areas within Costa Rica. You can find more information on the program’s website (http://www.fonafifo.go.cr/) or ask us.
