Costa Rica is encouraging tourists to offset the carbon footprint they generate from flights and overland travel in its bid to promote sustainable tourism and become one of the world’s only carbon-neutral countries. 
The initiative, called the Pura Vida Pledge, seeks a voluntary donation from travelers, and contributions will go towards environmental projects throughout the country, such as planting forests, regenerating natural spaces and implementing agroforestry systems on local farms, which allows trees to grow on the same land as crops.
