Carbon Credits

Carbon offsets are financial contributions targeted at projects that take CO₂ out of the atmosphere or prevent more from being added. You can purchase offsets to balance travel-generated CO₂, typically one offset per ton of gas emitted. The number of tons is based on how many miles you travel, whether by car or plane, and the amount of fuel used. Carbon offsets fund projects that create renewable energy sources, as well as "carbon sequestration" efforts like planting trees.
