Carbon credits are a component of trading schemes implemented to mitigate global warming. They provide a way to reduce greenhouse effect emissions by capping total annual emissions and letting the market assign a monetary value to any shortfall through trading in similar way as the market values stocks of publicly trading companies. Credits can be exchanged between businesses or bought and sold at the prevailing market price. They can be used to finance carbon reduction schemes between trading partners and around the world.
