Carbon offset#Voluntary market

Voluntary Market is the name of the markets or countries in which deal without obligation of nation states initiatives at country level, and from the industry itself to reducing CO2 emissions in industry or traffic. The aim here is that an emissions trading is possible ( emissions trading).

Similar to the Kyoto Protocol, sometimes, by extension, can build a kind of own contribution with a voluntary system for emission control, for example, in the U.S. states of California, Wisconsin, New Hampshire, Massachusetts, the New England States, or in Canada, the eastern provinces, without that the national government had the Kyoto Protocol signed or without a national emissions trading is.
