Timeline of events: Carbon Credits
1990's - Growing Global Warming ConcernsMore and more scientists concur: the earth is warming up, and excess green houses gases are the likely cause.
1997 - The Kyoto ProtocolThe Kyoto Protocol opened the door to the existence of Carbon Credits. Ratified by at least 55 states, it represented a near global promise to combat carbon build up.
2000's - The Carbon MarketTrading begins in earnest, as companies buy up carbon credits to offset their carbon production, hopefully neutralising the effect of carbon on the environment.
2010's - Collapse of Carbon CompaniesInto the 2010’s, it was becoming obvious that some carbon credit schemes were outright scams, and faith in the market dipped. Some carbon credits schemes went under completely, and are now valued at zero.
