Carbon offsets are the biggest scam going and guess who was heavily involved in selling carbon credits to offset carbon emissions. Why it was
Al Gore who made millions because of his involvement in the Chicago Climate Exchange (now bankrupt) and a similar London based 
company, General Investment Management (GIM).  
This scam was initially started by Enron in the early 1990's and people who invested lost millions when the company went bankrupt.
Before that happened, consumers in the state of California were ripped off for millions by one of Enron's subsidiaries who profited by grossly inflating the price of energy.   The World Wildlife Fund (WWF) and its offspring, the Nature Conservancy are all involved in this scam which involves greenhouse gas reduction and trading system where you can buy carbon credits to offset your supposed carbon emissions.
India and China are exempt from reducing their carbon emissions while you in the West are required to reduce yours or buy carbon
credits.
