Carbon Tracker Initiative is a London-based independent think tank that has transformed how financial markets understand climate risk. Founded in twenty eleven, the organization introduced the concepts of unburnable carbon, stranded assets, and the carbon bubble to global investors. Its research shows that most proven fossil fuel reserves cannot be burned without breaching safe climate limits. Institutions managing over forty trillion dollars in assets have made fossil fuel divestment commitments, partly influenced by Carbon Tracker's pioneering financial risk analysis.
