Chicago Climate Exchange

The Chicago Climate Exchange (CCX) was a voluntary market for trading carbon credits aimed at reducing greenhouse gas emissions. Companies could buy credits if they exceeded their emission targets and sell them if they emitted less, creating a financial incentive to lower pollution. Established in the early 2000s, it allowed participants to develop and trade emission reduction projects, promoting environmental sustainability while adhering to economic principles. Although it ceased operations in 2010, the CCX was a pioneering effort in climate change policy, illustrating how markets can help address environmental challenges.
