Carbon credits are certificates that represent the right to emit one ton of carbon dioxide or the mass of another greenhouse gas. [1] The document discusses carbon credits in India, how buying carbon credits can reduce emissions, and criticisms of the carbon credit system. It explains that carbon credits create a market mechanism for reducing greenhouse gas emissions by allowing companies that emit less than their allotted limit to sell credits to those that emit more. However, the system is not perfect, as it can be difficult to accurately measure and account for emissions. [2] The Kyoto Protocol established carbon credits as a way for countries and companies to meet emission reduction targets, but criticisms remain about whether it adequately addresses the problem of climate change.
