One carbon credit is generally accepted as equivalent to 1000 kg (or 1 metric tonne) of carbon dioxide (CO2) equivalent.
Carbon credits represent a measurable amount of greenhouse gas emissions reduced, avoided, or sequestered, standardized to 1 tonne of CO2 equivalent.
Carbon credits are a key component of carbon trading schemes, designed to reduce greenhouse gas emissions. They allow entities that reduce emissions below their cap to sell credits to those who exceed their cap, creating a market incentive for emission reduction. While often expressed in CO2 equivalent, this includes other greenhouse gases weighted by their global warming potential.
