Global warming potential (GWP) is a way of measuring the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide. GWP is 1 for CO₂.
Carbon credits are a type of permit that represent one tonne of carbon dioxide removed from the atmosphere. They can be purchased by an individual or company to make up for carbon dioxide emissions that come from industrial production, delivery vehicles, or travel. Carbon credits are one way to offset your carbon footprint and help reduce greenhouse gas emissions.
