CO2 Equivalencies

This is a way to measure and compare the impact of different greenhouse gasses (GHGs) on climate change. GHGs, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20), trap heat in the Earth’s atmosphere, leading to global warming. The concept of CO2 equivalencies allows us to express the warming potential of these gasses in terms of the amount of CO2 that would have the same impact over a period of time (100 years). This way we can compare the relative contributions of different gasses to climate change.
