WebJan 30, 2024 · The usual way of comparing greenhouse gases is through a single conversion factor, called the global warming potential, which uses a somewhat arbitrarily chosen time horizon of 100 years. For methane, this is usually given as a factor of 25 (that is, methane is 25 times more potent than carbon dioxide).

Therefore, the choice of the time horizon has implications on the relative weight of different gases when applying the GWP metric. Short-lived gases get more weight when a short time horizon is chosen, long-lived gases when the choice is a long time horizon. fairfax county car tax rateGlobal warming potential (GWP) is 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 (CO2). GWP is 1 for CO2. For other gases it depends on the gas and the time frame. Carbon dioxide equivalent (CO2e or CO2eq or CO2-e) is calculated from GWP. For any gas, it is the mass of CO2 that would warm the earth as much as the mass of that gas.
