Global Warming Potential (GWP) is a measure that allows comparison of different greenhouse gases based on their heat-trapping ability relative to CO₂. While carbon dioxide is the most abundant greenhouse gas, others like methane (CH₄) and nitrous oxide (N₂O) are far more potent per molecule. Methane has a GWP of 28 over 100 years — meaning one kilogram of methane traps as much heat as 28 kg of CO₂.
This calculator converts emissions of multiple greenhouse gases into a single CO₂ equivalent (CO₂e) metric, enabling meaningful comparisons. The GWP framework is central to the Kyoto Protocol and Paris Agreement and is used by organizations worldwide for emissions reporting under the GHG Protocol.
The formula is: CO₂e = Σ(mass_i × GWP_i)
GWP values (AR5, 100-year): CO₂ = 1, CH₄ = 28, N₂O = 265, SF₆ = 23,500. The 20-year GWP gives higher weight to short-lived but potent gases like methane (GWP₂₀ = 81).
Results expressed in CO₂e allow direct comparison. Even small quantities of high-GWP gases like SF₆ (used in electrical equipment) can dominate total emissions. Prioritize reducing the gas with the highest CO₂e contribution.

Global Warming Potential is a quantitative measure used in environmental science and ecology. It represents key metrics that help researchers, policymakers, and individuals understand environmental impacts. The specific definition and measurement methodology are established by international scientific organizations and regulatory bodies.
Why is methane worse than CO₂ involves analyzing relevant parameters using established scientific methodologies. Our calculator applies peer-reviewed formulas and standard emission factors to provide accurate results. The specific approach varies by parameter but follows guidelines from organizations such as the EPA, IPCC, and relevant scientific bodies.
