Comparison of physically- and economically-based CO2-equivalences for methane.

The article presents a study on the role of methane methane in climate mitigation policies. The study made use of a simplified Global Damage Potential (GDP) to determine the uncertainties in methane. The result of the study shows that the multi-year climate policies and emissions reductions were supplied by a methane carbon dioxide (CO)2-equivalence for the socio-economically-based metrics.
