Understanding $CO_2e$
Carbon Dioxide Equivalent ($CO_2e$) is the standard metric used to compare the emissions from various greenhouse gases on the basis of their global-warming potential (GWP). For example, while Methane ($CH_4$) is shorter-lived, it is **25 times** more potent than $CO_2$ over a 100-year period. Our engine normalizes these variables so you get a single, actionable score.
