How Carbon Emissions Are Measured
Greenhouse gas footprints are quantified in metric tonnes of Carbon Dioxide equivalent ($CO_2e$) per year. This incorporates other warming gases like methane ($CH_4$) and nitrous oxide ($N_2O$).
This calculator integrates localized country electricity power grid mix indexes (such as carbon-heavy coal grids vs. clean hydro mixes) and home waste recycling metrics to provide highly accurate net emission estimates.
