Global anthropogenic emissions (excl. biomass burning)

Figure 2. Global anthropogenic methane emissions (excluding biomass burning) from historical inventories and future projections (in Tg CH4 yr-1). USEPA and GAINS estimates have been linearly interpolated from the 10- or 5-year original products to yearly values. After 2005, USEPA original estimates are projections.
