Zimbabwe Greenhouse Gas (GHG) Emissions 1970-2021

Total greenhouse gas emissions in kt of CO2 equivalent are composed of CO2 totals excluding short-cycle biomass burning (such as agricultural waste burning and Savannah burning) but including other biomass burning (such as forest fires, post-burn decay, peat fires and decay of drained peatlands), all anthropogenic CH4 sources, N2O sources and F-gases (HFCs, PFCs and Sulfr hexafluoride). Zimbabwe greenhouse gas (ghg) emissions for 2012 was 72,057.80, a 0.69% increase from 2011.
