World GHG Emissions Flow Chart

The document presents a flow chart of global greenhouse gas emissions for 2000, totaling 41,755 MtCO2 equivalent. It identifies Electricity & Heat (24.6%) and Land Use Change (18.2%) as the largest contributing sectors, while Carbon Dioxide (77%) is the dominant gas species.

• Total global greenhouse gas emissions for the year 2000 are estimated at 41,755 MtCO2 equivalent, with Carbon Dioxide (CO2) accounting for 77%, Methane (CH4) for 14%, Nitrous Oxide (N2O) for 8%, and HFCs, PFCs, SF6 for 1%.
• The largest sectoral contributors to global emissions are Electricity & Heat at 24.6%, Land Use Change at 18.2%, and both Agriculture and Transportation at 13.5% each.
• Within the energy sector, the highest emissions come from Electricity & Heat (24.6%), followed by Industry (10.4%), and Fugitive Emissions (3.9%).
