Human-caused greenhouse gas (GHG) emissions drive climate change. About 60% of GHG emissions come from just 10 countries, while the 100 least-emitting contributed less than 3%. Energy makes up nearly three-quarters of global emissions, followed by agriculture. Within the energy sector, the largest emitting sector is electricity and heat generation , followed by transportation and manufacturing. Land use, land use-change and forestry (LULUCF) is both a source and sink of emissions and key sector to get to net-zero emissions.
