Trends in global CO2 and total greenhouse gas emissions: 2017 report

CO2 emissions and total global greenhouse gas emissions are reported for 2016, based on the latest update of the EDGAR v4.3.2 database, using statistics, where available, up to and including 2016. The conclusion of the report is that, in 2016, total global greenhouse gas (GHG) emissions continued to increase, by about 0.5%, reaching 49.3 gigatonnes of CO2 equivalent. The increase in GHG emissions is mainly due to the rise of non-CO2 emission levels in 2016, which was estimated at around 1%. With a share of about 28%, the non-CO2 GHG emissions are a significant source of global GHG emissions. Of those, methane, constituting about 19% of global emissions, is by far the largest category. Its main sources are fossil fuel production (25%), cattle (23%) and rice production (10%).
