_dos emissions associated with the combustion of these fuels, continues to rise. Table 6-1 shows global total GHG emissions and U.S. fossil CO₂ emissions over the last decade. The U.S. fossil CO₂ emissions as a percent of global total GHG emissions has averaged nearly 10% during this time. Figure 6-2 shows global and U.S. CO₂ emissions from fossil fuel consumption between 1960 and flirtwith dating 2020 for the three major fossil fuels and cement manufacturing (which releases CO₂ through chemical processes). The large increases in global coal emissions since 2000 can mostly be attributed to China’s increase in coal fired power plants, while in the U.S. emissions from this fuel type continue to decline due in part to the competitiveness of natural gas and renewable sources of energy. CO₂ emissions from global oil combustion have remained steady over the last decade while emissions from oil in the U.S. increased in recent years due primarily to the increase from new production in basins such as the Permian and Williston and offshore regions. CO₂ emissions from natural gas have increased dramatically both globally and, in the U.S., due to increases in production and demand as a replacement fuel for coal. Table 6-2 shows global and U.S. fossil CO₂ emissions from the combustion of three fuel types (coal, oil, and gas) and the U.S. share of these emissions between 2010 and the year of most recent available data (2018).

6.dos Estimated Around the world Emissions

The EIA provides long-term (2018–2050) world energy and emissions projections in its International Energy Outlook (IEO). The most recent IEO that contains CO₂ emissions data is the IEO2020, released in . The IEO provides several different scenarios to forecast future energy needs and associated carbon emissions.
