Carbon dioxide (CO 2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH 4) and nitrous oxide (N 2O) are also emitted.

Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA.Ģ U.S. Exit Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. In: Climate Change 2007: The Physical Science Basis. To learn about projected greenhouse gas emissions to 2020, visit the U.S. greenhouse gas emissions increased compared to 2013 levels. This increase was due to a number of factors, including: cold winter conditions resulting in an increase in fuel demand, especially in residential and commercial sectors an increase in transportation emissions resulting from an increase in vehicle miles traveled and an increase in industrial production across multiple sectors that also resulted in increases in industrial sector emissions. From year to year, emissions can rise and fall due to changes in the economy, the price of fuel, and other factors. greenhouse gas emissions have increased by about 7 percent. In the United States, since 1990, managed forests and other lands have absorbed more CO 2 from the atmosphere than they emit. Land Use and Forestry (offset of 11 percent of 2014 greenhouse gas emissions) – Land areas can act as a sink (absorbing CO 2 from the atmosphere) or a source of greenhouse gas emissions.Agriculture (9 percent of 2014 greenhouse gas emissions) – Greenhouse gas emissions from agriculture come from livestock such as cows, agricultural soils, and rice production.Commercial and Residential (12 percent of 2014 greenhouse gas emissions) – Greenhouse gas emissions from businesses and homes arise primarily from fossil fuels burned for heat, the use of certain products that contain greenhouse gases, and the handling of waste.Industry (21 percent of 2014 greenhouse gas emissions) – Greenhouse gas emissions from industry primarily come from burning fossil fuels for energy, as well as greenhouse gas emissions from certain chemical reactions necessary to produce goods from raw materials.Over 90 percent of the fuel used for transportation is petroleum based, which includes gasoline and diesel. Transportation (26 percent of 2014 greenhouse gas emissions) – Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes.Approximately 67 percent of our electricity comes from burning fossil fuels, mostly coal and natural gas. Electricity production (30 percent of 2014 greenhouse gas emissions) – Electricity production generates the largest share of greenhouse gas emissions.The primary sources of greenhouse gas emissions in the United States are: This annual report estimates the total national greenhouse gas emissions and removals associated with human activities across the United States. emissions by publishing the Inventory of U.S. 1 The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.ĮPA tracks total U.S. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. Greenhouse gases trap heat and make the planet warmer. Greenhouse Gas Emissions and Sinks: 1990–2014. * Land Use, Land-Use Change, and Forestry in the United States is a net sink and offsets approximately 11 percent of these greenhouse gas emissions.Īll emission estimates from the Inventory of U.S. Total Emissions in 2014 = 6,870 Million Metric Tons of CO 2 equivalent
