Fluorinated Gases Hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. Inventory of U.S. greenhouse gas emissions and sinks: 1990–2019. However, the gases differ greatly in the length of their lifetimes, with methane being converted to carbon dioxide over the course of roughly 10 years and nitrous oxide disappearing in slightly more than 100 years. Emissions decreased again from 2010 to 2012 and continued downward largely due to the growing use of natural gas to generate electricity in place of more carbon-intensive fuels. Web update: April 2021. The Scottish Greenhouse Gas Inventory is the key tool for understanding the origins and magnitudes of greenhouse gas emissions in Scotland. Each greenhouse gas has a different lifetime (how long it stays in the atmosphere) and a different ability to trap heat in our atmosphere. Real GDP (thin blue line) is the value of all goods and services produced in the country during a given year, adjusted for inflation. The EPA and the aluminum industry worked together to improve aluminum production efficiency while reducing perfluorocarbon (PFC) emissions. Uses. Call me naive; I believe you do. Totals do not match Figure 1 exactly because the economic sectors shown here do not include emissions from U.S. territories outside the 50 states. Carbon dioxide (CO 2) is the primary greenhouse gas emitted through human activities.In 2018, CO 2 accounted for about 81.3 percent of all U.S. greenhouse gas emissions from human activities. An official website of the United States government. EPA has two key programs that provide data on greenhouse gas emissions in the United States: the Inventory of U.S. Greenhouse Gas Emissions and Sinks and the Greenhouse Gas Reporting Program. Among the various sectors of the U.S. economy, electricity generation (power plants) accounts for the largest share of historical emissions—31 percent of total greenhouse gas emissions since 1990. Fluorinated gases are responsible for 0.34 watts per square meter of radiative forcing. The information presented in this book will be invaluable to the research community, especially social scientists studying climate change; practitioners of decision-making assistance, including advocacy organizations, non-profits, and ...

In that report, methane has a global warming potential of 25, which means a ton of methane emissions contributes 25 times as much warming as a ton of carbon dioxide emissions over 100 years, and that ton of methane emissions is therefore equal to 25 tons of carbon dioxide equivalents. Scientific evidence linking chlorofluorocarbons and other ozone-depleting substances to global ozone depletion led to the initial control of chemicals under the 1987 Montreal Protocol.
Fluorinated gases are sometimes used as substitutes for stratospheric ozone-depleting substances (e.g., chlorofluorocarbons, hydrochlorofluorocarbons, and halons). The larger the GWP, the more that a given gas warms the Earth compared to CO2 over that time period. Data source: U.S. EPA, 20216 As a professor and extension specialist at the University of California, Davis, I have the privilege of working on these issues and helping the public, media and thought leaders better understand the role of agriculture in nourishing our world, while also focusing attention on cleaner air and a healthy climate. Emissions increased at about the same rate as the population from 1990 to 2007, which caused emissions per capita to remain fairly level (see Figure 3). The GHGs trap the sun's heat and hold it, serving as a warm blanket around the planet. perfluorocarbons and sulphur hexafluoride (collectively known as “F-gases”) are small in relation to the other gases, accounting for 2.6% of emissions in 2012. This is a print on demand report. Methane is produced naturally when vegetation is burned, digested or rotted without oxygen.
