U.S. Carbon Dioxide Emissions from Energy Sources 2000 Flash Estimate 

This flash estimate is based on data published in the Monthly Energy Review of May 2001 and the Petroleum Supply Annual 2000.
All data should be considered preliminary.

Note: The carbon dioxide emissions are denominated in millions of metric tons of carbon (MMTC). 
To convert to carbon dioxide emissions, multiply the carbon amounts by 3.667.

2000 U.S. Energy Carbon Dioxide Emissions

• U.S. carbon dioxide emissions from the burning of fossil fuels in 2000 were up 2.7 percent from the 1999 levels - moving from 1,517 to 1,558 million tons of carbon (MMTC).
• The 2.7 percent growth rate in energy-related carbon dioxide emissions is the largest since 1996, when a was 3.6 percent
• Based on more recent data, the estimate for 1999 carbon dioxide emissions has also been revised upward by 6 MMTC resulting in a 1.5 percent growth m e from 998 rather than the 1.0 percent reported last year.
• During the 1990 to 2000 time frame, energy-related carbon dioxide emissions grew by 16 percent (209 MMTC), less half the rate of growth in the economy, which grew by 39 percent
• Among all end-use sectors in 2000, carbon dioxide emissions growth in the residential and commercial sectors grew the greatest, at 3.2 and 3.9 percent, respectively, as colder weather increased the demand for heating fuels.
• Transportation-related carbon dioxide emissions, which account for about a third of total carbon dioxide emissions, increased by 2.6 percent in 2000 as a strong economy fueled increased demand for travel.

Factors Influencing Increased Growth in 2000 Energy-related Carbon Dioxide Emissions

• A colder winter heating season increased the demand for heating fuels, which in turned raised carbon dioxide emissions.
• Hydroelectric power generation, which produces no carbon dioxide emissions, was down by 14 percent and displaced in large part by fossil-fueled power generation, which results in carbon dioxide emissions.
• GDP growth was very strong at 5.0 percent and represents the highest annual growth rate experienced during the 1992-2000 economic expansion.

Energy-Related Carbon Dioxide Emissions in Perspective

• As the pie chart on the next slide Indicates, In 1999 energy-related carbon dioxide emissions contributed 81 percent of total greenhouse gas emissions when weighted on a carbon equivalent basis. Other, non-energy-related, carbon dioxide emissions contributed another 2 percent. Methane emissions were 9 percent of the total and nitrous oxide emissions contributed 6 percent. Other gases, including Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs) and Sulfur Hexafluorlde(SF₆), made up 2 percent of the total.
