How much carbon dioxide is produced when different fuels are burned?

Energy Information Administration FAQs:

"Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content.

Pounds of CO2 emitted per million British thermal units (Btu) of energy for various fuels:

How much coal does the U.S. export and import?

The United States is a net exporter of coal. However, some coal is still imported, mostly for power plants on the eastern and southern coasts of the country, where it is cheaper to ship in coal by sea from South America than transport it from mines in the northern and western United States.1

In the fourth quarter of 2017, the U.S. exported 28.2 million short tons of coal (14.6% of total production)2 to dozens of countries around the world; the largest markets were India (15.4% of all exports), South Korea (8.1%), and Brazil (7.8%).2

EARTH: The Bright Future for Natural Gas in the United States

Hydraulic fracturing, or "fracking," has changed the energy landscape. We can now affordably produce natural gas from previously inaccessible rock formations, which has led to increasing natural gas consumption. Thanks to its low prices and abundant domestic supply, natural gas may have a chance to overtake coal as the primary energy source for electricity in the United States.

EARTH: Trade Imbalance, America Exports Emissions to China

America has made great strides in recent years to reduce carbon emissions by increasing efficiency and turning to other, low or non-carbon energy sources. Meanwhile, carbon emissions in China have grown dramatically during that same time. EARTH looks at this disparity and asks the difficult questions about who is to blame when the coal China is burning is imported from "cleaner" countries and the emissions are produced to manufacture goods exported back to places with lower emissions.

AGI Publishes Coal and the Environment

To highlight the importance of coal in our daily lives and the environmental concerns that are associated with its mining and use, the American Geological Institute (AGI) has published "Coal and the Environment" (ISBN 0-922152-77-2) as part of the Environmental Awareness Series. Produced in cooperation with the Illinois Basin Consortium, the U.S. Department of Energy, and the Office of Surface Mining with additional support from the AGI Foundation and the U.S. Geological Survey, "Coal and the Environment" discusses the mining, processing, transportation, use, and environmental aspects associated with this important resource.
