The observatory's location in Hawaii was chosen specifically due to the cleanliness of the air that produces more accurate measurements than what would be measured close to areas with higher carbon dioxide emissions. (gracelinks.org)
Because lower rank coals have relatively high carbon dioxide emission factors, increased use of these coals caused the national average carbon dioxide emission factor to rise from 206.5 pounds per million Btu in 1980 to 207.6 pounds per million Btu in 1992. (eia.gov)
