Rich Americans produce nearly 25% more heat-trapping gases than poorer people at home, according to a comprehensive study of U.S. residential carbon footprints. Scientists studied 93 million housing units in the nation to analyze how much greenhouse gases are being spewed in different locations and by income, according to a study published Monday in the Proceedings of the National Academy of Sciences. Residential carbon emissions comprise close to one-fifth of global warming gases emitted by the burning of coal, oil, and natural gas.
