In its most recent annual report, the U.S. Environmental Protection Agency (EPA) reported that the greenhouse gas emissions went up by 2% [1].
Figure 1 illustrates the changes in carbon dioxide emissions over the past few decades, while Figure 2 illustrates the contributions of each sector of the economy to such emissions.
Figure 3 illustrates the distribution of the greenhouse gas emissions from commercial sectors, excluding power plants, O&G, mining, P&P, and waste, across the continental U.S.
