FIGURE 1.3 Greenhouse gas emissions in the United States, 1990–2007, in millions of tonnes CO2 equivalent. The “other” greenhouse gas (GHG) emissions shown on the diagram include methane and nitrous oxide, converted to CO2-equivalent units. The 1990 and 2007 point estimates have been rounded to two significant figures.
