Greenhouse gases come in two basic flavors: carbon dioxide from fossil fuels, and emissions from land use -- agriculture, forests, peat bogs, and waste management. Fossil fuels are primarily used for energy in three sectors: buildings, industry, and transportation. Transportation is almost entirely oil-based -- according to the International Energy Association, about 0.1 percent of transportation energy currently comes from electricity.
Just to make things complicated, people use fossil fuels to make electricity to use in buildings and industry. Well, actually, we use fossil fuels to make electricity -- and -- we use fossil fuels to make heat to use in buildings and industry. In my previous post, I presented some pretty exciting tables summarizing this global state of affairs (and the accompanying Google workbook). Now, in part 2, a detailed look at building, industry, transportation, and land-use emissions:
