  12. Relative Carbon Emissions Life Cycle Energy CIBSE (2002)

  13. Pollution in China

  14. Air pollution spreads out over eastern China, across the East China Sea towards Japan in October 2004. The haze accumulates in the atmosphere from the burning of carbon-based fuels. Pollution (dark grey) is easy to distinguish from clouds (bright white). Image courtesy of the SeaWiFS Project, Nasa/Goddard Space Flight Centre and Orbimage The World Energy Book Issue 1 Autumn 05
