The following identity shows the three essential components of the world's annual emissions of greenhouse gases:

a. Explain the meaning of the first component, GHG/ Energy.
b. Explain the meaning of the second component, Energy/GDP.
c. Explain why world GDP is likely to continue growing over time. How is this related to world population growth?
d. Explain why the second term is likely to fall over time but by less then the growth in world GDP.
e. Given your answer to parts (c) and (d), what is the implication for the part of GHG/Energy if overall GHF emissions are to be reduced significantly?
