reservoirs at thousands of locations around the world could accommodate
the pressurized greenhouse gases that the world will continue to produce.
The technology for carbon capture and storage (CCS) currently exists, and
some small projects are currently operating in Saskatchewan and in the
United States. But the process is quite expensive, and there remains
considerable doubt regarding the extent to which the process can be
scaled up to the degree necessary for CCS to play a large role in the
reduction of global GHG emissions.
1 To compute how changes in the various parts of Equation 17-1 are related to each other, note
that for any product Z = X ⋅ Y, the percentage change in Z is very closely approximated by the sum
of the percentage changes of X and Y.
