The nations of the world agreed in 1992 at the Earth Summit in Rio de Janeiro to take steps to stabilize and reduce the net emissions of carbon dioxide. Trees have often been discussed in this context since, by fixing carbon, they offset carbon emissions by fossil fuels and can be used as an alternative renewable biofuel, replacing the use of fossil fuels. The degree to which tree-planting in the Prairie Provinces will be adopted as a carbon offset in the coming years will depend on technology, programs, policies and legislation.

Canada has agreed to reduce carbon emissions to 1990 levels by the year 2000. Tree planting can be seen as one of the ways of achieving this goal. The ability of trees on the Canadian prairies to offset rising levels of carbon dioxide in the atmosphere is the topic of this report.
