Costs of mitigation bearable -Garnaut projections show

8/09/2008 - The costs of reducing greenhouse gas emissions don't look so big when seen from up close.

There is a widespread fear that measures to mitigate Australia's contribution to global warming would wreck the economy.

The best guess of the Garnaut Climate Change Review, updated on Friday with the release of a supplementary draft report on targets and trajectories, is that proposed mitigation measures will cause gross national product (GNP) to grow about one tenth of a percentage point slower over the remainder of the century.
