HC Deb 15 May 1992 vol 207 c234W
Mr. Dafis

To ask the Secretary of State for the Environment if he will publish the latest available figures for the difference between the level of emissions and the level the biosphere can safely absorb.

Mr. Maclean

The Intergovernmental Panel on Climate Change estimates that the biosphere and other components of the carbon cycle absorb almost half of current man-made emissions of carbon dioxide. We have no information on the amount of carbon dioxide that the biosphere can safely absorb.
