§ Mr. Trippier
International comparisons of expenditure on environmental protection have been made by the OECD, which will shortly be publishing a report of its findings. The estimation of such expenditure involves many problems of definition, measurement and collection of data. Figures for the United Kingdom indicate that between 1 per cent. and 2 per cent. of GNP is dedicated to environmental protection. Other OECD countries appear to spend a similar proportion, and there are no reliable indications that this has varied greatly over the past two decades.
