Report from a Nordic Expert Meeting on Cost-Effective International Agreements on Air Pollution Control. 21-22 January 1992.

A Nordic meeting on cost-effective international agreements on air pollution control, after discussing papers presented on scientific and economic issues, concluded that for Europe a new sulphur protocol seems more appropriate than an acidification protocol. For the next NOx protocol, however, efforts should be made to take into account both acidification, eutrophication and formation of photochemical oxidants. The meeting also stressed that if various economic instruments, e.g. emission trading, are to be further discussed, the concepts need further elaboration.
