Abstract
In organizing and collecting environmental statistics this strategy should be followed: First, define the environmental problem, then decide on the analyses and methods needed to provide information to decision makers, and, only when this demand is relatively clearly defined – collect the necessary data. The point is, of course, to avoid putting resources and effort into detailed modelling of “inessential” phenomena, while at the same time making certain that statistics gathered are useful and treated in a disciplined manner.
An important use of environmental statistics is for policy analysis, and often economic models form a sound basis for such analysis. Thus, the format of environmental statistics should be compatible with that required by the economic modelling tools.
Many countries' planning procedures are rather fragmented, with responsibilities for economic development, environmental standards, etc., distributed among several more or less independent ministries and agencies. Macroeconomic models can be used to ensure consistency among various planning activities with regard to behavioural assumptions or expectations about the future development of key economic variables.
