The NSW Government has a strong commitment to including the environment in decision making through valuation of changes in environmental quality. The ENVALUE environmental valuation database, developed by the NSW EPA and first released in 1995, is a systematic collection of environmental valuation studies presented in an on-line database. It is expected that the ENVALUE database will assist decision makers in government and industry as well as academics, consultants and environmental groups, to incorporate environmental values into cost-benefit analyses, environmental impact statements, project appraisals and overall valuation of changes in environmental quality.

Using information from this database

The transfer of estimates from studies in the database to other sites where environmental assessment is taking place is called benefit transfer. While this presents a powerful and low-cost means to include environmental values in decision making, care must be taken in transferrring database values to other sites. It is seldom satisfactory to directly transfer aggregate benefit estimates from one site to another. The usefulness of transferring the estimates contained in the database is dependent on the soundness of the methodology used to transfer them and the similarity of the subject site to the study site. While there are limitations in using benefit transfer to derive a precise dollar value for impacts, it can provide an indication of the likely magnitude of environmental values.

The database provides guidance on transferring estimates to other sites. Various studies on the topic of benefit transfer are also included in the database in the 'Conceptual Studies' section.

The values estimated by the original studies have been converted into A$ 2002 values and can be shown in other currencies as an option. This function allows for easier comparison between sites and with today's values.

The summaries and results reported in the database were subject to a process of peer review by experts in the field of environmental valuation. The following people were part of the study review process:

Dr David James - Director, Ecoservices Pty Ltd
Associate Professor Jack Sinden - University of New England
Professor Dodo Thampapillai - Macquarie University
Dr Don Gunasekera - Productivity Commission
Mr Joe Motha - Australian Bureau of Transport Economics
Associate Professor Jeff Bennett - University of New South Wales
Dr Franzi Poldy - formerly of the Bureau of Transport and Communications Economics
Mr Roger Rose - Chief Research Economist, Australian Bureau of Agricultural and Resource Economics
Mr Charles Jubb - Principal Economist, formerly of the Australian Bureau of Industry Economics

The NSW DECC has taken care to ensure the data presented in ENVALUE are an accurate representation of the source studies, however the DECC accepts no responsibility for results obtained from use of the database by third parties.
