Research to produce look-up tables of marginal ecosystem values for initial appraisal within cost-benefit analysis

Searchable spreadsheet of environmental valuation (monetary) estimates drawn from the environmental economics literature. In order to increase the practical use of environmental valuation in Government appraisals, this project will produce a suite of unit / marginal values for non-market environmental impacts with accompanying guidance, drawing on the best of recent literature. These “entry-level” values will make it much easier for non-specialist Government economists to make an initial assessment of potential environmental costs and benefits in social cost-benefit analysis, following HM Treasury Green Book principles. Subject to subsequent review and approval, these “look-up” tables of unit values will be incorporated by Defra in Supplementary Green Book Guidance on valuing environmental impacts.
