EVL Tool

The Environmental Value Look-Up (EVL) Tool is a searchable database which contains indicative monetary values for a range of environmental impacts. The unit values in the tool are based on a review of over 350 UK valuation studies that have been conducted since 2000.

The EVL tool was developed for Defra by eftec to help analysts take better account of environmental impacts in policy and project appraisals.

The EVL Tool is intended:

  • As a first-cut, rapid analysis of the economic values of environmental impacts; and
  • For including secondary or incidental environmental impacts in appraisals that might otherwise be overlooked.

The video below gives you a quick introduction about how to use the EVL Tool.
