Supplementary green book guidance published in February 2012 recommends taking an ecosystem services approach to assess the impacts of policies and projects on the environment.
This research explores the gaps and overlaps between an ecosystem services approach and current WebTAG guidance; the potential structure of an ecosystem services-based screening exercise; and how more detailed assessment of specific ecosystem services could be carried out. Building on this research, the department aims to integrate an ecosystem services approach in future releases of WebTAG guidance.
