SASB Code GRI Code Description Response, link or additional information Biodiversity 304-1 Operational sites owned, leased, managed in, or adjacent to, protected areas and areas of high biodiversity value outside protected areas Severn Trent manages its assets and subsequent impact on a number of protected areas across our region. We own around 497 hectares of Sites of Special Scientific Interest in the Severn Trent region and around 5952 hectares in the Hafren Dyfrdwy region, 4480.55 hectares of which are leased to RSPB. 304-2 Significant impacts of activities, products, and services on biodiversity Ecology reports are completed for all construction activities. Where protected habitat or species are known to be present for reactive works, then the relevant surveys are undertaken and we endeavour to right and enhance any impact we have on the environment through our work. Across AMP7, we have WINEP commitment in place to monitor pathways of INNS across our network and investigate options on how to manage or mitigate their impact. 304-3 Habitats protected or restored Our AMP7 Year One Biodiversity ODI resulted in the improvement of 2,632ha against an ODI target of 190.5ha and a Great Big Nature Boost target of 1044.5ha. Works included reducing phosphate outputs from waste water treatment works, catchment management, and managing the water levels at some of our reservoirs to maintain the ecology of the shore, essential for wading birds Severn Trent’s Great Big Nature Boost is our commitment to create or enhance 5,000ha by 2027 for biodiversity. To help us reach this target we are forming partnerships with third parties to enable large scale habitat improvement projects. Partners include RSPB, Warwickshire Wildlife Trust, Nottinghamshire Wildlife Trust, National Trust. As part of our ambition to demonstrate environmental leadership we want to make sure we get the basics right too. We have updated our Environment Strategy and are currently writing biodiversity, national pollinator, and tree strategies.
