Abstract
This document summarises key policy-relevant scientific findings arising from the ‘INSITEs Into: Environmental Restoration and Net Gain’ webinar held on 18th April 2023. The webinar featured several INSITE projects, including CHASANS, DREAMS, Synthesis, and FuECoMMS, each contributing valuable insights into the connectivity and effects of man-made structures in the North Sea. One notable consensus emerging from INSITE is the recognition that complete decommissioning and removal of MMS has a negative impact on preserving and enhancing ecosystem services. The scientific consensus is that it is beneficial to consider options such as partial removal or leaving structures intact, as these structures can support biodiversity and restore ecosystems in a manner similar to natural complex ecosystems. These projects offer crucial policy-relevant evidence to guide the achievement of environmental restoration and Marine Net Gain (MNG) objectives while expanding offshore energy infrastructure.
