St John’s College has provided general support for ambitious targets in the Local Plan and made that clear in its responses to other sections of the Plan. From experience of recent proposals, biodiversity net gain is an area where it is particular important that requirements are demonstrably deliverable in Greater Cambridge. The Topic Paper on Biodiversity seeks to provide justification for the proposed minimum 20% biodiversity net gain requirement, above the 10% requirement in the Environment Act. That 10% is in itself a transformational change. The Topic Paper focusses on the benefits of a 20% requirement rather than its practical deliverability, and it acknowledges that “Given the widespread application of BNG is still emerging, there is clearly further site-specific viability testing required of alternative BNG percentage requirements”. At present, the College cannot support a requirement in excess of 10%.
