Biodiversity Net Gain – Sites with a zero baseline - KBCN1884

When assessing a site with no ecological features, pre-development, the "BREEAM-CEEQUAL-HQM-Change-in-Ecological-Value-Calculator" tool available in BREEAM Projects, can be used to calculate the percentage biodiversity net gain from a zero baseline. This method caps the percentage biodiversity net gain, so the maximum number of credits that can be achieved using this approach is as follows:

• BREEAM UK New Construction 2018/V6 = 3 credits
• BREEAM UK New Construction Residential V6.1 / Home Quality Mark = 6 Credits
• BREEAM Infrastructure V6 = 30 Credits

The cap on percentage biodiversity net gain seeks to ensure comparability between assessments, as it may be easier to achieve a high score from a zero baseline.

PAS 2080:2023 – BREEAM Infrastructure - KBCN1628

An updated version of PAS 2080 was released in April 2023 (PAS 2080:2023), superseding the previous version (PAS 2080:2016). The latest version of PAS 2080 may be used in BREEAM Infrastructure assessments in place of the previous version. The equivalent, relevant clauses are given in the table below.

PAS 2080:2016 (original)	PAS 2080:2023 (updated)
Clause 7 – Quantification of GHG emissions	Clause 7 – Whole life carbon assessment principles to support decision-making
Clause 8 – Target setting, baseline setting and monitoring	Clause 8 – Target setting and baselines
Clause 9 – Reporting	Clause 9 – Monitoring and reporting
Clause 10 – Continual improvement	Clause 11 – Continual improvement
Clause 12 – Claims of conformity	Clause 12 – Claims of conformity

The references to specific clause numbers for claims of conformity remain unchanged (part of Clause 12 in PAS 2080). The latest version of PAS 2080:2023 is available to download from BSI: https://knowledge.bsigroup.com/products/carbon-management-in-buildings-and-infrastructure An updated guidance document for PAS 2080:2023 is available from ICE: https://www.ice.org.uk/engineering-resources/briefing-sheets/guidance-document-pas2080
