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

Tools for LCA calculation in Norway – Life cycle assessment - KBCN1712

Some commonly used tools in Norway, such as vegLCA and NV-ghg, are observed to lack coverage of module C, which is required under criterion 7.3.1 for Life Cycle Assessment to achieve a higher level of performance beyond a Product LCA. If a project uses these tools, only a Product LCA can be achieved unless supplementary calculations addressing module C are included in the submitted evidence.

Using the CLIMB Model for Ecological Enhancement - KBCN1646

BREEAM Recognises CLIMB 1.2 Model as a means of complying with the requirements in BREEAM Infrastructure Issue 4.4 instead of the DEFRA Metric or BREEAM LUE calculator. The calculation you must do to get the percentage improvement in Biodiversity Net Gain from the CLIMB 1.2 model is as follows Percentage Improvement in Biodiversity Net Gain Legend

Notation	Term	Equation
A	Area in Hectares	-
NV	Factor for Natural Value	-
L	Factor for Landscape Value	-
S	Difficulty Factor	-
L	Factor for Time	-
I	Factor for Indirect Influence	-
T0	before influence/action	-
T1	after impact/action	-
U	Present value CLIMB units
V	Fabricated CLIMB units by creating biotopes
X	CLIMB units lost through deterioration of the biotope
Y	CLIMB units lost through indirect impact
Z	CLIMB units lost through indirect impact

The credit allocation is for BREEAM Infrastructure is as follows:

CLIMB Model 1.2 Percentage Improvement in Biodiversity Net Gain	BREEAM Infrastructure V6 Credits Awarded
Less than -25%	0
Between -24% and -6%	10
Between -5% and 4%	20
Between 5% and 9%	30
10% and above	40

Please provide the CLIMB Model tool and supporting documentation as evidence for your assessment. Please also note that CLIMB units for offsite enhancements are not recognised by BREEAM Infrastructure, therefore the above calculation should only consider onsite enhancement.
