Carbon management for
construction and infrastructure.

The public sector is mandating Carbon Reduction Plans for all suppliers. PAS 2080 is becoming a contractual requirement. Embodied carbon is under growing scrutiny. SBS delivers PPN 006-compliant reporting, PAS 2080 alignment and Scope 3 supply chain measurement built around the real operational challenges of construction and infrastructure businesses.

PPN 006 supply chain pressure
Public sector and NHS procurement requires a compliant Carbon Reduction Plan as a condition of contract award. Failure to comply means exclusion from public sector frameworks and tenders.
🧱
Embodied carbon and materials
Scope 3 Category 1 emissions from purchased materials — steel, concrete, timber — typically represent 60–80% of a construction project's total carbon footprint.
⚙️
Plant and fleet emissions
Construction plant, HGVs and site logistics generate significant Scope 1 emissions. Fleet electrification and fuel-switching pathways are increasingly expected by clients and regulators.

PAS 2080 alignment
Highways England, Network Rail and local authorities are increasingly requiring PAS 2080-aligned carbon management from their supply chains, including tier 2 and tier 3 suppliers.
Why sector expertise matters

Construction faces the most demanding carbon reporting requirements of any UK sector

No UK industry faces a more complex combination of mandatory reporting, contractual obligations and client-driven carbon requirements than construction and infrastructure. The government's PPN 006 mandate requires all suppliers with public sector contracts above £5 million to publish a compliant Carbon Reduction Plan. PAS 2080 is becoming embedded in Highways England, Network Rail and local authority procurement. And the drive to measure and reduce embodied carbon is accelerating across the built environment.

SBS works from a GHG Protocol and ISO 14064-1 aligned methodology, adapted to reflect the specific emission sources, project structures and supply chain dynamics of the construction sector. From plant and fleet Scope 1 emissions through to the Scope 3 embodied carbon in purchased materials, we build the complete picture your clients, procurement teams and regulators expect.

PPN 006
Mandatory for public sector suppliersAll suppliers bidding for central government and NHS contracts above £5 million must publish a compliant Carbon Reduction Plan evidencing Scope 1 and 2 emissions and a net-zero commitment by 2050.

Embodied carbon and Scope 3

Embodied carbon and supply chain are where it gets complicated

For construction businesses, Scope 3 emissions — particularly those embedded in purchased materials — are both the largest part of the carbon footprint and the hardest to measure. Steel, concrete, timber and aggregates each have complex, internationally sourced supply chains with highly variable carbon intensity depending on origin, manufacturing process and transport distance.

SBS applies ICE database and RICS methodology emission factors to your actual procurement data, producing project-level and organisational Scope 3 figures that stand up to client and regulatory scrutiny.

PPN 006 applies to contracts with central government and the NHS above £5 million per annum. However, many public sector clients — including local authorities, combined authorities and NHS trusts — are extending this requirement to contracts below the threshold through their own procurement questionnaires. If you tender for any significant public sector work, a compliant Carbon Reduction Plan is quickly becoming a prerequisite regardless of contract value.
Embodied carbon refers to the greenhouse gas emissions associated with construction materials and products across their lifecycle — from raw material extraction and manufacturing through to transport, installation and end of life. It is measured using material quantities from your bill of quantities or procurement records, multiplied by emission factors from databases such as the ICE Carbon Database or RICS Whole Life Carbon Assessment methodology. SBS applies these methods to produce project-level and organisational Scope 3 Category 1 data.
PPN 006 applies directly to your business if you hold a qualifying public sector contract above £5m. However, even if you sit below that threshold, principal contractors under PPN 006 obligations are increasingly required to gather supply chain carbon data from their subcontractors as part of their own Scope 3 Category 1 measurement. Being able to provide credible carbon data gives you a commercial advantage in supply chain selection.
PAS 2080 is the UK standard for managing carbon in infrastructure projects. It requires a carbon management plan covering the full project lifecycle, measurable carbon reduction targets, regular progress reporting, and engagement of the supply chain in carbon reduction. It applies across the value chain, not just to principal contractors. SBS supports businesses in developing PAS 2080-aligned carbon management approaches without the jargon.
A compliant PPN 006 Carbon Reduction Plan typically takes four to six weeks from initial data collection to a publishable document, depending on data availability and the complexity of your operations. The process covers Scope 1 and 2 measurement, a 2050 net-zero commitment, a reduction strategy with near-term milestones, and publication on your website. SBS manages the process end to end.
