Carbon accounting for construction. From tender to handover.
PAS 2080 requirements are flowing down from Tier 1 contractors. Construction companies need project-based emissions tracking, embodied carbon data, and compliant reporting.

The challenge
What construction are facing
PAS 2080 is flowing down the supply chain
National Highways, Network Rail, and major Tier 1 contractors now require PAS 2080 compliance from their supply chain. If you're a Tier 2 or 3 contractor, this lands on your desk whether you're ready or not.
Project-based reporting across multiple clients
Each client wants emissions data for their specific project, in their specific format. You might be running 20 projects across 5 clients, each with different reporting requirements. Spreadsheets don't scale.
Embodied carbon is complex
Calculating the carbon embedded in concrete, steel, timber, and other materials requires specific emission factors and methodology. Most construction firms don't have the technical knowledge to do this accurately.
Multiple reporting formats
One client wants a whole-life carbon assessment. Another wants a CRP for a government-funded project. A third wants Scope 1 & 2 operational data. You need a system that handles all of them from one data set.
PAS 2080 compliance is now required by National Highways, Network Rail, and major Tier 1 contractors — and those requirements flow down to every subcontractor in the chain.
The solution
How Climatise helps
Project-level emissions tracking
Track emissions per project, per site, per client. Roll up to company level for SECR, or drill down for individual project reports.
See this feature →PAS 2080 whole-life carbon
Calculate embodied carbon in materials and processes using PAS 2080 methodology. Generate whole-life carbon assessments that Tier 1 contractors accept.
Client-specific report templates
Generate reports in the format each client requires. PAS 2080, CRP, SECR — all from the same underlying data.
See this feature →Material-level carbon calculations
Emission factors for concrete, steel, asphalt, timber, and other construction materials built into the platform. No manual lookups.
Common questions
Construction carbon reporting FAQ
PAS 2080 is a standard for managing carbon in buildings and infrastructure. It provides a framework for whole-life carbon management, covering embodied carbon in materials, operational carbon during use, and end-of-life carbon. Major infrastructure clients like National Highways require it.
Increasingly, yes. Tier 1 contractors are flowing PAS 2080 requirements down their supply chain. If you're bidding for work on National Highways, Network Rail, or major construction programmes, you'll likely need to demonstrate PAS 2080 alignment.
Construction has uniquely high Scope 3 emissions from materials (embodied carbon). Concrete, steel, and asphalt carry significant carbon footprints. Construction firms also need project-level reporting rather than just company-level annual reporting.
Climatise can ingest waste data from any source and calculate the associated emissions. If you're using SmartWaste for waste tracking, that data can feed directly into your overall carbon calculations.
