Powerday launches free carbon reporting tool for construction waste

By Marcus Bennett

Powerday has launched a free Carbon Reporting Tool that calculates transport emissions for every waste movement leaving a contractor's site. The system draws data directly from Powerday's operational systems, then feeds live carbon figures into the reports contractors already file for clients and planners.

What the tool delivers

The platform issues a calculated carbon figure per project, derived from the loads collected and the routes driven. Each number traces back to a specific vehicle, a specific tonnage, and a specific date. For the first time, waste haulage becomes a line item in the carbon ledger rather than a quarterly estimate compiled from haulier invoices.

John O'Dwyer, Powerday's Associate Director – Environmental Sustainability, described the gap the tool fills: "Waste and logistics have long been one of the hardest parts of a construction project to put a real carbon number on."

The tool calculates emissions per movement, then aggregates them at project level. Contractors receive a number they can paste into existing carbon submissions without rebuilding their data infrastructure.

How it integrates

The tool does not require contractors to maintain a parallel dataset. Outputs land in the carbon reporting contractors already produce for planning conditions and client contracts. O'Dwyer said: "It plugs straight into the reporting they're already doing, so it's not extra work for anyone which is an extra bonus."

The integration matters because carbon teams at main contractors are not adding headcount. A new data feed that needs a separate spreadsheet gets ignored. One that lands inside the existing template gets used.

For prequalification questionnaires, the move shortens the path from bin to figure. The audit trail shifts from an invoice to a vehicle registration, a route, and a date. Tender submissions gain a specific number where they once carried a rounded estimate.

Why the pressure now

Planning conditions and client contracts now ask for evidence of carbon performance at every supply-chain node, including waste and logistics. Contractors that cannot share that data face a growing disadvantage on new tenders, according to Powerday. The procurement pinch has reached refuse haulage, not just materials and energy.

O'Dwyer added: "We also understand that contractors are under more pressure than ever to account for emissions across the whole supply chain, and transport forms an important part of that picture."

The shift is structural, not seasonal. Carbon clauses in planning consents and framework agreements now treat waste movements as reportable events, comparable to fuel use on site or embodied carbon in materials. Contractors who cannot evidence transport emissions are finding that point raised at tender clarification stage.

What comes next

The next development phase extends the tool to downstream Scope 3 emissions, the indirect carbon load generated once waste leaves for processing. O'Dwyer said: "We look forward to developing the tool further with our clients in mind." A fuller supply-chain footprint becomes possible, measured load by load and route by route over time.

The Scope 3 expansion will shift the tool from a transport calculator to a full waste-stream auditor. Downstream emissions include processing, transfer, and disposal, and they form the larger share of a load's total carbon. Covering them turns a transport number into a waste number.

Contractors running multi-site programmes will measure that rollout against their own reporting calendars. The next set of features will track the questions procurement teams raise during tender reviews, shaping the tool's development path over the coming year.
