Delivery Notes and Construction Carbon Returns

What you need to know

Start with the client’s reporting boundary, periods, materials and accepted calculation method.
National Highways lists delivery notes among possible source records; AMP8 requirements vary by water company.
Digital waste tracking requirements depend on role and nation. A missing weight is a gap to resolve, not a measured quantity.

Delivery quantities support carbon reporting as well as invoice checks. National Highways lists delivery notes among its possible source records, and AMP8 water-company requirements add another reason to keep material data usable. A ticket is an input to a carbon calculation, not a carbon return on its own.

On a Major Projects contract, it's working day 12 and the monthly carbon report is due. Someone in the project team has a spreadsheet open on one screen and a folder of scanned concrete delivery notes on the other. They're typing in batch volumes one by one. Some of the aggregate tickets have no weight on them, so they're working it back from the invoices. The asphalt tickets are still on site.

You capture the same delivery twice, once for the money and once for the carbon, and neither version is as good as it should be.

Start with the client’s reporting requirements

Agree the reporting boundary, period, required materials and calculation method before asking site to capture extra fields. Otherwise the same ticket may be processed several times without producing the data anyone needs.

National Highways Carbon Tool

National Highways’ Carbon Tool guidance calls for returns monthly or quarterly as instructed. Major Projects and specified Operations contracts report by working day 12; area-based reporting is coordinated quarterly. Confirm the arrangement for your contract. Source: National Highways Carbon Tool guidance, section 4.5.

The designated person keeps the supporting sources and provides a validation declaration. Delivery notes, invoices, waste records and EPDs are among the examples available for audit. Source: National Highways Carbon Tool guidance, sections 4.4–4.10.

Keep the load references so quantities can be traced from the return back to the source record.

Water: AMP8

AMP8 covers 2025–2030. Ofwat’s PR24 final commitment index lists company-specific capital or embodied-carbon commitments, including the four examples below. These are regulatory commitments for water companies, not a uniform delivery-ticket requirement for every contractor. Source: Ofwat PR24 commitment definitions.

Severn Trent: capital carbon. Check its current final definition and the project’s reporting brief; a carbon-reduction metric is not the same thing as a monthly delivered-quantity return.
Anglian Water: lower carbon concrete assets. Concrete and reinforcement records may support project calculations, but the current commitment definition and baseline must be checked before quoting the metric.
United Utilities: embodied greenhouse gas emissions. Confirm the current definition and the activity data required by the client rather than assuming every delivery-note field is mandatory.
South West Water: embodied greenhouse gas emissions. Confirm the current calculation method and any move from spend data to activity data in the client’s reporting instructions.

Do not carry a National Highways reporting timetable into a water contract. The client brief decides what is needed, how it is calculated and when it is due.

Why the ticket is the first place to look

The GHG Protocol offers supplier-specific, hybrid, average-data and spend-based methods for purchased goods and services. Physical quantities can be multiplied by a compatible emissions factor; spend-based calculations use monetary values. More specific data is not automatically more accurate: source quality and boundaries still matter. Source: GHG Protocol Category 1 guidance.

A ticket provides load-level quantity evidence. Match units to the emissions factor and reconcile rejected goods, returns and transfers according to the reporting method. Missing quantities need a documented source or estimate; do not silently replace them with guesses.

Qflow reported missing weight or volume information in 72% of key material deliveries in its dataset. It is vendor research, not a measured shortfall on National Highways or AMP8 jobs. Use it as a prompt to inspect your own records. Source: Qflow research announcement.

Prioritise the materials that drive your project’s emissions and the records most often missing. Concrete, asphalt and steel may be important, but use the project’s own carbon baseline rather than a historic network percentage as its ranking.

Digital waste tracking: check your role

The government’s updated timetable makes the service mandatory for permitted receiving-site operators in England and Wales from October 2026, with Northern Ireland and Scotland following in January 2027. The later phase for collectors is planned from October 2027. Check the applicable regulations and role rather than treating every contractor as covered at once. Source: GOV.UK digital waste tracking timetable.

A contractor can be a producer, carrier and receiving-site operator on different activities. Ordinary producers are not covered merely because they produce waste in the first phase; existing duty-of-care records still apply. Receiving-site permits and exemptions need separate checks.

The double-handling problem

On most infrastructure jobs the same delivery gets handled several times:

Site signs the ticket.
Someone sends it to the office for the goods received note (GRN) and invoice match.
The QS pulls the quantity for the cost report or a compensation event.
The sustainability lead pulls the quantity again for the carbon return.

Each pass is another chance to misread the ticket or record it differently. The QS and the sustainability lead can end up with different numbers for the same concrete pour, and skilled people spend working day 12 typing batch volumes.

Capture once, use twice

Capture the printed product specification: concrete mix designation, steel grade or aggregate type. If it is absent, flag the gap and request the supplier’s specification instead of inventing it. Record quantity, units and how it was checked; supplier; dispatch works or quarry where known; arrival date/time; unloading location; intended activity; and a clear ticket photo. “Dispatch works” means the production/loading location, not site Equipment. This is a recommended checklist, not a claim that Gather automatically populates each field.

Dispatch origin and transport mode/distance may be needed for transport emissions. National Highways asks for separate entries for material from different suppliers/manufacturers. Keep product identity and any EPD reference available too. Source: National Highways Carbon Tool guidance, FAQ 18.

One receiving record can serve both teams, but cost and carbon need not use identical final totals: returns, wastage, reporting periods and boundaries may differ. Agree how each team derives its figures from the shared source.

Practical steps before your next return

Map where each material's quantity comes from today. Ticket, invoice or estimate? Be honest.
Prioritise high-impact materials and missing quantity fields using your project’s baseline and reporting brief.
Ask suppliers for digital tickets and structured exports where available. Check access, units and corrections rather than assuming an emailed PDF removes data entry.
When a quantity is blank, request a reliable batch, weighbridge or supplier record. If estimation is permitted, label it, record the method and obtain the required approval. Keep an estimate distinct from a measured or supplier-declared quantity.
Agree a shared source record with the commercial team, then reconcile the different cost and carbon calculations. The materials delivery log template is a starting point.

Gather records delivery notes within the shift record, alongside the day’s work and resources. Its Record product page also describes photos with timestamps and GPS metadata. These records support a delivery history; they do not, by themselves, confirm the quantity received or prove that materials were used. See the Gather Record product page or book a demo.

FAQ

How often do National Highways carbon returns have to be submitted?

Monthly or quarterly as instructed. The guidance sets working day 12 deadlines for the relevant monthly and quarterly returns, including Major Projects and specified Operations contracts. Confirm your contract’s reporting route. Source: National Highways Carbon Tool guidance, section 4.5.

Do contractors have to use digital waste tracking from October 2026?

The first mandatory phase concerns permitted receiving-site operators in England and Wales, not every waste producer. A contractor operating such a site may be covered. Later phases and other UK nations have different timetables. Check your role and the current rules. Source: GOV.UK digital waste tracking timetable.

Can we report carbon from invoices instead of tickets?

Invoices can support a return if they carry the right quantity and product data. Spend-based calculations are a separate method, used where appropriate data is unavailable. Check the client’s accepted method and emissions-factor boundary. Source: GHG Protocol Category 1 guidance.

What is PAS 2080?

PAS 2080:2023 is BSI’s specification for carbon management in buildings and infrastructure. It concerns whole-life carbon management across the value chain, not simply scanning delivery tickets. Check which contractual certification or reporting requirements apply. Source: BSI PAS 2080 overview.
