Carbon, waste, water, biodiversity, inspections and supplier ESG — recorded on site, calculated on DEFRA factors, and issued as the documents a client, framework or planning authority actually asks for.
Compliance duties sit with the principal contractor. Software produces the evidence and does the arithmetic — it does not discharge the duty, and none can.
Very little of this is one statutory duty. Most of it is contractual — a client, a framework or a planning condition asking you to prove something. Each area below has its own page.
Biodiversity net gain has a free calculator on Defra’s Statutory Biodiversity Metric v1.0.4 — no sign-up needed.
Emission factors are transcribed from the DESNZ/Defra full conversion factor workbook, read from the source sheets rather than from a third-party summary.
Read the full method — six errors and what caused each →Stated here rather than discovered later. Where a figure cannot be sourced properly, none is invented.
Free for two sites, no card. Paid plans add unlimited sites, your logo on the PDFs, and other people on the account.
In practice it is whatever a client, framework or planning authority asks you to evidence: carbon under PAS 2080 or PPN 06/21, waste transfer and consignment notes, water use and discharge consents, biodiversity net gain where planning requires it, and the inspection and incident records behind an environmental management plan. Very little of it is a single statutory duty; most of it is contractual.
No. The duties sit with the principal contractor and the company, and no software discharges them. What software does is produce the records that evidence them, on the right emission factors, in the format the client asks for.
The DESNZ/Defra greenhouse gas conversion factors, published annually. The set that applies is the one current for the date of the activity, not the date you run the report — otherwise a figure you have already submitted in a SECR or PPN 06/21 return changes when a new workbook is published.
In England, yes, for most developments requiring planning permission — a condition under the Environment Act 2021, in force from 12 February 2024 for major developments and 2 April 2024 for small sites, with exemptions. It does not apply in Scotland, Wales or Northern Ireland.
Not by law in England — the SWMP Regulations were repealed in 2013. They are still written into contracts and framework requirements, so the figures are commonly asked for even though the statutory duty has gone. Your duty of care for waste is separate and still applies.
Add a site, log a week of fuel and waste, and generate the report. If it is not the document your client asked for, you will know inside an hour and you will have spent nothing.
We are taking on a small number of sites while the tool settles. If you want input into what gets built next, now is the time to be on it.
