Supply chain ESG
software

Invite every subcontractor and supplier to a short ESG questionnaire — no account needed on their side. Answers are scored automatically across Carbon, Waste and BNG, with a risk rating that flags exactly what's missing, replacing the Excel-and-forget cycle.

Everything a main contractor needs
to manage supply chain ESG

From sending the request to feeding the answer into your own carbon reporting.

No-account supplier questionnaires
Send a link, get an answer. Suppliers respond directly with no VerdCore sign-up required — removing the single biggest barrier to a fast reply.
Automatic Carbon, Waste & BNG scoring
Every response is scored the moment it's submitted — no manual review queue, no inconsistent scoring between whoever happens to read it.
Risk rating that flags specifics
Driven by whichever category scored weakest — a missing carbon figure, no accreditation on file, or an undeclared disposal route — not a vague overall number.
Same-day response tracking
See who's responded and who hasn't across a project's whole supply chain, instead of an inbox full of half-answered email threads.
Feeds your own Scope 3 reporting
Aggregated supplier carbon data becomes the Scope 3 evidence behind your own Carbon Reduction Plan and PAS 2080 report.
Alongside your own tracking
Supply chain scores sit alongside your own carbon, waste and BNG data — one coherent picture, not a separate supplier spreadsheet.

Replace the Excel-and-forget cycle

Everything you're already trying to chase by email, unified into one auditable system.

Three steps to scored
supplier ESG data

1
Invite your suppliers
Send a questionnaire link to every subcontractor and supplier on a project — no account needed on their end.
2
They answer directly
A short, structured questionnaire covering carbon, waste and BNG contribution — built for a same-day reply.
3
See scores & risk ratings
Every response scored automatically, feeding your own Scope 3 reporting the moment it lands.

Built around why the
request lands in the first place

Supply chain ESG requests exist because of what a main contractor has to report themselves.

PPN 06/21 Scope 3
The mandatory Scope 3 categories in a Carbon Reduction Plan depend on supply chain data.
PAS 2080
Collaborative carbon leadership across the supply chain is a core requirement of the standard.
ISO 14001
Accreditation and policy documents flow down the supply chain as part of the wider management system.
BNG contribution
Landscaping and habitat-related suppliers report how their work affects the site's overall biodiversity units.

The context behind the request

Why supply chain ESG requests exist, and how to respond well from the supplier side.

Frequently asked questions

What is supply chain ESG software?
It lets a main contractor send subcontractors and suppliers a short questionnaire covering carbon, waste and biodiversity data, then scores the answers automatically instead of a human reading each response and chasing gaps by email.
Do my suppliers need a VerdCore account to respond?
No. Suppliers are invited to a questionnaire link and answer it directly, with no VerdCore account or sign-up required on their side, so there's no barrier between sending the request and getting an answer back.
How are supplier ESG scores calculated?
Each questionnaire response is scored automatically across Carbon, Waste and Biodiversity Net Gain, with an overall score and a risk rating driven by whichever category the supplier scored weakest on, rather than a single blended number that can hide a specific gap.
Does this feed into my own PPN 06/21 Carbon Reduction Plan?
Yes. A Carbon Reduction Plan under PPN 06/21 requires Scope 3 data, which for most main contractors means data from their supply chain. Supplier ESG responses feed that same underlying dataset, rather than sitting in a separate spreadsheet disconnected from your own carbon reporting.
What's included in the risk rating?
The risk rating flags specific gaps rather than a generic score — a missing carbon figure, no accreditation on file, or an undeclared disposal route. That makes it clear what a supplier actually needs to fix, rather than leaving them guessing why they scored "high risk."
Is there a free plan?
Supply chain ESG questionnaires are part of VerdCore Business (£49/month). VerdCore itself is free to start with a 14-day Pro trial if you want to explore carbon, waste and BNG tracking before upgrading.
