Supplier Engagement Portal

    Collect Scope 3 supplier emissions data from hundreds of suppliers — without the spreadsheet chaos.

    What it does

    The Supplier Engagement Portal is the tool we built for clients who need real Scope 3 supplier data — typically NHS suppliers, manufacturers and any business answering a tender that asks about value-chain emissions.

    Upload your supplier list as a CSV, and the portal sends each supplier a branded link to a short emissions form. Responses flow back into your client dashboard in real time, with a clear status against every supplier (invited, opened, in progress, complete) so you always know where the gaps are.

    Reminder cadence, frequency and maximum chase count are all configurable per client, so suppliers stay engaged without feeling spammed.

    Who it's for

    • UK SMEs preparing a Carbon Reduction Plan with Scope 3 supplier data
    • NHS and PPN 06/21 suppliers needing verified upstream emissions
    • In-house sustainability leads chasing 50+ suppliers manually today

    How it works

    1

    Import your suppliers

    Upload a CSV of supplier names, contacts and spend. We validate the data and stage every invite for review before sending.

    2

    Suppliers self-serve

    Each supplier gets a branded link to a short, mobile-friendly form. No login, no PDF — just the data you need.

    3

    Track and chase

    Live status per supplier, configurable reminder cadence, and an aggregated view ready to feed straight into your Scope 3 calculation.
