Ecopilot search for supplier carbon data: How it works

Learn how Ecopilot finds public supplier carbon data, validates it and creates supplier-specific emission factors.

Written by Support

Ecopilot automatically searches for suppliers’ public carbon data and, when the data passes Greenly’s quality checks, creates a supplier-specific monetary emission factor (SEF). This factor estimates emissions per unit of spend with that supplier.

How to launch a search

  1. Go to Suppliers → Engage my suppliers and check that the suppliers are matched to the right companies.

  2. For one supplier, open the ⋯ menu and choose Launch Ecopilot search. For several, select the suppliers and use the same action in the bulk toolbar. Confirm the bulk launch when prompted.

  3. Follow the Ecopilot search column for progress and results. A search may take a few minutes.Access and limits: availability depends on the account and user permissions. If the action is unavailable or opens an access message, contact your AM or Greenly support. The documented interface limit is 50 suppliers per bulk launch, with a profile-level limit of 500 searches; remaining quota and eligibility can restrict a launch. A search may also be unavailable when one is already running, data has already been found, or a no-data search is less than one month old.Automatic launch: automatic search is launched for up to the top 50 highest-emitting suppliers of eligible NZC clients after supplier onboarding.

Where Ecopilot searches

Ecopilot searches the public web, including supplier websites and publicly accessible sustainability or GHG reports. It looks for a report from the supplier that contains greenhouse-gas information, prioritising the latest relevant report. If revenue is missing from the report, it also searches online for revenue.
Searches do not contact the supplier. A report behind a website restriction, or one that is not public, may not be found. For suppliers with little public reporting, requesting data directly through a supplier campaign can help.

How the factor is computed

Ecopilot reads the report and extracts Scope 1, Scope 2, and upstream Scope 3 emissions, plus revenue. When both Scope 2 methods are available, it prefers location-based data. For Scope 3, the calculation uses upstream categories 1–8, not downstream emissions.Monetary SEF = (Scope 1 + Scope 2 + upstream Scope 3 emissions) ÷ revenue.

The result expresses emissions per unit of currency spent. Ecopilot can compute a factor for each year with sufficient data in the report. This workflow is for monetary factors, not product or activity-based factors.

Quality checks: when is a factor created?

Ecopilot does not create a usable factor simply because it found a report. The documented automatic validation requires both of the following:

  1. Reliable, sufficiently detailed inputs. Ecopilot scores the quality of the GHG inventory and the revenue source on a scale of 0 to 1. It checks whether the inventory gives usable scope and upstream Scope 3 detail and whether the revenue source is trustworthy. The combined confidence score must be 1 out of 1 for automatic validation. Missing GHG data or revenue prevents automatic validation.

  2. A plausible sector comparison. Ecopilot compares the calculated factor with supplier factors in the same broad purchase category. It must fall between the 5th and 95th percentiles of that peer group. If there are too few comparable suppliers to build a benchmark, it is not automatically validated and should be manually reviewed.
    If both checks pass, Ecopilot can create a factor without a human review. If data is incomplete, unreliable, outside the benchmark, or lacks a sufficient benchmark, it is not automatically validated. The computation can be retained for review; an authorised Greenly reviewer can check the source, correct data, and approve it where appropriate. A failed benchmark is a flag for investigation, not proof that the supplier’s data is wrong.For CEs: use Suppliers → SEF validation (Admin) to inspect the data, source references, scores and reasons for non-validation. Verify the supplier, figures, reporting year and revenue against the source before approving; review notes may be visible to the client. Some review-screen labels and filters have had documented issues, so check the underlying values when in doubt.

What happens next?

  • Validated: a factor is available; the client can choose to apply it to transactions. It is not automatically applied.

  • Imprecise / not validated: data was found but did not pass the checks; a Greenly reviewer may investigate.

  • No data found: Ecopilot did not find usable data in this search. This does not prove no report exists; consider requesting data from the supplier.

  • In progress / not started: the search is running or has not yet been run.
    Results depend on public reporting: large suppliers are generally more likely to publish usable data. Early pilot figures came from small samples and should not be treated as a guaranteed success rate.
