# My buyer's supplier code says I must measure and reduce greenhouse gas emissions. What is the minimum to comply?

Canonical: https://senseible.earth/answers/supplier-code-of-conduct-ghg-clause-minimum

For a clause that says measure and reduce, the usual minimum is a yearly Scope 1 and 2 inventory made with the GHG Protocol, the bills and invoices behind it, and a written reduction goal or plan with actions you are taking. Read the exact wording first: words like report publicly, set targets or science-based raise the bar.

## Read the verbs in the clause

- Measure, track or monitor: an annual inventory of at least Scope 1 and 2.
- Reduce or improve: a goal or plan, and evidence of actions such as efficiency projects.
- Disclose or report: sharing figures with the buyer, through its portal or CDP, or publicly if the clause says so.
- Set targets, or science-based targets: a dated, numeric target; science-based means validated under SBTi criteria.
- Significant Scope 3: a screening of your own supply chain as well.

## The minimum pack for a measure and reduce clause

1. Scope 1: fuels burned on site and in owned vehicles, from fuel invoices.
2. Scope 2: grid electricity from discom bills, location-based with the CEA factor.
3. A one-page method note: boundary, period, factors and their sources.
4. A reduction goal, for example an absolute cut in Scope 1 and 2 by a stated year, and two or three actions with dates.
5. The source documents, kept for the audit period.

## When the minimum is not enough

If the buyer's code is the RBA Code, it asks for an absolute company-wide reduction goal and public reporting, which is more than this minimum. Buyers with their own science-based supplier engagement targets will also ask for a target, not just a plan. Ask the buyer which programme its clause supports.

## A decision rule

If the clause has no numbers, deliver the minimum pack this year and ask the buyer in writing whether it meets their expectation. If it names a standard, a date or a portal, meet that exactly.

## What Senseible does here

Senseible builds Scope 1 and 2 from your fuel invoices and electricity bills, with the factor and source on each line and the documents kept for a buyer audit. The figures are self-declared.
