The supplier emissions data template

What's inside

• 1 · Supplier & site

  Who the producer is, which production site the data covers, and the monitoring year — one workbook per site.

• 2 · Goods & emissions

  One row per product: commodity code and direct emissions intensity per tonne to 5 decimal places — the number the UK charge is built on.

• 3 · Precursors

  The covered input materials inside each product (crude steel in rolled goods, clinker in cement, ammonia in nitric acid) — charged as part of the final good.

• 4 · Verification

  Verifier, accreditation body and standards — because UK CBAM only accepts actual data that's been independently verified.

• Field guide

  Every field explained in one plain sentence with an example, so your supplier's plant engineer can fill it in without a consultant.

Why start now: your first UK return (due 31 May 2028) is built from data describing 2027 production — collected during 2027, then verified. And a return filed on default values can never be amended to real data later. The realistic lead time for getting usable numbers out of an overseas mill is months, so the asking starts now.
