Will fashion brands stop buying from mills that still burn coal in boilers?
Many will push you to stop, and some may move orders. Brands that signed the UN Fashion Industry Charter committed to phase coal out of their tier 1 and tier 2 suppliers' sites as soon as possible and by 2030 at the latest. It is a voluntary commitment, not law, so each brand's timing differs.
What the Charter commits brands to
- The Fashion Industry Charter for Climate Action, run under UN Climate Change, was renewed at COP26 in November 2021.
- Signatories commit to phase out coal at owned sites and at supplier sites, tier 1 and tier 2 for brands, as soon as possible and by 2030 at the latest.
- No new coal power at those sites from January 2023.
- Signatories also commit to give suppliers incentives to make the change. Ask what support your buyer offers.
Why processing mills are in the spotlight
Dyeing, printing and finishing need steam, and a coal boiler is often the largest emission source in a processing mill. These mills are usually tier 2 for a brand, and their boiler fuel sits in the brand's Scope 3 purchased goods. A coal phase-out promise cannot be met without changing your boiler.
What buyers are likely to ask for
- Monthly fuel use by type, with invoices.
- A dated plan for the boiler: fuel chosen, investment, and the year coal stops.
- After the switch, evidence that it happened, such as fuel bills and test certificates for biomass lots.
- Read your buyer's own climate transition plan, because the Charter sets the latest date, not each brand's date.
How to answer with a plan, not a promise
- Measure this year's coal tonnes and Scope 1 as the baseline.
- Compare PNG, biomass and electric options on cost per unit of useful heat.
- Pick a target year before 2030 and the finance route.
- Send the plan before the buyer asks; it is easier to keep orders with a dated plan than with a vague intention.
Worked example: how much of a mill's footprint is coal
- Coal: 6,000 t a year x 2.42 kg CO2 per kg = 14,520 t CO2
- Grid electricity: 30,00,000 kWh x 0.710 = 2,130 t CO2
- Coal share of Scope 1 and 2: 14,520 / (14,520 + 2,130) = 87%
Quantities are illustrative. The coal figure uses a flat IPCC-based factor; a GCV-based figure for lower grade coal would be lower.
What Senseible does here
Senseible shows boiler fuel Scope 1 from coal invoices month by month, so you can show a buyer the baseline and the fall after a switch. Its green loan readiness check helps prepare the finance file for a new boiler.
