A department store carries the environmental cost of its business model on every line of its accounts: hundreds of thousands of items sourced, a store estate to heat and light, and a delivery network built to move parcels quickly. It takes title to the goods it sells and holds the estate it trades from, so the emissions of the assortment and the emissions of the asset base both affect its own accounts rather than a supplier's or a concession partner's. Both therefore belong in the capital plan. Across the sector they are argued instead in the vocabulary of impact, materiality and disclosure — a language with no line in the accounts just described. IADS found the same during its Sustainability Operation Meetings in 2022 and 2023: the strategies were sound with reporting improving every year, and the case still had to be translated before a board would fund iti.  

The case has improved because two things happened: institutional investors converted a stated preference into an applied filter, and quantifying environmental exposure stopped being expensive. The obstacle was the cost of building a shared vocabularyii. This has now collapsed with the ability of large language models to read a company's disclosures against its financial statements, work that was once laborious but not conceptually hard. The IADS position is that sustainability should now be run as capital allocation, subject to the same tests as anything else, rather than as a communications function with a budget attached.
