Reading a sustainability claim
Every claim is certified, measured or asserted, and only the first two go out.
The dilemma
The client wants a "sustainability statement" for the brochure by tonight. A language model writes one in ten seconds: eco-conscious, net-zero ready, locally sourced, passive design principles, green-certified materials. It reads beautifully. None of it is false, exactly, because none of it says anything you could check. Do you send it?
The choices
Send it; the client wanted words. Or strike every adjective and keep only what can be pointed at: a GRIHA or IGBC rating applied for, and at what level; an EPD for a named product; a simulated energy figure with its method; the brick kiln's distance in kilometres. Or the honest middle: send the checkable list, and say plainly which claims the project cannot yet make.
The consequence
Send the fluent version and you have made a public claim you cannot defend. In India, since October 2024, an environmental claim you cannot substantiate is a consumer-law matter under the Central Consumer Protection Authority's greenwashing guidelines — "sustainable", "eco-friendly" and "carbon-neutral" are named there as words that need qualifiers and evidence — and the UK's regulator says the same. Send the checkable version and the statement gets shorter and plainer, and every line of it survives a question. The model did nothing wrong. It produced what a "sustainability statement" usually looks like. Deciding what may be claimed was never part of its training.
The case
A fourth-year studio writes the environmental page of a competition entry. One team asks a model and pastes the result: "harnesses passive cooling, sustainably sourced timber, net-zero aspiration." The tutor reads it aloud and after each phrase asks, "show me." Passive cooling — which move, and what does the simulation say? Timber — which species, which certificate? Net zero — measured how? The second team's page has three lines and two numbers, and a sentence that says no rating has been applied for. It is the only page in the room that could be shown to a regulator.
Try it
Ask a model for a 100-word sustainability statement for any project you know. Underline every adjective. For each, write the document that would substantiate it, or "none." Rewrite the statement using only the lines with a document. Compare the lengths.
Take it to crit
Read the student's environmental statement and, at each adjective, ask for the document behind it. Count how many survive. Then ask whether they can say, in their own words, the difference between what is legal to claim, what is ethical to claim and what merely sells — and which of the three the model was optimising for.
How it works
A language model produces the likeliest sentences for the phrase "sustainability statement," and the likeliest sentences are marketing, because most such statements in its training data were marketing. The fluency-borrows-authority card explains why this reads as authority. The defence is a sorting rule, not a better writing style. Sort every claim into certified (GRIHA, India's national rating system, developed by TERI and adopted by the Government of India in 2007; IGBC, the Confederation of Indian Industry's rating body; LEED), measured (a figure with a method and a date) or asserted (an adjective). Only the first two go out — and a certification certifies what it assessed, at the level it assessed it; a GRIHA rating on the building does not make every other sentence on the page true. The Indian rule comes first. The Central Consumer Protection Authority's Guidelines for Prevention and Regulation of Greenwashing or Misleading Environmental Claims, notified on 15 October 2024, define greenwashing to include vague, exaggerated or unsubstantiated claims and the hiding of harmful attributes, and say that generic words — clean, green, eco-friendly, sustainable, carbon-neutral, natural — may not be used without qualifiers, substantiation and disclosure; the Advertising Standards Council of India's guidelines on environmental claims sit beside them. The UK's Competition and Markets Authority published a Green Claims Code in 2021 with six principles — claims must be truthful and accurate; clear and unambiguous; must not omit or hide important relevant information; comparisons must be fair and meaningful; claims must consider the full life cycle; claims must be substantiated — and it is a useful checklist anywhere, because it asks of each sentence exactly what a juror asks. Legal, ethical and marketed are three different tests. A sentence can pass the third and fail the first two.
