What a label is, structurally
A claim on a pack is a statement by a seller about a system the buyer cannot inspect. It can be true, false, true-but-narrow, or literally meaningless, and nothing about its appearance distinguishes these. The useful classification is by what stands behind it: a third-party certification against a published standard with an audit; a first-party claim the seller makes about itself; a regulated term with a legal definition; or a marketing word with no definition at all. Almost all the information in a green claim is in which of those four it is, and almost none of it is in how the claim is worded. That is worth stating baldly because green wording is designed to be read the other way. A great deal of effort goes into making a first-party claim look like a certification, an aspiration look like an achievement, and a component claim look like a product claim. None of that requires anyone to lie. It requires only that a true, narrow statement be placed where a broader one would be expected, and that is a design decision made by people who understand exactly how it will be read.
Certification marks: what they establish
A third-party mark establishes that an auditor examined a defined system against a published standard and found it compliant at the time of audit. That is genuinely more than nothing: the standard is public, the criteria are specific, and there is a party other than the seller with something at stake. It is also narrower than it looks. It covers only what the standard covers, which is a defined subset — an environmental standard says nothing about pay, a price-based standard says nothing about pesticides. It is periodic and documentary. In some schemes and products, volume-tracking rules permit certified and uncertified material to be commingled provided the totals reconcile, so the mark may describe a volume rather than the leaf in the packet. Read a mark as naming a document you could go and read, because that is exactly what it is. Certification marks also differ in how demanding their entry level is, which a logo cannot convey. Some standards are designed as a floor that most competent operations can meet, on the theory that broad adoption raises a whole sector. Others are designed as a high bar that few reach. Both are legitimate designs and they mean very different things on a packet. A reader who wants to know which they are looking at has to go to the standard, which is public and which almost nobody reads.
Self-declared claims, and the specificity test
Most green wording on packs is first-party. It is not therefore false, but it is unverified, and the useful test is specificity. “Sustainably sourced” has no definition, no boundary and no measure: nothing would count as evidence against it. “All our tea is bought from suppliers audited annually against our published sourcing policy, which is at this address” is a claim that could be checked and could be wrong. The rule of thumb is that a claim which could not be falsified by any conceivable fact is not conveying information. Applied consistently, this dispatches most of the wording on most packs in the category, in a way that has nothing to do with whether the company behind it is behaving well. Two wording patterns are worth learning to spot. The first is the aspirational date: a commitment to achieve something by a year far enough away that nobody will check, made by people who will not be there. The second is the scope shift, where a claim about a company’s total volume is placed on a product that may not be part of it. Neither is false. Both convert a limited commitment into an impression of a general one, and both are extremely common.
Carbon claims and offsets
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
“Carbon neutral” on a product means that emissions attributed to it within a stated boundary have been calculated and matched by purchased credits. Three questions decide whether it means much. What boundary — the whole life cycle including the kettle, or the factory gate? What quality of credits, and are they avoidance or removal, permanent or reversible, and additional to what would have happened anyway? And what reduction has actually been made before offsetting, since offsetting an unchanged footprint and reducing one are very different achievements described by the same phrase. These questions are not obscure; they are the standard criticisms of offset-based claims across all product categories, and they have led regulators in several jurisdictions to scrutinise such wording more closely. For tea specifically there is an additional oddity. If the largest energy term in a cup is the kettle, as the footprint page argues, then a product-level carbon claim that stops at the shelf is excluding the biggest item — and a claim that includes it is making an assumption about how the buyer will behave. Neither boundary is wrong, and the choice between them changes the number substantially. A carbon claim on a box of tea is therefore unusually dependent on a decision the reader cannot see.
Packaging claims
Packaging is where the most confident and least reliable wording appears, and the packaging page covers the materials in detail. Three cautions carry over. A claim usually attaches to one component, not the pack — “plastic-free teabag” says nothing about the pouch the bags came in. “Compostable” without a named standard and named conditions is not a claim, and industrial compostability is not home compostability. And recyclability in principle is not collection in practice, which varies by municipality; a material described as recyclable may have no route where you live. The most trustworthy packaging labelling is the least confident-sounding: a component-by-component list saying which bin each part goes in. It is also worth noticing what packaging claims crowd out. A pack covered in material claims is telling you a great deal about the wrapper and nothing about the tea inside it — not where it came from, not when it was picked, not who grew it. Packaging is the part of the product a company controls completely and can change quickly, which makes it the easiest place to demonstrate effort. That is not a reason to dismiss the claims, but it is a reason to notice what is absent alongside them.
What to actually look for
Specificity over sentiment: a garden name, a scheme name, a standard version, a boundary, a date. Third-party audit over self-declaration, while remembering the audit’s scope. Consistency: a seller who says the same specific things year after year and answers a direct question with a direct answer. And silence: what a page or pack does not mention is often the most informative thing about it, because a seller who knows their supply chain well enough to describe the garden also knows who works in it. None of this makes a reader able to verify anything. It makes them able to tell the difference between a claim someone has made themselves accountable for and one they have not. That is a modest capability and it is the realistic one. No individual reader can verify a supply chain, and a framework that requires them to is not a framework. What they can do is notice the difference between a company that has written something checkable and one that has written something that could never be wrong — and, over time, notice which companies keep doing the first. Consistency across years is the closest thing to evidence available from outside, and it costs nothing to look for.
What this page does not claim
No brand, retailer, certification scheme or offset provider is named or evaluated. No claim is made that any particular kind of label is reliable or unreliable in practice; the page describes what each kind of claim can establish in principle. TeaHQ has not audited anything and cannot verify any seller’s statements, including those of sellers whose material this catalogue otherwise draws on. And nothing here says that any tea is sustainable, environmentally preferable or ethically produced — this catalogue takes the position that such a sentence has no truth conditions unless it names a boundary, a baseline and a measure. That position applies to this catalogue as much as to anyone else’s writing. TeaHQ has not inspected a tea field, audited a factory or measured anything described in these pages; the material here is compiled general knowledge about how these systems work, cited as such. It is useful for understanding what a claim means and useless for establishing whether any particular claim is true. Readers should hold it to the same standard it applies to a box of tea.
