The Language of Climate

Why Your Climate Commitments May Not Survive Scrutiny

The credibility test

In 1988, NASA scientist James Hansen testified before the U.S. Senate that global warming had begun. His testimony was precise, data-driven, and largely ignored by the business community.

Thirty-seven years later, the business community is producing its own testimony: net zero targets, sustainability disclosures, carbon reduction roadmaps, climate transition plans. And unlike Hansen’s testimony, most of it is neither precise nor data-driven. It is, forensically speaking, a liability waiting to be tested.

The problem with climate language

Climate documentation has a unique forensic profile. It is produced under pressure, regulatory, investor, public, by organisations that are often committing to outcomes they cannot yet guarantee, in language they have not examined carefully enough. The result is a category of documentation that is simultaneously high-stakes and forensically weak.

Trigger words: “net zero,” “carbon neutral,” “science-based,” “climate positive,” “committed to sustainability.” These terms now appear in virtually every major corporate communication. They have also become the primary targets of greenwashing litigation and regulatory investigation across the EU, UK, and US. The reason is forensic. Each term carries enormous implied commitment and almost no operational definition. A company that describes itself as “committed to net zero by 2050” without a credible pathway has made a statement that will be tested, in court if necessary, against what it actually did.

Structural ambiguity: “We will reduce our carbon footprint significantly over the coming years.” Significantly by what measure? Over how many years? Against which baseline? This sentence, representative of thousands in corporate sustainability reports, gives the appearance of commitment while avoiding it entirely. It is the grammatical equivalent of a firm handshake with no intention of following through. Regulators call it misleading. Forensically, it is a structural void.

Passive voice as deflection: “Emissions reductions were slower than anticipated.” “Targets were not met in the reporting period.” “Challenges were encountered in the transition to renewable energy.” These constructions, common in climate progress reports, are designed to describe failure without owning it. They use grammar to dissolve accountability into abstraction. In an investor briefing or regulatory submission, they are red flags. In litigation, they are evidence.

What language forensics finds in climate documents

Climate failures do not arrive as missed targets. They arrive as credibility collapses, moments when the language an organisation used to describe its commitments is held against what it actually delivered.

When I examine climate documentation, net zero strategies, sustainability disclosures, transition plans, investor communications, public statements, I look for the architecture of accountability. Where has the organisation made specific, verifiable commitments, and where has it retreated into language that sounds committed but proves nothing?

A net zero target with a 2050 date but no 2030 milestone. A transition plan that describes renewable energy adoption as a priority but allocates no budget to it. A sustainability report that uses “progress” without defining what progress was measured against. A climate disclosure that uses “material risks” without quantifying them. Each of these is a forensic finding. Each is a gap that a regulator, investor, or activist will close, on their terms, not the organisation’s.

Who this matters for

Organisations producing climate disclosures for mandatory regulatory frameworks. Businesses making public net zero commitments that will be tested against operational decisions. Leadership teams whose climate language is reviewed by investors applying ESG criteria. Any organisation where the gap between climate promise and climate delivery carries legal, regulatory, or reputational consequence.

Climate strategy is your credibility test. If the language behind that strategy has not been read forensically, you do not know what you have committed to, or what you have exposed yourself to.

The window is narrowing

Climate language regulation is accelerating. The EU Green Claims Directive, the SEC climate disclosure rules, the UK’s FCA sustainability rules, each of these frameworks is designed to test the language of climate commitments against operational reality. Organisations that built their climate credibility on well-intentioned but forensically weak language are discovering that good intentions are not a defence.

A forensic review of your climate documentation now costs a fraction of what imprecise language costs in a greenwashing investigation, or a missed net zero target that was never realistically defined in the first place.
