ESG Communications: Why Vague Sustainability Claims Are Becoming a Liability

The Gap Between ESG Claims and ESG Substance

There is a widening gap in the market between organisations that are genuinely integrating environmental, social, and governance considerations into their strategy — and organisations that are communicating as if they are. This gap is not invisible. It is being measured by investors, scrutinised by regulators, and increasingly surfaced by investigative journalism and NGO campaigning.

The organisations most at risk are not necessarily those with poor ESG performance. They are the ones whose communications outpace their substance — those whose language implies more than their actions deliver.

What Greenwashing Looks Like in Practice

Greenwashing is not always deliberate. In many cases, organisations genuinely believe their ESG communications are accurate. The problem is that communications teams are often operating at a remove from the operational and procurement realities of the business, producing language that is technically defensible but practically misleading.

Common patterns include:

Absolute claims based on partial scope: "We are committed to net zero" without specifying which emissions scope, which year, or which operations are included.

Inputs presented as outcomes: "We invested £X million in sustainability initiatives" without stating what those initiatives achieved.

Process presented as progress: "We have a robust sustainability committee" without disclosing what that committee has actually decided or changed.

Comparisons without baselines: "We reduced emissions by 30%" without stating what year the comparison is made from or whether the baseline has been restated.

The Regulatory Direction of Travel

Across major markets, regulators are moving toward mandatory, standardised ESG disclosure requirements. The EU's Corporate Sustainability Reporting Directive, the SEC's proposed climate disclosure rules, and the IFRS Sustainability Disclosure Standards all move in the same direction: away from voluntary, narrative ESG communication and toward auditable, comparable, structured reporting.

Organisations that have been relying on loosely worded sustainability language will find this environment increasingly inhospitable. The question is not whether stricter standards are coming — it is whether your communications are ahead of them or behind them.

What Credible ESG Communications Look Like

Credible ESG communication is not modest communication. It can be ambitious, even aspirational. But it is grounded in specifics:

• Scope and boundary: what is included and excluded in any claim
• Baseline and trajectory: where you started, where you are, and where you are going
• Verified data: third-party assurance or alignment with recognised reporting standards
• Material topics: focus on the ESG issues that are actually material to your business, not a broad catalogue of every initiative that casts you in a positive light

The organisations that build lasting reputational advantage through ESG are the ones that treat it as a strategic discipline rather than a communications exercise — and whose external communications reflect that discipline accurately.

The Reputational Calculus

The short-term reputational benefit of expansive ESG claims is real. But so is the long-term reputational risk when those claims are tested. A single well-documented NGO report, an investigative article, or a regulatory inquiry can undo years of carefully managed ESG narrative in days.

The most defensible ESG communications position is simple: say what you are doing, show how you know it is working, and be honest about where you have more to do.
