What General ESG Marks Actually Do

General ESG marks have always been about one thing: signalling that a business is, on the whole, trustworthy and responsible. They don’t check individual claims. They vouch for the business as a whole.

B Corp is the clearest example, alongside marks like 1% for the Planet, which signals an ongoing environmental commitment rather than verifying any one claim, and the UN Global Compact, a membership pledge to a set of principles that’s largely self-reported rather than independently checked claim by claim.

Before comms could be verified directly, that mattered. If a stakeholder couldn’t check a specific claim, the mark was the next best thing: proof that someone, somewhere, had assessed the business and found it credible.

Stakeholders extended that credibility to whatever the business said afterwards.

What’s Changing

That’s changing. Services like truMRK verify comms directly, at the point they’re published, rather than vouching for a business in general. If a specific claim can be checked, stakeholders no longer need to infer trust from a general mark. They can check the claim itself.

truMRK checks a report or piece of communications from three angles.

First, substantiation: are the claims made within it backed by evidence, and ideally, has that evidence been verified by a reputable third party, rather than resting solely on the organisation’s own reporting.

Second, regulatory language alignment: checking the wording used throughout against the standards relevant to the business’s markets, such as the CMA’s Green Claims Code or the ASA’s CAP guidance in the UK.

Third, context: confirming the content isn’t misleading by omission, that no contextual or material fact has been left out which, if included, would change how a reader interprets it.

Only once a piece of communications clears all three does it count as verified.

The Real Cost of Earning a Mark

Earning a mark like B Corp isn’t quick or cheap. It takes months: gathering documentation, coordinating people across departments, submitting evidence, waiting on review. B Lab’s standards, currently being overhauled through 2026, are becoming more demanding, not less.

All of that effort goes into a single overall verdict about the business. None of it verifies whether any specific claim made afterwards is true, correctly worded, or fairly framed.

So there’s a real choice available now. A business can keep spending that time, money, and energy earning a general mark. Or it can have its comms verified through a process like truMRK’s, and put that time, money, and energy back into the work the mark was always meant to reflect: actually improving the business.

Where This Doesn’t Apply

This doesn’t apply to every certification. Some marks aren’t reputational at all, they measure something specific that comms verification can’t replace: a measured environmental outcome, a scientifically validated target, an audited fact about how or where something was made.

None of these are made redundant by truMRK, if anything, they matter more, since a claim needs solid data behind it before substantiation, wording, or context can even be checked.

The distinction that matters, then, is simple: does the mark tell stakeholders “trust this business in general,” or does it verify a specific fact a claim can’t verify on its own? Only the first is displaced by direct comms verification.

Regulation Is Pushing the Same Way

The EU’s Empowering Consumers for the Green Transition Directive, applying from September 2026, bans vague environmental claims unless they’re backed by evidence.

The requirement isn’t to hold a general mark of good character, it’s to be able to prove what was actually said, in the right terms, with the full picture attached.

That’s exactly the ground truMRK’s process is built to cover.

A Reallocation, Not a Retreat

A distinct professional archetype is emerging within modern organisations. This is not simply the boldest voice in the room, nor the most cautious. It is the individual capable of holding both instincts at once: part storyteller, part translator, part risk-literate strategist.

The responsible communicator operates at the intersection of marketing, legal, ESG and executive leadership, with a singular mandate: ensuring that what an organisation says about itself can withstand scrutiny of what it actually does.

This role has emerged out of necessity rather than design. A decade of greenwashing controversies, tightening regulation, and increasingly sophisticated public and investor scrutiny has established a new operating reality: communication is no longer a downstream function that follows the substantive work of the business. It has become integral to that work.

Where communication fails to hold up under scrutiny, the resulting reputational, financial and legal consequences can significantly outweigh whatever commercial benefit the original message was designed to deliver.

Recognising and empowering the responsible communicator matters because their absence carries a measurable cost. Where no one in the process is asking whether a claim can genuinely be substantiated, organisations drift toward language that performs well internally but fails to withstand external examination. The responsible communicator is the individual who raises that question at the outset of the process, rather than the legal function that raises it only once the campaign is already committed.

Trust as a Strategic Asset, and Why Sustainability Communication Is Where It Is Won or Lost

Trust has traditionally been regarded as a soft, values-driven consideration, acknowledged in principle but rarely prioritised against commercial metrics. That position is no longer tenable. Trust is now demonstrably linked to the outcomes that matter most to any organisation: customer retention, investor confidence, employee advocacy and, ultimately, licence to operate.

Few domains illustrate this more clearly than sustainability communication, where the distance between claim and substantiated reality is more visible, more scrutinised, and more consequential than almost anywhere else in corporate communication.

Sustainability is the domain in which this gap is most exposed. Regulatory definitions around environmental claims are tightening considerably. Investors, NGOs and independent researchers are verifying claims in near real time. Consumers, particularly within younger demographics, increasingly interpret unsubstantiated environmental claims as an indicator of broader institutional bad faith, one that extends well beyond the specific claim in question.

This is precisely why sustainability communication, executed with rigour, represents one of the most effective mechanisms for building organisational trust.

Claims that are precise, evidenced and appropriately qualified do more than mitigate reputational risk. They signal a level of institutional discipline that lends credibility to the organisation’s broader communications.

Sustainability communication should therefore be understood not as a risk to be managed downward, but as one of the clearest available opportunities to build durable trust.

Where truMRK Fits: Converting Risk Management Into Strategic Advantage

Every organisation navigates an inherent structural tension. Legal and risk functions are mandated to identify vulnerability in every claim. ESG functions are mandated to ensure that claims genuinely reflect underlying performance. Creative functions are mandated to produce work that resonates with an audience. Left unmanaged, these three mandates pull in different directions, and the usual casualty is either the ambition of the message or the speed at which it reaches market.

Campaigns are frequently diluted into safe but forgettable language, or, in the alternative, released with claims that have not been adequately tested.

truMRK is designed to resolve this tension at its source, rather than adjudicate between competing functions after the fact.

For legal and risk teams

truMRK provides something rarely available within existing creative workflows: a verifiable, auditable record confirming that every sustainability claim has been checked against underlying evidence before it reaches any external audience. This distinction is material. It is the difference between a claim that can be confidently defended before a regulator and one that becomes the subject of a greenwashing investigation.

Risk functions are repositioned from a late-stage gatekeeping role to an early, structural safeguard, because the necessary verification has already taken place upstream.

For ESG teams

truMRK closes the gap between the data they hold and the narrative that marketing intends to communicate. It provides a mechanism to validate, on an ongoing basis, that public claims remain aligned with actual performance as standards, disclosure requirements and underlying data evolve.

As a result, the ESG function is repositioned from a perceived constraint on communications to the enabling structure that makes ambitious claims possible in the first place.

For creative teams

This is where the greatest value is realised. When verification has already taken place, when a claim has been evidenced and tested before it reaches a creative brief, creative teams are free to focus on their core function: producing work that genuinely engages an audience. Campaigns are no longer diluted into vague, risk-averse language out of institutional caution, and strong creative concepts are no longer abandoned late in the process due to unresolved substantiation concerns. The risk assessment occurs prior to the creative process, rather than in competition with it.

This is the underlying value of addressing risk at its source. It does more than protect an organisation from exposure. It creates the conditions under which the individuals responsible for building brand affinity are able to do so with genuine confidence.

The Opportunity Ahead

The organisations that will lead the next decade of sustainability communication will not necessarily be those making the boldest claims. They will be those making the most credible ones, communicated by professionals equipped to do so with confidence, and underpinned by systems that have already established the evidence base required to support them.

The responsible communicator, supported by infrastructure such as truMRK, should not be regarded as a constraint on organisational ambition.

Rather, they represent the mechanism by which that ambition becomes sustainable in practice.

Trust has become one of the defining commercial challenges of the decade. For organisations that communicate on sustainability, environmental impact or ethical conduct, the cost of a single unsubstantiated claim has risen sharply, while the tools available to interrogate those claims, whether regulatory, journalistic or technological, have multiplied.

The evidence of a changed landscape is clear. Edelman’s 2026 Trust Barometer records a broad decline in institutional trust and a retreat into narrower circles of confidence. In the United Kingdom, the Competition and Markets Authority can now impose fines of up to 10% of global turnover for misleading environmental claims under the Digital Markets, Competition and Consumers Act 2024, and has identified greenwashing as an enforcement priority. The Advertising Standards Authority continues to uphold rulings against environmental claims at a steady rate, including high-profile decisions against fashion and travel brands throughout 2025. In the European Union, the Empowering Consumers for the Green Transition Directive takes effect on 27 September 2026, prohibiting generic environmental claims and unsupported “climate neutral” product labels. In the United States, the Federal Trade Commission’s review of its Green Guides remains ongoing.

Against this backdrop, the question facing chief executives, marketing directors and sustainability leads is no longer whether trust requires active management.

It is how to establish credibility at a time when unsubstantiated claims carry material legal, financial and reputational risk.

Four signals are likely to distinguish credible organisations from the rest in 2026:

1. Specificity

General claims are increasingly indefensible. Descriptors such as “greenest”, “leading” or “industry-first” cannot withstand regulatory or journalistic scrutiny, and their continued use is, in itself, a signal of weak substantiation. Credible reporting replaces such language with defined metrics, clear baselines and recognised assurance standards. A statement such as “a 34% reduction in Scope 1 emissions since 2019, verified to ISAE 3410” is specific, measurable and defensible in a way that no superlative can be. The organisations being believed in 2026 have substituted adjectives for data.

2. Independent verification

Claims reviewed only by the organisation that made them carry limited weight. The terms that increasingly matter to regulators, investors and informed consumers are third-party, independent and pre-publication, each of which implies that a party without a commercial stake in the outcome has examined the claim in question. Self-declaration, once sufficient, is now regarded with suspicion. truMRK’s approach, and the principle underpinning the Anti-Greenwash Charter which truMRK supports, is built on this premise.

3. Transparency about weaknesses

Reports that present only positive outcomes are increasingly read as incomplete, and in some cases as misleading. Sophisticated stakeholders, including investors, regulators, journalists and NGOs, have learned to distinguish polished reporting from honest reporting. The credible sustainability report of 2026 identifies areas of regression, acknowledges missed targets, and describes the remedial actions being taken. Omitting such information no longer conveys strength; it suggests the opposite.

4. Traceability

The credibility of a claim depends on the accessibility of the evidence supporting it. This means clear references to underlying data, transparent notes on methodology, and an auditable chain between headline figures and the calculations beneath them. Where a reader is required to accept an assertion on trust alone, that trust is increasingly unlikely to be granted.

The cost of inadequate substantiation

The consequences of publishing poorly substantiated claims extend well beyond public criticism. Retraction is expensive, both in direct costs and in lost management time. Regulatory penalties under the DMCC Act, the Empowering Consumers Directive and equivalent regimes can be substantial. The less visible costs, such as client attrition, lost tenders, reduced investor confidence and diminished ability to attract talent, are more difficult to quantify but often more material. Organisations that invest in independent pre-publication review in 2026 are likely to regard it, in retrospect, as disproportionately high value for the cost incurred.

A discipline, not a campaign

An effective trust strategy is not a communications exercise. It is a discipline, supported by governance, applied consistently, and capable of withstanding external examination. It requires claims that can be defended, evidence that can be produced on request, and a willingness to invite scrutiny rather than resist it. It also requires a tolerance for publishing findings that are not uniformly favourable.

This is the principle on which truMRK operates. Every organisation that commissions a review receives a Transparency Report and a corresponding score: an independent assessment of the strengths, weaknesses and areas of risk in its sustainability reporting, prepared to the same standard regardless of the outcome. The decision to act on the findings is the organisation’s alone. The Transparency Report can be used privately to inform internal improvement. Alternatively, the organisation can publish the report alongside the original content and append the truMRK badge as a visible indication that the reporting has been independently reviewed.

The second option represents the stronger trust signal. An organisation that publishes its review in full, including findings that identify limitations or areas for improvement, provides stakeholders with something that no communications exercise can replicate: the means to verify. In the current environment, that capacity to be checked is among the most valuable signals an organisation can offer. A published example is available here.

Trust, in 2026, is not established through assertion. It is established through evidence that others are permitted to examine. The organisations that recognise this distinction, and act on it, will be the ones credited with credibility by the audiences that matter.

In boardrooms and communications teams alike, trust has become both a strategic priority and a reputational vulnerability. Over the past 12 months, a series of major global studies has reinforced a consistent conclusion.

Business remains comparatively trusted, yet that trust is conditional, fragile and increasingly dependent on evidence.

For organisations communicating sustainability commitments, the message is direct. Assertions alone are no longer sufficient. Scrutiny is intensifying, and stakeholders are differentiating sharply between credible disclosure and reputational positioning.

Below is a synthesis of the most significant corporate trust research published in the past year and the implications for responsible sustainability communications.

Business Retains a Lead but Confidence Is Narrow

The 2025 edition of the Edelman Trust Barometer, surveying more than 30,000 respondents across 28 markets, reports that business remains the most trusted institution globally, ahead of government and media.

Business recorded an average trust score of approximately 62 percent, compared with 52 percent for government and 50 percent for media. In the United Kingdom, business trust levels hover only slightly above the 50 percent mark.

However, the headline conceals a more complex reality.

Richard Edelman, CEO of Edelman, described the current environment as a “cycle of distrust fuelled by grievance,” pointing to economic anxiety and perceived inequality as key drivers of scepticism. Trust in business may be comparatively higher, but it is neither unconditional nor secure.

Leadership Credibility Is a Critical Weakness

More striking than institutional trust levels is the widening gap between trust in companies and trust in their leaders.

More recent findings from the Edelman research show that roughly two thirds of respondents globally express distrust in business leaders.

A substantial proportion believe executives may mislead stakeholders, particularly when communicating on societal or environmental issues.

This distinction is material. Stakeholders are increasingly separating an organisation’s stated purpose from the perceived sincerity of its leadership. For sustainability communications, this creates a clear exposure. A technically accurate claim delivered without clarity, proportionality or supporting evidence may still be interpreted as opportunistic.

Consumers Are Quicker to Withdraw Trust

Research from Forrester reinforces the behavioural shift underway. Trust, once eroded, is less likely to recover quickly. Forrester’s 2025 consumer research across multiple global markets identifies declining trust across established institutions, technology firms and digital platforms.

The firm cautions that weak governance around emerging technologies, particularly artificial intelligence, could accelerate this trend. Its forward looking analysis suggests that a significant proportion of brands risk eroding customer trust through poorly implemented automation and AI driven services.

The broader signal is structural. Trust is increasingly tied to governance, oversight and demonstrable responsibility, rather than brand equity alone.

Artificial Intelligence and the Governance Imperative

A major global study conducted by KPMG in partnership with the University of Melbourne surveyed more than 48,000 individuals across 47 countries to assess public attitudes toward artificial intelligence.

Among the findings:

• 58 percent of respondents report intentionally using AI tools

• Trust in AI systems has declined in several advanced economies

• Concern about misuse, inaccuracy and lack of oversight has increased

• Trust levels are significantly higher in emerging markets than in advanced economies

KPMG emphasised in its accompanying commentary that trust must be designed and governed, not assumed.

The relevance to sustainability communications is clear.

Claims supported by complex data, modelling or AI assisted analysis will face heightened scrutiny unless accompanied by transparent methodology and accessible explanation.

The Commercial Value of Trust

Beyond perception, trust is increasingly linked to measurable commercial outcomes.

Analysis published by the Institute of Practitioners in Advertising in partnership with the Financial Times highlights a consistent relationship between trusted brands and long term business performance, including resilience during periods of volatility.

Trust functions as a form of risk mitigation. It supports customer retention, strengthens brand preference and provides reputational protection during periods of challenge.

Conversely, unsubstantiated or exaggerated claims introduce regulatory, legal and investor risk. In the United Kingdom, scrutiny from regulators and evolving advertising standards reinforce the expectation that claims must be clear, specific and supported by evidence.

Implications for Sustainability Communications

Across these research streams, several conclusions emerge.

First, trust is conditional. Business retains a relative advantage, yet public confidence is limited and reversible.

Second, evidence is central. Stakeholders increasingly expect accessible substantiation, not aspirational language.

Third, governance shapes credibility. The process by which claims are developed, reviewed and disclosed is now part of the trust equation.

Fourth, transparency reduces risk. Independent assessment, documented evidence and public disclosure frameworks materially strengthen confidence.

There is a simple idea at the heart of truMRK.

Most sustainability communication today is shaped by risk management. Organisations aim to stay within regulatory guidance and avoid accusations of greenwashing. The result is often a lowest common denominator approach. Claims are softened. Language is cautious. Disclosure is selective.

truMRK is built on a different premise.

It is not about doing just enough to avoid being challenged. It is about raising the bar so that evidence, clarity and context become visible standards of responsible communication.

If organisations know their sustainability communications will be reviewed across claims, language and context, they are more likely to publish information that is clear, evidenced and transparent.

And when that expectation becomes visible across a sector, collective standards will begin to rise.

1. Giving Credible Organisations a Clear Signal of Trust

Some organisations are already working hard to communicate responsibly.

When their draft communications are reviewed by truMRK, they will score strongly across claims, language and context with:

• Claims that are specific and supported by evidence.
• Language that is clear, regulatorily-aligned and unlikely to mislead.
• Context carefully considered with material qualifications and boundaries.

Those organisations can then choose to publish their Transparency Reports alongside a verified badge.

That public report does not endorse performance. It demonstrates that the communication itself has been independently assessed before publication.

In practice, this gives responsible organisations something valuable, a visible signal of disciplined, evidence led communication.

2. Creating Positive Pressure Within Sectors

Awareness changes behaviour.

When stakeholders such as investors, procurement teams, regulators and journalists begin to recognise what truMRK represents, a new question emerges.

Has this been independently reviewed?

In sectors where truMRK is well known, organisations that publish Transparency Reports will stand out.

Those that do not will face greater scrutiny.

For organisations whose sustainability communications are currently vague, selective or overstated, this creates a clear choice.

Continue publishing without independent scrutiny and accept higher risk and comparison.

Or strengthen claims, improve evidence, clarify language and make them robust enough to withstand review.

If a Transparency Report is unlikely to show strong scores, organisations will hesitate to publish one. That hesitation itself becomes informative.

Over time, the simplest route to participation in truMRK is improvement to communication.

This is how standards shift, not through accusation, but through visibility of best practice.

3. A Licence to Operate in Communication

In sectors where sustainability claims are commercially significant, credibility increasingly affects market access.

When independent review becomes common practice, it will begin to function as a practical licence to operate in communications.

Not in a legal sense, truMRK does not regulate markets. But in a reputational and commercial sense.

When it is recognised and understood, a published Transparency Report will signal that claims have been stress tested, evidence has been examined, language has been assessed for risk and context has been considered.

Without that signal, organisations will face tougher questions, longer procurement processes or heightened scrutiny.

With it, they demonstrate proactive risk management. That shift has industry wide implications.

A Practical Path to Higher Standards

The significance of truMRK’s impact will depend on the participation of good corporate communicators.

When credible organisations publish Transparency Reports, they create a benchmark.

When stakeholders recognise and value that benchmark, others will follow.

And because following requires clearer claims, stronger evidence and fuller context, then industry wide standards of communication improve. Acting transparently will become the norm.

That is how voluntary frameworks create change, by aligning reputation with transparency.
