ESG Marketing Strategy: Substance Over Signal

An ESG marketing strategy is a structured approach to communicating a company’s environmental, social, and governance commitments in ways that build trust, differentiate the brand, and support commercial growth. Done well, it connects genuine business behaviour to audience values. Done poorly, it becomes a reputational liability.

The gap between those two outcomes is almost always rooted in the same problem: the marketing runs ahead of the substance. Companies reach for the communications before the underlying commitments are real, measurable, or embedded in how the business actually operates.

Why ESG Marketing Has Become So Difficult to Get Right

I have sat across the table from senior marketers at some serious companies, and the ESG conversation almost always goes the same way. Someone in comms or brand has been tasked with “doing something on sustainability.” There is a set of aspirational commitments from the CEO. And the brief lands with the marketing team before anyone has checked whether the business can actually substantiate the claims.

That is not a communications problem. That is a governance problem. And no amount of careful copywriting fixes it.

The scrutiny around ESG claims has intensified significantly. Regulators in the UK and EU have moved to tighten rules around environmental claims. Journalists and campaign groups have become adept at pulling apart sustainability messaging. And audiences, particularly younger ones, have developed a fairly sharp instinct for when a brand is performing values rather than living them.

This is the environment in which ESG marketing strategy now has to operate. The tolerance for vague aspirational language has evaporated. What remains is a genuine opportunity for companies that have done the work, and a genuine risk for those who have not.

If you are thinking about how ESG fits into a broader commercial growth framework, the Go-To-Market and Growth Strategy hub covers the wider strategic context in which these decisions sit.

What Separates Credible ESG Marketing from Greenwashing

Greenwashing is not always deliberate. Some of the most egregious examples I have seen came from marketing teams who genuinely believed the claims they were making. The problem was that the claims were built on commitments rather than actions, on targets rather than results, and on the best-case interpretation of ambiguous data.

Credible ESG marketing has a different character. It is specific. It names numbers, dates, and methods. It acknowledges where progress is incomplete. It does not treat a net-zero pledge as equivalent to net-zero achievement. And it does not use the language of transformation to describe what is, in practice, an incremental operational improvement.

When I was judging the Effie Awards, one of the things that separated the work that held up under scrutiny from the work that did not was this: the credible entries could tell you exactly what changed in the business, not just what changed in the advertising. The ESG-linked campaigns that were genuinely effective had a business behaviour at their core, not a media budget.

The practical test is simple. Before any ESG claim goes into market, ask whether you could defend it in front of a journalist who was actively looking for a story. If the honest answer is no, the claim is not ready.

How to Build an ESG Marketing Strategy That Holds Together

Building a credible ESG marketing strategy is not fundamentally different from building any other kind of marketing strategy. It requires an honest audit of where you are, a clear view of where you are going, and a communications approach that accurately represents the gap between the two.

Start with the audit, not the brief

Before any positioning work begins, the business needs an honest internal audit of its ESG position. What are the actual environmental impacts of the operation? What social commitments exist, and how are they tracked? What governance structures are in place, and are they genuinely independent?

This is not a marketing exercise. It requires input from operations, legal, finance, and HR. Marketing’s role at this stage is to ask the questions that a sceptical external audience would ask, not to frame the answers for maximum positive impact.

I ran this process with a client in the manufacturing sector some years ago. The initial brief was to build a sustainability campaign around their new packaging initiative. When we audited the full picture, the packaging improvement was real but represented a small fraction of their overall environmental footprint. Campaigning loudly on that one element while the broader picture remained unaddressed would have been a gift to anyone who wanted to write a critical piece about the company. We scaled the communications back, focused on honest progress reporting, and built credibility over time rather than claiming a position they had not yet earned.

Define what ESG actually means for your specific business

ESG is a framework, not a template. The material issues for a financial services firm are different from those facing a food manufacturer, a logistics company, or a technology business. Effective ESG marketing strategy starts with identifying which issues are genuinely material to the business and its stakeholders, rather than trying to address every possible dimension of environmental, social, and governance performance.

Materiality is a concept borrowed from financial reporting, and it is a useful discipline here. What are the ESG factors that could genuinely affect the business’s ability to create value? Those are the ones worth communicating about, because they are the ones where the business has both the greatest accountability and the greatest opportunity to demonstrate credibility.

BCG’s work on aligning brand strategy with go-to-market execution is worth reading in this context. The principle that brand positioning needs to be grounded in operational reality applies directly to ESG. A brand position built on commitments the business cannot deliver creates fragility, not strength.

Build the messaging architecture around evidence, not aspiration

The strongest ESG messaging is built on a hierarchy that moves from evidence to aspiration, not the other way around. Start with what the business has demonstrably achieved. Layer in what is currently in progress, with specific timelines and accountability. Then, and only then, introduce longer-term aspirational commitments, clearly framed as targets rather than achievements.

This structure does something important. It signals that the business understands the difference between what it has done and what it intends to do. That distinction is exactly what audiences have learned to look for, and exactly what most ESG marketing fails to make clearly.

The language matters too. Words like “committed to,” “working towards,” and “on a experience to” have been so thoroughly overused in ESG communications that they now function as warning signals rather than reassurances. Specific language, specific metrics, and specific timeframes do more work than any amount of aspirational framing.

The Audience Problem in ESG Marketing

One of the things I have noticed across twenty years of working with brands is that companies often have a much clearer picture of what they want to say than they do of who they are actually saying it to. ESG marketing suffers from this more than most.

The audiences for ESG communications are not homogeneous. Institutional investors have a different set of concerns and a different level of sophistication than retail consumers. Regulators want different things than employees. NGOs and campaign groups are looking for different signals than supply chain partners. A single ESG narrative that tries to serve all of these audiences simultaneously usually ends up serving none of them particularly well.

This is where segmentation thinking, which is second nature in most marketing contexts, often gets abandoned in ESG work. The instinct is to produce a single set of sustainability communications and push them broadly. The more effective approach is to identify which audiences matter most to the specific business outcomes you are trying to support, and build communications that speak precisely to what those audiences need to see.

For a B2B business trying to protect and grow enterprise relationships, that might mean detailed supply chain transparency reporting. For a consumer brand trying to maintain relevance with younger shoppers, it might mean visible, verifiable commitments on specific product-level claims. These are different communications problems, and they require different approaches.

Understanding where these audiences exist in the purchase experience, and what they need at each stage, is part of a broader go-to-market challenge. The growth strategy resources on this site explore that broader framework in more depth.

Where ESG Fits in the Go-To-Market Plan

ESG is not a campaign. This is worth saying plainly, because it is still treated as one in a lot of organisations. A campaign has a start date, an end date, a budget, and a set of KPIs. ESG positioning is a long-term strategic commitment that affects how the brand is perceived, how the business is regulated, how talent is attracted and retained, and how investors assess risk.

Trying to run ESG as a campaign creates exactly the wrong incentives. It pushes teams towards maximising short-term impact rather than building long-term credibility. It creates pressure to make claims that are more compelling than they are accurate. And it means that when the campaign ends, the commitment appears to end with it.

The companies that have built genuine ESG credibility have done it by treating ESG communications as an ongoing reporting function rather than a marketing activation. They publish progress reports. They acknowledge setbacks. They update their targets when circumstances change. This is less exciting than a campaign, but it is far more durable.

In go-to-market terms, ESG positioning works best when it is integrated into the overall brand architecture rather than sitting alongside it as a separate initiative. The values the business communicates through its ESG work should be consistent with the values it communicates in its product marketing, its employer brand, and its customer experience. Inconsistency across these touchpoints is one of the fastest ways to undermine credibility.

Vidyard’s analysis of why go-to-market feels harder now touches on a related challenge: the growing complexity of aligning multiple internal stakeholders around a coherent external message. ESG amplifies that complexity significantly, because the stakeholders who need to be aligned include legal, operations, and finance, not just marketing and sales.

The Measurement Challenge in ESG Marketing

Measuring the commercial impact of ESG marketing is genuinely difficult, and anyone who tells you otherwise is probably selling you something. The causal chain between an ESG commitment and a business outcome is long, indirect, and full of confounding variables.

That said, the difficulty of measurement is not a reason to avoid measurement. It is a reason to be honest about what you are measuring and what you are not.

There are broadly three levels at which ESG marketing can be measured. The first is communications effectiveness: are the right audiences receiving and understanding the ESG messages? This is measurable through standard research methods. The second is perception change: is the business’s ESG reputation improving among the audiences that matter? This requires longitudinal tracking, but it is achievable. The third is commercial impact: is improved ESG perception translating into business outcomes? This is the hardest to isolate, but proxy metrics like customer retention rates, talent acquisition costs, and investor sentiment can give a reasonable directional read.

I spent a long time in my career over-indexing on lower-funnel attribution. I thought the cleaner the measurement, the more valuable the activity. What I eventually came to understand is that the activities with the cleanest measurement are often the ones with the least strategic importance. ESG sits at the other end of that spectrum. The measurement is messy, but the strategic stakes are high.

The honest approximation principle applies here. You do not need to prove that your ESG communications drove a specific percentage increase in revenue. You need to build a reasonable case that they are contributing to the conditions in which the business can grow, retain talent, and manage regulatory risk. That is a different kind of measurement, but it is not a lesser one.

The Organisational Conditions That Make ESG Marketing Work

The most common failure mode I have seen in ESG marketing is not a communications failure. It is an organisational one. Marketing is asked to communicate commitments that have not been operationally embedded. Legal has not signed off on the claims. The operations team has not been briefed. The CEO’s public statements are ahead of what the business can actually deliver.

This creates a fragile situation. The communications are out in the world, creating expectations that the business is not yet equipped to meet. When the gap becomes visible, and it usually does, the reputational damage is disproportionate to the original overclaim.

The organisational conditions that make ESG marketing work are not complicated, but they require genuine cross-functional alignment. There needs to be a clear owner for ESG performance, separate from but connected to the marketing function. There needs to be a process for verifying claims before they are published. And there needs to be a willingness at the leadership level to communicate honestly about progress, including the parts that are not going as planned.

Forrester’s research on go-to-market execution challenges identifies internal misalignment as one of the most persistent barriers to effective market communication. ESG makes that misalignment more visible and more consequential than almost any other marketing context.

There is also a talent dimension here. The skills required to build credible ESG communications are different from the skills required to build product campaigns. They include an understanding of sustainability reporting frameworks, regulatory requirements, and stakeholder engagement. Most marketing teams do not have this in-house, and building it takes time.

The Competitive Opportunity in ESG Marketing

Here is something that does not get said enough: for companies that have genuinely done the work, ESG is a significant competitive opportunity, and most of them are not taking it.

The greenwashing scandals of recent years have created a market dynamic where audiences are sceptical of ESG claims by default. That scepticism is a problem for companies with thin credentials, but it is an advantage for companies with genuine ones. If your competitors are overclaiming and you are accurately reporting real progress, the contrast does work for you. Not immediately, and not through a single campaign. But over time, the businesses that have built authentic ESG credentials will have a more durable brand position than those that have not.

The opportunity is particularly significant in categories where ESG is a genuine purchase driver, rather than a hygiene factor. In B2B procurement, sustainability credentials have become a meaningful factor in supplier selection for a growing number of large organisations. In consumer categories like food, personal care, and financial services, ESG-aligned products command measurable pricing power in certain segments.

BCG’s work on go-to-market pricing strategy is relevant here. The ability to command a price premium is one of the clearest indicators of genuine brand differentiation. ESG credentials, when they are real and well-communicated, contribute to that differentiation in specific segments. But only when they are real.

This connects to something I believe more broadly about marketing. If a company genuinely does the right things, treats customers well, operates responsibly, and delivers on its promises, marketing’s job becomes significantly easier. Marketing is often called upon to compensate for a product or a business that is not quite good enough. ESG is an area where the inverse can be true: a business that is genuinely operating responsibly has a marketing asset that most of its competitors cannot credibly claim.
