Why now is the best time to tell your organization's sustainability story. (Thank you CSRD.)

For years, a company’s sustainability story had a clear home: inside the 100+ pages of a massive sustainability report. These reports captured the full scope of a company’s efforts — carefully, comprehensively and all at once.

But what lived in those pages didn’t always make its way into marketing campaigns that actually drove brand preference and sales. Most often, the stories stayed buried within pages, within pages, within pages on websites, invisible to the customers and consumers who most wanted to hear those stories.

That’s about to change.

The Corporate Sustainability Reporting Directive (CSRD) requires very large companies — including non-E.U. companies doing a certain amount of business inside the E.U. — to report on environmental, social and governance (ESG) practices starting in the next few years in a very specific way to allow for apples-to-apples comparisons between companies.

CSRD will raise the bar on disclosures, demanding more rigor, standardization and data-driven evidence. Soon, every company will report exactly the same metrics, and every “report” will look more like a 10-K than a storybook.

To most sustainability leaders, this is anxiety-inducing. They are actively asking the question, “now how will we tell our sustainability story?!” The truth is, when the story was trapped inside a report and buried on a corporate website, the story wasn’t truly being told, which was a missed opportunity for marketers. Now, marketers and sustainability leaders have an opportunity to craft a compelling sustainability narrative and communicate it to the most important audiences through the channels where they’re likely to see it — and drive preference and sales as a result.

And before you say, “Whew! I lead sustainability or comms for a company that falls outside of the CSRD requirements,” mark my words: The standard the biggest companies are held to will become the norm and, in time, everyone will expect you to change your reporting to mirror the CSRD format as closely as possible.

Why telling your sustainability story matters now

At the Marketing Communications Agency inside ERM, we have been surveying people every year for 20 years to understand their beliefs and expectations on a whole range of people and planet topics. We’ve seen growth in the importance of sustainability communications all along the way — and it hasn’t slowed down just because politics have taken a right turn. Nearly two-thirds of people around the world say a company’s social and environmental actions influence their buying decisions — 64% for social issues, 67% for environmental reputation (Global Eco Pulse^® 2025).

People are paying attention: consumers, employees and investors want to see real action on reducing emissions, supporting communities and driving impact. Brands that communicate transparently and authentically are rewarded with consumers’ pocketbooks, while silence or vague claims can erode trust.

Yet many companies fall into “greenhushing” — doing the work but not sharing it. Strategic storytelling can bridge that gap, turning action into reputation, trust and measurable business results.

Crafting stories that resonate

Successful sustainability storytelling rests on three pillars:

• Credibility first: Every claim must be verifiable, grounded in data and supported by accessible information. Don’t hide it in reports. Make it visible wherever your audience encounters your brand, from packaging to product pages to campaigns.
• Relevance matters: Not every company can or should cover every sustainability topic. Focus on what truly matters to your business, brand and customers. Build your story on that foundation.
• Consistency builds trust: Sustainability can’t be a one-off message. Repetition across channels ensures that by the time someone is making a purchase decision, they already know what you stand for.

Trust isn’t built in a moment — it’s built over time through proof and repetition.

Integrating sustainability IS a story

As every Chief Sustainability Officer knows, sustainability impacts nearly every aspect of a business, especially a company’s bottom line. Plus, stronger sustainability actions often translate to greater resilience. If a manufacturer lowers water consumption in operations, for example, it becomes more resilient in the event of local water scarcity. The company’s operations — and business income — are less likely to be disrupted, confirming its financial health over time.

Sustainability and financial vitality are often interdependent — and this interplay is precisely what the CSRD, and the related European Sustainability Reporting Standards (ESRS), seek to uncover. In responding to the CSRD, companies can do more than answer to regulation. They can gain an opportunity to share how integrating sustainability across the business reduces risk, builds resilience and prepares the company for the long term.

These topics are not only for investors. There are numerous benefits to demonstrating the financial advantage of sustainability. For instance, this story can help retain talent, as employees feel more secure in planning their career with the business. Or supply chain partners may be inclined to sign longer contracts, as they see the company’s long-term viability, in both financial and sustainability terms.

Keep in mind, too, the CSRD and ESRS have been refined to uncover the critical story of sustainability and its impact across the business. Initially, we heard a lot of clients describe the regulations as onerous. This complaint also made its way to the E.U. advisory group behind these rules. As a result, they have reduced the mandatory ESRS data points by 61% and completely removed all voluntary disclosures. Now companies can get to the story of sustainability and business impact in a faster, clearer way.

Bridging the gap: doing + saying 

In today’s sustainability landscape, storytelling must connect doing and saying. What you say only matters if it’s backed by proof. What you do only matters if people hear and understand it. For too long, an industry gap has existed between exhaustive sustainability reports and generic marketing campaigns — and that’s precisely where effective communication must operate.
