Net zero: How to communicate sustainability without greenwashing?

Achieving net zero is no longer a distant ambition, it’s a pressing expectation from stakeholders, regulators, and society at large. Companies must not only act but also communicate transparently about their environmental progress. In this article, we’ll explore how you can effectively share your sustainability journey without falling into the trap of greenwashing, and how the right tools, like EACs, can strengthen your efforts toward real, verifiable climate action. 

The challenge of communicating sustainability

Companies are increasingly encouraged to highlight their environmental progress, whether through emission reductions, investments in renewable energy, or broader societal initiatives. However, under this growing pressure, the risk of greenwashing remains very real. 

What are the reputational risks of greenwashing? (H3) 

• Loss of trust in the brand 
  Greenwashing, which is giving a misleading impression of environmental commitment, can erode trust among customers, investors, and partners, harming a company’s credibility in the long term. 

• Media backlash 
  Accusations often spark “name and shame” campaigns on social media and in the press, with lasting reputational impacts that crisis communications struggle to repair. 

• Obstacle to the green transition 
  Beyond brand damage, widespread greenwashing risks slowing the global low-carbon transition by disadvantaging genuinely committed companies and slowing real solutions. 

• Financial and regulatory sanctions 
  Finally, regulatory pressure across Europe is increasing. Under directives like the CSRD, companies face strict transparency requirements, with heavy financial and legal penalties for non-compliance or overstating sustainability progress.

Practices to avoid greenwashing

Communicating sustainability: Growing expectations from stakeholders and regulators

Regulatory changes mean companies can no longer rely on broad statements of good intentions. The regulatory landscape has become significantly stricter, especially with the adoption of the Corporate Sustainability Reporting Directive (CSRD) in Europe. This directive mandates detailed sustainability reporting for large companies, publicly listed firms, and soon, listed SMEs. 

Under the CSRD, companies must report on their Environmental, Social, and Governance (ESG) practices in accordance with strict standards known as the European Sustainability Reporting Standards (ESRS). These sustainability reports must be included in a dedicated section of the management report, offering a clear view of how the company’s activities impact the environment and society—and how ESG risks and opportunities influence its strategy and financial results. 

ESG Reporting requirements 

ESG reporting demands the disclosure of accurate and verifiable data. Companies must describe their data collection methods, clarify their verification processes, and ensure the reliability of the figures presented by using independent certifications. 

Another key requirement is the principle of double materiality, which means companies must assess both their impact on society and the environment, as well as how ESG factors influence their own performance and strategic direction. 

The new framework is being implemented progressively. Large companies must comply starting in 2025, while listed SMEs will follow in 2027 or 2029, depending on their size. 

Moreover, all reports must be published in a structured digital format (XBRL/xHTML) to facilitate comparison and analysis by stakeholders. 

How to build a solid sustainability communication strategy?

Transparency and honesty

The cornerstone of credible communication is transparency. You need to publish your organisation’s actual carbon footprint, covering at least scopes 1 and scope 2, and ideally scope 3, and clearly explain the methodologies used, along with any limitations or uncertainties. 

Instead of making unrealistic claims like “zero impact,” it is far more effective to openly acknowledge the challenges and describe the actions currently underway. This honest approach will resonate much better with the public and regulators alike. 

Additionally, it is crucial to back up any environmental claims with verifiable data from independent audits, certified reports, and credible sources. 

Clear and credible targets

Your sustainability commitments must be defined in a realistic and credible way. For instance, you might commit to reducing your emissions by 20% by 2030, aligned with recognised standards such as the SBTi. 

Avoid vague or exaggerated promises. Simply labeling a product as “eco-friendly” without specifics diminishes the credibility of your entire communication. Instead, set precise, measurable, and time-bound goals to strengthen the legitimacy of your messaging. 

Responsible and continuous communication

Sustainability communication should be seen as a continuous process—not a one-off campaign. It’s important to train your internal communication teams to ensure they fully understand the legal, regulatory, and ethical requirements for environmental claims. 

You also should maintain an ongoing dialogue with key stakeholders, including customers, NGOs, investors, employees, and others. Listening to their expectations and feedback—and adjusting your communication accordingly—is vital for continuous improvement and building long-term trust.
