Avoiding Greenwashing and Implementing True Sustainability: Companies often face the challenge of communicating their sustainability efforts credibly without falling into the greenwashing trap. Greenwashing means making environmental claims that are misleading or unsubstantiated. This can destroy trust and result in legal consequences. How to Avoid the Trap of Greenwashing Marketing According to a 2022 report by the European Commission, over 42% of green claims made by companies in the EU were exaggerated, false, or deceptive, underscoring the widespread nature of greenwashing and the need for vigilance.

In 2020, Ryanair called itself Europe’s most environmentally friendly airline—the result: lawsuits, loss of trust, and a PR disaster. This example shows: those who engage in greenwashing lose more than just their reputation. The airline’s claims were found to be misleading by the UK Advertising Standards Authority, which banned the ads and highlighted the importance of substantiating environmental statements. Source

The most important tips at a glance:

• Set clear goals: Define measurable and realistic sustainability objectives. For example, Unilever’s Sustainable Living Plan set out to halve the company’s environmental footprint by 2030, providing a clear and ambitious benchmark. Source
• Use data: Back up claims with verifiable figures and independent audits. Companies like IKEA publish annual sustainability reports audited by third parties, enhancing credibility. Source
• Show transparency: Communicate both successes and challenges openly. Honest reporting, such as Patagonia’s acknowledgment of ongoing environmental challenges, builds trust. Source
• Avoid greenwashing: Steer clear of vague, one-sided, or unsubstantiated environmental statements. For more on greenwashing, see greenwashing.
• Comply with legal requirements: Follow EU directives such as the CSRD and the Green Claims Directive. The upcoming Green Claims Directive will require companies to provide scientific evidence for their environmental assertions. Source

Why is this important?

Greenwashing not only damages credibility, but also the financial stability of a company. According to a 2023 survey by McKinsey, 66% of consumers are willing to pay more for sustainable brands, but only if they trust the claims.

Green Claims - Doing it Right with Confidence

Developing an Effective Theory of Change

A clear theory of change connects actions with measurable results and provides a solid foundation for ESG initiatives that are both credible and actionable. The Science Based Targets initiative (SBTi), for example, helps companies align their climate goals with the latest climate science, ensuring that actions lead to measurable results. Source

Key Elements and Steps

To develop an impactful theory of change, a structured approach is crucial:

• Define and analyze goals
  Start with an analysis of the current situation and set realistic, measurable objectives. The Future-Fit Business Benchmark can help assess the status quo and set ambitious yet achievable sustainability goals.
• Plan actions
  Create a detailed plan with clear responsibilities and the necessary resources. Breaking it down into manageable milestones makes it easier to regularly track progress.
• Develop a KPI framework
  Develop a system with key indicators for environment, social, and governance. Examples: CO₂ emissions, energy consumption, and waste in the environmental area; working conditions and diversity in the social area; compliance and transparency in governance. The GRI Standards can serve as a guide.

Example: A textile company wants to reduce its CO₂ emissions. The action: switching to recycled materials. The assumption: recycled materials cause 30% fewer emissions. The goal: reduce CO₂ by 100 tons per year. Externally validated by LCA. Life Cycle Assessment (LCA)

Review and Reporting

Regular reviews are essential to ensure goals are met. Tools like the SDG Impact Assessment Tool help systematically evaluate progress toward the UN Sustainable Development Goals. According to the World Business Council for Sustainable Development, companies that conduct annual sustainability reviews are 30% more likely to achieve their targets. Source

Key steps for verification:

• Collect and analyze data
  Continuous data collection and analysis allow for accurate measurement of progress.
• Include external audits
  Independent auditors can enhance the credibility of results.
• Document deviations
  Identify deviations and adjust actions accordingly.
• Communicate results transparently
  Open communication builds trust and demonstrates commitment.

This approach ensures your sustainability strategies are built on a solid foundation and achieve real progress. Tools and frameworks such as the GRI Standards or the SDG Impact Assessment Tool offer valuable support.

Steps to Avoid Greenwashing

To avoid greenwashing, clear actions and a well-founded approach are essential. The goal is to design sustainability initiatives credibly and transparently, supported by systematic audits and reliable data. A Harvard Business Review analysis found that companies with robust internal controls and transparent reporting are less likely to be accused of greenwashing. Source

Establish Internal Controls

A solid control system is the first step to ensuring credible sustainability statements. This includes:

• Sustainability committee: A team from various departments that reviews all sustainability statements before publication.
• Documentation processes: Standardized procedures that fully and transparently document all sustainability measures.
• Training programs: Regular training for employees to keep them up to date on current standards and requirements in the field of sustainability.

With these internal structures, deviations can be identified and avoided early on.

Use Data and Analytics

Automated data collection and analysis are central tools for tracking sustainability goals and preventing negative developments. Companies should:

• Use automated data collection to continuously monitor CO₂ emissions, energy consumption, and waste.
• Deploy analytics tools that identify trends and flag potential issues.
• Conduct regular audits to ensure the quality and reliability of collected data.

"According to the rationale of the CSRD EU directive, customers, suppliers, employees, investors, lenders, and other business partners of companies should use the information in particular to adjust business relationships. Politics and civil society should also be able to demand more targeted accountability from companies."

In addition to data-driven approaches, it is important to comply with legal frameworks.

Comply with Legal Requirements

Compliance with legal requirements is essential in Germany and the EU. The most important regulations include:

• EU Green Claims Directive: Environmental claims must be scientifically substantiated. Green Claims Directive
• German UWG: Misleading environmental claims are considered anti-competitive and can have legal consequences.
• CSRD Directive: Companies are required to report comprehensively on sustainability metrics in areas such as climate, environment, diversity, and social responsibility. CSRD Overview

By combining these measures, companies can ensure their sustainability strategies are credible, verifiable, and successful in the long term.

Clear Sustainability Communication

Formulate ESG Statements Clearly

Clear ESG statements strengthen trust in a company. To be credible, they should be precise, measurable, and supported by data. The Task Force on Climate-related Financial Disclosures (TCFD) recommends that companies disclose climate-related risks and opportunities in a standardized, data-driven way to enhance transparency. Source

Principles for effective ESG communication:

• Set concrete goals: Instead of general statements, companies should formulate tangible and measurable objectives.
• Data-driven statements: Every claim should be backed by verifiable data.
• Show transparency: Address both successes and failures openly.

"To communicate authentically about sustainability initiatives, organizations should describe their efforts in concrete terms, back up their statements with data, and report transparently on both successes and failures." – Jasper Steinhausen

An example from practice: Ryanair falsely claimed to be climate-friendly in 2020, leading to significant credibility issues.

What is an ESG KPI for investors is often a cultural issue for employees. Credible communication must address both perspectives.

What Doesn’t Work: Common Mistakes in ESG Communication

Many companies rely on elaborate ESG reports or high-profile campaigns—but without substance, these quickly come across as untrustworthy. Typical pitfalls:

• One-sided success stories: Reports that only show progress but do not address deviations from targets, challenges, or lessons learned.
• Green PR instead of Green Impact: Campaigns with strong visuals but no measurable impact or reliable data.
• Non-transparent methodology: ESG goals without explanation of the data basis or underlying assumptions (e.g., for CO₂ compensation or “climate-neutral” products).

A credible ESG approach does not require a perfect record—but does require openness, verifiable actions, and a willingness to continuously improve.

Reporting Methods and Tools

Sustainability reports require structured approaches and suitable tools. From 2024, the CSRD directive will increasingly require companies to disclose their sustainability performance. The Global Reporting Initiative (GRI) and the Sustainability Accounting Standards Board (SASB) provide widely recognized frameworks for reporting. GRI Standards SASB

Key components of a well-structured sustainability report:

A successful example is provided by The Body Shop with its “Enrich, Not Exploit” campaign. The company clearly describes its goals, challenges, measures implemented, and current progress. Source

For compelling sustainability communication, companies should focus on information and education rather than just advertising. The key is to actively involve stakeholders and strike a balance between transparency and clarity.

Conclusion: Building Trust Through Action

The approaches presented make it clear: transparency, clear metrics, and external verification are crucial. Only consistent, data-driven action can build trust in sustainability communication. According to Edelman’s 2023 Trust Barometer, 88% of institutional investors say that companies that are transparent about their ESG progress are more likely to earn their trust. Source

Three core pillars form the foundation for long-term success:

These three building blocks create the framework for actionable and verifiable measures. A prime example of credible commitment is provided by Patagonia with its guiding principle:

"Build the best product, cause no unnecessary harm, use business to inspire and implement solutions to the environmental crisis"

Key implementation aspects:

• Disclosure of emissions data
• Transparent investments in technology
• Compliance with international standards

Experience shows: companies that underpin their sustainability goals with concrete actions and regularly report on progress gain the trust of their stakeholders. Measures must be strategically planned, supported by measurable evidence, externally audited, and continuously updated.

As already explained, clear figures, external audits, and open communication build trust. Only those who regularly review and further develop their strategy remain credible. These adjustments show that commitment is more than just a declaration of intent.

These principles are the starting point for further discussion and a sustainable dialogue.
