Customers want evidence, not slogans
Many businesses want to share their sustainability efforts, but customers are becoming more cautious about environmental claims. Greenwashing occurs when claims are exaggerated, misleading or unsupported by evidence. Effective sustainability communication focuses on facts, actions and measurable improvements rather than broad promises or marketing language.
Start with what you can prove
Before making any sustainability claim, ask whether you can support it with evidence. Examples include reducing electricity consumption, introducing reusable packaging or increasing recycling rates. If you cannot demonstrate the action or measure the result, it is better not to make the claim.
Avoid vague language
Terms such as 'eco-friendly', 'green' or 'sustainable' can be interpreted in different ways. Instead, explain exactly what has changed. For example, 'we reduced packaging by 30%' is clearer and more credible than saying a product is environmentally friendly. Specific information builds trust.
Be honest about the journey
No business is perfect. Customers often respond positively when organisations acknowledge challenges and explain what they are doing to improve. Transparency demonstrates commitment and reduces the risk of accusations that sustainability claims are misleading or exaggerated.
Communicate progress regularly
Sustainability communication should focus on progress rather than perfection. Share updates when improvements occur, report measurable outcomes and explain future priorities. Consistent, evidence-based communication helps build long-term credibility with customers, suppliers and employees.
