How Can a Business Avoid Greenwashing on Its Website?
Make environmental website claims specific, evidenced and current, and avoid turning narrow improvements or estimates into broad green promises.
Part of our guide: Sustainable Websites: A Practical Guide for Small Businesses
A business can avoid greenwashing by making environmental claims that are specific, supportable and clear about their limits. The presentation matters as well as the wording: a leaf badge or sweeping headline can imply more than the evidence establishes.
Do not describe a whole company, product or website as environmentally harmless because one part has improved. Explain what changed, what was measured and what remains outside the claim.
Define the subject of the claim
Is the statement about one page, the hosting electricity, a product’s packaging or the entire business? State that boundary plainly.
The CMA’s Green Claims Code emphasises truthful, clear and substantiated claims, fair comparisons and attention to relevant lifecycle impacts.
The sustainable website guide provides practical improvement ideas without assuming they justify a broad marketing label.
Thinking about your own rebuild?
Tell us about your business, your current website and what you would like to improve. We will help you work out the next step.
Use the same evidence-led approach when creating website content that attracts customers.
Match the wording to the evidence
A measured reduction in transferred image data can support a statement about that test. It does not automatically prove an exact reduction in annual carbon emissions.
If a figure comes from a calculator, identify it as an estimate and explain the method, date and assumptions where material.
Avoid adding false precision through several decimal places. The language should reflect the strength of the evidence.
Keep qualifications close
Important limits should be visible beside the claim, not hidden in a remote policy page. A reader should not need to investigate extensively to discover that a headline applies only to a narrow part of the service.
If the main statement cannot be made accurate with a short, understandable qualification, rewrite it.
Clear, supportable claims also help build customer trust.
Check imagery and badges
A nature photograph or green seal can imply environmental credentials even without a detailed sentence. Ask what a reasonable visitor is likely to infer.
Use real images honestly and do not invent a certification mark. If a third-party scheme is involved, follow its rules and make the scheme’s scope verifiable.
A self-created graphic should not resemble independent approval.
Compare like with like
If you compare a redesign with the old site, use representative pages and consistent conditions. Explain differences in content, functionality or measurement.
Do not compare a lightweight article with a competitor’s fully interactive booking journey and call the whole business greener.
The low-impact design guide helps describe concrete design choices instead of unsupported superiority.
Keep an evidence record
Save the source material, calculations, approvals and review date behind each public claim. Assign someone to update or withdraw it when circumstances change.
The CMA’s detailed environmental-claims guidance provides fuller context and examples.
Get qualified advice for significant consumer-facing claims or formal environmental reporting.
Be clear about who is responsible
Customers should be able to identify and contact the business making the statement. The contact-details guide supports that basic accountability.
If a supplier provides the evidence, do not copy the claim without checking whether it applies to your particular service and period.
Supplier changes, expired certifications and revised calculation methods can all affect the wording.
Prefer useful facts to sweeping labels
A statement explaining a specific improvement and its limitations can be more informative than “eco-friendly website” without context.
If the evidence is incomplete, continue the improvement work without turning it into a public claim yet. For help presenting measured website changes accurately, contact AfterWorks.
