In brief: Review every environmental claim before publication. Define exactly what it covers, the comparison baseline, period, method and evidence owner. Then assess the overall impression created by words, images, labels and omitted qualifications.
Greenwashing risk can arise even when one sentence is technically true. A broad product name, green imagery or a prominent percentage may imply a wider benefit than the evidence supports. A controlled review process helps marketing, sustainability, legal and product teams agree what can be said and what qualification must remain visible.
Make broad terms specific
Words such as green, sustainable, eco-friendly and low carbon need a defined attribute, boundary and basis. State whether the claim relates to a product, packaging, process, facility or company. Avoid implying an overall environmental benefit from one improved feature.
Test comparisons and percentages
Identify the baseline product, geography, period, unit and calculation method. Explain whether a percentage refers to recycled content, emissions, energy, waste or another measure. Ensure the comparison remains current and like-for-like.
Review the total presentation
Assess headlines, footnotes, icons, nature imagery, certifications and product names together. Qualifications should be close, legible and understandable. A small disclaimer may not correct a dominant misleading impression.
Control updates and evidence expiry
Assign an owner, review date and evidence location to each recurring claim. Product specifications, suppliers, electricity contracts and methodologies change. Remove or revise claims when their evidence no longer applies.
A practical implementation sequence
Create a claim register and a short approval form used before campaigns, packaging or product pages go live. High-risk claims should receive specialist review. Reuse approved wording only while the underlying scope and evidence remain unchanged.
- List every explicit and implied environmental claim.
- Define scope, baseline, period, method and evidence owner.
- Check imagery, labels and qualifications as one presentation.
- Approve wording through named business and review functions.
- Set an expiry or review date for every recurring claim.
For every step, retain the owner, source, reporting period, method, version, reviewer and known limitations. Estimates can be useful during transition, but they should never be presented as measured data.
Decision risks to control
- Using broad green language for one narrow improvement.
- Making comparisons without a clear baseline or functional unit.
- Relying on a small disclaimer to correct the main impression.
The claim file should contain the approved wording, calculations, product specifications, supplier evidence, certificates, comparison basis, visual review and approval history. Keep a public correction path for claims that later prove incomplete or outdated.
Frequently asked questions
Can a true statement still be misleading?
Yes. The overall impression, missing context or imagery may imply a broader benefit than the narrow statement supports.
Are certifications enough evidence?
Only for the exact scope, criteria, product and validity period of the certification. They do not support unrelated claims.
Should every claim receive legal review?
Use a risk-based process. Broad, comparative, regulated or high-profile claims warrant specialist review; routine claims still need controlled evidence.
What if new data changes the claim?
Reassess the wording, update or remove it promptly, document the decision and correct material public information where necessary.
