How to Audit Environmental Claims on Your Website: A Step-by-Step Guide — GreenClaims Scanner

Every environmental claim on your website is a liability until proven otherwise. That's the reality under the EU Green Claims Directive, and it means auditing your web presence for green claims isn't optional — it's urgent.

Most companies don't even know how many environmental claims their website contains. Marketing copy evolves over years, different teams add content, and claims pile up in product descriptions, blog posts, about pages, and footer text that nobody reviews. A thorough audit catches everything.

Why Website Environmental Claims Need Special Attention

Your website is typically the most visible and permanent record of your environmental messaging. Unlike a social media post or print ad, web pages persist indefinitely and are accessible to regulators, competitors, NGOs, and consumers worldwide.

Under the ECGT, regulators can — and will — crawl company websites looking for non-compliant claims. Consumer protection organizations already do this. In 2024, the European Consumer Organisation (BEUC) systematically reviewed the websites of major brands and filed complaints based purely on website content.

The Scope of the Problem

A typical mid-size company's website contains 50-200 environmental claims across all pages. Most of them were written without considering regulatory compliance. Product pages are the worst offenders, but "About Us" sections, sustainability reports, press releases, and even job postings often contain environmental claims that trigger ECGT requirements.

The 7-Step Website Environmental Claims Audit

Step 1: Complete Claim Inventory

Before evaluating anything, you need to find everything. This is where most audits go wrong — they check the obvious pages (homepage, sustainability section) and miss the 80% of claims hiding elsewhere.

What to scan:

• Every product and service page
• Homepage and landing pages
• About Us / Our Story / Our Values sections
• Sustainability or CSR reports (web versions)
• Blog posts and articles
• Press releases
• Job postings (yes, "join our sustainable team" is a claim)
• Footer and sidebar content
• PDF documents hosted on the site
• Image alt text and meta descriptions

Doing this manually on a large site is impractical. Automated scanning tools can crawl your entire site and flag every environmental claim in minutes, categorizing them by type and risk level.

Step 2: Classify Each Claim

Not all claims carry the same risk. Classify each one using these categories:

By specificity:

• Explicit specific: "This product contains 75% recycled plastic" — verifiable, but needs substantiation
• Explicit generic: "We are committed to sustainability" — vague, high risk under ECGT
• Implicit: Green imagery, nature photographs, leaf icons without text — still regulatable

By claim type:

• Carbon/climate claims ("carbon neutral," "low emissions")
• Material claims ("recycled," "biodegradable," "organic")
• Process claims ("sustainably sourced," "ethically produced")
• Certification claims ("certified green," specific eco-labels)
• Comparative claims ("greener than," "more sustainable")
• Future commitments ("carbon neutral by 2030")

Check each claim against the list of banned and restricted terms under EU regulation.

Step 3: Map Substantiation Status

For every claim identified, document what evidence currently exists. Create a simple matrix:

Be honest in this step. "We think this is true" or "our supplier told us" is not substantiation under the ECGT. You need documented, verifiable scientific evidence.

Step 4: Risk Assessment

Prioritize your findings by combining two factors: regulatory risk and business impact.

Regulatory risk factors:

• Claims on high-traffic pages (more visibility = more scrutiny)
• Claims about hot-button topics (carbon neutral, biodegradable, organic)
• Generic unsubstantiated claims ("green," "eco-friendly")
• Claims that competitors could challenge
• Claims visible to EU consumers specifically

Business impact factors:

• Claims tied to product pricing (premium charged for "sustainable" features)
• Claims in advertising campaigns (higher regulatory attention)
• Claims that influence purchasing decisions

Step 5: Decide — Substantiate, Modify, or Remove

For each claim, you have three options:

Substantiate: If the claim is accurate and important to your marketing, invest in proper substantiation. This means life-cycle assessments, scientific studies, and eventually third-party verification.

Modify: If the claim is broadly true but poorly worded, rewrite it to be specific and substantiatable. "Eco-friendly packaging" becomes "Packaging made from 75% post-consumer recycled cardboard, certified by [specific certification]."

Remove: If the claim is vague, unsubstantiatable, or not worth the compliance cost, delete it. Don't hesitate — a missing claim costs nothing, but a non-compliant claim can cost millions.

Step 6: Implement Changes

Once you've decided what to do with each claim, execute systematically:

1. Remove all critical-risk claims immediately — don't wait for the full audit to complete
2. Update CMS templates that propagate claims across multiple pages (header, footer, product template)
3. Modify individual page claims according to your decisions
4. Update meta descriptions and alt text (often forgotten)
5. Check PDF documents and downloadable materials
6. Update cached versions — clear CDN cache, request Google recrawl

Step 7: Establish Ongoing Monitoring

An audit is a snapshot. Without ongoing monitoring, new non-compliant claims will creep back in within weeks as marketing teams publish new content.

Set up:

• Regular automated scans — monthly minimum, weekly for large sites. GreenClaims Scanner can automate this entirely.
• Content approval workflows — any new content mentioning environmental topics must be reviewed against your compliance checklist
• Training for content creators — marketers, copywriters, social media managers, product teams
• Quarterly substantiation reviews — evidence can become outdated as supply chains change

Common Audit Pitfalls

Only Checking the Sustainability Page

The sustainability section is where you expect environmental claims, so it's usually the most carefully worded. The real risks hide in product descriptions written by teams that don't think about compliance, in old blog posts nobody remembers, and in boilerplate footer text that was written five years ago.

Ignoring Visual Claims

A green leaf icon next to a product name is an environmental claim. Nature photography on your homepage can constitute an implicit claim. The ECGT covers the overall impression created by marketing, not just text.

Treating B2B Differently

If your B2B environmental claims can reach end consumers — through your website, shared marketing materials, or your clients' communications — they're in scope. "This is our B2B site" isn't a defense if consumers can access it.

Forgetting Third-Party Content

Customer reviews, partner logos, and third-party certifications displayed on your site are your responsibility. If you display a certification badge, you must verify it's current and accurate.

Tools and Resources for Your Audit

Manual auditing works for small sites (under 50 pages) but becomes impractical at scale. Here's what to use:

• Automated claim detection: GreenClaims Scanner crawls your entire site and identifies every environmental claim, classifying them by type and risk level
• LCA databases: The European Platform on Life Cycle Assessment (EPLCA) provides methodological guidance
• Regulatory reference: The ECGT compliance guide breaks down every requirement
• Banned terms checker: Our banned terms database flags prohibited language

After the Audit: Building a Compliance Culture

The audit reveals your current state. The real work is building systems so non-compliant claims don't appear in the first place.

This means making environmental claim compliance part of your content creation process, not an afterthought. Every piece of marketing content that mentions the environment, sustainability, ecology, or related topics should go through a compliance check before publication.

Companies that build this discipline now will have a massive advantage as enforcement ramps up. Those that treat compliance as an annual checkbox exercise will keep finding themselves in remediation mode — which is always more expensive and disruptive than getting it right the first time.

Start with the basics. Run your first scan, see what you're working with, and build your plan from there.
