Why greenwashing matters for digital products

Claims about a website or app being “green” or “carbon neutral” are increasingly visible in product pages, hosting offers and marketing copy. Vague or unsupported assertions damage trust, invite regulatory scrutiny and make it harder to compare providers. Digital teams need practical rules to turn good intentions into defensible, verifiable statements.

Common types of misleading claims you will see

• Absolute labels without boundaries For example stating a site is “carbon neutral” or “zero emissions” without specifying which emissions are included, which time period is covered and whether reductions or offsets are used.

• Imprecise renewable energy claims For example saying hosting is “100 percent renewable” when the provider buys unbundled energy certificates without explaining timing or contractual arrangements.

• Performance framed as sustainability For example promoting a smaller page weight as proof the product is “eco friendly” without translating that into a measurable emissions or energy metric.

• Cherry picked comparisons For example claiming the product is “more sustainable” than competitors without stating the comparison baseline, metrics or methodology.

• Overstating offsets or removals For example implying that buying a volume of offsets fully cancels ongoing operational emissions without specifying offset standard or retirement proof.

Why these claims are risky

Regulators in multiple jurisdictions have issued guidance that requires environmental claims to be truthful, substantiated and clear. Misleading claims can lead to corrective orders, removal of advertising and reputational harm. Beyond legal risks, vague statements make it difficult for customers and procurers to compare offerings and to hold vendors accountable.

Principles for verifiable digital sustainability claims

Apply basic principles before publishing any sustainability statement. These principles keep language precise and make it possible for third parties to validate claims.

Define scope and boundary

State clearly which activities are included. Examples of boundaries relevant to digital products are hosting energy, content delivery, development workflows, analytics and third party tags. Distinguish between emissions from your infrastructure and emissions from users devices when applicable.

Provide a timeframe and baseline

Every claim should include the period it covers and the baseline that was used for comparisons. If you report reductions, show the reference year or the measurement used for comparison.

State the methodology and units

Explain how you measured or estimated energy or emissions and which conversion factors or tools you used. Use common units such as kilograms or metric tons of CO2 equivalent and indicate whether the calculation follows an established protocol.

Disclose verification and supporting evidence

Say whether the claim was verified and by whom. If you relied on supplier statements, link to or summarise the supplier evidence. Keep supporting data available for procurement or audit requests.

Safer wording templates and examples

Below are phrase templates that marketing and product teams can adapt. Each template is intentionally specific so readers can check or verify the claim.

Hosting and energy

• Poor phrasing “Hosted on 100 percent green energy.”

• Safer phrasing “Our hosting provider purchases renewable energy certificates for the electricity used by our servers and reports monthly supply data. This statement covers electricity consumption at our primary data centre during calendar year 2025.”

Emissions and offsets

• Poor phrasing “Carbon neutral website.”

• Safer phrasing “We estimate the annual operational emissions associated with hosting and CDN delivery and compensate residual scope 2 emissions through verified carbon credits retired with registry receipts. Our published methodology and registry retirement IDs are linked in the sustainability report.”

Performance framed as sustainability

• Poor phrasing “Eco friendly product with low data usage.”

• Safer phrasing “Optimisations reduced average page transfer size by X percent compared to the baseline measured on YYYY MM. Reduced transfer translates into lower network energy demand according to the measurement method described in our methodology document.”

Comparisons and rankings

• Poor phrasing “More sustainable than competing platforms.”

• Safer phrasing “In a May 2025 technical audit we measured hosting energy intensity for three platforms using the same test pages and reported results under the same measurement assumptions. Methodology and raw data are available on request.”

Practical checklist before publishing any sustainability claim

1. Have you defined the scope and boundaries explicitly?

2. Does the statement include a clear timeframe and baseline?

3. Is there a documented methodology and are units of measure stated?

4. Can you provide supplier evidence and, if used, offset registry receipts?

5. Has the claim been reviewed by legal or sustainability governance to check against local guidance?

How to handle offsets and renewable energy language responsibly

Offsetting and renewable energy purchases can be legitimate parts of a corporate emissions strategy. They become problematic when they are presented as a substitute for measurable reductions or when the mechanisms are opaque.

Offsets

If you mention offsets, say which registry and which standard the credits come from. Avoid implying that offsets remove historical emissions from the atmosphere with the same immediacy as emissions reductions. State whether offsets cover a specific subset of emissions and whether they are a temporary bridging measure as you work to reduce operational emissions.

Renewable energy claims

Renewable energy certificates, power purchase agreements and physical supply are different mechanisms. Be explicit about which mechanism is in use, the geographic and temporal match to consumption and whether the provider uses short term or contractual instruments. If a claim depends on supplier level reporting, link to the supplier disclosure.

Labels and certifications worth considering

Third party labels add credibility when the underlying criteria, scope and verification are published. Select programmes that publish methodology and allow verification of claims through public registries or audit reports. Examples of credible inputs to look for are external verification, public methodologies and traceable registry entries for offsets or renewable certificates.

Real world copy examples to adapt

Marketing and product copy often needs short statements that are still accurate. Use one line for public pages and link to a deeper page that holds the methodology and evidence.

Short public line

“We work to reduce the emissions from our digital products and publish our measurement approach and mitigation steps in the sustainability report.”

Linked substantiation page

On a substantiation page provide the scope, method, datasets and any supplier evidence. Include a timestamp and an author or contact for questions.

Governance and internal roles

Make publishing a sustainability claim a cross functional step that includes product, engineering, marketing and legal. Keep a single source of truth for claimed metrics and a changelog that records measurement revisions. This reduces the risk of inconsistent statements across pages and collateral.

Suggested roles and responsibilities

• Product defines scope and ensures the claim accurately reflects product behaviour.

• Engineering supplies measurement data and validation of technical optimisations.

• Marketing drafts the external phrasing and links to substantiation.

• Legal or compliance checks phrasing against local advertising and consumer protection guidance.

When to seek external verification

External verification is especially valuable for statements used in procurement, investor communications or regulatory filings. Consider third party audits for baseline measurements, for supplier claims that are material to your assertion and for any offsets or certificates you rely on. Keep verification reports available to trading partners and procurement teams while preserving any commercially sensitive details.

Next steps teams can take this week

1. Inventory existing sustainability statements across the site and marketing materials.

2. For each statement, apply the checklist above and flag items that lack scope, timeframe or methodology.

3. Replace vague lines with safer phrasing and add links to a substantiation page that contains evidence and methods.

Clear, verifiable language protects your brand and creates useful comparisons for customers. Small changes to phrasing and a short substantiation page deliver outsized improvements in accuracy and trust.
