The Corporate Dilemma: Is Greenhushing the New Greenwashing?

Environmental communication has become an uncomfortable exercise for many organizations. Say too much, and a company may be accused of greenwashing. Say too little, and it may be accused of greenhushing. One exaggerates environmental performance. The other keeps genuine work out of view. Neither gives stakeholders the information they need. The more credible approach lies between those extremes: organizations should communicate environmental progress when they have something useful to say, but the wording should stay within the boundaries of the evidence. That means being specific about what changed, how it was measured, what the claim covers, and what remains unfinished.

What greenwashing and greenhushing mean

Greenwashing occurs when an environmental message creates a stronger or broader impression than the underlying facts support. It can be deliberate, but it is often less obvious than an outright falsehood. A narrow improvement may be presented as if it applies to the whole company. A reduction in emissions intensity may sound like a reduction in total emissions. A product may be called “green” without explaining which attribute supports the description. A distant net zero target may receive attention even though the company has no credible transition plan.

Greenhushing is a different response to the same pressure. An organization may have a greenhouse gas inventory, a reduction project, or a credible target but choose not to discuss it publicly, usually out of fear that the work is not far enough along, that the data may change, that campaigners will criticize an imperfection, or that a regulator will question the wording. Greenhushing can feel cautious, but it is not always harmless. Stakeholders lose access to useful information. Customers and investors cannot distinguish serious work from inaction. Other organizations lose the opportunity to learn from approaches that work, and value chain partners have less primary data for Scope 3 accounting. Silence may reduce immediate attention, but it can weaken transparency and accountability over time.

The scale of the credibility problem

In a 2021 review of environmental claims on 344 websites, European consumer authorities found reason to believe that 42% of the claims were false or deceptive.¹ They also found that 59% were presented without easily accessible supporting evidence. On the other hand, South Pole's 2022 research involving more than 1,200 companies found that almost one in four did not plan to publicly communicate their science-aligned climate targets.² Together, these findings illustrate the problem: some organizations communicate beyond their evidence, while others withhold credible progress altogether.

Public examples

• Keurig Canada: in 2022, the Competition Bureau required the company to pay a $3 million penalty and change claims that its K-Cup pods were recyclable, because the pods were not widely accepted in municipal recycling programs.³
• Toyota: in 2023, the UK Advertising Standards Authority found that advertisements overstated the practical availability of rapid charging for the bZ4X electric vehicle.⁴
• KLM: in 2024, a Dutch court found that several advertisements in the airline's “Fly Responsibly” campaign created a misleading impression about the sustainability of flying.
• Pathways Alliance: in 2024, the Canadian oil sands group removed environmental content from its website and social media, citing uncertainty created by Canada's new anti-greenwashing provisions. The episode has been widely cited as an example of greenhushing, although it was not a legal finding of wrongdoing.⁵

Why organizations move from one extreme to the other

The recent rise in greenhushing is understandable. Sustainability claims are difficult to communicate in short headlines. Corporate inventories involve organizational boundaries, emission factors, estimates, and recalculations. Climate targets depend on future capital, technology, and supplier action.

The regulatory environment has also become more active. Marketing teams may not know which qualification is material. Sustainability teams may understand the data but have little control over how the claim is shortened for a website or advertisement. Legal teams may see uncertainty and advise the organization to avoid the subject entirely. These are usually governance problems before they are writing problems. A credible process brings the relevant functions together: technical staff confirm the calculation and boundary, communications staff test what a reasonable reader is likely to understand, legal or compliance staff consider the applicable rules, and senior management approves significant claims and accepts responsibility for the message.

Green claims rules are developing across markets

Regulators are moving in a similar direction: environmental claims should be specific, supported by evidence before publication, and presented without misleading words, images or omissions. Canada's Competition Act, amended through Bill C-59, requires adequate and proper testing for product-related environmental claims and adequate and proper substantiation for claims about businesses or business activities.⁶ The United States applies the FTC Act and Green Guides to deceptive environmental marketing. In the European Union, Directive (EU) 2024/825 restricts generic environmental claims, unreliable sustainability labels, and certain offset-based product claims. The United Kingdom's Green Claims Code and Australia's consumer protection framework similarly emphasize accuracy, evidence, clear comparisons and material limitations.⁷

Dedicated green claims rules are less common across Africa, but existing consumer protection laws still apply. South Africa's Consumer Protection Act and Nigeria's Federal Competition and Consumer Protection Act prohibit false, misleading or deceptive representations.⁸ Organizations should therefore consider the consumer, advertising, labelling, and sector rules that apply in each market. Although the legal details differ, the expectation is consistent: understand what the claim communicates, have the evidence to support it, and consider the overall impression it creates.

A more credible way to communicate

Organizations do not need perfect environmental performance before they communicate. They do need to be honest about the maturity of the work. A pilot can be described as a pilot. A target can be disclosed with its dependencies. An increase in emissions can be reported with an explanation and a corrective plan. Neither greenwashing nor greenhushing builds lasting trust. The more credible approach is transparency.

Use specific language

Broad claims place a heavy burden on evidence. “Environmentally friendly,” “sustainable” and “carbon neutral” can suggest more than the organization intends. A specific statement gives the reader something that can be understood and checked.

For example, “This product is environmentally friendly” says very little. A more useful statement would be: “The package contains 60% post-consumer recycled plastic by weight, based on supplier records for products manufactured in 2025.” The latter has a defined attribute, unit, evidence source, and period.

The same principle applies to greenhouse gas claims. “We are on track for net zero” should be replaced with current performance and the gap that remains. An organization could state: “Our Scope 1 and 2 emissions were 18% below the 2020 base year in 2025. Our 2030 target requires a 42% reduction. Two planned projects remain subject to capital approval.” This wording is less dramatic and more credible.

Keep evidence close to the claim

Each material environmental claim should have an evidence file. It does not need to be elaborate. It should contain the approved wording, calculation, source data, methodology, assumptions, boundary, relevant approvals, and any assurance statement. The file should also record where the claim appears so that later corrections can be made consistently. This is especially important when one result appears in several places. A statement prepared for a technical report may be shortened for a proposal, website, or social media post. Each shortened version should retain the qualifications that affect the overall meaning.

Use independent assurance where it matters

Independent third-party validation or verification can strengthen the credibility of environmental information and reduce the risk of unsupported claims. It provides an objective assessment of the evidence, methodologies, assumptions, and boundaries behind a claim. However, organizations should clearly state what was assessed, the criteria used, the reporting period, and the level of assurance. Verification of a GHG statement or a product carbon footprint certification, for example, does not automatically cover every environmental claim made by the organization.
