The issue of greenwashing vs green hushing is becoming increasingly prevalent as organisations seek to communicate sustainability progress responsibly while ensuring their sustainability and environmental claims are properly evidenced.
The world of sustainability is getting more complicated and harder for organisations to navigate. Regulations are changing, expectations from stakeholders are increasing and businesses are being required to provide more detailed proof behind any environmental, social, or governance (ESG) claims they make. This creates a difficult question for many organisations: what do we say and what do we not say?
No organisation wants to be accused of greenwashing, particularly when the intention behind its sustainability work is genuine. However, the quieter choice is not always the safer choice. We believe that if an organisation is making tangible progress and has the evidence or verification to support that progress, it is better to communicate that progress responsibly rather than not at all.
While these challenges appear very different, they often stem from the same issue: uncertainty about how to communicate sustainability activity accurately and confidently. Thus, creating the greenwashing vs green hushing challenge.
The solution is not to make bigger claims, nor is it to remain silent. The most effective approach lies somewhere in the middle, where organisations can communicate genuine progress that is supported by evidence, transparency and verification.
Although the terms are often discussed separately, greenwashing and green hushing represent two ends of the same spectrum.
Greenwashing occurs when organisations make environmental or social claims that go beyond what can be supported by evidence. This may involve broad statements, selective reporting, vague terminology or claims that fail to reflect the full picture.
Green hushing, on the other hand, occurs when organisations choose not to communicate sustainability progress at all. This is often driven by concerns about scrutiny, uncertainty around regulations, or fears of being accused of greenwashing.
Greenwashing is saying too much without sufficient evidence.
Green hushing is saying too little despite having progress to share.
| Area of Impact | Greenwashing | Green Hushing |
| Stakeholder trust | Can reduce trust if claims are found to be exaggerated, vague or unsupported. | Can limit trust because stakeholders may not see the progress being made. |
| Reputation | Creates reputational risk if an organisation appears to overstate its sustainability credentials. | Can make an organisation appear inactive, even when meaningful work is taking place. |
| Compliance and Scrutiny | May increase the risk of challenge from regulators, customers, investors or procurement teams. | May reduce immediate scrutiny but can leave organisations underprepared for future disclosure expectations. |
| Commercial opportunities | Unsupported claims may weaken tender responses or customer confidence if evidence is requested. | Genuine progress may be overlooked in tenders, procurement processes or stakeholder conversations. |
| Internal engagement | Employees may lose confidence if public claims do not reflect internal reality. | Employees may feel positive work is undervalued or invisible. |
| Progress and accountability | Overclaiming can create a false sense of achievement, slowing meaningful improvement. | Under communicating can reduce momentum, recognition and accountability for continued progress. |
| Stakeholder understanding | Broad or unclear claims can confuse stakeholders about what has actually been achieved. | Lack of communication can leave stakeholders unaware of the organisation's commitments, actions or future plans. |
The sustainability landscape has evolved significantly in recent years because frameworks such as the Green Claims Code, CSRD, ESG reporting requirements and disclosure expectations across different sectors have increased the focus on transparency and accountability. Equally, public awareness of environmental and social issues has grown, meaning sustainability claims are receiving greater attention than ever before.
Marketing teams may want to showcase progress in internal and external communications
Sustainability specialists may have data but be unsure how it should be communicated externally
Leadership teams may recognise the importance of sustainability but worry about reputational risk if claims are challenged
This means that organisations often either overstate their achievements or avoid discussing them altogether.
Greenwashing can certainly damage trust for many reasons, for example, customers, investors, employees and regulators increasingly expect organisations to substantiate sustainability claims, if claims are found to be misleading or unsupported, the reputational consequences can be significant. However, green hushing also creates challenges.
Many organisations are undertaking sustainability initiatives, investing in carbon reduction, improving supply chain practices, supporting biodiversity projects or creating positive social impact within their communities. When these efforts are not communicated, stakeholders may never understand the progress being made.
Build stakeholder confidence
Strengthen tender submissions
Demonstrate leadership within a sector
Inspire positive action across supply chains
Attract environmentally conscious customers and employees
The goal should not be to avoid communication, but rather to communicate responsibly.
The most effective way to avoid both greenwashing and green hushing is to build communications around evidence. Evidence provides confidence by allowing organisations to communicate progress clearly while reducing the risk of overstating achievements.
"We are an environmentally friendly business."
"We have completed a carbon footprint assessment and are using the results to reduce emissions across our operations."
The second statement is more specific, more transparent and easier to substantiate.
Life Cycle Assessments (LCAs)
Business Carbon Assessments (BCAs)
Social value reporting
Independent certifications
The stronger the evidence base, the easier it becomes to communicate sustainability progress with confidence.
While data plays an essential role, not every outcome can be captured in a spreadsheet.
Many responsible business initiatives create wider environmental, operational and social benefits that are difficult to quantify directly.
Employee wellbeing initiatives may improve workplace culture.
Community programmes may strengthen local relationships.
Biodiversity projects may encourage greater environmental awareness among staff and stakeholders.
Volunteering initiatives may generate social value that extends beyond measurable outputs.
This is where storytelling becomes important. Data helps demonstrate that action has taken place, while storytelling helps explain why that action matters and what impact it has created.
The strongest sustainability communication combines both approaches. Evidence provides credibility, while stories help bring that impact to life.
Start by reviewing your website, marketing materials, tender responses and social media content.
Can we evidence it?
Would an external stakeholder understand exactly what we mean?
Avoid broad statements wherever possible.
Instead of claiming to be "sustainable" or "green", explain the specific actions, improvements or commitments that support those statements.
Assessments such as carbon footprints, LCAs and biodiversity footprinting provide organisations with a clearer understanding of their impacts and opportunities for improvement.
Without a baseline, it can be difficult to demonstrate progress over time.
Stakeholders do not expect perfection.
Many organisations are at different stages of their sustainability journey. Communicating progress honestly often builds more trust than making ambitious claims that cannot be substantiated.
Third-party accreditation and verification can help strengthen credibility and stakeholder confidence.
Independent review provides assurance that claims are supported by evidence and assessed against recognised criteria.
The debate around greenwashing vs green hushing is not about choosing one risk over the other. It is about finding the right balance between communication and credibility.
Organisations should feel confident sharing genuine progress, provided that progress is supported by evidence and communicated transparently.
The most effective sustainability communication is neither exaggerated nor silent. It is unambiguous, proportionate, evidence-based and honest about both achievements and ongoing challenges. In turn, building trust within your sustainability communications.
