Sustainable investing has surged in popularity as investors increasingly seek to align their portfolios with environmental and social values. With growing awareness of the climate crisis and the urgent need to reduce global emissions, financial institutions and asset managers are offering a wide range of sustainable investment products.
What was once a niche approach has now become mainstream, with sustainability considerations influencing capital allocation across asset classes, geographies, and investor profiles.
However, this rise in sustainable finance has also brought challenges – most notably, the risk of greenwashing. But what does greenwashing mean in sustainable investing, and why should investors be vigilant?
Greenwashing occurs when a company, fund, or financial institution misleads investors into believing its products or operations are more environmentally friendly than they truly are.
In sustainable investing, this often means a fund is marketed as ‘ESG’, ‘green’, ‘eco-conscious’, or ‘impact-driven’, yet its actual practices, holdings, or policies don’t meaningfully support environmental goals. In other words, the sustainability label is more of a marketing tactic than a real commitment.
Crucially, greenwashing is not always the result of deliberate deception. In many cases, it stems from weak data, inconsistent standards, or an over-reliance on narrative-driven reporting rather than environmental evidence.
How Does Greenwashing Happen in Sustainable Investing?
Greenwashing occurs in various ways within sustainable investment products, often through vague or unsubstantiated claims that lack transparency or clear evidence.
These practices typically emerge where sustainability goals are loosely defined, verification mechanisms are absent, or disclosure focuses on intent rather than outcomes.
Vague or Unsupported Sustainability Claims
One common greenwashing tactic is the use of broad, ambiguous language around sustainability objectives without concrete data or measurable outcomes. For example, funds may claim to support ‘environmentally friendly’ companies or ‘positive impact’ without specifying how they assess or verify these claims.
Such vague sustainability claims can mislead investors about the true environmental benefits of their investment.
Without clear metrics, baseline data, or ongoing monitoring, these claims are difficult to challenge and easy to overstate – particularly in investment markets.
ESG Funds Holding Environmentally Harmful Companies
Some ESG (Environmental, Social, and Governance) funds include companies with significant carbon footprints or poor environmental practices, despite marketing themselves as sustainable. This mismatch between a fund’s sustainability focus and its actual holdings can result from a lack of rigorous screening criteria or prioritising financial returns over sustainability goals.
This disconnect weakens the integrity of ESG classification, creating a gap between sustainability claims and the underlying environmental impact of the investments themselves.
In some cases, funds justify these inclusions through broad ESG interpretations or transition narratives that lack clear timeframes, accountability, or evidence of improvement.
Lack of Clear Screening Criteria
Without clear sustainability objectives and transparent screening processes, investment funds may include companies that do not meet robust environmental standards. This lack of clarity in ESG considerations and sustainability disclosure requirements makes it difficult for investors to evaluate the genuine sustainability impact of their investments.
United Nations-affiliated bodies such as UNEP Finance Initiative and European regulators have highlighted how inconsistent, incomplete, and hard-to-compare ESG disclosures increase greenwashing risk by obscuring real environmental impact.
Overstated Impact
Firms may overstate their environmental impact by claiming carbon neutrality or significant emissions reductions without credible evidence. This often stems from selective reporting or the use of incomplete data, distorting the true sustainability credentials of the investment and increasing the risk of greenwashing.
This is particularly problematic when offsets, estimations, or future commitments are presented as achieved outcomes, blurring the line between ambition and reality.
Misleading Ratings or Certifications
Greenwashing also happens when funds rely on third-party ratings or certifications that may not be rigorous or fully transparent. Misleading ratings can give a false sense of security to investors, masking sustainability problems or unsubstantiated claims about a company’s operations or environmental benefits.
Not all ESG ratings are created equal, and investors should scrutinise the methodologies behind these ratings to avoid being misled. Significant variation between ESG rating providers means the same company can receive vastly different scores, further complicating decision-making and comparability.
Why is Greenwashing a Problem?
Greenwashing poses serious challenges for investors and the broader sustainable finance market.
It Misleads Investors
Misleading environmental claims and false advertising can cause investors to put their money into funds that do not align with their sustainability values or contribute meaningfully to tackling climate change.
This undermines investment decision-making based on accurate ESG data and sustainability credentials. Greenwashing can distort investment decisions, leading to portfolios that do not reflect investors’ true sustainability preferences.
Over time, this misallocation of capital reduces the effectiveness of sustainable finance as a driver of real-world change.
It Undermines Trust
When greenwashing accusations surface, they erode trust in sustainable investment products and the financial institutions promoting them. This loss of confidence can slow the growth of responsible investing and reduce the willingness of investors to support sustainability initiatives.
International organisations and regulators, including UN-affiliated bodies and European supervisory authorities, have warned that greenwashing damages the credibility of sustainability efforts and discourages participation in sustainable finance. Trust, once lost, is difficult to rebuild.
It Slows Real Environmental Progress
By diverting capital away from genuinely sustainable companies and projects, greenwashing slows progress toward achieving net-zero carbon emissions and other sustainable development goals.
It creates a false impression of progress while global emissions continue to rise. Greenwashing can delay meaningful climate action by masking the true scale of environmental challenges.
This gap between perceived progress and actual outcomes risks normalising underperformance rather than driving improvement.
It Creates Regulatory Risk
Greenwashing exposes asset managers and investment funds to regulatory scrutiny and potential penalties, especially as regulatory bodies like the European Union introduce stricter sustainability disclosure requirements and anti-greenwashing rules, this includes Sustainable Financial Disclosure Regulation (SFDR)product disclosures, Corporate Sustainability Reporting Directive (CSRD)corporate reporting requirements, and regulatory guidance from European supervisors on the use of ESG and sustainability terms in fund names.
As enforcement increases, organisations without robust, verifiable sustainability data could face growing legal and reputational exposure.
How to Spot Greenwashing as an Investor
Investors can take proactive steps to avoid greenwashing and make informed decisions aligned with their sustainability goals.
A key starting point is clarity: credible, sustainable investment funds should rely on transparent methodologies, clearly defined ESG criteria, and measurable impact metrics.
Without this foundation, sustainable claims are difficult to verify.
Examine the Fund’s Holdings
Review the companies included in the investment fund to ensure they align with your sustainability objectives. Look out for holdings in industries with high carbon emissions or poor environmental practices that contradict the fund’s sustainability claims.
Transparency at the holding level is often more revealing than high-level ESG labels.
Check Third-Party Verification
Look for independent verification of the fund’s sustainability claims through credible third-party certifications. For investment funds, this usually means audited sustainability disclosures or independent assurance.
Certifications such as the FSC Certificationor carbon-neutral standards may also be relevant when assessing the sustainability claims of underlying products or portfolio companies.
Review Engagement & Voting Policies
Consider how actively the fund engages with the companies it invests in on sustainability issues. Funds that use their voting rights to encourage responsible business practices demonstrate a stronger commitment to environmental and social progress.
Active stewardship signals intent – but should be supported by measurable results.
Assess the Fund’s Impact Reporting
Look for detailed, transparent impact reporting that quantifies the fund’s environmental benefits, such as reductions in carbon footprint or greenhouse gas emissions. Avoid funds that provide vague or unsubstantiated claims without supporting data.
Why Greenwashing is Becoming More Common
Greenwashing is becoming more common because sustainable investing has expanded faster than the verification infrastructure has evolved. As ESG-labelled products proliferate, many organisations are expected to demonstrate sustainability performance without access to consistent data, standardised frameworks, or reliable verification systems.
This structural gap is reflected in recent market trends. Reuters reported that climate-related greenwashing incidents linked to banks and financial services companies increased by around 70% year-on-year, reflecting rising scrutiny of sustainability claims in the sector.
Sustainability disclosures often rely on self-reported, retrospective data, making it difficult to assess accuracy, comparability, or material impact. In the absence of shared standards, sustainability becomes open to interpretation rather than evaluation.
At the same time, reporting requirements have become increasingly complex. Lengthy reports, fragmented metrics, and selective narratives can obscure material information, allowing weak performance to appear credible.
In this environment, greenwashing does not always look like false claims – it often looks like incomplete truth.
Introducing TIMBERCARD
TIMBERCARD is a wooden payment card designed to offer a more credible alternative to conventional plastic cards within financial services. As greenwashing becomes more common in sustainable finance, the need for sustainability claims that are directly tied to the physical products being issued has never been greater.
Unlike traditional payment cards, TIMBERCARD’s card body is produced using FSC-certifiedwood, reducing reliance on fossil-fuel-based plastics. Its material composition is visible, tangible, and easy to understand, removing ambiguity around what the card is made from and how it differs from conventional alternatives. This clarity helps financial institutions communicate sustainability credentials more honestly, without relying on vague or overstated environmental claims.
Product-level transparency matters. Being flustix LESS PLASTICS | PRODUCT certified, TIMBERCARD’s card body is verified as at least 99.25% plastic-free. This enables issuers to align sustainability messaging with a real, material change in the card itself, supporting clear communication and reducing the risk of misleading claims.
For banks and card issuers seeking to strengthen trust and demonstrate genuine material change, TIMBERCARD presents a practical step forward. By embedding sustainability into the physical product – not just the narrative around it – TIMBERCARD helps support more responsible card issuing and more credible sustainability commitments.
