When Green Payment Card Fail

The premise of Green / Eco-friendly payment cards is that they make climate action feel effortless and seamless. Simply by spending as you go about your day as usual, you can plant a tree, offset carbon by funding a project, etc.

It’s a compelling proposition especially in a world where most people are more concerned about the environment (A 2025 Globascan survey found that 49% of Americans bought a green product in the last month). And so, over the last several years, fintech (mostly) across different markets have brought this to life - launched cards tied to tree planting, carbon offsetting, waste reduction (by using greener materials) and conscious carbon tracking.

For the brands, the cards are a product that stand out from the norm while giving their customers a way to align their daily habits with their beliefs and passions. It’s a pretty neat idea. In practice though, it’s of course more nuanced. Several such cards never gained enough traction. Let’s examine some such cards and theories about why they might have failed.

The cards that tried

Aspiration Zero in the US was a credit card that was positioned as helping cardholders fight climate change through everyday spend. Aspiration would plant a tree with every purchase and allow cardholders to round up purchases to plant more trees. The physical card was also made from plant-based materials rather than plastic. The Zero card was since transitioned to GreenFi, and then discontinued as GreenFi chose to focus on green checking account, investing and the GreenFi debit card.

Similarly, Treecard debit card in Europe and the US offered to fund tree planting - every $60 spent meant one tree planting. Treecard claimed that 80% of its profits went to reforestation. It also made the physical card out of cherry wood, very on brand. After discontinuing the card, Treecard focused on nudging behaviours through its app - providing rewards for activities, experiences, and purchases from sustainable merchants in its marketplace.

Meanwhile, in Canada, MogoCard was a prepaid card that initially offered one pound of CO2 to be offset for every dollar spend on the card. Its proposition later changed to a tree planted for each purchase. In a different angle than Aspiration Zero and Treecard, MogoCard also had spending controls and cash back as prominent features in some versions of its proposition. Mogo has since discontinued the card and is focusing on its personal loan proposition.

Finally, in the UK, the Zero debit card combined a 95% recycled plastic card with a GreenScore to help cardholders track their carbon footprint, and ethical investing. Its aim was to make climate visibility a core part of personal finance, with that visibility accessible via its app. The fintech ceased trading this year.

Why they failed

Overall, these cards approached their eco-friendly proposition through tree planting, carbon offsetting, greener card materials, behavioural nudges and carbon footprint visibility. But despite the emotional resonance of these propositions, some are hard to validate and others are expensive to maintain. These reasons lie at the heart of why they so often fail.

Credibility:

Probably the most damaging reason, but credibility can collapse when the environmental claims made can’t be proved. Greenwashing risks, always hovering in any environmental endeavour, becomes real.

This was most clearly exposed in Aspiration’s case. This 2021 article by ProPublica unabashedly stated that Aspiration’s ‘marketing is greener than its reality’. It was revealed that the company made bold claims - overblowing the number of trees it had planted, as well as the number of its members. The way round-up contributions were used and the extent of fees that went to administrative costs (e.g., a massive marketing budget) rather than tree planting were also disputed.

Unfortunately, any green proposition that has its credibility called into question falls to pieces, whether or not it’s a card. This environmental benefit is closely tied to the emotions of users, and that’s what makes greenwashing (or even just the perception of greenwashing) so dangerous for any eco product.

Card economics:

Treecard’s closure message is candid on this. In 2023, they announced they were closing the debit card to focus on advancing their impact faster via other products - notably their app experience. This shows that the product (the debit card) that was most closely associated with their mission was actually not sufficiently funding that mission.

But Treecard hasn’t given up on the payment card proposition. Their website invites people to indicate whether they would be open to using a credit card product. This hints a fact that it’s much harder to sustain generous impact propositions with a debit card.

This isn’t surprising because debit cards generally have thinner economics than credit cards. Their interchange (a key revenue source for card issuers) is capped in many regions. So expecting such thin margins to fund mission statements may be largely unrealistic. It becomes too expensive.

Mogo’s story may be similar but admittedly less obvious. The prepaid card was discontinued in 2023 after the fintech explored several propositions. Prepaid cards have better interchange economics than debit cards in Canada. But given the proposition changes Mogo went through, we can infer that they were searching for a more durable formula to justify the cost of the environmental promise…which they didn’t find.

Top of Wallet Challenges:

A payment card is top of wallet when its the card that a user instinctively reaches for to make any payment. A typical user will default to their most rewarding, familiar, or easiest-to-manage card. Every card issuer reaches for this idea - to be a top of wallet card. And so a green card could have a great proposition but still fail if the cardholder doesn’t use the card enough. To drive long-term primary usage, the green card must compete with other more general cards in the market, and already in the user’s wallet.

This is where a green credit card might actually have a leg up over a debit or prepaid card - there are just more margins to play with to offer competing rewards (e.g., cash back), benefits (e.g. insurance) and experiences (e.g., a great app experience to manage the card). This is critical because the green card must have enough transaction volumes to keep it profitable and ensure that the impact model works long-term.

Arguably, Zero’s shut down in March 2026 is an outcome of such a challenge. The fintech ceased trading after failing to secure additional capital. This might have been because its primary product, the checking account and debit card, was not working economically.

This top of wallet challenge is especially unique. A green card is currently, by default, still a niche product. But a payment card that is niche cannot survive as it needs to have enough transaction volume to justify costs (which are already under pressure).

For it to work, the card needs to attract attention and be remain attractive enough for cardholders to use it every day.

Learn from their mistakes

Despite how it might seem above, green cards do have a place in payments. But the eco-friendly proposition cannot be a substitute for product strength.

First, the environmental promise needs to be credible, measurable, communicated accurately and truthfully, and able to stand up to scrutiny. This is non-negotiable.

Second, the card proposition, not just the environmental impact, but be good enough. The card must be able to compete with any other card in the market with regards to rewards, benefits, user experience, etc. And be applicable to any payment use case and user (not be a niche card). But this means that the card could inherently be more expensive because of that additional impact promise.

Third, the above implies that the issuer needs to be realistic about the product economics. If the card itself cannot fund the impact promise, then other revenue-generating wrappers or value-added services need to be incorporated into the business model. For example, GreenFI still has its green debit card but its rich rewards are centred around cash back when cardholders shop from sustainable merchants in its marketplace.

In conclusion, Green cards can work. But issuers need to explore different business models. Or potentially simply embed the mission statement into mainstream card propositions where they are features rather than standalone gestures.
