Do you compare ethical banks because you don't want your money to finance sectors that don't match your values? This comparison gives you practical answers, with user feedback, clear ranking, and concrete vigilance points to avoid bad surprises when choosing and opening the account.
Understanding what an ethical bank is
Ethical banks are based on social and environmental criteria that allow each customer to take concrete action through the use of their funds. They are distinguished by the exclusion of polluting sectors (coal, oil), the lack of funding for weapons or nuclear power, and the desire to support only projects with positive impact: renewable energy, organic farming, professional integration. A bank likeThe Nefpublishes an exhaustive list of its financing each year, whileHeliosoffers real-time monitoring via its application, allowing to see the real impact of supported projects. You can find their reports and analyses, but also the presentation of theFrench ethical banksto dig every position.
Origins and evolution of ethical banks
The model of ethical banks was born in the 1970s under the impetus of European social movements. The Nef (France) and GLS Bank (Germany) specify data, objectives and exclusions. The sector is being strengthened through the FEBEA, a European federation of about 30 alternative establishments, all committed to the exit of fossil investments, transparency and local action.
After each crisis, the interest of individuals in responsible alternatives is growing: in 2026, there are nearly 115 000 customers in France, 40 billion euros of assets and a continuous but still marginal growth against universal banks. New players like Green-Got or Bunq attract young customers by focusing on simplicity and direct impact.
Why choose an ethical bank?
To opt for an ethical bank is to choose transparency on the use of its funds. By supporting projects aligned with your beliefs, your money avoids financing controversial sectors and serves a social or ecological cause. Customers who have opened at Helios, Green-Got or La Nef highlight the ecological commitment and the sense of control over the impact of their savings. However, ethical banks can offer a more limited range of services (no premium card, few agencies, sometimes higher fees) and ask whether your actual needs are compatible with the offer.
Ranking and comparison of ethical banks in 2026
The ranking of ethical banks is based on transparency, the level of exclusion of polluting sectors, the practical services offered, and the real cost of each formula.

|---|---|---|---|---|---|
| The Nef | 100% public, exclusively dedicated to the social and solidarity economy | Savings, responsible credits, without current account | Variable by investment | Maximum commitment, total transparency | No current account, offer limited daily |
| Helios | Accurate digital tracking, 100% green investment | Current account, credit card and premium | From 6 € | Intuitive interface, investment traceability | Partial offer, monthly fee |
| Credit Cooperative | ESS focused, partly on renewable energy | Full range: current account, credit, savings | From 3.70 € | Serious institution, wide coverage | Less stringent investment criteria |
| Green-Got | Measured environmental impact, zero fossil | Digital accounts, ecoresponsible cards | From 6.90 € at 12.90 € | Ecological design, traceability | High rates for a neobank |
| Bunq | Tree planting per transaction | Accounts, maps, digital tools | From 2.90 € | Mix modernity/ecology | Less local ESS focus |

Green-Got or Bunq, more digital, are suitable for mobile users willing to accept fees for environmental traceability.
Criteria for choosing your ethical bank
- Transparency of funding: The ability to publish each funded project, such as La Nef or Helios, avoids ambiguity. Use Moralscore-type comparators to check the actual alignment between communication and acts.
- Accurate cost analysis: Compare the overall cost – subscription, withdrawals, foreign exchange payments, ceilings – to avoid the pitfalls of overly attractive offers.
- Services available: Depending on your usage, check the digital autonomy (Bunq, Helios), the range of products (credits, savings, cards), and compatibility with mobile management.

Benefits and limitations of ethical banks
- Strong social and environmental impact: rigorous project selection, accessible traceability.
- Transparency on investment flows: annual publications, reports, followed by app.
- Participation in governance (case of La Nef), giving voice to the client/co-saving.
- Fees perceived as high compared to conventional neobanks.
- Sometimes incomplete banking services, especially on international current accounts and premium offers.
- Limited local or national coverage (for La Nef), less suitable for large travellers.
Example: Helios Subscriber reports clear investments but raises monthly cost higher than a card « classic ».
A Crédit Coopératif user appreciates the ESS commitment on credits, but regrets the slow initial mobile app. These returns are frequent and call for proper weighting of each criterion before bank changes.
User opinions on ethical banks
Customer opinions converge on the idea that the choice of an ethical bank is based as much on conviction as on compromise, particularly with regard to mobile features, services and clarity of tariffs. Helios or Green-Got users are plebiscite the real ecological impact and traceability; those of La Nef value the cooperative model and total transparency. On Trustpilot and the advisory platforms, Helios reaches more than 4.5/5, but some deplore the lack of depth on the products or the young age of offer. Green-Got raises interest from those concerned about not supporting the fossil sector, while asking for more diversity on banking tools.
Opening an account in an ethical bank: steps and vigilance
The opening is most often done online, on application or web form. Prepare identification and proof of residence. The first payments are required to activate the savings or card. The Nef will require more documents, Helios or Green-Got allow a seamless digital route with instant transfer.
For day-to-day management (payment, withdrawals, credit), Crédit Coopératif remains the most versatile, while Bunq and Helios address mobile users with limited needs. Think about checking each card's fee schedules and ceilings before validating your opening, to avoid unexpected charges outside the euro area. See also sectionOpen an online account.
