Five Ways Banks and Fintechs are Trying to Slow Climate Change

In the face of increasing public and regulatory pressure, the global financial sector is rapidly innovating to help curb the climate crisis. Discover five distinct ways banks and fintechs are working to slow climate change by embedding sustainability directly into their products and services, moving beyond mere public relations to tangible action.

One of the most direct and impactful methods is through specialized green lending programs.

Financial institutions, ranging from traditional banks like Fifth Third Bancorp to mission-driven entities like Clean Energy Credit Union, are actively offering tailored loans for everything from solar photovoltaic systems and geothermal heat pumps to general green home improvements. These products provide the essential capital needed for consumers and businesses to invest in personal clean energy infrastructure, which is a major focus following legislative measures like the Inflation Reduction Act.

A second major area of innovation is carbon footprint tracking tools.

Global payment companies like Visa and Mastercard, in partnership with sustainability software providers, are integrating features that analyze the estimated carbon impact of a consumer’s daily transactions. Fintechs like Klarna also offer this functionality, allowing users to see their carbon “score” and receive personalized insights on how to reduce their environmental impact, essentially nudging them toward more eco-conscious spending habits.

Thirdly, a new wave of green challenger banks and digital-only brands is emerging.

Institutions like Aspiration, Atmos Financial, and Greenpenny are building business models where customer deposits are explicitly routed to fund clean energy projects and simultaneously avoid supporting fossil fuel investments. They attract customers with competitive features like high-yield savings accounts, green mortgages, cash-back rewards for shopping at sustainable companies, and automated donations to climate charities.

Fourth, the ecosystem is being expanded through Fintech partnerships.

Companies like Ecolytiq and Carbon Zero Financial are shifting to a business-to-business (B2B) model, providing their proven climate-focused technology as a service to established financial institutions. This allows a broader range of banks to quickly implement features like carbon calculators, credit card point offsets, and sustainable product locators within their existing mobile apps, ensuring that green banking features become widely accessible to the mass market.

Finally, the concept of green Banking-as-a-Service (BaaS) is taking root. Climate-focused institutions, such as Climate First Bank with its OneEthos unit, are developing and white-labeling their proprietary green technology platforms to make it easier for other financial institutions to adopt and scale ESG principles. This includes providing the core technology for efficient green loan processing and dashboard systems that illustrate a customer’s emissions savings, accelerating the industry’s collective effort toward a sustainable future.
