Finance has enormous influence over where money flows, and a growing group of fintech companies is using that influence to support climate action and sustainability. From ethical banks to carbon-accounting platforms, green fintech combines digital financial services with environmental goals. This guide explains what sustainable finance means, why it matters, and profiles notable green finance and climate fintech companies around the world.
What is green finance?
Green finance (or sustainable finance) means directing money toward activities that benefit the environment and society, and away from those that harm them. It covers:
- Ethical and sustainable banking: banks that only lend to sustainable projects or avoid fossil fuels.
- Green investing: funds and platforms that invest in renewable energy and climate solutions.
- Carbon accounting and climate data: tools that measure and report emissions.
- Carbon removal and offsetting: platforms that fund verified climate projects.
- ESG reporting: environmental, social and governance data for investors and regulators.
Why sustainability in finance matters
- Capital allocation: banks and investors decide which projects get funded.
- Regulation: disclosure rules for climate risk and emissions are expanding in many regions.
- Customer demand: consumers and employees increasingly prefer sustainable providers.
- Risk management: climate change creates financial risks for loans and investments.

Challenges for green fintech
- Greenwashing: claims must be backed by transparent, verifiable data.

- Regulation: sustainability disclosure rules differ between regions and change frequently.
- Business sustainability: some green fintech start-ups have struggled to build profitable models, so due diligence matters before partnering or investing.
