When we think of climate change fighting tech, the first thing that might come to mind is solar panels or electric cars. But, technology in the financial sector could play a serious role in mitigating the worst of climate change. Enter financial technology, or fintech,— a growing section of financial services that utilizing algorithms, data gateways, and artificial intelligence helps customers and business partners handle different business transitions.
The financial sector is powerful—top banks are worth hundreds of billions of dollars alone— servicing everyday people in need of bank accounts and large companies as well. But the financial sector was built to build profits even if that means getting involved in risky investments like fossil fuel projects. But to mitigate climate change in time, taking money out of high-emitting projects is likely necessary.
