2° Lending (2DL) seeks to align banking with the Paris Climate Accord by making lending carbon neutral in North America and Europe by 2030. 2DL uses a collaborative innovation methodology - successful in sectors from solar to community investing - to bring banking representatives together to rapidly develop, test and scale climate solutions. We engage directly with banks, and through their influencers; pension funds, asset managers, anchor institutions, municipalities, insurance, consumers and civil society. 2DL has 4 initiative groups intervening across the banking system. Ultimately, we seek a diverse and decentralised banking system able to close the global climate finance gap of $25-30 trillion and keep temperature rises below 2°C.
