Regenerative Finance (ReFi) and Green Crypto Initiatives

ReFi is a movement within Web3 focused on using blockchain and decentralized tools to heal and regenerate the planet. Unlike traditional finance, which often extracts value, ReFi aims to create net-positive environmental and social impacts —think of it as DeFi with an eco-conscious mission.

ReFi protocols often fund:

Carbon capture and carbon credits

Reforestation and land regeneration

Ocean cleanup or biodiversity restoration

Climate-positive infrastructure

Environmental DAOs and community-driven green efforts
