As the climate crisis accelerates, quixotic tech solutions are being sought to capture emissions and geoengineer the biosphere. Yet existing technologies like blockchain already present an opportunity to drastically reduce emissions. With blockchain energy consumption a trending topic, it’s important to consider the value of open-source and decentralized technologies as climate solutions available today. This panel will explore viable blockchain sustainability use cases, including supply chain efficiencies, renewable energy certification, utilizing NFTs to inspire people to commit to individual climate action, how to decarbonize the blockchain space, and how incentivization structures of blockchain can change wealth distribution to align with preserving natural spaces and common resources.
