The 2023 United Nations Climate Change Conference (COP28) in Dubai witnessed significant contributions from blockchain and crypto projects aimed at combating climate change.

Various blockchain initiatives were launched, focusing on transforming waste management and tracking carbon emissions, demonstrating the technology's potential in environmental efforts.

Key developments included a collaboration between Envision Blockchain and the HBAR Foundation with the UN to create a decentralised platform for carbon market digitisation and verification.

Allcot IO, the Carbon Opportunities Fund, and Tolam Earth announced a partnership to create digital carbon credits using the Guardian open-source platform on Hedera’s network.

Post-COP28, DLT Earth plans a hackathon event to develop digital climate methodologies, emphasising transparency in climate market assessments through collaboration with the DLT Science Foundation.
