This project uses web3/blockchain/distributed ledger to solve several key challenges for climate change:

• Storing data from energy use, renewable energy production, carbon removal or reduction projects in a permissioned data ledger.
• Tokenizing emissions audits, carbon credits, and energy attribute certificates.
• Validating climate projects by voting through a Distributed Autonomous Organization (DAO).

With it you could implement a variety of use cases, such as developing and monetizing carbon emissions reductions projects; emissions calculations for individuals, companies, and supply chains; and using carbon credits to implement emissions reduction plans.

The code is divided into the following components:

• lib: Common library of code
• fabric: Emissions Data Channel
• hardhat: Net Emissions Token Network and Climate DAO
• app: Applications built on these components, including React user interface and supply chain emissions calculations.
• open-offsets-directory: Voluntary Carbon Offsets Directory
• secure-identities: Support for signing transactions using Vault or web-socket
• supply-chain: Supply Chain Decarbonization
• data: Data for setting up the applications

To try it out, use the demo at emissions-test.opentaps.org or follow the steps in Getting Started to set it up yourself.

For more details, see the

• User's Guide
• Open Source Carbon Accounting video
• Hyperledger Carbon Accounting and Neutrality Working Group
• Setup Guide and documentation in each component.
