  -This repository contains the code for the [Hyperledger Carbon Accounting and Neutrality Working Group](https://wiki.hyperledger.org/display/CASIG/Carbon+Accounting+and+Certification+Working+Group). Each
  -sub-folder is for a different project of the Working Group and has its own code and instructions:
  +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](lib/README.md): Common library of code
  - [fabric](fabric/README.md): [Emissions Data Channel](https://wiki.hyperledger.org/display/CASIG/Emissions+Data+Channel)
