1. 中国技术工作组的工作包括技术发展，把软件在中国适应（比如符合中国加密法的要求），翻译软件和教育资料，和协助应用者的开发。
2. 主要发展的技术是Fabric，有少数人用Indy和Cactus。
3. 主要应用的范围是企业，金融，和商务。
4. 由于现在禁止用代币（不可以用代币交换法币），应用的范围就只包括数据记录和企业合作。
5. 数据人民币现在只有在个人代替钞票应用，没有企业之间应用。
6. 现在中国国内对用区块链做碳交易有些兴趣，为了满足2030碳高峰，2060碳中和的目标。

下一步我们计划继续讨论：下一步我们会共同讨论：

• 碳交易：什么结构，怎么执行。
• 碳的计算标准和基本软件。
• 碳交易的应用。应用Cactus链接不同的区块链。碳的计算标准和

On May 25 at 10 AM Beijing time, Si Chen will introduce introduced the CA2SIG to the Hyperledger Technical Working Group China.  Topics of discussion will includeDuring this call we discussed:

1. General overview of the CA2SIG and the different working groups
2. Importance of climate as a global trade issue
3. Our Hyperledger Labs project for blockchain carbon accounting
4. Learn more about the TWG China, including their technical work and types of projects
5. Discuss possible areas of collaboration, including low-carbon and zero-carbon products in the supply chain and trade finance, and low-carbon green finance.

...

2. Greenhouse Gas Protocol for calculating company and product emissions
3. European Emissions Allowance trading scheme 

We also discussed the work of the Hyperledger Technical Working Group China and the current state of blockchain and climate in China:

1. The TWG China is currently involved in technical development, including adapting Hyperledger to local requirements such as China's Encryption Law, translation of the software and training materials, and assisting in implementations.
2. Currently the predominant use of Hyperledger in China is Fabric, with small number of users of Indy and Cactus.
3. Key use cases include enterprise collaboration, finance, and trade.
4. Partly due to the recent ban on cryptocurrencies in China, which extends to any token that can be exchanged for fiat money, the blockchain projects are focused on data collection and collaboration.  
5. The Central Bank Digital Currency, digital RMB, is currently only used as a substitute for cash by consumers and has not been used in any B2B applications. 
6.  Climate is becoming an issue of interest in China with the government's recent climate goals ("Peak carbon by 2030 and carbon neutrality by 2060").  There is discussion about carbon emissions allowances and trading and the possibility of the blockchain playing a role in such schemes.

We planned some follow up discussions around:

• How to implement carbon emissions trading using blockchain
• Standards and common reference open source software for calculating emissions
• Using Cactus to connect different blockchain networks.
