Firstly, blockchain technology can be applied to the trading of carbon emissions rights. By using a decentralized approach for registering, trading, and settling carbon emissions rights, blockchain can enhance transaction transparency, reduce transaction costs, and thereby promote the effective circulation of carbon emissions rights and the realization of emission reduction targets. Secondly, blockchain technology can be applied to data monitoring and governance in the environmental protection field. By constructing an environmental data monitoring system based on blockchain, real-time collection, storage, and analysis of environmental data can be achieved, ensuring the authenticity and credibility of the data. Meanwhile, blockchain technology can also be applied to financing  and investment in the environmental protection industry. For example, green bonds or environmental project tokens can be issued through blockchain."}]}],"pr":"727834f243524e7d47c9da7f5069a116da1011784880539f3d2ff2e0730d569c"}
