Commercial banks should develop carbon finance, but there are more risks in the development process. In response to these risks, we can take the following measures. First, we can establish and improve the legal system to avoid legal risk. Secondly, we can formulate a stable policy regime to reduce policy risk. Third, we can build a sound internal control system to manage and control operating risk. Fourth, we can develop multi-channel training professionals to solve talent risk. Finally, we can establish and improve the carbon finance market to reduce market risk.
