Green bonds are a kind of financing bond instruments that specifically use funds to meet green projects. The specificity of green bonds compared with general bonds is mainly manifested in the use of green projects；the evaluation process reflects the greenness，the specialty of fundraising tracking management and the specialty of annual reports. At present，the development of Beijing’s green bonds still has problems such as slow market size growth，relatively single issuers of green bonds，inconsistent green bond market standards，and differences in third-party assessment and certification methods. It is recommended to further promote the implementation of preferential policies for green bonds，provide financial support for green bonds，establish independent third-party green certification agencies，and enhance the awareness of green investors.
