It has become a possibility and trend to find a trickle of news in big data. Environmental risk information concerning the public interest is often over-dispersed，complex and too professional，so it is rarely paid attention to by the public or revealed by the media. NBD（National Business Daily of China）has been working with IPE（Institute of Public and Environmental Affairs）to tap into China’s complex environmental risk data. The resulting “A-Share Green Report” project is based on continuously updated government open big data，from the perspective of public company environmental responsibility and information disclosure，and use AI + Writing to continuously produce various types of supervision in the batches of News reports. This project has pioneered a new model for mining news through dynamic data. Now the project has been running for nearly a year，and the experience and challenges encountered in the process can be discussed by the industry and academia.
