liu xuezhi, director of the low-carbon economics and management research center of beijing university of chemical technology, stated: “of the top 20 enterprises listed in 2019, 10 are based in shanghai and 10 in shenzhen, with all but one being engaged in the primary and secondary industries. like 2018, 10 of the top 20 enterprises were rated four and a half-star, a leading level of environmental information disclosure, and the remaining 10 rated four-star. fosun pharma is the only one that ranks top 20 for eight years in a row.” liu also expressed his expectation that the report would raise the overall level of environmental information disclosure by listed companies in china, and push more listed companies to timely release environmental responsibility information reports and keep improving the environmental information disclosure system and content, thus playing a good example and leading role in society as a whole.
