The purpose of this paper is to examine the quality of carbon information disclosure in the listed companies in China. In addition to analyze the disclosures made by three Chinese listed companies to the 2009 Carbon Disclosure Projects (Only these three companies' information is publicly available), the paper also analyzes the carbon information disclosure of 70 listed companies from different industries in the Shanghai Securities Exchange. The effective laws, regulations and guidelines related to the environmental information disclosure are examined as well. The findings are as follows. Firstly, how to disclose the carbon information is seldom considered in the effective laws, regulations and guidelines. Secondly, the meaningful information is not fully disclosed. Thirdly, there is inconsistent as far as how companies address this subject in their filings of annual reports, social responsibility reports, sustainable development reports and CDP questionnaires is concerned. The practical implication is that the majority of listed companies in China do not voluntarily disclose carbon information makes it difficult for stakeholders to assess how the companies will be affected by risks related to climate change. Therefore, regulatory authorities should clarify the application of existing law to the disclosure of carbon information, the development of mandatory disclosure standards at the corporate level should be considered, and it is necessary for companies to develop carbon reduction strategy and realize the importance of carbon information disclosure.
