From the perspective of corporate risk communication, this study explored the corporate websites how to communicate the environmental message and social responsibility information. A total of 447 corporate websites in 2016 were content analyzed. The study found that 278 corporate websites presented the environment message. Corporate websites liked to present the theme of "climate change" of environmental message. The stakeholder mainly mentioned in the environmental message was "Employee". The background colors of corporate websites were based on green and blue. Most of corporate websites were able to illustrate the "has done" message of corporate environmental protection behavior. The rhetoric analysis pointed out that commercial rhetoric is no longer the main discourse on corporate websites. Corporate websites liked to use "numbers" & "evidence" rhetoric, "advocacy" rhetoric, and "competition" rhetoric to show their active behavior of protecting environment. Corporate websites adopted the color symbols to reflect the Utopia narrative of "seeing is believing", and also used the "sustainability" and "mission" rhetoric to construct corporate environmental responsibility.
