This article analyzes the communication of corporate social responsibility (CSR) and corporate image in the chemical industry through mission slogans. Morsing's (2006) CSR communication framework is adapted for a comparative analysis of the strategies behind mission slogans. By grouping rhetorical strategies in a mission slogan into a mission slogan functionality grid, it was found that most chemical companies use the mission slogan to share their value proposition (CSR promise) and to present their often-stigmatized activities in a euphemistic way. This article offers the tools to use mission slogans as lenses through which to analyze corporate image strategies. (Contains 4 table and 3 figures.)
