The document reports on a study of how 251 top European companies communicate about corporate social responsibility (CSR). It analyzes CSR communications through corporate reports, websites, advertising, and social media. Interviews with CSR experts from the companies explored perceptions of risks and opportunities of CSR communication. The study found that the most commonly communicated CSR issues were human rights, community involvement, and environmental protection. Social media use for CSR was limited, with only 5% using blogs. Experts viewed CSR communication as an opportunity rather than a risk if internal practices match external messages. Companies were advised to have a holistic CSR approach rather than focusing solely on marketing.
