Trialogue was founded by Nick and Vanessa Rockey, and Rob Worthington-Smith in 1999. The early years saw the development of publications and services previously run by the founding team, including the CSI Handbook. Work in the sustainability field began with the development of a Corporate Citizenship Management Rating (CCMR), in partnership with the African Institute of Corporate Citizenship. We wrote our first sustainability report for the National Port Authority in 2001 and in 2004 Trialogue published its first handbook on corporate sustainability, titled The Good Corporate Citizen.
Soon after we made a decision to focus the business entirely on corporate responsibility and since then have tested and launched many new products, including an Environmental Handbook, a Social Map and the Trialogue CSI Conference, now an established annual event. The business continues to evolve by extending and refining its range of products and services within the fields of corporate sustainability and corporate social investment (CSI).
