The sdEffect is an initiative aimed at promoting sustainable development (SD) considerations in investment decision-making by expressing in financial language the effect of corporate SD practices on share price and company valuations. Published in February 2006, Translating Sustainable Development into Financial Valuation Measures is a pilot analytical framework aimed at helping companies and their executives to assess, measure, and isolate the financial value implications of their SD practices and to communicate these both internally and externally in financial language. It is also geared toward helping investors and the broader financial community to appreciate the additive value of SD and how specific SD activities can influence corporate financial valuations.
