Expected Contribution From Index

The index provides competitive advantage to Turkish companies managing their corporate risks and opportunities effectively. An investible index on which new instruments can be developed is in place to attract capital for companies. The Index reflects companies’ approach to important sustainability issues including global warming, draining of natural resources, health, security and employment, while allowing an independent assessment of their operations and decisions regarding these issues.

The Index offers companies the opportunity to compare their sustainability performance on both local and global level. With the Index, Borsa İstanbul provides companies an instrument for evaluating their performance and consequently adopting new targets for further improving their performance while allowing them to develop their risk management abilities for corporate transparency, accountability and sustainability. This, in turn, allows companies to gain a competitive edge. Inclusion in the Index adds to their visibility and prestige.

For companies, the Index facilitates the access to global clients, capital, and lower-cost finance. The project aims to create an instrument which allows investors to select and invest in companies that adopt principles of sustainability and corporate governance. Today, responsible investment is preferred mainly by institutional investors. BIST Sustainability Index encourages founding such funds, while facilitating for Index-constituent companies to get a larger share from such funds. At the same time, the Index offers a new financial asset category for all investors.
