Approaches to Sustainable Investing

Approaches to Sustainable Investing

We understand today, better than ever before, how ESG considerations can impact risk and return. Climate change is the clearest and most pressing illustration of this urgent reality. At MSCI, we believe ESG & Climate factors will significantly impact the pricing of financial asset and the risk and return of investments, which will lead to a large-scale re-allocation of capital over the coming years.

Research has identified examples of meaningful links between ESG and financial performance, demonstrating that ESG affected the valuation and performance of companies.(1)


Given the significant and increasing impact that we expect ESG to exert on assets and the allocation of capital, MSCI urges all investors to integrate ESG considerations throughout their investment processes: To identify new investment opportunities, manage emerging risks and achieve long-term, sustainable investment performance..

To support this drive, we have developed the MSCI Principles of Sustainable Investing, which sets forth our views and recommendations on the core principles and best practices for ESG integration by investors globally.


Interaction between MSCI ESG Research and the companies and fixed income issuers we rate continues to expand at a rapid pace.

    Investment Strategy- Asset owners should integrate ESG considerations into their processes for establishing, monitoring and revising their overall investment strategy and asset allocation.


    Portfolio management- Portfolio managers should incorporate ESG throughout the entire portfolio management process, including security selection, portfolio construction, risk management, performance attribution and client reporting.


    Investment Research- Research analysts assessing companies and issuing investment recommendations to portfolio managers should integrate ESG (including ESG company ratings) into their fundamental company analysis.




MSCI strongly believes that a systemic and large-scale integration of ESG considerations throughout the entire investment process will enable a more efficient allocation of capital globally towards the most productive assets in the long term and will contribute to a more effective and balanced transition towards a sustainable and inclusive economy.
