SI Intro

We believe that investors and other financial market participants must act to prevent the worst effects of a warming climate and to integrate financially relevant environmental, social and governance (ESG) considerations into their investment processes.

By driving the transition to an economy that removes as much greenhouse gas as it puts in, and by embedding ESG as a core component of portfolio construction, investors can manage emerging risks, identify new opportunities and align their portfolios with a changing world.


Our call to action

MSCI urges investors globally to integrate climate ESG and climate considerations throughout their investment processes if they are to contribute to an effective and balanced transition toward a new era of sustainable growth.
