How useful or accurate these scores are in pursuing sustainable investment opportunities that make a difference is an evolving process that has been the subject of much debate. We have put this to the test by including our SDG Framework in our SI Open Access Initiative. In this way, we share the SDG scores of over 12,000 companies with clients and academics, offering them the ability to comment on these scores and use them in their investment strategies and research, while also giving us valuable feedback.

Still, all these different ratings systems which can be overlapping and sometimes even contradictory can be confusing. A new academic paper written by Robeco’s SI specialists and external academics digs deeper into these issues and aims to slice through this confusion and advance the debate on sustainable investing ratings in two ways.

First, the paper delineates principles that can inform the development of sustainable investing ratings that aim to support sustainable development. Second, it introduces the Robeco SDG score as a novel metric of sustainability performance that corresponds to these principles. This SDG score is made available for free via SI Open Access in order to enable research, spark discussion, and further the state of sustainable investing ratings.
