Growth process NS sees the impact calculation as a growth process. In 2016, we did not broaden the transport chain scope or the quantifiable themes. Over the next few years, we will focus on further integration of the social impact calculation into investment decisions.We are publishing the methodology, the underlying principles and the choices made on www.ns.nl/mvoberekeningen (Dutch only) so that the results can be put in the appropriate context. NS is doing this to inspire other companies and help develop a standard for calculating social impact. In 2016, NS provided a study case on calculating social value as part of the curriculum at Yale. NS is also helping to create a standard for impact analysis, for instance by taking part in 2016 in the ‘Social Value Creation’ initiative by De Groene Zaak, a Dutch partner of the World Business Council for Sustainable Development.
