ISS STOXX

ISS STOXX (product suite)

ISS STOXX, part of Deutsche Börse Group, offers an integrated Climate & Nature Analytics suite spanning more than a thousand indicators across emissions, transition and physical risk, net-zero alignment, scenario-based climate Value-at-Risk, biodiversity impact and water risk for investors, banks and insurers. Its geospatial, asset-level physical-risk modelling — extended by the 2025 acquisition of Sust Global — projects acute and chronic hazards under multiple IPCC, NGFS and IEA scenarios, delivered through the DataDesk platform and APIs. Distinctive as a broad index-and-data house carrying climate and nature into mainstream investment and risk workflows.

Public transparency, not model quality i

Product-level: public materials indicate risk scope and outputs, but little detail on modeling approach.

Product-level: the public Physical Risk Solution document is a short scenario fact-sheet — it names the scenarios and asserts per-hazard impact functions and a valuation model, but discloses no model logic, resolution or hazard-level detail and points to non-public methodology documents. No reconstructable public method.

For further information, see the section 'Transparency Score methodology' in the Readme.
