GMS Institute

The research engine behind the signal.

The Institute develops and peer-reviews the methodology that underwrites every SRS score and every Catalyst claim. Its outputs are public by default - because credibility compounds when the maths is in the open.

What we do

Three workstreams. One standard of rigor.

Methodology

Design, documentation and version control of the SRS framework - how questions are asked, weighted and benchmarked across 64 markets.

Public data

Selected benchmark datasets released under open terms so researchers, regulators and journalists can interrogate the numbers directly.

Applied research

Original papers on the link between perception and commercial outcomes - switching, retention, share price, talent acquisition.

Methodology, in brief

One framework. Any brand. Every market.

SRS is built from four dimensions of sustainability perception, measured consistently across markets and time. Weighting is transparent, peer-reviewed, and versioned. Score updates follow a documented release cycle.
