How it works

Three steps from raw data to a portfolio you can act on.

Meridian pulls live quarterly financials, ESG risk ratings, and legally-mandated emissions disclosures for every company in the S&P 500.

Then it turns those numbers into three things: a sustainability score, a net-zero stress test, and a portfolio built from both.

Sustainability Score

Every company, ranked against an ideal

Rank every company against an objective, mathematically weighted ideal — not by opinion.

Net-Zero Scenario

Model who survives the transition

Model exactly where the shock lands when the world commits to net zero, and who survives it.

Portfolio

A long/short book, ready to trade

Turn every score into a risk-adjusted, long/short portfolio your portfolio manager can act on.
