How the Index works
01 The ranking

Leading Environmental firms by Index

These are the law firms with the strongest public Environmental footprint, ranked by the Sartori Firm Index — a 0–100 measure of scale, reach and hiring built entirely from public data. The ranking reflects how large and active each firm's presence is, not the quality or prestige of its environmental practice. Depth labels (“major”, “strong”, “present”) show how central environmental is to each firm relative to its size. Headcount is the attorney footprint we map from public sources, shown as ranges.

Environmental firm rankings — common questions

How are the top Environmental firms ranked?

Firms are ordered by the Sartori Firm Index — a 0–100 score built from public signals (scale, geographic and practice reach, live hiring). This page lists firms for whom environmental is a leading practice. The Index measures public footprint and momentum, not the quality of any firm's environmental work.

What does the depth label mean?

“Major”, “strong” and “present” describe how large a share of the firm's mapped attorneys work in environmental, relative to the firm's overall size — a footprint signal, not a quality judgement.
