Environmental Litigators: A Bench Trained in Small Firms

Environmental litigation lawyer hiring starts somewhere most large-firm search lists never look. Sartori & Partners data show that over three years, 20.1% of environmental litigators who changed firms, among those whose previous firm size is known, had left a firm under 150 lawyers. Across the Environment & Sustainability practice that share was 12.0%, and across all practices 11.4%. On arrival the picture is separate and just as distinct: firms of 1,000+ lawyers took 33.9% of environmental litigation moves in the 12 months to October 2026, against 53.6% of all lateral moves. Small firms train more of this bench than they do in most fields, and the largest platforms hire a smaller share of it.

Look first at where the movers sat before they moved. In the Sartori & Partners lateral database, firms under 150 lawyers were the previous firm for 20.1% of environmental litigators over three years, 8.1 points above the environment practice and 1.8 times the market's share. Firms of 150-399 lawyers add 16.9%, against 14.1% in the practice and 11.7% in the market. At the other end, firms of 1,000+ lawyers were the previous firm for 42.3% of environmental litigators, well short of the 51.3% seen in the practice and the 56.6% seen market-wide.

Environmental disputes are long, document-heavy and often local: site contamination, permits, toxic tort claims, cost recovery among owners and operators. Regional and boutique firms carry a large part of that work, so trial experience builds there. For a firm planning a hire, the practical step is to widen the source list well below its own size class. A search confined to large-firm peers covers a smaller part of this pool than it would in most other litigation fields.

The joining side tells its own story, read against the market's joiners rather than against the origin figures. Firms of 1,000+ lawyers took 33.9% of environmental litigation moves over 12 months, 19.7 points below their 53.6% share of all moves and under the 44.0% they took in the environment practice. Firms of 400-999 lawyers took 35.6%, against 23.4% market-wide, and firms of 150-399 lawyers 22.0%, against 13.3%. Firms under 150 lawyers took 8.5%, close to the market's 9.7%.

Mid-size firms are the main buyers in this speciality. A firm of 400-999 lawyers competing for an environmental litigator meets peers of its own size more often than the giants, which makes the offer about the docket, the bench of colleagues and the rate card rather than the brand. A firm of 1,000+ lawyers that wants this skill set is hiring against the grain of its own size class and should expect to make the case for why the practice belongs on its platform.

The level mix sets the speciality apart as well. Counsel made up 24.6% of environmental litigation moves in 12 months, 1.9 times the market's 12.7% and above the 19.5% seen in the environment practice. Partners were 37.3% of moves, against 27.7% across the market. Over three years the counsel share was 20.7%, against 12.1%, so the tilt is not a one-year effect.

A step in title came with 15.3% of these moves, against 12.9% market-wide. For the hiring firm this means a deep layer of senior lawyers below partner who can run a case day to day. It also means a counsel title is a common way in, and a clear path from counsel to partner is part of what wins the candidate.

No 12-month city list is published for this speciality, so the city view rests on three years. Over that period New York took 9.0% of environmental litigation arrivals, against 14.2% of all arrivals. Washington, DC took 7.8%, San Francisco 6.8% and Los Angeles 5.8%. Both California cities and the capital sit above their market shares, in line with the weight of federal agencies in the capital and of state environmental enforcement in California.

Only 18.4% of environmental litigation moves in 12 months involved a change of city, against 20.5% for all moves. Candidates are mostly found where the role is, so a firm opening an environmental seat in San Francisco or Los Angeles should search that city's smaller firms before trying to relocate someone.

Environmental litigation hiring held flat (-2.4%) year on year, at 123 moves in the latest settled 12-month window against 126 in the one before. The environment practice held flat (+7.1%), while lateral hiring across the market rose 9.0%. Partner hiring in the speciality held flat (-14.0%), at 43 against 50.

No 12-month list of hirers is published, so the firm view also rests on three years. Over that period 200 firms hired at least one environmental litigator, and the ten most active took 20.0% of individual hires, against 12.2% for the market's top 10. The list below shows those ten firms by rank and band.

With volume steady and buyers spread wide, no single firm sets the price. A well-placed environmental litigator will usually hear from more than one firm, and the firm that knows the candidate's current shop and docket will move fastest.

Source from below. Firms under 150 lawyers were the previous firm for 20.1% of environmental litigators who moved over three years, against 11.4% across all practices; add firms of 150-399 lawyers and the pool outside the large platforms is wide. Expect mid-size competition: firms of 400-999 lawyers took 35.6% of 12-month hires, against 23.4% in the market. Build the offer around the counsel level, which carried 24.6% of moves, and plan for a market where the count of moves stays level rather than growing.

A lawyer coming from a small firm will ask about leverage, conflicts and rate structure early. Have the answers ready before the first meeting: they decide more of these moves than title.
