We find
the way
We help companies act responsibly, safely, and in line with regulations, no matter the scale of the challenges. We know how investments look from the inside and how the law can complicate them. That is why at ERS we turn regulations into clear solutions.
We are a law firm that speaks the language of business, not legal codes. We know everything about investment challenges. This is our only practice. We do not do it alongside other practices or specializations. We help industrial and manufacturing companies, as well as investors, run their business safely and in line with regulations, even in the most difficult situations. Both as an external law firm and as an in-house team for hire.

No long reports full of theory.
We prefer to design clear strategies.
We speak directly, so our clients always know where they stand. We consider not only the law and practice, but also your business, timelines, financing, and client relations.
Energy, chemical industry, automotive, life sciences, developers of large projects – we work with sectors that have a direct impact on the environment. We also support international law firms as their local partner in Poland.
How we work?
ERS Legal is a specialized law firm. We advise on complex regulatory matters in environmental law, investment process safety, and product law.
We build our firm on over 25 years of experience. This experience comes from leading international law firms. We worked on strategic projects in industry, energy, infrastructure, and manufacturing. In practice, this means we know difficult cases. We understand what can go wrong. We manage risks before they become problems.
We combine high standards of international law firms with direct access to specialized lawyers. We act like an external legal team. We stay close to the business and the problem. We are fully involved in every project.
We advise Polish and international clients. We also act as the first choice environmental counsel for international law firms. This includes firms in Poland and those supporting clients investing in Poland.
We understand what global law firms expect from a local advisor: speed, precision, and responsibility for the result.
Our practice is based on three areas:
- environmental law
- investment process safety
- product law and product compliance
We do not focus on describing regulations. Our role is to solve problems and turn complex rules into clear business decisions.
