ERS Legal is a boutique environmental law firm based in Warsaw, Poland. We focus on three areas: environmental law compliance and litigation, investment process security, and product and EU regulatory law.

The firm was founded in 2026 by partners who built and led the environmental and regulatory practices at a leading global law firm. We bring big-law depth to a focused, partner-led model, backed by a Band 1 Chambers Europe ranking in Environment (Poland) and more than 27 years of practice.

We advise Polish and international companies across manufacturing, energy, real estate and industrials, alongside public bodies, on:

- securing industrial, energy and infrastructure investments, including NGO and NIMBY defence and stakeholder management; 

- EU product and chemicals regulation, including REACH, CLP, PFAS, PPWR, BPA, food contact materials and product stewardship.

We speak the language of business, not paragraphs.
