As environmental, health, and safety regulations have escalated, so too have the risks of owning and operating businesses subject to regulatory scrutiny and litigation. Our Environmental team helps clients in high-exposure sectors understand and appropriately mitigate these risks. We provide exposure analysis, develop tailored compliance strategies, and work with both corporate and financial investors to assess the environmental risks associated with business opportunities including negotiation of deal terms calibrated to clients’ risk tolerance.

Our team encompasses lawyers whose corporate, transactional, regulatory, and litigation experience gives them fluency across any environmentally-sensitive sector, including aviation, automotive, traditional and renewable energy, industrials, retail, semiconductors, electronics, infrastructure, chemicals, and real estate. We offer clients practical advice on issues spanning water quality and supply, air quality, permitting issues, regulation and remediation of hazardous substances (including PFAS and Proposition 65 matters), natural resource damages, reporting obligations, ESG matters, transactional due diligence and documentation, as well as advocacy before federal and state environmental agencies.
