Navigating shifting environmental winds worldwide

Changes in environmental law, policy, and public opinion dramatically impact business success and brand credibility. From proactively shaping policy to rapidly responding to litigation or enforcement threats, we leverage an unrivaled global platform to help you advance business objectives in the face of a dynamic regulatory, political, and legal landscape.

Key stakeholders are focused on environmental risks and opportunities like never before. That’s why we serve as strategic partners looking beyond day-to-day issues to anticipate and navigate evolving trends, politics, and agendas – always with your long-term goals in mind. From business-critical operations and compliance to defending novel or aggressive litigation and enforcement actions, we find pathways to advance commercial objectives while balancing and mitigating risk.

The federal, state and local environmental rules that impact your business span chemical substances, air, water, solid and hazardous waste, pesticides, community right-to-know, and myriad other areas. We can help you identify where regulations intersect with your operations and craft proactive, sustainable strategies to mitigate litigation and enforcement risk. And to keep you ahead of the curve on emerging issues, we have developed unique, multi-disciplinary Task Forces to track, anticipate, and advise on cutting-edge issues related to PFAS and emerging contaminants, plastics, environmental justice, ESG, and State AG Enforcement trends.
