Environment & Climate Change


We handle some of the world's largest and most sophisticated matters requiring the resolution of complex environmental issues. We are well-equipped to assemble international teams of experienced environmental lawyers on matters anywhere in the world, whether handling cross-border transactions with assets in several jurisdictions or advising global clients on local environmental regulations relevant to their operations.

Clients value our understanding of the ever-changing environmental regulatory landscape, making our Firm a market leader in environmental law. We offer well-grounded legal advice and counsel in connection with compliance issues, transactions, and disputes concerning environmental requirements and potential environmental damages. Our practice advises on a gamut of environmental laws from local remediation programs to national environmental policy regulations to international climate change treaties.

  • Environmental litigation and enforcement
  • Environmental due diligence and transactional advice
  • Environmental compliance and regulatory advice
  • International environmental law
  • Climate change
  • Remediation and development of contaminated properties
  • Environmental impact assessment and approval of energy, infrastructure, resource and development projects

Our team handles some of the world’s most sophisticated transactions that require the resolution of exceptionally complex environmental issues. We are the 'go-to' firm for clients engaging in environmentally-sensitive M&A transactions. We have the ability to provide advice on a wide range of environmentally-complex transactions from modest investments and leases to large, multi-national, and multi-billion dollar acquisitions and divestitures. In transactions, we identify and assess potential environmental liabilities and manage responsibility for known and potential environmental risks. Our team is one of the most experienced environmental teams in advising buyers, sellers, lenders, underwriters, and developers in mergers, acquisitions, divestitures, financings, project development, securities offerings, bankruptcies, real estate transactions, and governmental cleanup programs. Our practice coordinates environmental site assessments, audits, and permit transfers; structures transactions to minimize environmental risk, including via the procurement of insurance; and drafts and negotiates the critical environmental provisions of transaction documents. After deals close, we work with clients to pursue the post-closing resolution of issues identified in the course of due diligence.

While we advise on multi-billion dollar deals, we also represent an exceptionally large range of corporations, investors, developers, lenders, and sovereign governments in transactions of all sizes involving environmentally-complex matters that require careful environmental analysis and advocacy. While we work on deals with dollar values in the billions, we take special pride in our success in also handling matters that are smaller in terms of dollar value, but which often involve the most complex environmental issues and the most difficult negotiations.

Our team handles cutting-edge international environmental law issues, including climate change work. We offer clients a market-leading climate change practice. We advised a sovereign nation in connection with the global climate change treaty negotiations to develop a successor to the Kyoto Protocol, which resulted in the Paris Agreement to the United Nations Framework Convention on Climate Change. We are advising on an environmental treaty related to an international marine ecosystem. We have experience in interpreting and helping clients comply with the environmental and social standards of multilateral development banks, such as the World Bank and International Finance Corporation, as well as evolving international standards, including the Equator Principles.

Our environmental litigation practice also remains vibrant as we are engaged in cutting-edge disputes involving contaminants, for which evidence of adverse health effects is emerging and enforceable standards are changing rapidly. In litigation, we represent clients relating to remediation of contaminated sites, compliance with environmental laws, environmental insurance coverage, rights and obligations under environmental contractual indemnities, and environmental liabilities in bankruptcy.

The global nature of our environmental practice and the constant communication among its members allows us to exchange experiences from our different jurisdictions with regard to international or cross-border environmental liability, and other matters with an international or comparative law relevance, giving us a distinct advantage over local environmental firms.
