Notable Representations, Key Contacts

Environmental matters often present some of the most difficult, technical and potentially significant issues that arise in corporate transactions. Strict liability regimes, combined with complex and ever-changing regulatory requirements and increasing public awareness of environmental and sustainability concerns, can create tangible business risks and opportunities for companies and their investors. Our highly skilled and experienced lawyers have a thorough understanding of how environmental matters can and do affect businesses – from a financial and reputational perspective – and an impressive track record of developing creative solutions to address environmental risks and capture environmental opportunities in a transactional context.

Weil attorneys are experienced at identifying, quantifying and contractually allocating environmental liabilities that may arise in the context of domestic and cross-border transactions, including equity investments, mergers and acquisitions, joint ventures, corporate restructurings, infrastructure projects and financing transactions. We represent buyers, sellers, lenders, investment banks and investors, including private equity firms and financial institutions as well as other businesses in all phases of corporate and real estate transactions. Weil offers a full range of transactional services, including conducting and coordinating due diligence investigations of potential environmental liabilities; quantifying those liabilities in the context of the clients’ overall business strategy; advising on and negotiating contract provisions, disclosures and environmental insurance policies; and transitioning environmental functions at target entities into acquiror business structures. We also are adept at facilitating financing in debt and equity markets, and frequently assist clients in preparing environmental disclosures required under various securities laws and capital market requirements. In addition, Weil attorneys are skilled at identifying emerging business opportunities and risks associated with changing environmental policy, including those relating to unconventional oil and gas production, renewable energy development and greenhouse gas regulation.
