Clients seek our help in navigating a range of evolving needs, including:

  • Navigating voluntary sustainability reporting, including in the selection of frameworks and disclosures relating to climate and other sustainability goals
  • For private funds, calibrating sustainability and climate-related commitments and approaches, advising sponsors on the formation of sustainability-focused and impact funds, and balancing evolving investor expectations and reporting requirements
  • Conducting comprehensive, customized and targeted due diligence, including in the context of M&A and financing activities
  • Developing and strengthening internal and external policies, procedures and governance structures

  • Responding to litigation and enforcement risk within the context of company-sponsored activity, business relationships and disclosures (including green/social washing claims and transnational litigation and disputes)

…and more—often novel—considerations.
