This panel will explore the ethical challenges and responsibilities of attorneys advising clients on environmental challenges, climate-related issues, and issues relevant to Corporate Social Responsibility (CSR). The panel will address the ethical responsibilities of attorneys representing carbon contributors, including situations in which the client’s objectives may be contrary to the attorney's personal views and values. Panelists will apply the rules of professional responsibility to scenarios of urgency and will also discuss the fulfillment of an attorney’s personal ethical responsibilities relating to GHG emissions, the attorney’s duty to pursue the client's legitimate interests within the bounds of the law, and particular challenges of representing corporations. The presentation will focus ethics rules, including Model Rules 1.6, 1.13, 1.16, 2.1, 3.3, and 4.1.
