Working With CCSI

Senior Legal Researcher, Climate Law and Finance

Columbia Law School’s Columbia Center on Sustainable Investment (CCSI) and the Sabin Center for Climate Change Law are recruiting a Researcher to support a new initiative on climate law and finance. The researcher will work collaboratively with CCSI's and the Sabin Center’s Leadership and Research Staff to analyze the interrelated legal, finance, and policy pathways critical to achieving global climate goals and facilitating the energy transition, and the corresponding implications for public, private, and institutional financial sector actors, regulators, and alliances. Successful candidates will have a good understanding of how financing and investment can play a role in addressing climate change and the critical importance of appropriate systems, laws, policies and practices to achieve climate goals and facilitate the energy transition. Successful candidates will also demonstrate willingness to learn new areas and to work in a highly interdisciplinary, flexible, and dynamic environment.

Internship opportunities available for Spring 2023 (remote possible):

Paid internship: Legal and Policy Research on Energy, Climate Change, and Sustainable Development (Native or Fluent Spanish Speaker)

CCSI is seeking an LLM or JD student intern with native or fluent Spanish skills to assist with legal and policy research, writing, and other activities relating to various projects in CCSI’s energy and climate change work. Tasks will include cataloging and examining the allocation of liability for decommissioning of offshore oil and gas facilities and infrastructure in leases and contracts for extraction of fossil fuels in various jurisdictions; identifying, cataloging, and examining best practices in the relevant scholarly and practitioner literature regarding the prevention of environmental pollution and liability-shifting away from the lessee; and identifying potential statutory, regulatory, and contractual improvements to existing regimes or practice. Preference will be given to candidates with strong legal research and writing skills, and candidates who have experience or demonstrated interest in issues relating to energy or climate change.

Paid internship: Open Land Contracts 

CCSI is seeking a highly motivated, organized, and detail-oriented undergraduate or graduate student intern to help with the administration of CCSI’s transparency tool: OpenLandContracts.org. The intern will assist with the management of certain administrative tasks associated with the website, which aims to empower communities, civil society organizations, host governments, and other actors to better understand the details of deals surrounding agriculture, forestry, renewable energy, and other land-based investment projects in the global south. Strong preference will be given to candidates native or fluent in French. Knowledge of Python script could also be helpful but is not essential. Work study allocations are an asset but not required. Time commitment: Adhoc, as needs arise.

Paid internship: Antitrust, ESG, and Sustainability Mapping 

Over the past few years, there have been growing academic, political, and social debates about the boundaries of competition and collaboration in markets for non-economic benefits, including efforts to mitigate environmental impacts, to accelerate the energy transition, to protect human rights, and to advance worker rights and prosperity. Questions and controversies have arisen both with respect to joint standard-setting and activities among companies and industry-wide collaborations, as well as with respect to coordinated engagement by investors and financial institutions. Increasingly, antitrust-related questions and challenges are said to be chilling necessary engagement and mobilization of private actors to address climate and other sustainability-related challenges. CCSI and the Sabin Center are undertaking a multidimensional mapping of this problem space, identifying the parallel and intertwined debates and legal questions, the political and other challenges and dynamics, and the range of actors at the center of the debate. Preference will be given to law students with a background in competition law.

Paid internship: Integrating Climate and Human Capital Management Considerations in Asset Allocation and Strategy

CCSI and the Earth Institute’s Research Program on Sustainability Policy and Management are seeking graduate student interns to assist with reviews of academic and practitioner literature concerning, respectively, climate change and human capital management as relevant to investment strategy. This work will support a broader project focused on helping a large public pension fund understand the potential impact of environmental, social, and governance factors on the long-term value creation and effective risk management within its investment portfolio, and to draw larger lessons applicable for universal asset owners, especially ones that are intergenerational and fiduciaries to their members. Students with relevant experience in law and finance are strongly encouraged.

Unpaid internship: SDG-Aligned Finance and Investing

CCSI seeks to strengthen the alignment of global finance and investment with the Sustainable Development Goals. On one hand, there remains a substantial financing gap for the investments needed to achieve the Sustainable Development Goals, including the global energy transformation. On the other hand, despite the widespread recognition of the risks to, and opportunities for, investors and other financial actors with respect to the SDGs, existing practices, standards, disclosure frameworks, and metrics are not sufficient to meaningfully shift practices or to address the major financing needs. CCSI seeks one or more students to conduct research and analysis to support its work in this area. Preference will be given to students with experience or familiarity with ESG and other investing frameworks and reporting standards, banking and investment products (e.g. debt, equity, bonds), objectives and trends in responsible business practices, investment promotion and screening, among other areas.

Unpaid internship: International Investment Law and Policy

CCSI is seeking JD and LLM students to support a number of projects requiring research and analysis of international trade and investment treaties, treaty-based investor-state arbitration claims, and debates around reform of the investment treaty regime. The intern may also be asked to help with the coordination of our annual Executive Training on Investment Treaties and Arbitration for Government Officials. Familiarity with international investment law is required. Preference will be given to applicants with strong research and writing skills.
