  • The Advanced Consortium on Conflict, Cooperation and Complexity strives to foster sustainable peace by enabling and supporting integrative research and constructive conflict engagement.
  • The Center for Climate Systems Research works closely with the NASA Goddard Institute for Space Studies to advance climate science and improve societal resilience to challenges in the United States and around the world.
  • The Center on Global Energy Policy advances smart, actionable and evidence-based energy and climate solutions through research, education and dialogue. Its scholars cover every source of energy throughout the world.
  • The Center for International Earth Science Information Network works at the intersection of the social, natural, and information sciences, mapping human interactions with the environment on fine scales across the world.
  • The Center for Resilient Cities and Landscapes uses planning and design to help communities and ecosystems adapt to the pressures of urbanization, inequality and climate uncertainty. It works with public, nonprofit and academic partners.
  • The Center for Sustainable Urban Development addresses urban sustainability, equity and planning issues, including land use, infrastructure, transport and education.
  • Climate Science, Awareness and Solutions works to halt the global march toward catastrophic climate change by connecting the dots between basic science, public awareness and policy actions.
  • The Columbia Center on Sustainable Investment works with governments and industries to attract, encourage, and shape investment that advances the well-being of the planet and all its citizens.
  • The Columbia Electrochemical Energy Center works to overcome the intermittency of solar and wind power by addressing energy storage and conversion using batteries, fuel cells, and electrolyzers in transformative ways.
  • The Columbia Water Center tackles challenges where water and climate interact with food, energy, ecosystems and urbanization. Combining scientific research with policy, it aims to design reliable, sustainable models of water management.
  • The International Research Institute for Climate and Society aims to enhance society’s capability to anticipate and manage the impacts of medium-term climate trends, especially in developing countries.
  • Lamont-Doherty Earth Observatory develops fundamental knowledge about the origin, evolution and future of the natural world, from the planet’s deepest interior to the outer reaches of its atmosphere.
  • The Lenfest Center for Sustainable Energy develops new technologies to provide energy while maintaining the stability of the earth’s natural systems. It works across natural sciences, engineering, social sciences and economics.
  • The NASA Goddard Institute for Space Studies is affiliated with Columbia University. It broadly studies natural and human-driven changes in our environment, especially atmospheric forces leading to global warming.
  • The National Center for Disaster Preparedness works to understand and improve the nation’s capacity to prepare for, respond to and recover from disasters, through both governmental and non-governmental systems.
  • The Resilient Coastal Communities Project seeks to foster actionable, equitable solutions to flood risks along with complementary benefits like habitat restoration, job creation and more empowered communities.
  • The Sabin Center for Climate Change Law develops legal techniques to fight climate change, trains students and lawyers in their use, and provides up-to-date resources on key topics in climate change law and regulation.
  • The Quadracci Sustainable Engineering Lab addresses practical engineering issues to help bring sustainable energy, water, health and other resources to people, especially in the developing world.
