With the Biden-Harris administration in office since January 2021, the Sabin Center’s work has shifted once again,from a focus on COVID-19 and theTrump administration’s deregulatory agenda to the renewed federal government commitment to climate action and ongoing climate developments at the state and local level, in the private sector, and in the courts.The Sabin Center is now keeping track of the Biden-Harris administration’s efforts to undo Trump’s attacks on environmental law and science through a recently launched Climate Reregulation Tracker, alongside our numerous online resources and our Climate Law Blog. More generally, the Sabin Center continues to conduct independent research to produce publications and useful resources; advances new techniques and direct engagement; and partners with agencies, NGOs, and the private sector to promote climate action.
