“The Sabin Center’s new online tool – the Climate Backtracker – will identify steps taken by the Trump-Vance administration to scale back or wholly eliminate federal climate mitigation and adaptation measures. The Backtracker is the third iteration of Sabin Center climate regulation trackers. The first was the Climate Deregulation Tracker which tracked climate-related regulatory actions under the first Trump administration (2017–2020), followed by the Climate Reregulation Tracker which tracked actions under the Biden Administration (2021–2024). The Climate Backtracker will begin capturing actions on the first day of President Trump’s term today — January 20, 2025.  “During the four years of Trump 1.0, the administration worked to repeal many of the climate regulations adopted under Obama, but it took them a lot of time and they often messed up procedurally, leading to many reversals in court. Trump 2.0 is much better prepared and will probably issue many more decisions quickly. This can be dizzying for companies that need to comply, for advocates who oppose (or support) these actions, and for all those who care about the climate. Our Climate Backtracker will keep tabs on these Trump administration actions so that everyone will be able to see what is happening and react as they see fit,” said Sabin Center Faculty Director Michael Gerrard.
