Environmental Deregulation: 100+ Rules Rolled Back Across Four Years

The administration's approach was systematic: identify Obama-era environmental regulations, determine legal and administrative mechanisms for reversal, and implement reversals. The rollbacks covered air quality, water quality, climate, wildlife, and chemical safety. The vehicle emissions standards rollback was estimated to add approximately one billion tons of additional carbon dioxide to the atmosphere by 2035. Courts overturned many of the rollbacks, finding procedural defects. The Biden administration reversed the majority of the remaining reversals. The cumulative effect on environmental law precedent and the transition costs of the repeated changes were lasting.
