The White House published a Council of Economic Advisers memo describing President Trump’s deregulatory programme and estimating that halting proposed Biden-era regulations has avoided more than USD 180 billion in costs, equivalent to USD 2,100 per family of four. The memo estimates the Biden Administration added more than USD 1.8 trillion in new regulatory costs, with 72% attributed to Environmental Protection Agency rules, and argues that rolling back automobile-related rules would save consumers more than USD 1.134 trillion. It also highlights executive-order actions including a ten-out-for-one-in approach to new rules through a “1-in-10-out regulatory budget,” a pause on new regulations (with USD 180 billion cited as the projected cost of the halted rules), elimination of DEI across agencies, and measures to boost domestic energy production. Examples of cited high-cost Biden rules span multiple agencies, including USD 84.1 billion for beneficial ownership reporting to the Financial Crimes Enforcement Network, USD 45.2 billion for Department of Transportation fuel-efficiency mandates, and Department of Health and Human Services and Department of Defense rules each cited at tens of billions of dollars in costs.
