Automakers get a compliance loophole buried in emissions bill

What it does

This bill modifies federal fuel economy (CAFE) and greenhouse gas emissions standards for vehicles. It allows the EPA and Department of Transportation to adjust emissions targets for 2035 based on market conditions and technology, creates a 'deemed compliance' mechanism where meeting one standard automatically satisfies the other, and requires the EPA to establish new heavy-duty truck emissions standards by 2027 based on technological feasibility and economic impact rather than aggressive climate targets.

Why we flagged it

Despite its 'Freedom' framing, the bill's core mechanism is to weaken existing EPA and NHTSA emissions standards by introducing discretionary adjustment authority, creating compliance loopholes, and prioritizing industry economic concerns over environmental outcomes. The 'deemed compliance' provisions are the functional centerpiece—they allow manufacturers to meet only the less stringent of two overlapping standards.

What the text implies

• The 'deemed compliance' mechanism (Sections 403–404) creates a regulatory arbitrage: manufacturers can choose to comply with CAFE standards alone and automatically satisfy greenhouse gas emissions standards, or vice versa. This allows them to meet whichever is weaker, effectively lowering the binding constraint.
• The bill's requirement that heavy-duty truck standards be based on 'affordability' and 'economic impact on motor vehicle manufacturing job quality' (Section 411) introduces cost-benefit language that may allow EPA to justify weaker standards than current law requires, shifting the regulatory burden away from industry.
