To secure the deal voted on today ….and avoid a trade war over environmental regulations …the EU agreed to include provisions that “soften” the impact of its carbon border tax on US exporters:

• Reporting Exemptions: The EU granted the US an expanded “de minimis” exception. This means that roughly 90% of US firms exporting carbon-intensive goods (like steel or aluminum) are now exempt from the most rigorous CBAM reporting and certificate obligations, provided their shipment volumes fall below a certain threshold.

Administrative Relief: The agreement commits the EU to ensuring that its Corporate Sustainability Reporting Directive (CSRD) does not create “undue restrictions” on US trade. Essentially, the EU is making it easier for US companies to “prove” their environmental standards without matching the EU’s exact internal bureaucracy.  

• The “Equivalency” Dialogue: Both sides agreed to a formal process to determine if US state-level climate policies (like those in California) or federal subsidies for green tech can be considered “equivalent” to the EU’s carbon price. If deemed equivalent, US goods would face significantly lower (or zero) carbon levies at the border.

Why this matters: The Ghost of GASSA

Before the Turnberry Agreement, the US and EU had spent years trying to negotiate a Global Arrangement on Sustainable Steel and Aluminum (GASSA), which was intended to be a true “green club” where members traded low-carbon metals freely while taxing “dirty” imports from countries like China.

Those talks effectively collapsed in 2025. The Turnberry deal is seen as the “pragmatic replacement”:

• Instead of a complex carbon-intensity formula, they settled on a 15% tariff ceiling.  

• The EU gets the US to stop threatening retaliatory tariffs, and in exchange, the EU “pauses” the full weight of its carbon tax on American industry.
