How the EU ETS reshaped trade and what it means for CBAM

A new study from de Santis and colleagues looks at how the phased rollout of the EU Emissions Trading Scheme changed trade flows inside Europe. The main finding: intra-EU imports rose in sectors covered by the ETS, even though carbon pricing made those goods more expensive to produce. That suggests better regulatory alignment and lower trade friction outweighed the cost advantage of importing from outside the EU. The same study found no clear cost penalty for European exporters. Exports did not drop after the ETS was introduced. The authors reached this conclusion by comparing ETS-affected sectors with unaffected sectors, which helps rule out a general trend toward deeper EU integration. This matters for the EU's Carbon Border Adjustment Mechanism, which starts rolling out in 2026. If the ETS experience holds, CBAM may not simply redirect imports to lower-cost non-EU suppliers. Compliance alignment could keep more trade within the EU than simple cost models predict.

Interesting result. The finding that intra-EU imports rose despite carbon pricing suggests regulatory alignment matters more than pure cost for a lot of supply chains. Would be curious if the effect holds for smaller suppliers or only large integrated firms.

That is a good question. The summary does not break out firm size, so the full working paper would be needed to see whether small suppliers benefit the same way. The regulatory alignment effect might not scale down evenly.

The export result is the one to watch. If ETS didn't hurt exporters, then CBAM's trade effects might be smaller than the headline fears. But the paper covers the EU ETS, not border adjustments, so I'd be careful applying it directly.

Good to see actual data on trade flows instead of just theory. The comparison between ETS and non-ETS sectors is the right way to isolate the effect. Still, the paper is from 2026, so it covers a very different energy price environment than now.

Does the study distinguish between goods that are hard to shift and goods where supply chains can relocate? Import behavior during ETS phases tells us about the past, not necessarily how CBAM will hit sectors with easier substitution.
