A recent Electrek article argues that while Trump's proposal to tariff Canada over wildfire smoke is misguided, the underlying concept of making polluters pay across borders could support a global carbon border adjustment mechanism (CBAM). The piece notes that carbon pricing is widely supported by economists as a way to correct market distortions from unpriced emissions. The article points to existing examples like the EU's CBAM and the California-Quebec cap-and-trade linkage as proof that international carbon pricing cooperation is feasible. It suggests that even without participation from major emitters like the US and China, other countries could collectively impose tariffs proportional to climate damage caused by exports.
