CBAM and the Global South, The Unintended Consequences of the EU’s Carbon Pricing System


The EU has embarked on an aggressive path of decarbonization. The ETS (Emissions Trading System) is a “cap and trade” scheme: “cap” refers to an overall limit to carbon dioxide that the EU permits; “trade” refers to permits that can be bought and sold by firms whose production activity will cause carbon dioxide emissions.

Carbon embodied in imports constitutes about 20 percent of the EU’s total emissions. To reduce the imported emissions, it has put forward a proposal called the Carbon Border Adjustment Mechanism (CBAM). Other countries e.g. the US, Canada, and Japan are planning similar measures.

The CBAM involves imposing tariffs on imports from countries that do not “price” carbon appropriately, and hence, use carbon-intensive methods of production. All imports to the EU will be subject to this test.

Global South countries will struggle to deal with unintended consequences of the EU carbon pricing scheme: they are being asked to limit additions to the stock of carbon from now on. This is without any significant financial transfers, or, more importantly, in this case, a transfer of technology.
