The EU proposal for aCarbon Border Adjustment Mechanism: an advanced tool to combat 'carbon leakage', anew EU own resource of 'moral suasion' for third Countries?

With the proposal for a Regulation of the Europe-an Parliament and of the Council establishing a Carbon Bor-der Adjustment Mechanism (CBAM) adopted on July 14, 2021 by the European Commission, it begins to reach the heart of the global debate on the opportunity to adopt mechanisms to combat the phenomenon of 'carbon leakage', that is the attempt to evade existing carbon pricing systems through the delocali-zation of the most polluting activities. In this way, the European Union demonstrates its serious intention to strengthen actions against climate change and to identify customs taxation as an in-strument to guide the choices of its trading partners and, there-fore, of the major world economies. The precautions adopted in the application of the CBAM and the long transitional period before its entry into force, however, prevent the full appreci-ation of its potential repercussions (also) in terms of the new own resource of the European budget.
