One of the leading figures in European climate policy, Peter Vis, just last month fretted that the European Union might be rushing too fast towards the sort of border carbon tax it voted for this week.
Such a tax might put “the EU in the role of judging the adequacy of other countries’ [climate policies], which is awkward”, Vis, who helped oversee the creation of the EU emissions trading system, told the UK climate journal, The ENDS Report.
