Recital 11

A range of fraudulent practices have occurred in spot secondary markets in emission allowances (EUA) which could undermine trust in the emissions trading scheme, set up by Directive 2003/87/EC of the European Parliament and of the Council, and measures are being taken to strengthen the system of EUA registries and conditions for opening an account to trade EUAs. In order to reinforce the integrity and safeguard the efficient functioning of those markets, including comprehensive supervision of trading activity, it is appropriate to complement measures taken under Directive 2003/87/EC by bringing emission allowances fully into the scope of this Directive and of Regulation (EU) No 600/2014 of the European Parliament and of the Council, by classifying them as financial instruments.
