European Union – Environment. Article 2(1) of Directive (EC) 003/87, as amended, had to be interpreted as meaning that an installation for the production of polymers, in particular the polymer polycarbonate, which obtained the heat needed for that production from a third-party installation, did not fall within the scope of the greenhouse gas emission allowance trading scheme established by that directive, since it did not generate direct CO2 emissions. The Court of Justice of the European Union so held in a preliminary ruling in proceedings concerning the refusal to allocate greenhouse gas emission allowances free of charge to an installation for the production of polycarbonate.
