The campaigners asked the court during hearings in December to order Anglo-Dutch multinational Shell to reduce emissions by 45 percent by 2030 in order to help achieve that goal.
Around 45% of the European Union's output of greenhouse gases is regulated by the Emissions Trading System (ETS), the bloc's flagship policy to tackle global warming by charging for the right to emit carbon dioxide (CO2).
Emissions from power and heating generation fell by 17.1%, to 632.8 million tonnes, the analysts said on Thursday.
