Well I searched on the United Nations website and it said The roadmap suggests that, by 2050, the EU should cut its emissions to 80% below 1990 levels through domestic reductions alone (i.e. rather than relying on international credits).
This is in line with EU leaders' commitment to reducing emissions by 80-95% by 2050 in the context of similar reductions to be taken by developed countries as a group.
To reach this goal, the EU must make continued progress towards a low-carbon society. Clean technologies play an important role.
Don’t know if this helps but I hope it does
