Hedegaard: I would be very, very happy if Europe very soon agrees that this [40% carbon cut], what we are proposing today, is the level.

Barroso: We are having first European council meeting in March [on this subject]. Reality is that some member states would prefer not to go so far. They would prefer to be below 40%. And there is a discussionin society. No capital was suggesting more than 40%. Even the more committed leaders in terms of climate action. No one was suggesting more than 40%. One important point that we should have in mind is that this is a package.

I remember in 2007, we proposed this in European council, first reaction was very negative, because some countries thought 20% was too ambitious. Afterwards, they saw they could get some important points through the package: for example, secruity of supply.

It's not easy for 28 countries, with different energy mixes, with different attitudes of the public, to get agreement... Yes, I think it is possible to come to agreement on 40%, I think we can do it.
