As I understand it, the EU’s position on the compromise will:

Seek reduced catch limits in the Northern Hemisphere, that would guarantee a significant improvement in the conservation status of whales in the long term, moving towards the final goal to ban the whaling activities which are not in line with the moratorium on commercial whaling within an agreed time-frame.

And:

Support phasing down significantly all whaling in the Southern Ocean over the coming years and having a phasing out of whaling in that Ocean within an agreed time-frame.

My reading is that they will buy into the compromise.
