"I would expect the 1 December deadline should be achieveable without any trouble," UN official Andrew Howard said. The European Commission wants all 27 European Union member states to link simultaneously, but that deadline may be a problem for new EU member states Bulgaria and Romania, said European Commission climate official Artur Runge-Metzger.
"From our side there's certainly political commitment to make the connection happen. We are certainly aware that there may be a problem with Bulgaria and Romania."
"When it comes nearer to 1 December we'll have to decide how much damage will be done by leaving one or two member states out."
