BERLIN (Reuters) - The three-party talks aimed at forming Germany's next government could still fail unless the sides achieve more progress on climate protection measures, the co-leader of the German Greens said on Friday.
The stark warning comes as the haggling between would-be Chancellor Olaf Scholz's centre-left Social Democrats (SPD), the Greens and the business-friendly Free Democrats (FDP) entered the final straight.
Robert Habeck told public broadcaster RBB the government that succeeds Angela Merkel's outgoing conservative-led administration must be a "climate government", committed to the Paris Climate Agreement target of capping the global average temperature increase at 1.5 degrees by 2100.
"If we don't manage that - 1.5 degrees is our yardstick, it's in our provisional agreement ... then we have failed in the coalition talks," he said.
His comments came as the U.N. climate summit in Glasgow entered what was scheduled to be a final day of bargaining over how to stop global warming from becoming catastrophic.
Next week, the SPD, the Greens and the FDP will assess the agreements made in coalition talks on a whole range of policy areas and decide how to proceed with government-building.
A collapse in the talks would plunge Germany, and the European Union of which it is by far the richest and most populous member, into deep crisis.
The more fragmented parliament returned by voters in September's election makes for complicated coalition arithmetic.
Among the few alternatives would be a repeat of the grand coalition that has ruled Germany for the past eight years, though this time under SPD instead of conservative leadership. Few in either party want this.
In a sign of their disquiet over the results of climate policy talks, the Greens' leadership last week wrote to a range of activist groups asking them to pressure the other two parties to beef up their climate protection policy.
