Germany's Green Party voted on Sunday to join formal talks to be part of the country's next ruling coalition government.
The climate-friendly party came third in Germany's election on September 26, but is a kingmaker in forming the next government.
The center-left Social Democratic Party (SPD) won the largest share of the vote and has been holding preliminary talks with the Greens and the business-focused Free Democratic Party (FDP) for the past week.
On Friday, the leaders of the SPD, Greens and FDP wrapped up exploratory coalition talks and agreed to proceed further, subject to approval by each of the parties' senior officials.
Preliminary talks focused on energy transition
An exploratory paper presented Friday described how the three parties were committed to climate protection to bring Germany toward the goals of the 2015 Paris climate accord.
In addition, Germany's phaseout of coal, currently envisaged by 2038 at the latest, should "ideally" be brought forward to 2030, said the paper.
While all three parties have already come out in favor of formal talks to form a coalition, Sunday's meeting saw Green Party delegates officially approve the move.
FDP to seek party approval next week
The Social Democrats formally approved the step on Friday, while the FDP leadership is set to do so on Monday.
The would-be alliance is described as the "traffic light" coalition — the colors of the three parties' logos.
The SPD is currently in a grand coalition with Chancellor Angela Merkel's conservative bloc, but has said it would prefer a new alliance with the Greens and FDP, rather than maintain the status quo.
Merkel decided not to run for chancellor again after 16 years in power.
Support for her center-right alliance dropped in the election after the party's candidate, Armin Laschet, failed to connect with voters.
