The EU has been left off a provisional lineup for world leaders to tout their new climate targets, after the bloc failed to agree to a plan to cut greenhouse gas emissions by 2035.

The Sept. 24 summit, convened by United Nations Secretary-General António Guterres, is specifically designated for announcements of new goals for cuts to climate pollution that are required under the 2015 Paris Agreement.

But an internally divided EU has failed to agree on that goal, known in U.N. parlance as a nationally determined contribution (NDC).

The absence of the EU, a longtime leader of global climate policy and diplomacy, would be extraordinary. The U.S., which has walked away from global efforts, was also not on the list.

On Thursday, when the U.N. list was published, EU ministers were locked in talks over a “statement of intent,” which they hoped the EU might deliver instead of a hard target.

Given the strict criteria set by the U.N., there was no guarantee this would grant the EU access. China, the largest polluter, was on the list and was expected to announce a new target. Russia was on the list. India, however, was not afforded a platform.

A U.N. official signaled the EU might be given a pass and that the bloc was expected to have “something” to announce on Sept. 24.

“We know that they take climate seriously,” said the official, who was granted anonymity in order to discuss sensitive diplomatic matters. “We know that they are working on their NDC, so we’ve given them the time, but we need them to really continue to be that global leader.”

The European Commission did not immediately respond to a request for comment.
