By 2030, the world will be emitting 51.5 billion metric tons of carbon dioxide each year, 1.5 billion tons less than before the latest pledges. To achieve the limit first set in the 2015 Paris climate accord, which came out of a similar summit, the world can only emit 12.5 billion metric tons of greenhouse gases in 2030.

 The United Nations climate summit in Glasgow has made “some serious toddler steps” toward cutting emissions but far from the giant leaps needed to limit global warming to internationally accepted goals, two new analyses and top officials said Tuesday, AP reports.

And time is running out on the two weeks of negotiations.

The president of the climate talks, Alok Sharma, told high-level government ministers at the U.N. conference to reach out to their capitals and bosses soon to see if they can get more ambitious pledges because “we have only a few days left.”

This month’s summit has seen such limited progress that a United Nations Environment Program analysis of new pledges found they weren’t enough to improve future warming scenarios. All they did was trim the “emissions gap” — how much carbon pollution can be spewed without hitting dangerous warming levels— a few tenths of a percentage point, according to the review released Tuesday.

The analysis found that by 2030, the world will be emitting 51.5 billion metric tons of carbon dioxide each year, 1.5 billion tons less than before the latest pledges.
