An analysis shows President Joe Biden’s climate summit and the run-up to it cut the so-called emissions gap, a crucial measurement used to see if the world can limit global warming, by about one-eighth, AP reports.

Climate Action Tracker is a group of scientists who monitor nations’ pledges of carbon pollution cuts. It calculated that targets announced since last September cut about 12 percent to 14 percent from the emissions gap.

That emissions gap is that big area between what nations promise to do and the pollution reductions needed by 2030 to limit future warming to another half a degree, which is the stricter of two goals adopted by the 2015 Paris climate deal.

The tracker calculated the announcements cut between 2.9 and 4.1 billion tons of carbon from the gap.

With the new targets from the United States, the United Kingdom, the European Union, Japan and Canada, the new emissions gap is 22 to 26 billion tons of carbon pollution. The tracker says before those pledges it was 25 to 30 billion tons.

Climate scientist Niklas Hohne says “we are now starting to see the kind of near-term climate action the world needs to win the race to zero by 2050.” Hohne says, “While the gap is still huge, the summit created new momentum.”
