How much are countries pledging to reduce emissions?

As the United Nations climate summit in Glasgow, Scotland, gets underway this week, many countries have vowed to do more to fight climate change. Yet those plans still fall short of what’s needed to avoid a dangerous rise in global temperatures.

Data from Climate Action Tracker reveals emissions pathways for the world’s 10 biggest polluters. They account for more than two-thirds of greenhouse gas emissions.

Major emitters

In the run-up to the summit, the United States and the European Union made new vows to cut their emissions roughly 50% below 2005 levels by 2030. But neither has yet enacted sufficient policies to meet those pledges. European nations are debating a large new clean-energy package, while the Biden administration is still trying to push major climate legislation through Congress.
