India, the world’s third-biggest emitter, has yet to follow China, the U.S. and the European Union in setting a target for reaching “net zero” emissions. Negotiators are hoping Modi will announce such a goal in Glasgow. The G-20 countries represent more than three-quarters of the world’s climate-damaging emissions and summit host Italy, and Britain, which is hosting the Glasgow conference, had been hoping for more ambitious targets coming out of Rome.

Rather than a quick fix, “Glasgow is the beginning of this decade race, if you will,” Biden’s climate envoy, John Kerry, told reporters Sunday.

The Biden administration has tried hard to temper expectations that two weeks of climate talks will produce major breakthroughs on cutting climate-damaging emissions.
