G-20 leaders turn to climate change on last day of summit

Leaders of the world’s biggest economies are set to tackle climate change on the final day of a weekend summit in Rome that is widely expected to set the tone for a major conference on the same issue taking place in Glasgow over the next two weeks

ROME -- Leaders of the world's biggest economies were set to tackle climate change Sunday, the final day of a weekend summit in Rome that is widely expected to set the tone for a major conference on the same issue taking place in Glasgow, Scotland, over the next two weeks.

The Group of 20 countries, which represent more than three-quarters of the world's greenhouse gas emissions, are looking for common ground on how to reduce emissions while helping poor countries deal with the impact of rising temperatures.

If the G-20 summit ends with only weak commitments, momentum could be lost for the larger annual talks in Glasgow, where countries from around the globe will be represented including poor ones most vulnerable to rising seas, desertification and other effects.

The future of coal, a key source of greenhouse gas emissions, has been one of the hardest things for the G-20 to agree on. However, the U.S. and other countries are hoping to get a commitment to end overseas financing of coal-fired power generation, said a senior U.S. official who spoke on condition of anonymity to preview President Joe Biden's plans.
