For leaders abroad, new U.S. law restores climate credibility

The U.S. climate bill signed into law this week restores the country's credibility as a leading player in U.N. climate negotiations, international officials said. The $430 billion bill passed by President Joe Biden on Tuesday, after more than a year of tense negotiations, lays out policies and investments to curb greenhouse gas emissions in the world's largest historical emitter. Research suggests the measures could result in reducing U.S. emissions to about 40% below 2005 levels by 2030 - not quite the 50% reduction Biden had pledged under last year's Glasgow Climate Pact.
