U.S. President Joe Biden urged world leaders on Friday to join the United States and European Union in a pledge to cut methane emissions, hoping to build momentum before an international summit on climate change begins next month.

Biden held a virtual meeting of the Major Economies Forum (MEF), a follow-up to an Earth Day meeting he hosted in April to unveil new U.S. greenhouse gas emissions reduction targets and press other countries to do more to curb theirs.
