NEW YORK/TOKYO -- A two-day, virtual climate summit hosted by U.S. President Joe Biden kicked off Thursday, with world leaders promising to take concrete actions to secure a greener future.
"The United States sets out on the road to cut greenhouse gases in half by the end of this decade," Biden said in his opening speech from the White House. A fact sheet released earlier announced a target of a 50%-52% cut from its 2005 level by 2030.
