Italy's premier Giuseppe Conte on Thursday lauded America’s "fantastic" return to the landmark Paris accord to fight climate change - the centrepiece of a flurry of executive orders signed by Joe Biden on the first day of his presidency.
"President Joe Biden rejoining the Paris Agreement is fantastic news," Conte tweeted.
"As G20 President and co-chair of (the UN climate summit) COP26 , Italy looks forward to working with the US to build a sustainable planet and ensure a better future for the next generations," the tweet continued.
Biden's executive action, signed ion Wednesday t the White House within hours of his inauguration as president, will see the US rejoin the Paris accord after a 30-day notice period.
Biden's predecessor, Donald Trump withdrew the US - the world’s second largest emitter of greenhouse gases - from the Paris deal in November, arguing it was too costly.
Under the 2015 agreement, countries pledged to limit the global temperature increase to 1.5C above the pre-industrial era.
