Democratic presidential candidate Joe Biden on Tuesday laid out an ambitious climate plan that would seek to spend $2 trillion in his first term as president investing in clean-energy infrastructure while vowing to cut carbon emissions from electrical power to zero in 15 years.
The plan signifies a more aggressive approach on climate policy than he adopted during the Democratic presidential primary - a nod to progressives within the party who have been clamoring for swift action.
Biden frequently refers to climate change as "an existential threat" and had faced pressure from the left to adopt more expansive policies.
His revised climate plan would require the country to be producing 100% clean electricity by 2035, moving up his original target date by 15 years - a timeline borrowed from former presidential candidates Jay Inslee and Elizabeth Warren.
Biden also would spend more money more quickly, calling for $2 trillion in new spending over four years, according to a copy of the plan released by his campaign. He had originally suggested spending $1.7 trillion over a decade.
