The US Senate approved a $1trn infrastructure bill with broad bipartisan support on Tuesday, allocating significant funding to upgrade America's power grid but with significantly less to address climate change than earlier proposed by President Joe Biden – and no renewable energy tax credits.

Nineteen opposition Republicans including minority leader Mitch McConnell joined all 48 Democrats and two independents in a 69-30 vote to approve the measure that advances a core piece of Biden's 'Build Back Better' economic agenda.
