KEY POINTS
  • A razor-thin Democratic Senate majority limits the possibility for Biden to achieve sweeping climate change reform to curb carbon emissions.
  • Sen. Joe Manchin, who has defended coal production in his state, is the incoming chairman of the Senate Energy Committee and will yield major power in deciding what passes.
  • Without new climate legislation from Congress, Biden's orders to reverse Trump's rollbacks on emissions from vehicles, power plants and oil and gas drilling could be undone.
U.S. President Joe Biden delivers remarks on tackling climate change prior to signing executive actions in the State Dining Room at the White House in Washington, January 27, 2021.

President Joe Biden has passed an early flurry of executive action on climate change during his first weeks in office, reversing environmental rollbacks from the Trump administration and quickly acting on campaign promises to address global warming.

The president's orders, though significant, don't substitute for the administration's plans to implement more permanent climate legislation, including parts of the $2 trillion proposal to cut planet-warming carbon emissions to zero by 2035 and achieve net-zero emissions by 2050.
