WASHINGTON, D.C. — As President Joe Biden convenes a virtual climate summit on Thursday with 40 world leaders, he faces a vexing task: how to put forward a nonbinding but symbolic goal to reduce greenhouse gas emissions that will have a tangible impact on climate change efforts not only in the U.S. but throughout the world.
The emissions target, eagerly awaited by all sides of the climate debate, will signal how aggressively Biden wants to move on climate change, a divisive and expensive issue that has riled Republicans to complain about job-killing government overreach even as some on the left worry Biden has not gone far enough to address a profound threat to the planet.
The climate crisis poses a complex political challenge for Biden, since the problem is harder to see and far more difficult to produce measurable results on than either the coronavirus pandemic relief package or the infrastructure bill.
The target Biden chooses “is setting the tone for the level of ambition and the pace of emission reductions over the next decade,” said Kate Larsen, a former White House adviser who helped develop President Barack Obama’s climate action plan.
The number has to be achievable by 2030 but aggressive enough to satisfy scientists and advocates who call the coming decade a crucial, make-or-break moment for slowing climate change, Larsen and other experts said.
Scientists, environmental groups and even business leaders are calling on Biden to set a target that would cut U.S. greenhouse gas emissions by at least 50% below 2005 levels by 2030.
The 50% target, which most experts consider a likely outcome of intense deliberations underway at the White House, would nearly double the nation’s previous commitment and require dramatic changes in the power and transportation sectors, including significant increases in renewable energy such as wind and solar power and steep cuts in emissions from fossil fuels such as coal and oil.
Anything short of that goal could undermine Biden’s promise to prevent temperatures from rising more than 1.5 degrees Celsius, experts say, while likely stirring up sharp criticism from international allies and Biden’s own supporters.
The 2030 goal, known as a Nationally Determined Contribution, or NDC, is a key part of the Paris climate agreement, which Biden rejoined on his first day in office. It’s also an important marker as Biden moves toward his ultimate goal of net-zero carbon emissions by 2050.
“Clearly the science demands at least 50%” in reduced greenhouse gas emissions by 2030, said Jake Schmidt, a climate expert at the Natural Resources Defense Council, a leading environmental group.
The 50% target “is ambitious, but it is achievable,” he said in an interview. It’s also a good climate message, he said: “People know what 50% means — it’s half.”
John Kerry, Biden’s climate envoy, has been pressing global leaders, including his counterpart in China, for commitments and alliances on climate efforts.
Secretary of State Antony Blinken, in a speech Monday, said the U.S. is falling behind China, the largest producer and exporter of solar panels, wind turbines, batteries and electric vehicles.
“If we don’t catch up, America will miss the chance to shape the world’s climate future in a way that reflects our interests and values, and we’ll lose out on countless jobs for the American people,” Blinken said in prepared remarks for a speech in Annapolis, Maryland.
Nathaniel Keohane, another former Obama White House adviser and now a vice president at the Environmental Defense Fund, said his organization has coalesced around the need for the U.S. to reduce emissions by at least 50% by 2030.
“The number has to start with 5,” he said, adding, “We’ve done the math. We need at least 50%.”
Some Republican lawmakers call the focus on reducing U.S. emissions counterproductive, saying Biden’s plan would raise energy costs and kill American jobs while allowing Russia, China and other countries to increase greenhouse gas emissions.
“The Biden administration will set punishing targets for the United States, while our adversaries keep the status quo. That won’t solve climate change,” said Sen. Wyoming Sen. John Barrasso, the top Republican on the Senate Energy Committee. The United States already leads the world in reducing carbon emissions, Barrasso said, adding that Biden should try to “make American energy as clean as we can, as fast as we can, without raising costs for consumers.”
