Biden: Halve Greenhouse Gases by 2030  04/21 06:10

   President Joe Biden will pledge to cut U.S. greenhouse gas emissions at 
least in half by 2030 as he convenes a virtual climate summit with 40 world 
leaders, according to three people with knowledge of the White House plans.

   WASHINGTON (AP) -- President Joe Biden will pledge to cut U.S. greenhouse 
gas emissions at least in half by 2030 as he convenes a virtual climate summit 
with 40 world leaders, according to three people with knowledge of the White 
House plans.

   The 50% target would nearly double the nation's previous commitment and help 
the Biden administration prod other countries for ambitious emissions cuts as 
well. The proposal would 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.

   The nonbinding but symbolically important pledge is a key element of the 
two-day summit, which begins Thursday as world leaders gather online to share 
strategies to combat climate change.

   The emissions target has been eagerly awaited by all sides of the climate 
debate. It will signal how aggressively Biden wants to move on global warming, 
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 three people who know about the White House plans spoke on condition of 
anonymity on Tuesday because they were not authorized to discuss the pledge 
ahead of Biden's announcement.

   Biden has sought to ensure that the 2030 goal, known as a Nationally 
Determined Contribution, or NDC, is aggressive enough to have a tangible impact 
on climate change efforts -- not only in the U.S. but throughout the world -- 
while also being achievable under a closely divided Congress.

   The climate target is a key requirement of the 2015 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.

   Scientists, environmental groups and even business leaders had called on 
Biden to set a target that would cut U.S. greenhouse gas emissions by at least 
50% below 2005 levels by 2030.

   "Wow. That's ambition with a capital A," Georgia Tech climate scientist Kim 
Cobb said Tuesday after learning of Biden's plans. "That target would put us 
roughly in line with the most ambitious emissions reductions targets" projected 
by scientists and environmentalists.

   Cobb, like other experts, said details of Biden's strategy will be crucial, 
"because those details will likely determine whether this ambitious new goal 
can be translated into policy. The clock is ticking fast, environmentally and 

   Pennsylvania State University climate scientist Michael Mann said the 50% 
goal "is precisely what is needed ... an actionable goal within the next decade 
that puts us on the path toward limiting warming below a catastrophic 1.5 
degrees Celsius'' globally.

   The climate summit that Biden is hosting is among his first international 
actions since the United States officially returned to the Paris accord. The 
U.S. withdrawal from the global pact under former President Donald Trump was 
part of Trump's effort to step away from global allegiances in general and his 
oft-stated but false view that global warming was a hoax or at least an 
overstated claim by the world's scientists.

   Biden, by contrast, has made action on climate change a centerpiece of his 
presidency. He has also paused new oil and gas drilling on federal lands and 
proposed a $2.3 trillion infrastructure plan that would remake the U.S. power 
grid and add 500,000 charging stations for electric vehicles, among other 
actions intended to sharply cut fossil fuel pollution that contributes to 
global warming.

   The summit is "the starting gun for climate diplomacy" after a four-year 
"hiatus" under Trump, said Larsen, now a director at the Rhodium Group, an 
independent research firm.

   Former Secretary of State John Kerry, Biden's top climate envoy, has been 
pressing global leaders, including his counterpart in China, for commitments 
and alliances on climate efforts.

   Sen. Ed Markey, a Massachusetts Democrat who reintroduced the Green New Deal 
on Tuesday with Rep. Alexandria Ocasio-Cortez, D-N.Y., said the 50% target was 
appropriate to meet the scope and scale of the climate crisis.

   "The United States must be an undeniable global leader in climate action,'' 
Markey said Tuesday. "We cannot preach temperance from a barstool and not pay 
our fair share when approximately 40% of all the excess carbon dioxide in the 
atmosphere is red, white and blue.''

   A 50% reduction by 2030 is "technically feasible and well within our 
reach,'' Markey added. "We can and should fight to pass legislation and deploy 
funding that will allow us to exceed that target.''

   Sen. John Barrasso, R-Wyo., the top Republican on the Senate Energy 
Committee, said Biden's pledge would set "punishing targets" for the U.S. even 
as adversaries such as China and Russia "continue to increase emissions at 
will. The last thing the economy needs is higher energy prices and fewer jobs, 
but that's exactly what we're going to get.''

   Like other nations, the U.S. goal includes methane and some 
hydrofluorocarbon gases that trap more heat but don't last as long as carbon 

   The 50% pledge was first reported by The Washington Post.
