US vows to cut its emissions at least 50% by 2030 ahead of climate summit


The US has vowed to cut its planet-heating emissions by at least half by the end of the decade, in a ramping up of ambition aimed at rallying other countries to do more to confront the climate crisis. EURACTIV’s media partner, The Guardian Environment, reports.

Ahead of a virtual gathering of dozens of world leaders at a climate summit called by President Joe Biden, which begins on Thursday, the White House said the US will aim to reduce its greenhouse gas emissions by between 50% and 52% by 2030, based on 2005 levels.

This new target, to be formally submitted to the United Nations, represents a stark break from the climate denialist presidency of Donald Trump and will “unmistakably communicate that the United States is back”, according to a White House official who was briefed on the emissions goal. “The United States isn’t going to wait, the costs of delay are too great and our nation is resolved to act right now,” the administration official added.

The US is scrambling to regain international credibility after Trump pulled the country out of the Paris climate agreement. But the Biden administration said it has already helped secure improved emissions reductions from Canada, Argentina and Japan, meaning that, along with new pledges by countries such as the UK, governments that oversee half of the global economy have targets consistent with stopping the planet’s average temperature from rising above 1.5C, a key Paris goal to avoid disastrous climate impacts.

China, the world’s largest carbon polluter, has expressed some scepticism over the US’ return to the climate fold, but the country’s president, Xi Jinping, will attend Biden’s Earth Day climate summit and the White House is confident America retains its clout. “This new target gives us significant leverage to push for climate action abroad,” said the White House official. “Every ton of reductions achieved in the United States has multiplier effect in inspiring climate action overseas.”

Faced with the task of coming up with an ambitious but feasible goal, the new US target doesn’t match that of the UK and the EU but is still among the strongest pledges to date. António Guterres, the secretary general of the UN, said that a 50% reduction by the US was needed to help stop the planet slipping into a climate “abyss”, with scientists warning the world must slash emissions in half by 2030 if it is to curb calamitous heatwaves, wildfires, floods and societal unrest.

The Biden administration has reiterated it wants the US electricity grid to run 100% on clean sources such as solar and wind by 2035 in order to meet its goals and has framed an explosion in renewable energy and electric car production as a boon to American jobs. It has shied away, however, from mandating all vehicles sold by 2035 be zero emission models, despite a letter from the governors of a dozen states, including California and New York, urging the US president to do so.

“It is very ambitious, even if one considers that US greenhouse gas emissions have actually been declining already since 2007,” said Flavio Lehner, a climate scientist at Cornell University, of the new US target. “Is this new pledge enough? Probably not, but this also depends on what other major emitters will do this decade.”

Manish Bapna, the chief executive of the World Resources Institute, said the new US target “should make the world sit up and take note”. Bapna added: “This target will serve as the north star for President Biden’s domestic agenda. It will create a more equitable and prosperous society. The message to other major emitters is loud and clear: it’s your move next.”

Biden, who has called the climate crisis “the biggest existential threat we face”, will use a speech to open the two-day summit, which will feature a parade of leaders including the German chancellor, Angela Merkel, Boris Johnson, the British prime minister, Vladimir Putin, the Russian president, Narendra Modi, the prime minister of India, and Scott Morrison, the prime minister of Australia.

The gathering will be focused on themes such as clean energy innovation and the importance of oceans and forests, with speakers including Pope Francis and Bill Gates, the Microsoft co-founder. A constellation of other names surround the event, with Greta Thunberg, the Swedish climate activist, addressing a US congressional committee on Thursday morning while the Dalai Lama, along with 100 other Nobel prize winners, is calling for a phase out of fossil fuels.

The summit will be just the first in a series of gatherings, including the G7 and G20, that will take place ahead of crucial UN climate talks in Scotland later this year. John Kerry, Biden’s climate envoy, said he hoped 2021 will see countries embrace a shift to clean energy in a transformation that rivals the space age or Industrial Revolution. “This is the greatest moment of transformation of our economy in our lifetime,” Kerry told the Washington Post. “We need to seize it.”

Some climate activists have said Biden needs to do even more, however, pointing out that the US is lagging after four years of Trump and the rest of the world has made scant progress to date in cutting emissions, with greenhouse gases already rising again after a dip last year due to pandemic-related shutdowns.

“While many will applaud the president’s commitment to cut US emissions by at least half by 2030, we have a responsibility to tell the truth – it is nowhere near enough,” said Evan Weber, the political director and co-founder of the Sunrise Movement climate group.

“The science is clear – if the US does not achieve much, much more by the end of this decade, it will be a death sentence for our generation and the billions of people at the frontlines of the climate crisis in the US and abroad.”
