Climate Action Tracker (CAT) – the nonprofit analytical group that tracks government climate action – studied the numbers and found that, if fulfilled, the Biden plan would reduce greenhouse gas emissions by about 75 gigatons of carbon dioxide by 2050. Warming Global rate of 0.1 ° C by the end of the century.
But the United States cannot do this alone.
To ensure that the 1.5 ° C target is within reach, China needs to fulfill its pledge to abandon carbon by 2060, and the European Union, Japan and South Korea must fulfill their climate commitments.
It’s a huge achievement, but one work that experts say is now within the planet’s grasp.
“This could be a historic turning point: With Biden elected, China, the United States, the European Union, Japan and South Korea – two-thirds of the global economy and more than 50% of global greenhouse gas emissions – net greenhouse gas emissions will be zero. By mid-century, Bill said.” Hare, CEO of Climate Analytics, a partner organization at CAT, said in a statement.
“These commitments are very close, if not within, coherent tracks of 1.5 degrees Celsius for this group of countries and for the first time ever that put the Paris Agreement limit of 1.5 degrees Celsius close by.”
The Paris Agreement, an agreement signed into force in 2016 by nearly all countries in the world, seeks to limit global warming to below 2 ° C and pursue efforts to reduce 1.5 ° C.
Biden pledged to return to the Paris climate agreement – which President Donald Trump left – on his first day in office, then through a “major diplomatic push” that seeks to “raise the ambitions of countries’ climate goals.”
He has laid out a climate action roadmap to restore Covid-19 that includes investments in infrastructure, the automobile industry, transit, the energy sector, building modernization, housing, innovation, agriculture and environmental conservation, and environmental justice.
He is no longer a leader
CAT said the United States is joining a “wave” of countries around the world that now support net-zero greenhouse gas emissions by mid-century, including 127 countries that account for 63% of global emissions.
“What can other countries do now other than follow this overwhelming trend in net greenhouse gas emissions?” Said Niklas Hoon of NewClimate, a partner organization of CAT.
The climate analysis team acknowledged that there was “a great deal of uncertainty” surrounding their estimates. They include the potential for indirect impacts – whether other countries follow suit – and what greenhouse gases are included in the pledges – carbon dioxide or all greenhouse gas emissions.
Biden could also face stiff opposition to his climate goals from opposition lawmakers, and his ability to fully implement his climate plan could depend on the majority party in the Senate.
However, Hare said that while Biden had a lot of work to do, he would “surf a new wave of global ambition.”
Experts say the United States can now take the lead again in climate negotiations and use its leverage to pressure other polluting nations to ramp up their climate ambitions.
To become a credible leader again, the United States will have to demonstrate that it implements these domestic climate policies, and decides what role it will play in bringing the world together on climate solutions, he told CNN last month.
“I think it does this in a number of different ways. It does so by participating in technical assistance programs for developing countries. It does so by creating important alliances around strong political action,” Pershing said. “It is not good to say that I promise you the following.”
