Climate Action Tracker (CAT) – a for-profit analysis group that tracks government climate action – reduced the number and saw that, if Biden’s plan is completed, greenhouse gas emissions by about 75 gigatonnes of carbon dioxide will decrease by 2050. By the end of the century, global warming will be 0.1 degrees Celsius.
But the US cannot do that alone.
To ensure the 1.5 degree Celsius target is within reach, China needs to stick to its commitment to go carbon neutral by 2060, and the European Union, Japan and South Korea all need to achieve their weather commitments, the CAT said.
It’s a big feat to pull off, but experts say it’s now in the grip of the planet.
“This could be a historic tipping point: with Biden’s election, China, the US, the EU, Japan, South Korea – more than two-thirds of the world’s economy and over 0% of global greenhouse gas emissions – will be greenhouse gas emissions.” By mid-century commitments, ”said Bill Hare, CEO of CAT partner organization, Climate Analytics, in a statement.
“These commitments are so close, if not within, that this set 1.5 ˚ C-compatible routes for group countries and, for the first time, a shocking distance to the 1.5˚C limit of the Paris Agreement.”
The Paris Agreement, an agreement reached in 2016 by almost all countries in the world, seeks to keep global warming below 2 degrees Celsius and limit it to 1.5 degrees Celsius.
Biden has promised to re-enter the Paris Climate Agreement – which was abandoned by President Donald Trump – and first through major business pressure to “try to raise the ambitions of countries’ climate goals.”
He laid out a Climate Action Roadmap for the recovery of Covid-19, which includes infrastructure, auto industry, transportation, power sector, housing improvement and veterinary, housing, innovation, agriculture and defense, and environmental justice.
There is no leader now
The CAT said the U.S. now supports net-zero greenhouse gas emissions by the middle of the century, with 12 of the world’s 12 countries accounting for 63% of global emissions.
“What can other countries do now except follow this overwhelming trend of zero-zero greenhouse gas emissions?” Said Niclas Hahn of the Nuclear Climate Institute, a CAT partner organization.
The weather analysis group acknowledged that there was “significant uncertainty” around their estimates. These include the possibility of spill-over effects – whether other countries are favorable – and which greenhouse gases are included in the pledge – carbon dioxide or all planet-warming emissions.
Biden may also face strong opposition from opposition lawmakers to their climate goals, and his ability to fully implement his climate plan depends on which party controls the majority in the Senate.
Still, Hare said, while Biden has a lot of work ahead of him, “he will surf a new wave of global ambition.”
Experts say the U.S. Now the weather can take a new lead in negotiations and use its influence to force other polluting countries to increase their own environmental ambitions.
To become a credible leader again, the U.S. It will have to prove that it is implementing local climate policies and determine what role it will play in bringing the world together around climate solutions.
“I think he does it in a lot of ways. He does it by participating in technical assistance programs for developing countries. He does it by making important connections around strong policy actions,” Pursing said. “It’s not so good to say I promise you the following.”
