The Cilimate Pledge
of the World’s top Emitters
Under the Paris climate agreement, nearly every country is to drastically reduce their carbon emissions, and they were supposed to submit renewed plans to do so by the end of 2020.
The first raft of “nationally determined contributions” (NDCs) submitted in 2015 would put Earth on course to be at least 3 degrees Celsius hotter than pre-industrial times, a far cry from the Paris temperature cap goal of keeping warming “well below” 2°C. Under the deal’s “ratchet” mechanism, signatories are required to periodically renew their emission-cutting plans to drive more rapid decreases in emissions. Roughly half of countries met the 2020 deadline to do so, but many big emitters – including the top two, China and the United States – have yet to do so. Washington has said it will unveil its new targets soon, in anticipation of the delayed COP26 summit in Glasgow in November.
In its first NDC, China – by far the largest emitter, responsible for roughly a quarter of all carbon pollution – promised to reduce the intensity of its emissions by as much as 65 percent by 2030.
Under that scenario, it planned to reach peak emissions at the end of this decade. In September last year, President Xi Jinping made a surprise announcement at the UN General Assembly: China plans to achieve net-zero emissions by 2060.
But the country’s new five-year plan, released in March, doesn’t spell out the steps to reaching this goal, nor has Beijing officially submitted its renewed NDC.
The second-largest polluter, the US was one of the driving forces behind the Paris deal, with an initial commitment to cut emissions a quarter by 2025, compared with 2005 levels.
President Joe Biden wasted no time in office in rejoining the accord after his predecessor Donald Trump’s decision to backtrack on US commitments. He has set a net-zero date for 2050 and has unveiled a $2 trillion infrastructure spending plan to help achieve it.
The EU committed in 2015 to reduce its CO2 emissions by at least 40 percent by 2030 compared to 1990 levels.
Member states updated this goal in December, aiming to reduce emissions by “at least 55 percent” by the end of this decade.
Although Britain has left the EU, it also has a 2050 net-zero target built into law. It announced in December last year that it would seek to reduce emissions 68 percent by 2030, compared with 1990 levels.
Like China, India plans to reduce its carbon intensity — by up to 35 percent this decade compared to 2005 levels.
The world’s third-largest polluter has yet to submit a renewed NDC.
Russia formally rejoined the Paris deal in 2019. Moscow says it plans to achieve pollution levels in 2030 that are 70 percent of 1990 levels — in reality a drop of only 30 percent.
Japan in 2016 committed to a 26-percent reduction in emissions by 2030. Its renewed NDC, issued in March 2020, had the same figure, eliciting sharp criticism from carbon monitoring research groups.
However new Prime Minister Yoshihide Suga said in October last year that the country would be carbon neutral by 2050.
