Carbon dioxide (CO2) emissions from human actions at the moment are greater than at any level in our historical past. In reality, latest knowledge reveals that world CO2 emissions have been 182 occasions greater in 2022 than they have been in 1850, across the time the economic revolution was underway.1
How did we arrive at such an unprecedented and precarious state? To reply this and different key questions, we analyzed the most recent emissions knowledge from WRI’s Local weather Watch platform. Along with nations’ historic emissions tendencies, we checked out main drivers of accelerating emissions, comparable to inhabitants progress, financial growth and vitality use.
For context, the UK was the world’s largest CO2 emitter in 1850, the primary 12 months of accessible knowledge. Its emissions have been almost six occasions these of the US, the second-ranked nation on the time. France, Germany and Belgium accomplished the record of the highest 5 emitters.
As of 2022 — the most recent knowledge accessible — China ranked because the world’s largest CO2 emitter, adopted by the US, India, Russia and Japan. Nonetheless, among the many high 10 CO2 emitters, the US has the very best emission per particular person. Per capita emissions within the U.S. are double these of China and eight occasions these of India.
See How the Prime Emitting International locations and Areas Have Shifted Over Time
Most nations have seen their carbon emissions balloon over time as their populations and economies have grown. Nonetheless, these trajectories look fairly completely different all through completely different moments in historical past. Learn on for a visible recap of some nationwide, regional and world CO2 emissions milestones over the previous 172 years.
From 1850 to the mid-Twentieth century, the world skilled near-constant progress in emissions. This was due largely to industrialization and inhabitants progress in the US and Europe. The U.S. turned the highest CO2 emitter in 1887 and noticed the best acceleration in emissions over the subsequent 9 a long time, adopted by the United Kingdom and Germany.
This development was sometimes interrupted by historic occasions, just like the Nice Melancholy within the Thirties and the tip of World Warfare II in 1945. However the ensuing emissions reductions have been solely non permanent. International locations in North America and Europe continued to dominate world emissions by means of the primary half of the century. Because of this, the U.S. and EU stay the biggest cumulative emitters thus far, bearing duty for many CO2 within the environment.
From the Fifties to Eighties, Russia additionally skilled fast emissions progress. Nonetheless, its emissions dropped off considerably with the dissolution of the Soviet Union.
For comparability, the U.Ok., as soon as the world’s highest emitter, stabilized its complete CO2 emissions round 1970.
Whereas the United States saved its place as the highest CO2 emitter all through the Twentieth century, Asian nations started to emerge onto the scene, led by China.
Since then, China’s economic system has continued to broaden quickly — together with its consumption of fossil fuels. China surpassed the U.S. because the world’s high CO2 emitter in 2005.
The same image emerges when taking a look at emissions by area. East Asia and the Pacific turned the highest regional emitter in 2004. By 2022, it was contributing 44% of world CO2 emissions. Europe and Central Asia and North America, the next-highest emitting areas, accounted for 17% and 15% respectively. Nonetheless, this solely represents complete annual emissions.
On the subject of per capita emissions, North America, stays the very best by far, adopted by Europe and Central Asia. Nonetheless, East Asia and the Pacific may be very near changing into the second largest per-person emitter.
cumulative emissions since 1850, Europe and Central Asia nonetheless have the very best complete, adopted by North America. However East Asia and the Pacific is quickly catching up right here, too.

COVID-19 Induced a Sharp Lower in Emissions, however It Was Brief Lived
The COVID-19 pandemic had a drastic impact on world economies, ensuing within the largest annual drop in CO2 emissions in recorded historical past. In 2020, world emissions fell by 1.5 billion metric tons of carbon dioxide (GtCO2) — an quantity roughly equal to Japan’s CO2 emissions that 12 months. This was twice the dimensions of the 1992 drop following the dissolution of the Soviet Union (the second largest emissions drop in recorded historical past). Nonetheless, it was non permanent. Emissions bounced again rapidly as nations resumed their financial actions, with 2021 surpassing 2019 ranges.
International Per Capita Emissions Have Stabilized Since 2011
The excellent news is that, whereas absolute emissions proceed to rise, world per capita emissions haven’t elevated since 2011. This implies that nations are regularly transferring away from the earlier carbon-intensive growth trajectory as they start transitioning in direction of renewable vitality, electrical autos and different clear applied sciences.
Nonetheless, there’s a good distance nonetheless to go. The crucial now’s to reverse course on complete emissions, that are nonetheless rising, to remain on observe with world local weather commitments to make sure a livable future for all.
The Prime 10 Emitters Nonetheless Make Up 76% of International Carbon Emissions
At first of our timeline in 1850, only a small variety of nations have been accountable for almost all of world emissions. In 2022, the key gamers have modified, however the high 10 emitters nonetheless contribute 76% of world CO2 emissions.
Whereas all nations might want to work collectively to deal with the local weather disaster, this comparatively small group of countries carries an outsized share of the duty for inflicting it. These nations must step up their local weather management by quickly lowering emissions and supporting different nations of their transitions in direction of a lower-carbon economic system.
Discover the Newest Carbon Emissions Information
To keep away from the worst impacts of local weather change, nations must quickly cut back emissions to web zero by 2050. Local weather knowledge is crucial to understanding how we’ve come to be on this state of disaster, the most recent emissions tendencies, and what actions nations should soak up each the brief and long run to bend the emissions curve downward.
Local weather Watch, WRI’s local weather knowledge platform, provides a whole lot of open datasets that visualize historic greenhouse gasoline emissions of all nations, areas, sectors and numerous forms of greenhouse gasses. The platform permits customers to analyze and evaluate nations’ nationally decided contributions (NDCs) and long-term Methods (LTS) below the Paris Settlement; discover local weather insurance policies; see how nations can leverage their local weather targets to realize sustainable growth aims; and use fashions to map new pathways to a lower-carbon, affluent future.
Editor’s notice: This text was initially revealed in 2014. It was up to date in June 2024 with the most recent knowledge on world carbon dioxide emissions from Local weather Watch.
1 CO2 is just not the one greenhouse gasoline and short-term motion on methane and different short-lived pollution are important to deal with local weather change. CO2 represents about three-quarters of annual emissions and estimates can be found ranging from 1850, permitting us to discover an extended historical past of carbon dioxide emissions.
