Carbon dioxide (CO2) emissions from human actions at the moment are larger than at any level in our historical past. In truth, current information reveals that international CO2 emissions have been 182 instances larger 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 information from WRI’s Climate Watch platform. Along with international locations’ historic emissions tendencies, we checked out main drivers of accelerating emissions, similar to inhabitants development, financial improvement and power use.
For context, the UK was the world’s largest CO2 emitter in 1850, the primary yr of accessible information. Its emissions have been almost six instances these of america, 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 information obtainable — China ranked because the world’s largest CO2 emitter, adopted by america, India, Russia and Japan. Nevertheless, among the many top 10 CO2 emittersamerica has the best emission per individual. Per capita emissions within the U.S. are double these of China and eight instances these of India.
See How the High Emitting Nations and Areas Have Shifted Over Time
Most international locations have seen their carbon emissions balloon over time as their populations and economies have grown. Nevertheless, these trajectories look fairly totally different all through totally different moments in historical past. Learn on for a visible recap of some nationwide, regional and international CO2 emissions milestones over the previous 172 years.
From 1850 to the mid-Twentieth century, the world skilled near-constant development in emissions. This was due largely to industrialization and inhabitants development in america and Europe. The U.S. turned the highest CO2 emitter in 1887 and noticed the best acceleration in emissions over the following 9 many years, adopted by the United Kingdom and Germany.
This pattern was sometimes interrupted by historic occasions, just like the Nice Melancholy within the Nineteen Thirties and the tip of World Battle II in 1945. However the ensuing emissions reductions have been solely non permanent. Nations in North America and Europe continued to dominate international emissions by means of the primary half of the century. Because of this, the U.S. and EU stay the most important cumulative emitters thus far, bearing accountability for many CO2 within the environment.
From the Fifties to Nineteen Eighties, Russia additionally skilled fast emissions development. Nevertheless, 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 whole CO2 emissions round 1970.
Whereas the United States stored its place as the highest CO2 emitter all through the Twentieth century, Asian international locations started to emerge onto the scene, led by China.
Since then, China’s economic system has continued to increase quickly — together with its consumption of fossil fuels. China surpassed the U.S. because the world’s prime CO2 emitter in 2005.
An analogous image emerges when emissions by area. East Asia and the Pacific turned the highest regional emitter in 2004. By 2022, it was contributing 44% of worldwide CO2 emissions. Europe and Central Asia and North Americathe next-highest emitting areas, accounted for 17% and 15% respectively. Nevertheless, this solely represents whole annual emissions.
Relating to per capita emissions, North Americastays the best by far, adopted by Europe and Central Asia. Nevertheless, 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 best whole, adopted by North America. However East Asia and the Pacific is quickly catching up right here, too.

COVID-19 Triggered a Sharp Lower in Emissions, however It Was Brief Lived
The COVID-19 pandemic had a drastic impact on international economies, ensuing within the largest annual drop in CO2 emissions in recorded historical past. In 2020, international emissions fell by 1.5 billion metric tons of carbon dioxide (GtCO2) — an quantity roughly equal to Japan’s CO2 emissions that yr. This was twice the scale 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 shortly as international locations resumed their financial actions, with 2021 surpassing 2019 ranges.
World Per Capita Emissions Have Stabilized Since 2011
The excellent news is that, whereas absolute emissions proceed to rise, international per capita emissions haven’t elevated since 2011. This implies that international locations are regularly transferring away from the earlier carbon-intensive improvement trajectory as they start transitioning in direction of renewable energy, electric vehicles and different clear applied sciences.
Nevertheless, there’s a great distance nonetheless to go. The crucial now’s to reverse course on whole emissions, that are nonetheless rising, to remain on monitor with international local weather commitments to make sure a livable future for all.
The High 10 Emitters Nonetheless Make Up 76% of World Carbon Emissions
Originally of our timeline in 1850, only a small variety of international locations have been accountable for almost all of worldwide emissions. In 2022, the most important gamers have modified, however the prime 10 emitters nonetheless contribute 76% of worldwide CO2 emissions.
Whereas all international locations might want to work collectively to sort out the local weather disaster, this comparatively small group of countries carries an outsized share of the accountability for inflicting it. These international locations 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, international locations must quickly cut back emissions to net zero by 2050. Local weather information is crucial to understanding how we’ve come to be on this state of disaster, the most recent emissions tendencies, and what actions international locations should absorb each the quick and long run to bend the emissions curve downward.
Climate WatchWRI’s local weather information platform, provides a whole lot of open datasets that visualize historical greenhouse gas emissions of all international locations, areas, sectors and varied forms of greenhouse gasses. The platform permits customers to analyze and compare international locations’ nationally decided contributions (NDCs) and long-term Methods (LTS) below the Paris Settlement; discover local weather insurance policies; see how nations can leverage their climate goals to attain sustainable improvement aims; and use fashions to map new pathways to a lower-carbon, affluent future.
Editor’s be aware: This text was initially printed in 2014. It was up to date in June 2024 with the most recent information on international carbon dioxide emissions from Local weather Watch.
1 CO2 is just not the one greenhouse fuel 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.
