All the World’s Carbon Emissions in One Chart
Two degrees Celsius may not seem like much, but on our planet, it could be the difference between thriving life and a disastrous climate.
Over two centuries of burning fossil fuels have added up, and global decision-makers and business leaders are focusing in on carbon emissions as a key issue.
Emissions by Country
This week’s chart uses the most recent data from Global Carbon Atlas to demonstrate where most of the world’s CO₂ emissions come from, sorted by country.
|Rank||Country||Emissions in 2017 (MtCO₂)||% of Global Emissions|
|#2||🇺🇸 United States||5,269||14.6%|
|#8||🇸🇦 Saudi Arabia||635||1.8%|
|#9||🇰🇷 South Korea||616||1.7%|
|#14||🇿🇦 South Africa||456||1.3%|
|🌐 Top 15||26,125||72.2%|
|🌐 Rest of World||10,028||27.7%|
In terms of absolute emissions, the heavy hitters are immediately obvious. Large economies such as China, the United States, and India alone account for almost half the world’s emissions. Zoom out a little further, and it’s even clearer that just a handful of countries are responsible for the majority of emissions.
Of course, absolute emissions don’t tell the full story. The world is home to over 7.5 billion people, but they aren’t distributed evenly across the globe. How do these carbon emissions shake out on a per capita basis?
Here are the 20 countries with the highest emissions per capita:
Source: Global Carbon Atlas. Note: We’ve only included places with a population above one million, which excludes islands and areas such as Curaçao, Brunei, Luxembourg, Iceland, Greenland, and Bermuda.
Out of the original 30 countries in the main visualization, six countries show up again as top CO₂ emitters when adjusted for population count: Saudi Arabia, the United States, Canada, South Korea, Russia, and Germany.
The CO₂ Conundrum
We know that rapid urbanization and industrialization have had an impact on carbon emissions entering the atmosphere, but at what rate?
Climate data scientist Neil Kaye answers the question from a different perspective, by mapping what percentage of emissions have been created during your lifetime since the Industrial Revolution:
|Your Age||% of Total Global Emissions|
|15 years old||You've been alive for more than 30% of emissions|
|30 years old||You've been alive for more than 50% of emissions|
|85 years old||You've been alive for more than 90% of emissions|
Put another way, the running total of emissions is growing at an accelerating rate. This is best seen in the dramatic shortening between the time periods taken for 400 billion tonnes of CO₂ to enter the atmosphere:
- First period: 217 years (1751 to 1967)
- Second period: 23 years (1968 to 1990)
- Third period: 16 years (1991 to 2006)
- Fourth period: 11 years (2007 to 2018)
In order to be a decarbonised economy by 2050, we have to bend the (emissions) curve by 2020… Not only is it urgent and necessary, but actually we are very nicely on our way to achieving it.

Visualizing China’s Energy Transition in 5 Charts
This infographic takes a look at what China’s energy transition plans are to make its energy mix carbon neutral by 2060.
Visualizing China’s Energy Transition in 5 Charts
In September 2020, China’s President Xi Jinping announced the steps his nation would take to reach carbon neutrality by 2060 via videolink before the United Nations Assembly in New York.
This infographic takes a look at what this ambitious plan for China’s energy would look like and what efforts are underway towards this goal.
China’s Ambitious Plan
A carbon-neutral China requires changing the entire economy over the next 40 years, a change the IEA compares to the ambition of the reforms that industrialized the country’s economy in the first place.
China is the world’s largest consumer of electricity, well ahead of the second place consumer, the United States. Currently, 80% of China’s energy comes from fossil fuels, but this plan envisions only 14% coming from coal, oil, and natural gas in 2060.

According to the Carbon Brief, China’s 14th five-year plan appears to enshrine Xi’s goal. This plan outlines a general and non specific list of projects for a new energy system. It includes the construction of eight large-scale clean energy centers, coastal nuclear power, electricity transmission routes, power system flexibility, oil-and-gas transportation, and storage capacity.
Progress Towards Renewables?
While the goal seems far off in the future, China is on a trajectory towards reducing the carbon emissions of its electricity grid with declining coal usage, increased nuclear, and increased solar power capacity.
According to ChinaPower, coal fueled the rise of China with the country using 144 million tonnes of oil equivalent “Mtoe” in 1965, peaking at 1,969 Mtoe in 2013. However, its share as part of the country’s total energy mix has been declining since the 1990s from ~77% to just under ~60%.
Another trend in China’s energy transition will be the greater consumption of energy as electricity. As China urbanized, its cities expanded creating greater demand for electricity in homes, businesses, and everyday life. This trend is set to continue and approach 40% of total energy consumed by 2030 up from ~5% in 1990.
Under the new plan, by 2060, China is set to have 42% of its energy coming from solar and nuclear while in 2025 it is only expected to be 6%. China has been adding nuclear and solar capacity and expects to add the equivalent of 20 new reactors by 2025 and enough solar power for 33 million homes (110GW).
Changing the energy mix away from fossil fuels, while ushering in a new economic model is no small task.
Up to the Task?
China is the world’s factory and has relatively young industrial infrastructure with fleets of coal plants, steel mills, and cement factories with plenty of life left.
However, China also is the biggest investor in low-carbon energy sources, has access to massive technological talent, and holds a strong central government to guide the transition.
The direction China takes will have the greatest impact on the health of the planet and provide guidance for other countries looking to change their energy mixes, for better or for worse.
The world is watching…even if it’s by videolink.
Visualizing 50+ Years of the G20’s Energy Mix
Watch how the energy mix of G20 countries has evolved over the last 50+ years.
Visualizing 50+ Years of the G20’s Energy Mix (1965–2019)
Over the last 50 years, the energy mix of G20 countries has changed drastically in some ways.
With many countries and regions pledging to move away from fossil fuels and towards cleaner sources of energy, the overall energy mix is becoming more diversified. But shutting down plants and replacing them with new sources takes time, and most countries are still incredibly reliant on fossil fuels.
G20’s Energy History: Fossil Fuel Dependence (1965–1999)
At first, there was oil and coal.
From the 1960s to the 1980s, energy consumption in the G20 countries relied almost entirely on these two fossil fuels. They were the cheapest and most efficient sources of energy for most, though some countries also used a lot of natural gas, like the United States, Mexico, and Russia.
|Country (Energy Mix - 1965)||Oil||Coal||Other|
|🇸🇦 Saudi Arabia||98%||0%||2%|
|🇿🇦 South Africa||19%||81%||0%|
|🇰🇷 South Korea||20%||77%||3%|
But the use of oil for energy started to decrease, beginning most notably in the 1980s. Rocketing oil prices forced many utilities to turn to coal and natural gas (which were becoming cheaper), while others in countries like France, Japan, and the U.S. embraced the rise of nuclear power.
This is most notable in countries with high historic oil consumption, like Argentina and Indonesia. In 1965, these three countries relied on oil for more than 83% of energy, but by 1999, oil made up just 55% of Indonesia’s energy mix and 36% of Argentina’s.
Even Saudi Arabia, the world’s largest oil exporter, began to utilize oil less. By 1999, oil was used for 65% of energy in the country, down from a 1965 high of 97%.
G20’s Energy Mix: Gas and Renewables Climb (2000–2019)
The conversation around energy changed in the 21st century. Before, countries were focused primarily on efficiency and cost, but very quickly, they had to start contending with emissions.
Climate change was already on everyone’s radar. The UN Framework Convention on Climate Change was signed in 1992, and the resulting Kyoto Protocol aimed at reducing greenhouse gas emissions was signed in 1997.
But when the Kyoto Protocol went into effect in 2005, countries had very different options available to them. Some started to lean more heavily on hydroelectricity, though countries that already utilized them like Canada and Brazil had to look elsewhere. Others turned to nuclear power, but the 2011 Fukushima nuclear disaster in Japan turned many away.
This is the period of time that renewables started to pick up steam, primarily in the form of wind power at first. By 2019, the G20 members that relied on renewables the most were Brazil (16%), Germany (16%), and the UK (14%).
|Country (Energy Mix - 2019)||Natural Gas||Nuclear||Hydroelectric||Renewables||Other|
|🇸🇦 Saudi Arabia||37%||0%||0%||0%||63%|
|🇿🇦 South Africa||3%||2%||0%||2%||93%|
|🇰🇷 South Korea||16%||11%||0%||2%||71%|
However, the need to reduce emissions quickly made many countries make a simpler switch: cut back on oil and coal and utilize more natural gas. Bituminous coal, one of the most commonly used in steam-electric power stations, emits 76% more CO₂ than natural gas. Diesel fuel and heating oil used in oil power plants emit 38% more CO₂ than natural gas.
As countries begin to push more strongly towards a carbon-neutral future, the energy mix of the 2020s and onward will continue to change.
