China is by far the world’s largest CO2 emitter, with the world’s largest population and one of the fastest rising economies for decades. In 2017, the superpower emitted about 10,000 million metric tons of CO2 from the burning of fossil fuels. China’s CO2 emissions per capita, at 7.1 metric tons per person, are lower than those of the majority of the countries on this list, but they still rank in the top 50 globally.
Driving China’s huge coal production is the source of the country’s CO2 emissions. China’s coal-fired energy generation has decreased marginally from 75% in 1992 to 70% in 2015. Despite this, worldwide coal production has increased by almost 4,000 million metric tons since 2000, accounting for roughly half of total global coal production.

Which country is the largest emitter of greenhouse gases?
China is the world’s greatest source of CO2 emissions, a trend that has climbed consistently over time. A total of 9.9 billion metric tons of CO2 is being produced in the country. Electricityspecifically, coal combustionis the leading source of CO2 emissions in these countries.
Which countries are the top five emitters of greenhouse gases?
In this example, the five main emittersthe United States, the European Union, China, the Russian Federation, and Japantotaled two-thirds of the world’s historic CO2 emissions, consuming roughly 37% of our global carbon budget.
What generates the highest greenhouse gas emissions?
- The energy sector is the source of the greatest amount of greenhouse gas emissions. Energy-related emissions come from a variety of sources, including the electricity and heat used to power homes, manufacturing, building, and transportation.
- Emissions are also produced by industrial operations that are unrelated to energy generation. For example, greenhouse gases are released during the manufacture of cement and glass, as well as household items such as soap and detergent. Furthermore, the extraction of fossil fuels such as oil or natural gas produces emissions during the industrial process.
- Emissions are produced by agricultural sources such as farming, including manure management, fertilizers, field burning, and farm fuel consumption. In fact, animals belching account for nearly a third of agricultural emissions: when a cow burps, it emits methane gasand cows burp a lot.
- Land-use Deforestation is an example of climate change and forestry. In two ways, deforestation contributes to higher emissions. The equipment that fell and processed trees consume fossil fuels, which emit greenhouse gases. Cutting down trees limits the earth’s ability to absorb additional carbon emissions because trees require carbon dioxide during photosynthesis.
- Incineration and landfilling are two waste disposal methods that release greenhouse gases. Organic material in landfills, for example, produces methane as it decomposes.
- Bunker fuel is used to power ships and planes. The thick, viscous oil left behind after crude oil goes through the refining process to produce diesel and gasoline is known as kerosene. Only huge, complicated engines, such as those used on ships, can sufficiently heat bunker fuel to cause it to ignite.
Companies: Which companies are the top emitters of greenhouse gases?
Now that we’ve looked at which countries and industries emit the most greenhouse gases, we can look at emissions in a way that integrates the two. We can investigate how businesses, both private and public, contribute to climate change.
The amount of greenhouse gases created during the process of extracting oil from the earth and the burning of all that oil by customers who use it to power their automobiles or generate electricity, for example, are combined in the amount of emissions displayed on the chart for each oil business.
Who has made the most contribution to global CO2 emissions?
The globe has emitted about 1.5 trillion tonnes of CO2 since 1751. 2 To meet our climate objective of limiting average temperature rise to 2C, the globe must reduce emissions as soon as possible. One prevalent argument is that the countries that have contributed the most CO2 to our environment and thus are the most responsible for the problem now should bear the brunt of the burden in addressing it.
By looking at cumulative CO2, we may compare each country’s total contribution to world emissions. By adding together each country’s annual CO2 emissions over time, we may determine cumulative emissions. From 1751 to 2017, we calculated this for each country and region. 3
The treemap depicts the distribution of cumulative emissions over the earth. Treemaps are used to compare entities (such as countries or regions) to one another and to the overall population. Countries are shown as rectangles that are colored by region. Each rectangle’s size represents the total CO2 emissions from a country between 1751 and 2017. The total of all rectangles is the global total.
- Since 1751, the United States has emitted more CO2 than any other country, accounting for about 400 billion tonnes, or 25% of all historical emissions.
- This is more than twice as much as China, the world’s second-largest supplier.
- The European Union (EU-28) which is included together here since they normally discuss and establish targets together is also a significant historical contributor, accounting for 22%;
- Many of today’s major annual emitters, such as India and Brazil, were not historically significant contributors.
- Africa’s regional contribution has been negligible in comparison to its population size. This is due to historically and currently extremely low per capita emissions.

Between 1850 and 2014, which country emitted the most greenhouse gases?
Editor’s note: This blog’s data and visualizations have been changed to use Climate Watch instead of the CAIT Climate Data Explorer as of March 31, 2021.
Human-caused carbon dioxide (CO2) emissions are now higher than at any other time in history. In fact, according to latest estimates, global CO2 emissions in 2011 were 150 times more than they were in 18501.
How did we get up in such an unusual and perilous situation? Climate Watch continues to be updated with CO2 emissions estimates, offering a rich data set that chronicles global emissions growth through time. The data also reveals information on associated trends and emissions causes, such as population increase, economic development, and energy use.
For background, the United Kingdom was the largest CO2 emitter at the start of this period (1850), with emissions approximately six times those of the second-highest emitter, the United States. The top five emitters were completed by France, Germany, and Belgium. China was the world’s greatest emitter in 2011, followed by the US, India, Russia, and Japan. While the US was the world’s second-largest emitter in both years, its emissions in 2011 were 266 times higher than in 1850.
Other nations have followed similar paths, gradually increasing their emissions. Those trajectories, however, appear to be significantly different at various points in history. Continue reading for a visual timeline of some of the most significant national, regional, and global CO2 emissions milestones in the last 160 years.
: Industrializing Countries Dominate Emissions
Between 1850 and 1960, the world’s emissions increased steadily, owing mostly to industrialization and population growth, especially in the United States. Historic events such as the Great Depression in the 1930s and the end of World War II in 1945 only slowed this progression. China and Russia, on the other hand, began to see their emissions rise as their economies boomed in the 1950s.
: New Top Emitters Emerge
After 1960, we noticed several new breakthroughs. While the United States remained the leading CO2 emitter until 2005, Asian countries, led by China, began to emerge. Since 1960, the development of the current top five CO2-emitting countries has been depicted in the graph above, with the United Kingdom serving as a point of comparison. The United Kingdom, which was previously the world’s leading emitter, has stabilized its total CO2 emissions. With the dissolution of the Soviet Union, Russia saw a considerable reduction in emissions. The rise of China’s emissions in the early twenty-first century, and its subsequent overtaking of the United States as the world’s greatest emitter after 2005, was the most visible development.
: Per Capita Emissions in the WestStable, but High
When we examine these emissions patterns on a per person basis, we can see that, while global emissions continued to rise overall, most industrialized countries’ per capita emissions stabilized in the second half of the twentieth century. Despite sustained emissions rise in these countries, annual per capita emissions in industrialized regions such as North America and Europe were remained significantly more than per capita emissions in Latin America and the Caribbean, Africa, and Asia. Even among the top ten CO2 producers in 2011, per capita emissions varied substantially. Saudi Arabia and the United States, for example, released more than 17 metric tons per person per year, compared to 6.7 and 1.5 metric tons per person per year for China and India, respectively.
s-2011: The Rise of Asia
Asia’s gross domestic GDP surpassed that of the rest of the globe in 1994. However, Asia overtook the United States as the leading CO2 emitter a year earlier, in 1993, owing partly to China’s rapid economic expansion. This huge movement is depicted in the graph above. Europe and Northern America used to account for the majority of world emissions. However, by the end of 2011, Asia had taken over, accounting for more than half of all worldwide CO2 emissions. As indicated in the previous graph, Asia’s per capita emissions are still far lower than those of western regions.
: Developing Nations Surpass Industrialized Countries’ Emissions
The UNFCCC’s Annex I (developed countries) and Non-Annex I (developing countries) divisions demonstrate how swiftly the emissions space altered in the late twentieth and early twenty-first centuries. By 2007, CO2 emissions from developing countries had surpassed those from developed countries. We can see below that if we include all greenhouse gases and emissions resulting from land use change and forestrysuch as deforestation and tree-clearing for agriculturethis event occurs in 2004.
: The Top 10 Emitting Countries Still Make Up 78% of Global CO2 Emissions
The majority of emissions were caused by a small number of emitters at the start of our timeline. Although the countries have changed since 2011, the top ten polluters still account for 78% of worldwide CO2 emissions. The top ten CO2 emitters are depicted in the first graph (excluding land use change and forestry). 2
Data from 2011 is far more abundant than data from previous years. The differences between the two graphs below may be seen when all greenhouse gases are included (including land use change and forestry). Indonesia and Brazil, in particular, were among the top ten polluters, with the land-use change sector accounting for a considerable portion of their national emissions.
While all countries will have to work together to address climate change, we can see that the vast majority of emissions are concentrated in a small number of countries.

We must swiftly cut emissions to net zero by 2050 to avert the worst effects of climate change. Climate data is critical for comprehending recent emissions patterns as well as countries’ short- and long-term activities to bend the emission curve lower.
Climate Watch, the World Resources Institute’s climate data platform, has hundreds of free datasets that show historical greenhouse gas emissions for all countries, regions, industries, and types of greenhouse gases. Users can use the platform to analyze and compare the Paris Agreement’s nationally determined contributions (NDCs) and long-term strategies (LTS), learn about countries’ climate policies, see how countries can use their climate goals to meet their sustainable development goals, and use models to map new pathways to a lower-carbon, prosperous future. These tools can help identify what changes need to be made and map out a path to net zero energy.
What is the most significant contributor to global carbon emissions?
Who is accountable for these emissions and where do they come from? The Climate Watch platform from the World Resources Institute provides complete emissions statistics for all countries, sectors, and gases. Here’s what we know about the industries and countries that are generating global greenhouse gas emissions:
The Energy Sector Produces the Most Greenhouse Gas Emissions
Energy consumption is by far the most significant source of human-caused greenhouse gas emissions, accounting for 76 percent (37.2 GtCO2e) of global emissions. Transportation, electricity and heat, buildings, manufacturing and construction, fugitive emissions, and other fuel combustion are all part of the energy industry.
Agriculture, including livestock and crop cultivation (5.8 GtCO2e, or 12 percent); industrial processes of chemicals, cement, and other materials (2.9 GtCO2e, or 5.9 percent); waste, including landfills and waste water (1.6 GtCO2e, or 3.3 percent); and land use, land-use change, and forestry, including deforestation (1.6 GtCO2e, or 3.3 percent) (1.4 GtCO2e, or 2.8 percent ).
The largest source of emissions in the energy sector is heat and electricity generation (15.6 GtCO2e in 2018, or 31.9 percent of total emissions), followed by transportation (6.9 GtCO2e in 2018, or 14.2 percent of total emissions), and manufacturing and construction (6.9 GtCO2e in 2018, or 14.2 percent of total emissions) (6.2 GtCO2e, or 12.6 percent of total emissions).
Why does China produce the most amount of greenhouse gases?
Construction-related activities are one of the most significant contributors of CO2. These operations have been accelerated by China’s tremendous urbanization expansion. Cement and steel manufacture, which have supported China’s infrastructure development, both release significant amounts of CO2 during the refining process.
Which country is the least responsible for global warming?
What they discovered is that the lowest ten countries are all from Sub-Saharan Africa, with Somalia being named the country least likely to survive climate change. Due to weak infrastructure, insecure governance, a lack of healthcare, and food and water scarcity, these countries did badly.
Which country emits the most CO2 per capita in 2020?
CO2 emissions per person worldwide in 2020, by nation Qatar has the greatest carbon dioxide emissions per capita in the world, with 37 metric tons per person.
Since 1850, which country has emitted the greatest total greenhouse gases?
The United States, which ranks top in the rankings, has emitted more than 509 GtCO2 since 1850 and is responsible for the highest proportion of historical emissions, accounting for around 20% of the world total, according to Carbon Brief data.
