A Global Breakdown of Greenhouse Gas Emissions by Sector

In a few decades, greenhouse gases (GHGs)—chiefly in the form of CO₂ emissions—have risen at unprecedented rates as a result of global growth and resource consumption.

To uncover the major sectors where these emissions originate, this graphic from Our World in Data pulls the latest data from 2016 courtesy of Climate Watch and the World Resources Institute, when total emissions reached 49.4 billion tonnes of CO₂ equivalents (CO₂e).

Sources of GHG Emissions

Global GHG emissions can be roughly traced back to four broad categories: energy, agriculture, industry, and waste. Overwhelmingly, almost three-quarters of GHG emissions come from our energy consumption.

Sector	Global GHG Emissions Share
Energy Use	73.2%
Agriculture, Forestry & Land Use	18.4%
Industrial processes	5.2%
Waste	3.2%

Within each category, there are even more granular breakdowns to consider. We’ll take a closer look at the top two, which collectively account for over 91% of global GHG emissions.

Energy Use

Within this broad category, we can further break things down into sub-categories like transport, buildings, and industry-related energy consumption, to name a few.

Sub-sector	GHG Emissions Share	Further breakdown
Transport	16.2%	• Road 11.9% • Aviation 1.9% • Rail 0.4% • Pipeline 0.3% • Ship 1.7%
Buildings	17.5%	• Residential 10.9% • Commercial 6.6%
Industry energy	24.2%	• Iron & Steel 7.2% • Non-ferrous metals 0.7% • Machinery 0.5% • Food and tobacco 1.0% • Paper, pulp & printing 0.6% • Chemical & petrochemical (energy) 3.6% • Other industry 10.6%
Agriculture & Fishing energy	1.7%	-
Unallocated fuel combustion	7.8%	-
Fugitive emissions from energy production	5.8%	• Coal 1.9% • Oil & Natural Gas 3.9%
Total	73.2%

Billions of people rely on petrol and diesel-powered vehicles to get around. As a result, they contribute to almost 12% of global emissions.

But this challenge is also an opportunity: the consumer adoption of electric vehicles (EVs) could significantly help shift the world away from fossil fuel use, both for passenger travel and for freight—although there are still speedbumps to overcome.

Meanwhile, buildings contribute 17.5% of energy-related emissions overall—which makes sense when you realize the stunning fact that cities use 60-80% of the world’s annual energy needs. With megacities (home to 10+ million people) ballooning every day to house the growing urban population, these shares may rise even further.

Agriculture, Forestry & Land Use

The second biggest category of emissions is the sector that we rely on daily for the food we eat.

Perhaps unsurprisingly, methane from cows and other livestock contribute the most to emissions, at 5.8% total. These foods also have some of the highest carbon footprints, from farm to table.

Sub-sector	GHG Emissions Share
Livestock & Manure	5.8%
Agricultural Soils	4.1%
Crop Burning	3.5%
Forest Land	2.2%
Cropland	1.4%
Rice Cultivation	1.3%
Grassland	0.1%
Total	18.4%

Another important consideration is just how much land our overall farming requirements take up. When significant areas of forest are cleared for grazing and cropland, there’s a clear link between our land use and rising global emissions.

Although many of these energy systems are still status quo, the global energy mix is ripe for change. As the data shows, the potential points of disruption have become increasingly clear as the world moves towards a green energy revolution.

The Scale of Global Fossil Fuel Production

Fossil fuels have been our predominant source of energy for over a century, and the world still extracts and consumes a colossal amount of coal, oil, and gas every year.

This infographic visualizes the volume of global fossil fuel production in 2021 using data from BP’s Statistical Review of World Energy.

The Facts on Fossil Fuels

In 2021, the world produced around 8 billion tonnes of coal, 4 billion tonnes of oil, and over 4 trillion cubic meters of natural gas.

Most of the coal is used to generate electricity for our homes and offices and has a key role in steel production. Similarly, natural gas is a large source of electricity and heat for industries and buildings. Oil is primarily used by the transportation sector, in addition to petrochemical manufacturing, heating, and other end uses.

Here’s a full breakdown of coal, oil, and gas production by country in 2021.

Coal Production

If all the coal produced in 2021 were arranged in a cube, it would measure 2,141 meters (2.1km) on each side—more than 2.5 times the height of the world’s tallest building.

China produced 50% or more than four billion tonnes of the world’s coal in 2021. It’s also the largest consumer of coal, accounting for 54% of coal consumption in 2021.

Rank	Country	2021 Coal Production (million tonnes)	% of Total
#1	🇨🇳 China	4,126.0	50%
#2	🇮🇳 India	811.3	10%
#3	🇮🇩 Indonesia	614.0	8%
#4	🇺🇸 U.S.	524.4	6%
#5	🇦🇺 Australia	478.6	6%
#6	🇷🇺 Russia	433.7	5%
#7	🇿🇦 South Africa	234.5	3%
#8	🇩🇪 Germany	126.0	2%
#9	🇰🇿 Kazakhstan	115.7	1%
#10	🇵🇱 Poland	107.6	1%
	🌍 Other	600.9	7%
	Total	8,172.6	100%

India is both the second largest producer and consumer of coal. Meanwhile, Indonesia is the world’s largest coal exporter, followed by Australia.

In the West, U.S. coal production was down 47% as compared to 2011 levels, and the descent is likely to continue with the clean energy transition.

Oil Production

In 2021, the United States, Russia, and Saudi Arabia were the three largest crude oil producers, respectively.

Rank	Country	2021 Oil Production (million tonnes)	% of Total
#1	🇺🇸 U.S.	711.1	17%
#2	🇷🇺 Russia	536.4	13%
#3	🇸🇦 Saudi Arabia	515.0	12%
#4	🇨🇦 Canada	267.1	6%
#5	🇮🇶 Iraq	200.8	5%
#6	🇨🇳 China	198.9	5%
#7	🇮🇷 Iran	167.7	4%
#8	🇦🇪 UAE	164.4	4%
#9	🇧🇷 Brazil	156.8	4%
#10	🇰🇼 Kuwait	131.1	3%
	🌍 Other	1172.0	28%
	Total	4221.4	100%

OPEC countries, including Saudi Arabia, made up the largest share of production at 35% or 1.5 billion tonnes of oil.

U.S. oil production has seen significant growth since 2010. In 2021, the U.S. extracted 711 million tonnes of oil, more than double the 333 million tonnes produced in 2010.

Natural Gas Production

The world produced 4,036 billion cubic meters of natural gas in 2021. The above graphic converts that into an equivalent of seven billion cubic meters of liquefied natural gas (LNG) to visualize it on the same scale as oil and gas.

Here are the top 10 producers of natural gas in 2021:

Rank	Country	2021 Natural Gas Production (billion m³)	% of Total
#1	🇺🇸 U.S.	934.2	23%
#2	🇷🇺 Russia	701.7	17%
#3	🇮🇷 Iran	256.7	6%
#4	🇨🇳 China	209.2	5%
#5	🇶🇦 Qatar	177.0	4%
#6	🇨🇦 Canada	172.3	4%
#7	🇦🇺 Australia	147.2	4%
#8	🇸🇦 Saudi Arabia	117.3	3%
#9	🇳🇴 Norway	114.3	3%
#10	🇩🇿 Algeria	100.8	2%
	🌍 Other	1106.3	27%
	Total	4,036.9	100%

The U.S. was the largest producer, with Texas and Pennsylvania accounting for 47% of its gas production. The U.S. electric power and industrial sectors account for around one-third of domestic natural gas consumption.

Russia, the next-largest producer, was the biggest exporter of gas in 2021. It exported an estimated 210 billion cubic meters of natural gas via pipelines to Europe and China. Around 80% of Russian natural gas comes from operations in the Arctic region.
