In 2023, China was the biggest carbon polluter in the world by far, having released 11.9 billion metric tons of carbon dioxide (GtCO₂). Although the U.S. was the second-biggest emitter, with 4.9 GtCO₂ in 2023, its CO₂ emissions have declined by 13 percent since 2010. By comparison, China’s CO₂ emissions have increased by more than 38 percent in the same period. Cumulative emissions Although China is currently the world's largest carbon polluter, the U.S. has released far more historical carbon dioxide emissions, at more than 400 GtCO₂ since 1750. The wide gap between the two countries is because China's emissions have mostly been produced in the past two decades. Combined, the U.S. and China account for roughly 40 percent of cumulative CO₂ emissions since the Industrial Revolution began. Sources of emissions One of the largest sources of global CO₂ emissions is the power sector, with electricity produced by coal-fired power plants a significant contributor. In China, emissions from coal-fired electricity generation have soared since the turn of the century, and reached 5.2 GtCO₂ in 2023.

Global carbon dioxide emissions from fossil fuels and industry totaled 37.01 billion metric tons (GtCO₂) in 2023. Emissions are projected to have risen 1.08 percent in 2024 to reach a record high of 37.41 GtCO₂. Since 1990, global CO₂ emissions have increased by more than 60 percent. Who are the biggest emitters? The biggest contributor to global GHG emissions is China, followed by the United States. China wasn't always the world's biggest emitter, but rapid economic growth and industrialization in recent decades have seen emissions there soar. Since 1990, CO₂ emissions in China have increased by almost 450 percent. By comparison, U.S. CO₂ emissions have fallen by 6.1 percent. Nevertheless, the North American country remains the biggest carbon polluter in history. Global events cause emissions to drop The outbreak of COVID-19 caused global CO₂ emissions to plummet some 5.5 percent in 2020 as a result of lockdowns and other restrictions. However, this wasn't the only time in recent history when a major global event caused emissions reductions. For example, the global recession resulted in CO₂ levels to fall by almost two percent in 2009, while the recession in the early 1980s also had a notable impact on emissions. On a percentage basis, the largest annual reduction was at the end of the Second World War in 1945, when emissions decreased by 17 percent.

Qatar had the highest per capita carbon dioxide emissions worldwide in 2023, at 42.6 metric tons per person. Per capita emissions in Qatar have remained relatively stable in recent years, but have fallen notably since the mid-2000s.In 1985, the tiny Dutch Caribbean island of Curaçao had the highest CO₂ emissions per capita in the world, at 90 metric tons, but by 2020, this figure had fallen to just 10 metric tons per person. Greenhouse gas emissions worldwide Several of the Middle East’s largest oil producing countries, including Qatar, the United Arab Emirates, and Saudi Arabia, are among the world’s largest per capita CO₂ emitters. Per capita emissions in Saudi Arabia have experienced a growth of roughly 75 percent since 1990. Canada is another major oil producing country with high CO₂ emissions per capita. Rising emissions Global greenhouse gas emissions have been on the rise since the industrial revolution began approximately 200 years ago. However, over the past 50 years CO₂ emissions have skyrocketed, and are projected to have reached a new record high in 2024.

The average for 2023 based on 189 countries was 198 Mt CO2 eq. The highest value was in China: 13260 Mt CO2 eq and the lowest value was in Antigua and Barbuda: 0 Mt CO2 eq. The indicator is available from 1970 to 2023. Below is a chart for all countries where data are available.

This dataset is about countries per year in China. It has 64 rows. It features 3 columns: country, and carbon dioxide emissions (CO2).

China's carbon dioxide emissions have risen more than fivefold since 1990, with the country accounting for around 34 percent of total global CO₂ emissions in 2023. In comparison, CO₂ emissions in the United Kingdom were almost 50 percent lower than in 1990. Why have emissions in the UK dropped? The UK achieved the biggest emissions reductions between 1990 and 2023 among the world's 20 biggest CO₂ emitters. Much of the UK’s emissions cuts are attributable to the country’s phase-out of coal-fired power and the shift toward natural gas and renewable energy sources. CO₂ emissions growth in developing countries While emissions in developed countries, including the UK, U.S. Japan, and Germany, have experienced overall reductions since 1990, those in developing regions have soared. For example, rapid economic development has seen annual CO₂ emissions in India increase almost fivefold since 1990 to around three billion metric tons, while those in Vietnam have grown almost 2,000 percent.

The average for 2023 based on 7 countries was 8.09 metric tons of carbon dioxide equivalent per capita. The highest value was in Canada: 14.34 metric tons of carbon dioxide equivalent per capita and the lowest value was in France: 4.14 metric tons of carbon dioxide equivalent per capita. The indicator is available from 1970 to 2023. Below is a chart for all countries where data are available.

This dataset is about countries per year in Oceania. It has 896 rows. It features 3 columns: country, and carbon dioxide emissions (CO2).

Over the past two decades, many developing countries have experienced significant growth in per capita emissions. This is particularly the case in Asia. Fueled by rapid industrialization, per capita emissions in Vietnam have increased by almost 400 percent since 2000. Per capita emissions in China, India, and Indonesia have also increased substantially during this period. In comparison, per capita emissions in developed countries such as the United Kingdom have halved since 2000. Per capita emissions The growth in per capita emissions in China has coincided with the country becoming the world’s biggest emitter. However, despite the vast amounts of carbon dioxide China releases every year, its per capita emissions are far lower than in many other countries, at just eight metric tons per person. In comparison, the average American produces nearly 15 metric tons of carbon dioxide a year. This is three times higher than the average per capita emissions worldwide. Emissions in oil producing countries Per capita emissions are noticeably higher in oil producing countries. In the Middle East region, Qatar and Kuwait average more than 25 metric tons of CO₂ per inhabitant. People in more populous oil producing countries, such as Canada and Australia, average roughly 15 metric tons of carbon dioxide a year.
