While China, the United States, and India are the three countries with the highest carbon dioxide (CO2) emissions, their carbon footprint per capita tells a different story. In 2023, China's CO2 emissions per capita were almost two-thirds those of the United States, making the average American responsible for nearly twice as much climate pollution as the average person in China. India, despite being one of the world's biggest climate polluters, has per capita emissions significantly below the global average.

What You'll Learn
Per capita emissions in China vs. the US
China and the United States are the world's two biggest greenhouse gas emitters. China's emissions are more than double those of the US; however, the US has emitted more historically than any other country. China's per capita emissions are rapidly catching up with those of wealthier nations. In 2019, China's per capita emissions reached 10.1 tons, while the US reached 17.6 tons, according to the Rhodium Group. The average American is responsible for nearly twice as much climate pollution as the average person in China.
In 2020, fossil fuels made up 87% of China's domestic energy mix, with 60% from coal, 20% from oil, and 8% from natural gas. China's large population of 1.4 billion people means that it will logically emit more than smaller nations overall. However, when looking at per capita emissions, the average Chinese person emits less than the average American. This disparity is partly due to differences in lifestyle and income levels between the two countries. Americans typically earn higher incomes, own more fuel-inefficient vehicles, and travel by air more frequently than their Chinese counterparts.
The United States has taken steps to reduce its per capita carbon dioxide emissions, with notable decreases beginning in the 1970s. However, it is important to note that US emissions are not entirely independent of other countries' emissions. A significant portion of China's rising emissions is related to manufacturing, with many of the resulting products being purchased by American consumers. The United States imported $450.4 billion worth of goods from China in 2020, according to the Office of the United States Trade Representative. This interdependence between countries underscores the need for global cooperation in addressing climate change.
Both China and the United States are crucial players in the global effort to combat climate change. As the two largest emitters, their actions and commitments to reducing emissions will significantly impact the rest of the world. While China's overall emissions surpass those of the US, examining per capita emissions provides a more nuanced perspective that considers population size. As countries work towards meeting the goals of the Paris Climate Agreement and limiting global temperature rise, the contributions and responsibilities of major emitters like China and the US will remain in the spotlight.

India's rising emissions
India's fossil CO₂ emissions have nearly tripled, reaching 2.7 GtCO₂ in 2022, the highest in its history. The primary factor contributing to this rise is the increasing use of coal-fired electricity generation, which currently accounts for three-quarters of India's energy supply. The power sector is the largest emitter, responsible for 32% of India's total GHG emissions, followed by the agriculture and manufacturing sectors.
India's energy transition has seen significant progress, with the country emerging as a global leader in renewable energy, particularly solar power. However, its ambitious climate goals are undermined by its continued reliance on coal. India plans to increase coal output to meet the growing energy demands driven by industrialization, urbanization, and increased spending power. This challenge of balancing economic growth with decarbonization is further exacerbated by the need to address the rising demand for cooling amid heatwaves.
While India has made substantial progress in installing renewable energy capacity, its fossil fuel demand, particularly coal, remains unchanged. Coal production and imports reached record highs in the first half of 2024 to meet seasonal electricity demand during the summer heat. India's climate targets and policies have been rated as "Highly Insufficient," indicating a misalignment with the Paris Agreement's 1.5°C temperature limit.
To address this issue, India could expedite policy and technical support for grid integration of renewable energy and storage capacity. Additionally, the country should avoid locking into a dependency on fossil fuel imports and plan for the early retirement of existing thermal capacity. India has set commitments to tackle climate change, including reducing the carbon intensity of its economy by at least 45% by 2030 compared to 2005 levels and achieving net-zero carbon emissions by 2070. However, stronger targets and accelerated climate policy implementation are needed to drive significant emission reductions.

Consumption-based emissions
When considering consumption-based emissions per capita, which represents the average emissions per person in a country, the picture can change significantly. For instance, while China is the largest climate polluter in terms of total emissions, the average American is responsible for nearly twice as much climate pollution per person. Similarly, India, despite being one of the world's biggest polluters, has per capita emissions significantly below the global average due to its large population.

Fossil fuels and CO2 emissions
Fossil fuels are a significant contributor to global CO2 emissions, with coal, oil, and gas combustion being the primary sources. In 2022, global CO2 emissions from fossil fuels reached a record high, with China, the United States, India, and the European Union being the top emitters. China saw the highest growth in emissions, while the US and India also had notable increases. Per capita emissions, however, paint a different picture, with the average American responsible for nearly twice as much climate pollution as the average person in China, and India's per capita emissions being significantly below the global average.
China, the United States, and India are the three most industrialised countries in the world, and it is no surprise that they are also the top three carbon dioxide emitters. However, when it comes to per capita emissions, which take into account the population of the country, the ranking changes. While China is the largest overall emitter, the United States has higher per capita emissions, and India's per capita emissions are even lower in comparison. This is partly due to India's much lower per capita emissions, despite being one of the most populous countries in the world.
Fossil fuel emissions are primarily driven by the combustion of coal, oil, and gas. Coal is the largest contributor to global CO2 emissions, responsible for approximately 40% of emissions in 2022. Oil follows closely behind, contributing 32% of fossil CO2 emissions. Gas and cement production are also significant, but to a lesser extent, contributing 21% and 4% respectively. These percentages can vary depending on the amount of each fossil fuel consumed globally and the CO2 intensities of each fuel.
In 2022, global CO2 emissions from fossil fuels saw a 37.5% change, with emissions in the United States, European Union, and the rest of the world remaining below pre-pandemic levels. However, emissions in China were 5.8% higher than in 2019, and India's emissions were 9.3% above 2019 levels. This increase in global emissions is concerning, especially considering the goals set by the Paris Climate Agreement to reduce CO2 emissions and limit global warming.
While India is the third-largest emitter in terms of total emissions, its per capita emissions are much lower, and the country is making significant efforts to reduce its greenhouse gas emissions. India is investing in renewable energy projects, although it still relies on coal. The transition to renewable energy sources is crucial in reducing global CO2 emissions and mitigating the impacts of climate change.

The Paris Climate Agreement
The Paris Agreement was reached in Paris in December 2015 and was soon ratified by almost all nations. The agreement came into force on November 4, 2016, and has been signed by 194 states and the European Union as of March 2021. The United States is the only nation to have withdrawn from the agreement, with former President Donald Trump pulling out of the deal in 2017 and again in 2025.
The main goal of the Paris Agreement is to limit global warming to well below 2 degrees Celsius, with an ambitious target of 1.5 degrees. This target was agreed upon because evidence suggests that the impacts of global warming will become much more extreme as the temperature approaches 2 degrees. To achieve this goal, the agreement focuses on lowering greenhouse gas emissions through a system of pledge and review. Each signatory commits to declaring a plan of climate action, known as a "nationally determined contribution" or NDC, which includes a pledge to reduce emissions by a certain amount before a target date, usually 2030.
To support the implementation of the agreement, richer nations have reaffirmed their obligation to provide financial and technological aid to developing countries. This is crucial as developing countries produce more than half of today's global greenhouse gas emissions, and their emissions are growing faster than those of wealthy countries. The Paris Agreement builds on previous international efforts to address climate change, such as the 2009 Copenhagen Accord, and provides a strong framework for all nations to collectively tackle the climate crisis.
