What You'll Learn
China: the world's largest CO2 emitter
China is the world's largest emitter of carbon dioxide (CO2). In 2023, China emitted more than 14 billion tons of CO2, accounting for the largest share of global emissions. China's high emissions are primarily driven by its extensive use of coal, which has been used to grow its economy. However, it is important to note that when considering CO2 emissions per capita, the average American is responsible for nearly twice as much climate pollution as the average person in China.
China's emissions have significant environmental implications, with Beijing experiencing constant red alerts for environmental pollution in recent years. The effects of China's emissions contribute to global warming and climate change, with the International Energy Agency (IEA) forecasting an increase in emissions of 130% by 2050 if no mitigating actions are taken.
While China's emissions have started to plateau, they are projected to peak by 2025. The country has recognized the need to reduce emissions and has led important initiatives to combat climate change. However, many of these initiatives have been shown to be insufficient, and China still faces the challenge of balancing its economic growth with environmental sustainability.
China's role as the world's largest emitter highlights the urgency of addressing the climate crisis. Global efforts, such as the agreements reached at COP28 in Dubai in 2023, aim to standardize emissions control and accelerate the transition to a low-carbon economy. China's cooperation and commitment to reducing emissions are crucial in mitigating the impacts of climate change on a global scale.
In summary, China's position as the world's largest CO2 emitter underscores the need for collective action and effective policies to combat climate change. While China has taken steps towards addressing its emissions, continued efforts and international collaboration are necessary to achieve meaningful progress in reducing the impacts of climate change.

India: rising emissions, reliant on coal
India is one of the world's biggest climate polluters, with its emissions steeply on the rise. In 2023, India had the largest increase in emissions relative to the previous year, with a 6.1% increase. India's per capita emissions, however, are significantly below the global average. This is because India is the world's second most populous country, with over 1.4 billion people.
India's growing emissions are driven by its reliance on coal. While the country is investing in major renewable energy projects, it still heavily depends on coal. India's development trajectory is also a factor in its rising emissions. As India continues to develop, its emissions are projected to increase.
India's burning of fossil fuels has grown significantly, and as a result, the country ranks third in global air pollution rankings. Fourteen of the world's 15 most contaminated cities are in India, according to the World Health Organization. Despite having a law protecting air quality since 1981, India's pollution levels are not limited to big cities, with many rural areas also experiencing the consequences.
India's situation reflects the broader challenge of balancing economic development and environmental sustainability. While there is a growing awareness of the need to reduce emissions, the country faces the dual tasks of addressing current pollution levels and managing future emissions growth. India's large population and emerging economy contribute to its unique context in the global climate change landscape.

US: responsible for historical emissions
While China is the biggest emitter of carbon dioxide overall, the United States is responsible for the highest per capita emissions. That is, the average American is responsible for nearly twice as much climate pollution as the average person in China. This is due in part to the US's historical reliance on fossil fuels and its industrial revolution period.
The US and the EU top the chart of historical emissions, which are calculated by measuring the total emissions divided by population. Developed countries have emitted so much over the last 200 years that, according to Climate Action Tracker analyst Höhne, "they are now in debt."
The US has taken legislative action to address its contribution to climate change, such as the Inflation Act, which takes a multifaceted approach to combat climate change. The act includes provisions related to clean energy investments, tax credits for renewable projects, and initiatives to accelerate the transition to a low-carbon economy. However, despite agreements such as the Kyoto Protocol, carbon dioxide emissions continue to rise, and the US still has a long way to go in reducing its emissions.
The US, along with other developed nations, has a responsibility to rapidly scale up its climate ambitions and take action to reduce its carbon emissions and offset its carbon footprint. This can be done through supporting environmental projects, investing in clean energy, and promoting sustainable practices.

EU: historical emissions, carbon leakage
China is the world's biggest polluter in terms of total emissions. However, when looking at per capita emissions, the average American is responsible for nearly twice as much climate pollution as the average person in China.
EU: Historical Emissions and Carbon Leakage
The EU is one of the world's top polluters, in part due to its historical emissions. The EU Emissions Trading System (EU ETS) has been in place since 2005 to reduce emissions in participating countries and industries. While the EU ETS has been successful in reducing emissions, there are concerns about carbon leakage.
Carbon leakage refers to the potential transfer of production to countries with less stringent emission constraints, which could lead to an increase in total emissions. To mitigate this risk, the EU provides special treatment to industrial installations at significant risk of carbon leakage, including a higher share of free allowances. The eligibility criteria for free allowances have become more stringent in phase 4 (2021-2030), focusing on sectors at the highest risk of relocating outside the EU.
There is some debate about the extent of carbon leakage caused by the EU ETS. While some studies indicate that carbon leakage has occurred, others found no evidence of it. The additional cost of European emissions policies is relatively small, and firms relocating production incur fixed relocation costs and opportunity costs in the home market. Furthermore, emissions policies often provide subsidies to counter the leakage risk.

Russia and Brazil: increased emissions in 2023
While China is the biggest polluter in terms of overall emissions, the average American citizen produces nearly twice as much climate pollution as the average person in China. The US and the EU top the Climate Action Tracker's chart, which analyses countries' "fair share" of emissions reductions, due to their high levels of historical emissions and ability to pay for climate action.
Russia and Brazil have both experienced increased emissions in 2023. In Russia, carbon dioxide emissions from energy combustion in 2023 amounted to approximately 1.61 billion metric tons of CO2, marking an increase from the previous year. Russia accounted for 5% of worldwide greenhouse gas emissions in 2023, ranking behind China, the US, and India. The energy sector was the largest emitter, followed by industrial production, agriculture, and waste management. Brazil, meanwhile, is ranked 28th in the Climate Change Performance Index (CCPI) and is considered a medium climate performer. While Brazil has shown positive developments in its climate policy, including strong measures against deforestation and substantial reductions in Amazon deforestation rates in 2023, leading to lower emissions, these reductions are not yet reflected in its ranking due to the unavailability of 2023 data on land use, land-use change, and forestry (LULUCF). Brazil's reliance on fossil fuels and hydropower also contradicts its climate policy goals.
Russia's emissions increase in 2023 can be attributed to various factors, including the energy sector, industrial production, agriculture, and waste management. The country's energy sector, in particular, is the largest emitter, contributing significantly to the overall increase in carbon dioxide emissions. Russia's territorial carbon dioxide emissions per capita have also been on the rise, growing by 13% between 2000 and 2022.
Brazil has also experienced increased emissions in recent years, despite its efforts to improve climate policies. The country's medium rating for Renewable Energy, Energy Use, and Climate Policy, and low rating for GHG Emissions, highlight areas for improvement. While Brazil has made progress in reducing deforestation and increasing renewables, it needs to address its reliance on fossil fuels and enhance its energy infrastructure. Brazil's support for new oil and gas ventures, as well as its plans for coal subsidies until 2040, contradict its climate policy goals.
Both Russia and Brazil face the challenge of balancing their economic activities with the need to reduce emissions and adhere to their climate policies. While Brazil has shown promising developments in reducing deforestation and improving climate policies under President Luiz Inácio Lula da Silva, who took office in January 2023, Russia's emissions continue to rise, with the energy sector playing a significant role. As countries strive towards net-zero emissions by 2050, Russia and Brazil must address their respective sources of increased emissions and implement effective strategies to curb their environmental impact.
