What You'll Learn
China's emissions
China, officially known as the People's Republic of China, is the world's largest annual emitter of greenhouse gases. In 2020, China emitted 12.3 billion tonnes of carbon dioxide equivalent (GtCO2e), accounting for 27% of global greenhouse gas emissions. China's emissions stem primarily from coal burning, with coal power, coal mining, and blast furnaces for iron and steel production being significant contributors. According to the Carbon Majors Database, Chinese state coal production alone accounts for 14% of historical global emissions. China is home to half of the world's coal power plants and is the fifth-largest oil producer and second-largest consumer.
China's per capita emissions correspond to over 10.1 tonnes of carbon dioxide equivalent emitted per person each year, exceeding the world average. However, its cumulative and per capita emissions are still about half of those of the United States. China's economy has been slowing down recently, which could have implications for global energy markets and carbon dioxide emissions. Despite this, China's carbon dioxide emissions reached a record high of nearly 12 billion metric tons between April 2020 and March 2021.
China has committed to reducing its emissions and has set targets to peak emissions by 2030 and achieve carbon neutrality by 2060. The country has been participating in international climate negotiations under the United Nations Framework Convention on Climate Change (UNFCCC) and has made progress in renewable energy and low-carbon technologies. China is estimated to overachieve its renewable energy capacity and emission reduction goals early, but long-term plans are still needed to combat global climate change effectively.
While China's emissions are a significant concern, it is important to recognize that almost all countries contribute to global pollution. The situation underscores the urgent need to reduce greenhouse gas emissions and mitigate the impacts of climate change.

India's per capita emissions
However, it's important to consider that per capita emissions are influenced by various factors, such as population size and the structure of the economy and energy system. For example, countries with a higher reliance on carbon-intensive transportation, energy-intensive industries, or fossil fuels for power generation will have higher per capita emissions. Additionally, the production and consumption patterns of a country can also impact its per capita emissions.
To address India's per capita emissions and overall pollution problem, the country needs to decouple its economic growth from CO2 emissions. This involves reducing emissions while still achieving increasing prosperity. India has taken initiatives to combat climate change, but more comprehensive and effective measures are necessary to mitigate the environmental impact.

US climate policies
While it is challenging to definitively state which country has the biggest pollution problem, this answer will focus on US climate policies, as requested.
The United States has been taking steps to address climate change and reduce its environmental impact. Climate change policy is developed at both the state and federal levels of the US government, with the Environmental Protection Agency (EPA) defining climate change as:
> "any significant change in the measures of climate lasting for an extended period of time. Climate change includes major changes in temperature, precipitation, or wind patterns, as well as other effects, that occur over several decades or longer."
The US has implemented various policies and initiatives to tackle climate change, with the current administration committed to a whole-of-society approach. Here are some key examples of US climate policies:
The Inflation Reduction Act (IRA): The IRA is a significant piece of legislation that has mobilised investments in clean energy solutions and climate change mitigation. It has also led to revised regulations in the power and transport sectors, strengthening the government's climate policy package. The Act has already shown promising results, with expectations for GHG emissions reductions by 2030 relative to 2005 levels increasing from 17%-30% to 29%-42%.
Paris Agreement and International Cooperation: The US has rejoined the Paris Agreement, demonstrating its commitment to global efforts to combat climate change. The country has also strengthened its international cooperation by convening Leaders' Summits on climate, ratifying the Kigali Amendment to the Montreal Protocol, and increasing pledges to multilateral climate funds.
Methane Emissions Reduction: The US has taken swift steps to cut methane emissions, including strengthened EPA regulations on oil and gas methane mitigation and the implementation of the Methane Emissions Reduction Program. The focus on methane emissions is a cost-effective strategy to reduce temperatures in the short term.
Clean Energy Investments: The Biden administration has overseen significant investments in clean energy manufacturing, with over $240 billion directed towards this sector. This has put the US on track to substantially increase wind and solar generation capacity by 2030.
Vehicle Standards and Electric Vehicles: The US has implemented the strongest passenger vehicle standards in its history, aiming to increase average fuel economy to 49 miles per gallon by 2026. Additionally, the country has set ambitious targets for electric vehicle sales, aiming for a 50% market share by 2030 and 100% carbon pollution-free electricity by 2035.
Bipartisan Infrastructure Law: This law provides over $26 billion to support nature-based solutions, including ecosystem restoration, wildfire risk reduction, and the uptake of climate-smart agricultural practices.
State and Local Action: While federal policies are crucial, much of the climate action in the US occurs at the state and local levels. Regional organisations, states, and cities are implementing policies to increase renewable energy generation, sell agricultural carbon sequestration credits, and encourage efficient energy use.
White House Office of Energy and Climate Change Policy: Established under the Obama administration, this office was created to focus on addressing global climate change and the development of clean energy.
Despite these efforts, the US still faces challenges in meeting its climate goals, particularly in reducing emissions and aligning with a 1.5°C trajectory. Additional policies and more drastic emissions reduction measures may be needed to achieve these targets.
Furthermore, the US has been criticised for its lack of regulations regarding emissions from animal production and its failure to encourage dietary changes, which could have significant mitigation impacts due to the country's high meat and dairy consumption.
Overall, while the US has made progress in addressing climate change, there is still much work to be done to ensure a sustainable future.

EU's carbon leakage
While it is challenging to pinpoint a single country as the most polluting, several countries stand out as the most polluting on the planet. China, for instance, has the world's biggest industrial and commercial power, and while it has led important initiatives to combat climate change, many have proven insufficient. Fourteen out of the world's 15 most contaminated cities are in India, according to the World Health Organization.
Now, concerning the EU's carbon leakage, this refers to the potential issue of businesses transferring their production to countries with less stringent emission constraints due to the costs associated with climate policies. In other words, carbon leakage happens when industries relocate to avoid stringent climate policies, resulting in increased emissions in regions with weaker environmental regulations. This phenomenon is of particular concern for energy-intensive industries, such as steel and cement manufacturing, which face intense global competition. The risk of carbon leakage is higher in these sectors due to their exposure to international trade and the potential for relocating operations to evade regulations.
The EU Emissions Trading System (EU ETS), the largest emissions trading system globally, has been crucial in Europe's fight against climate change. However, carbon leakage has been a central concern within this framework. The EU introduced the Carbon Border Adjustment Mechanism (CBAM) in 2023 to address carbon leakage by imposing carbon pricing on imports. The CBAM aims to reduce carbon leakage by preventing unfair competition and encouraging global alignment with climate policies. It is estimated to decrease carbon leakage by 19%.
To further mitigate the risk of carbon leakage, the EU provides special treatment to industrial installations at significant risk. These industries receive a higher share of free allowances compared to others, ensuring their competitiveness. However, the number of sectors on the carbon leakage list has decreased due to revised EU ETS Directive provisions, resulting in a more focused approach. This ensures that sectors most at risk receive an adequate number of free allowances.
In conclusion, while the EU has made significant strides in combating climate change through the EU ETS, carbon leakage remains a critical issue requiring ongoing attention and policy interventions, such as the implementation of CBAM and the allocation of free allowances.

Global pollution solutions
While it is difficult to pinpoint which country is the most polluting, India, with its enormous export market, is a serious contender for the title. Fourteen out of the world's 15 most contaminated cities are in India, according to the World Health Organization. China, the world's biggest industrial and commercial power, is also a major polluter, with Beijing experiencing constant red alerts for environmental pollution in recent years.
However, almost all the world's countries are responsible for the high level of global pollution, and it is a problem that requires a global response. Here are some solutions that can help address the issue of pollution worldwide:
Political Commitment and International Cooperation: In 2017, ministers of environment from around the world gathered at the United Nations Environment Assembly (UNEA) and expressed their commitment to working towards a pollution-free planet. Governments adopted resolutions targeting specific aspects of pollution, including air quality, water pollution, soil pollution, marine litter, microplastics, and chemicals and waste. International cooperation and political will are crucial in addressing global pollution.
Green Technologies and Ecosystem-based Solutions: Encouraging the adoption of green technologies and ecosystem-based solutions can foster innovation and sustainability. Sustainable transport, waste management, buildings, and industry practices can significantly reduce pollution levels and lead to cleaner air in cities.
Clean Energy and Low-Carbon Policies: Transitioning from polluting fuels like kerosene and coal to cleaner alternatives such as solar, biofuels, biogas, and liquefied petroleum gas (LPG) can reduce air pollution and mitigate climate change. India's successful LPG reform, PaHaL, is an example of how energy subsidy reform can improve access to clean cooking fuel and reduce household air pollution.
Waste Management and Pollution Governance: Proper waste management and disposal of chemicals and waste are essential. The World Bank supports initiatives to address marine litter, improve waste management, and reduce the production of single-use plastics. The Montenegro Industrial Waste Management and Cleanup Project is another example of effective waste management, ensuring hazardous waste disposal complies with relevant legislation.
Addressing Root Causes and Circular Economy: Traditional approaches to pollution have focused on clean-up efforts, but it is crucial to address the root causes. The "take, make, waste" linear economy has led to excessive disposal and environmental degradation. Promoting a circular economy, where production systems are regenerative and restorative, can help tackle pollution at its source.
Innovation and Data-driven Solutions: Some companies are innovating to address pollution. For example, IKEA created curtains that absorb air pollution, and Nexleaf Analytics uses data-driven solutions to bring clean cooking technologies to low- and middle-income countries.
By implementing these solutions and continuing to prioritize global cooperation, it is possible to make significant strides in combating pollution and creating a cleaner, healthier planet for all.
