Pollution Reduction Efforts: Global Climate Change Champions

Climate change is an urgent global issue, and while almost all countries are responsible for high levels of pollution, some are taking steps to reduce their carbon emissions and offset their carbon footprint. China, the United States, India, and the European Union are among the top polluters and have a significant impact on the rest of the world with their responses to the climate crisis. While China leads in emissions, primarily due to its extensive use of coal, the average American is responsible for nearly twice as much climate pollution per capita. The US has historically been the largest polluter over time, and developed countries bear a greater responsibility for climate change, having built their wealth on fossil fuels. However, China has also experienced a rapid, coal-fired economic boom, and both the US and China have been criticised for financing coal-fired power plants outside their borders. Despite this, some countries are taking steps to address the issue, with the US passing the Inflation Reduction Act, the largest climate investment in its history, and the EU introducing the Carbon Border Adjustment Mechanism to address carbon leakage and encourage global partners to adopt more sustainable practices.

China's extensive use of coal

China's coal usage accounts for nearly 30% of global emissions, with the average American responsible for almost double the climate pollution per capita. China's coal-fired power plants are a major source of greenhouse gas emissions, and the country's installed coal-based power generation capacity was about half of its total installed capacity in 2021. Despite recent efforts to transition to renewable energy sources, China's coal consumption reached new heights in 2022, with carbon dioxide emissions from coal-fired electricity production estimated at 4.5 billion tons.

China's coal production and consumption have far-reaching consequences, impacting not only its domestic environment and population but also contributing to global climate change. The extensive use of coal in China has led to severe air and water pollution, with the World Bank estimating that China has 16 of the world's 20 most polluted cities. The burning of coal is the primary source of this pollution, releasing toxic substances such as arsenic, fluorine, polycyclic aromatic hydrocarbons, and mercury into the atmosphere.

China's coal mining industry also faces significant safety concerns, with a high rate of mining accidents and fatalities. The country's coal mines have the world's worst safety record, and the welfare cost of air pollution due to coal usage is estimated to be between 3% and 8% of China's GDP.

However, China has recognized the environmental and health impacts of its extensive coal usage and is taking steps to address them. The country has pledged to peak coal consumption by 2030 and achieve carbon neutrality by 2060. China is

US emissions and deregulation

The United States is one of the world's top polluters, with 6 billion tons of CO2 emitted in 2024. While the US has taken steps to reduce emissions, it has also had periods of deregulation, which have had mixed results.

History of US Environmental Policy

The US National Environmental Policy Act (NEPA) was signed into law in 1970 by President Richard Nixon, establishing a comprehensive national environmental policy and requiring an environmental impact statement for "major federal actions significantly affecting the quality of the environment." This was followed by the creation of the Environmental Protection Agency (EPA) later that year.

Since then, there have been significant achievements in environmental regulation, including increases in air and water quality and, to a lesser degree, control of hazardous waste. However, there has also been a backlash from business and politically conservative interests, which have limited increases to environmental regulatory budgets and slowed efforts to protect the environment.

Deregulation in the Power Sector

The US has a history of deregulation in the power sector, with attempts made in the 1990s to increase competition and reduce government control. This included the 1992 federal Energy Policy Act, which ended many regulations that had prevented open-market competition in transmission lines. This opened up the possibility for a restructuring of the power sector, with many states passing their own legislation to provide consumers with more choices in electricity providers.

Impact of Deregulation

Deregulation in the power sector has had both positive and negative impacts. On the one hand, it has laid the foundation for the integration of renewables into electricity generation and made the adoption of renewable-friendly policies more possible. For example, Texas's 1999 Public Utility Regulatory Act included provisions for a renewable portfolio standard and emissions reductions, while also promoting competition and low consumer prices.

However, deregulation can also go wrong, as seen in California's 2000-01 energy crisis, where supply and market disruptions caused prolonged rolling blackouts. This was attributed to a failure of deregulation without backstops, with large energy companies taking advantage of the weak regulatory environment to manipulate the market.

Current Efforts to Reduce Emissions

The current Biden administration has taken strong measures to protect the climate and the environment, including signing the Inflation Reduction Act, the largest climate investment in US history. This act includes provisions related to clean energy investments, tax credits for renewable projects, and initiatives to accelerate the transition to a low-carbon economy. The administration has also set goals to reduce US greenhouse gas emissions by 50-52% below 2005 levels by 2030 and achieve a net-zero emissions economy by 2050.

EU's cap-and-trade programs

The European Union (EU) created the world's first international cap-and-trade program in 2005 with the goal of reducing carbon emissions. The EU Emissions Trading System (EU ETS) is a key component of the EU's strategy to combat climate change and meet its emissions reduction targets. The program has been in place since 2005 and covers a wide range of economic sectors, including power plants, industrial facilities, transportation, and buildings.

Under the EU ETS, a cap is set on the total amount of greenhouse gas emissions allowed for the industries covered by the system. This cap is lowered over time, creating an incentive for companies to reduce their emissions and invest in cleaner technologies. Companies that exceed their allocated emissions cap must purchase additional allowances or face penalties. Companies that successfully reduce their emissions below the cap can sell or trade their excess allowances to other companies. This flexible mechanism allows companies to find the most cost-effective ways to reduce their emissions, encouraging innovation and efficient pollution reduction strategies.

The EU ETS operates through a combination of auctioning and allocation of emission allowances. The EU sets the overall emissions cap and distributes allowances to companies, either through auctions or direct allocation. The number of allowances available is reduced over time, tightening the cap and driving up the price of permits. This creates a financial incentive for companies to reduce their emissions, as permits become more expensive.

The EU ETS covers a significant portion of the EU's economy and has contributed to the region's progress in addressing climate change. In 2019, the EU estimated that the system would achieve a 21% reduction in emissions from covered sectors by 2020. The success of the EU ETS has influenced other regions to adopt similar cap-and-trade programs, recognising the potential for market-based mechanisms to drive emissions reductions.

The effectiveness of cap-and-trade programs, however, depends on various factors. Accurate data on emissions is essential for setting appropriate caps and monitoring compliance. Additionally, complementary policies, such as renewable energy standards and vehicle efficiency standards, can enhance the impact of cap-and-trade systems. While the EU ETS has shown progress, critics argue that caps could be set too high, potentially slowing the transition to cleaner energy sources.

India's low per capita emissions

India's per capita emissions are significantly below the global average. While India is one of the world's biggest CO2 emitters, its emissions per person are much lower than those of the US and China, the top two polluters. India's large population means that its total emissions are high, but when adjusted for population, its per capita emissions are relatively low.

India's per capita CO2 emissions have increased in recent decades, climbing from 0.4 metric tons in 1970 to 2.07 metric tons in 2023, a 6.7% increase from 2022 levels. However, India's per capita emissions remain lower than those of many developed countries. Per capita emissions tend to be higher in more economically developed countries, as they often rely more on carbon-intensive transportation, have a higher share of energy-intensive industries, and depend heavily on fossil fuels for power generation.

While India's total emissions are expected to rise as its economy grows, its per capita emissions may remain relatively low compared to developed countries, especially if it successfully invests in renewable energy projects. India's large population also means that its per capita emissions will be lower than countries with smaller populations but similar total emissions.

In summary, India's per capita emissions are low compared to other top polluting countries, and this is influenced by a range of factors, including population size, stage of development, and historical emissions. As India continues to develop, its total emissions may increase, but its per capita emissions may remain lower than those of developed countries, especially if it can reduce its reliance on fossil fuels.

Japan's energy efficiency

Japan is the biggest consumer of fossil fuels globally and the fifth-largest emitter of greenhouse gases. This is due to its high level of urban development and industry, which seems to prioritize growth over nature. However, Japan has also demonstrated a commitment to energy efficiency and reducing pollution to combat climate change.

Japan has been a Climate and Clean Air Coalition (CCAC) Partner since 2012 and has established itself as a global leader in advocating for short-lived climate pollutant (SLCP) reductions. This includes a focus on the lifecycle management of hydrofluorocarbons (HFCs), which are powerful industrial chemicals used for cooling and refrigeration. HFCs are expected to double in consumption by 2030, making them one of the fastest-growing greenhouse gases. Japan has stronger regulations on HFCs than most countries, and it launched the CCAC's Efficient Cooling Initiative to mobilize political support for action worldwide.

Japan's commitment to energy efficiency is also evident in its transportation sector. The country has continuously tightened emission standards for vehicles, focusing on high-emitting heavy-duty trucks and buses. All new diesel vehicles are now equipped with diesel particulate filters, and Japan introduced new fuel efficiency standards for small cargo vehicles in 2015, making them 26% more fuel-efficient than in 2012.

In addition to transport, Japan is making efforts to improve energy efficiency in the building sector. The Basic Energy Plan aims to realize the Net Zero Energy House (ZEH) concept in the majority of newly constructed houses by 2020 through efficient heating and cooling systems.

Japan is also working to reduce methane emissions from rice cultivation, promoting soil preparation techniques that involve applying rice straw compost instead of plowing-in rice straw, which has a higher methane emission factor.

Furthermore, Japan has made notable progress in waste management. It leads the world in the percentage of waste utilized in waste-to-energy facilities, burning 74.2% of its municipal solid waste for energy recovery. Japan operates over 380 waste-to-energy plants and is looking to export its expertise to other countries.

Overall, Japan is taking significant steps towards energy efficiency and pollution reduction, despite being one of the top emitters of greenhouse gases. The country has set ambitious goals and implemented various initiatives to combat climate change and reduce its environmental impact.
