What You'll Learn
Carbon dioxide (CO2) is a greenhouse gas
CO2 enters the atmosphere through the burning of fossil fuels, solid waste, trees and other biological materials, and certain chemical reactions, such as cement production. Human activities, such as burning fossil fuels, have led to a significant increase in atmospheric CO2 concentrations. In 2024, the global average atmospheric carbon dioxide concentration reached a record high of 422.7 to 422.8 parts per million (ppm). This represents a 50% increase compared to pre-Industrial Revolution levels.
The rate of increase in atmospheric CO2 over the past 60 years is about 100 times faster than previous natural increases, such as those that occurred at the end of the last ice age. The ocean has absorbed a substantial amount of this additional CO2, leading to a 30% increase in its acidity.
CO2 absorbs energy at wavelengths between 2,000 and 15,000 nanometers, overlapping with infrared energy. As CO2 absorbs this energy, it vibrates and re-emits it as infrared energy in all directions, contributing to the greenhouse effect. This effect has been observed in experiments where infrared cameras are used to detect heat from a candle in a closed tube filled with CO2. The camera detects the heat clearly in ambient air, but the image blurs when the tube is filled with CO2, indicating that the CO2 molecules have absorbed and scattered the heat.
The increase in atmospheric CO2 concentrations has significant implications for the Earth's climate. According to the NOAA Global Monitoring Laboratory, carbon dioxide alone is responsible for about 80% of the total heating influence of all human-produced greenhouse gases since 1990.

CO2 is released by burning fossil fuels
Carbon dioxide (CO2) is a greenhouse gas that is essential for maintaining Earth's natural greenhouse effect and keeping the average global surface temperature above freezing. However, the excessive release of CO2 into the atmosphere has led to a rapid increase in atmospheric CO2 concentrations, contributing significantly to climate change.
One significant source of CO2 emissions is the burning of fossil fuels, such as coal, oil, and natural gas. Fossil fuels are primarily composed of carbon and hydrogen. When these fuels are burned, oxygen combines with carbon to form CO2 and with hydrogen to form water (H2O). These combustion reactions release heat energy, which is utilised for various purposes, including electricity generation and transportation.
The burning of fossil fuels has been a prevalent practice since the Industrial Revolution, significantly contributing to the rise in atmospheric CO2 levels. According to the Global Carbon Budget 2024, annual emissions of CO2 from fossil fuel combustion have increased from approximately 11 billion tons per year in the 1960s to an estimated 37.4 billion tons in 2024. This surge in emissions is primarily driven by the energy demands of various sectors, including commercial, industrial, residential, transportation, and electric power industries.
The transportation sector, heavily reliant on petroleum fuels, is a major contributor to CO2 emissions. In 2023, the transportation industry was responsible for the largest share of energy-related CO2 emissions in the United States. Additionally, the industrial sector, including electricity generation, also plays a significant role in CO2 emissions, with natural gas being a prominent source.
The release of CO2 from burning fossil fuels has far-reaching consequences. The excess CO2 is absorbed by the oceans, leading to ocean acidification. This process lowers the ocean's pH, impairing the ability of marine organisms like corals, crabs, and snails to build their shells and skeletons. Furthermore, the rising atmospheric CO2 concentrations contribute to the overall increase in global temperatures, with potential impacts on ecosystems, weather patterns, and human health.

Greenhouse gas emissions cause global warming
Carbon pollution refers to the emission of carbon-containing substances into the environment, causing harm to human health, ecosystems, and the climate. One of the most significant forms of carbon pollution is carbon dioxide (CO2), a greenhouse gas. Greenhouse gases, including carbon dioxide, methane, and nitrous oxide, are responsible for the Earth's natural greenhouse effect, which helps maintain a habitable climate by absorbing and re-emitting heat. However, human activities have significantly increased the concentration of these gases in the atmosphere, leading to global warming and climate change.
Atmospheric carbon dioxide levels have been steadily rising due to human activities, particularly the burning of fossil fuels, deforestation, and industrial processes. Since the Industrial Revolution, carbon dioxide concentrations have increased by 50%, with the rate of increase being 100-200 times faster than previous natural changes. This rapid rise has resulted in unprecedented global warming. The years with the largest annual carbon dioxide growth tend to be associated with strong El Niños, which lead to high temperatures.
In addition to carbon dioxide, other greenhouse gases contribute to global warming. For example, methane is produced by livestock farming and the decay of organic waste in landfills, while nitrous oxide is emitted from nitrogen-based fertilisers and certain industrial processes. These gases have a warming effect that is much stronger than that of carbon dioxide, with some having up to 23,000 times greater warming potential.
The impact of greenhouse gas emissions on global warming is evident through various indicators, such as rising global temperatures, melting ice caps, and extreme weather events. Since 1990, the total warming effect from greenhouse gases added by humans to the Earth's atmosphere has increased significantly, with carbon dioxide alone contributing to a 42% increase in the warming effect. This warming has led to the Arctic and glaciated regions, such as the Himalayas, becoming particularly vulnerable to melting.
To mitigate global warming, it is essential to reduce greenhouse gas emissions. This can be achieved through various means, such as transitioning to renewable energy sources, improving energy efficiency, adopting carbon capture technologies, and implementing waste management practices that reduce methane emissions. By addressing greenhouse gas emissions, we can work towards stabilising global temperatures and minimising the impacts of climate change.

Transportation is a major source of carbon pollution
Carbon pollution refers to carbon dioxide (CO2) emissions, which are released when fossil fuels such as coal, oil, and natural gas are burned. CO2 is a greenhouse gas, and its buildup in the Earth's atmosphere is causing global warming and climate change. Transportation is a significant contributor to carbon pollution, as the burning of gasoline, diesel fuel, and jet fuel used to power vehicles releases large amounts of CO2. In the United States, the transportation sector is the largest source of greenhouse gas emissions, with vehicles such as cars, trucks, airplanes, and railroads contributing to emissions.
The impact of transportation on carbon pollution is substantial, with the sector accounting for about two-fifths of domestic emissions from burning fossil fuels in the US. While there have been efforts to reduce emissions, such as tighter fuel economy standards and the promotion of electric vehicles, transportation emissions have continued to rise in recent years. Before the coronavirus pandemic, CO2 emissions from transportation had been increasing, and they now constitute a significant portion of total US greenhouse gas emissions.
There are several approaches to reducing carbon pollution from transportation. These include the development and use of low-carbon fuels, improvements in vehicle technology, and strategies to reduce the number of vehicle miles traveled. Operating vehicles more efficiently, such as through improved fuel economy, can also help reduce emissions. Additionally, individuals can contribute by choosing more sustainable transportation options, such as biking, using public transportation, or driving electric vehicles.
The Environmental Protection Agency (EPA) in the United States is taking action to address carbon pollution from transportation. They have implemented standards for fuel economy and emissions for vehicles, including cars, light-duty trucks, and heavy-duty trucks. These standards aim to reduce greenhouse gas emissions and improve fuel efficiency. The EPA also provides resources to help consumers make environmentally friendly vehicle purchases and encourages the use of low-emission vehicles by federal agencies.
Internationally, the EPA has collaborated with the Federal Aviation Agency and the United Nations' International Civil Aviation Organization (ICAO) to develop carbon dioxide emissions standards for aircraft. These standards are crucial in maintaining the worldwide acceptance of US-manufactured airplanes. By addressing carbon pollution from transportation, the EPA is contributing to the global effort to mitigate climate change and reduce the environmental impact of the transportation sector.
