The burning of fossil fuels for energy is a significant contributor to air pollution. Fossil fuels, including coal, oil, and natural gas, emit hazardous air pollutants such as sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants have detrimental effects on both the environment and human health. Communities of color and low-income communities are disproportionately impacted by the environmental and health consequences of fossil fuel usage.

In 2022, 60% of electricity in the United States was generated by burning fossil fuels, primarily coal and natural gas. The industrial sector, which includes power plants, is responsible for a large share of greenhouse gas emissions. When indirect emissions from electricity use are attributed to the industrial sector, their contribution to air pollution becomes even more significant.

The combustion of fossil fuels releases carbon dioxide, a potent greenhouse gas. In 2021, carbon dioxide accounted for about 79% of the country's total greenhouse gas emissions. Carbon dioxide emissions from fossil fuel combustion increased by 8% in 2022 compared to 2020. This rise in emissions was driven by the economic recovery after the COVID-19 pandemic.

In addition to carbon dioxide, the extraction, transportation, and refining of fossil fuels can lead to oil spills, water pollution, and hazardous waste. Fracking, for example, utilizes large volumes of water, and the resulting wastewater can contaminate groundwater and drinking water sources with toxic substances.

To reduce air pollution from the energy industry, a transition to cleaner fuels and industrial processes is necessary. This includes adopting renewable energy sources such as wind and solar power, improving fuel efficiency, and electrifying transportation. By addressing air pollution at its source, we can also mitigate the health impacts associated with poor air quality, such as respiratory and cardiovascular diseases, neurological damage, and cancer.

Cars, trucks, ships, trains, and planes are all part of the transport sector, which is the fastest-growing contributor to climate emissions due to rapid motorization and growth in energy use. In 2010, the transport sector accounted for 14% of global greenhouse gas emissions, with land transport, including cars, being the main driver of growth.

Cars

Cars are major contributors to air pollution, releasing about 1.7 billion tons of greenhouse gases into the atmosphere each year. The burning of fossil fuels like gasoline by cars releases carbon dioxide and other greenhouse gases, causing global warming. Cars also emit pollutants that cause health complications, including cancer, asthma, eye irritation, poisoning, heart disease, and birth defects. While it is difficult to determine the exact percentage of air pollution caused by cars, studies indicate that 25% of cars and trucks cause about 90% of pollution from vehicles.

Trucks

Trucks are also significant contributors to air pollution, particularly in the freight transportation sector. The EPA has implemented regulations to reduce greenhouse gas emissions from trucks, including fuel economy standards for light and heavy-duty trucks. These regulations are projected to reduce GHG emissions and improve fuel efficiency.

Ships

The shipping industry contributes about 3% of all greenhouse gas emissions, with container ships releasing about 1 billion metric tons of carbon dioxide into the air each year. The industry has been pressured to reduce its environmental impact, with some companies investing in more sustainable fuels and vessels.

Trains

Trains are a low-carbon mode of transport, emitting around 35 grams of CO2 per kilometer, compared to 170 grams for the average petrol car. Taking a train instead of a car or a flight can significantly reduce carbon emissions, making it a more environmentally friendly option.

Planes

Aviation produced 2.4% of total CO2 emissions in 2018, and its climate impact has been growing due to the increasing number of passengers and freight. Aircraft GHG emissions contribute to air pollution and endanger public health and welfare. Efforts are being made to mitigate emissions, with new aircraft meeting or exceeding CO2 emission requirements.

Commercial and residential: Fossil fuels, electricity, waste

The commercial and residential sectors contribute significantly to air pollution through fossil fuel combustion, electricity consumption, and waste generation.

Fossil Fuels

Fossil fuels, such as coal, natural gas, and petroleum, are the primary sources of energy for these sectors. In 2023, fossil fuels accounted for about 84% of the US's total primary energy production, with coal alone contributing about 11%. The combustion of these fuels releases carbon dioxide (CO2), a major greenhouse gas. From 2020 to 2022, CO2 emissions from fossil fuel combustion increased by 8%, contributing to global warming and climate change.

Electricity

The commercial and residential sectors are major consumers of electricity, with buildings using 75% of the electricity generated in the US. In 2023, about 60% of the electricity generated at utility-scale facilities was from fossil fuels. This means that a significant portion of the electricity consumed by these sectors results in indirect greenhouse gas emissions. When indirect emissions from electricity use are included, the commercial and residential sectors' emissions increase substantially.

Waste

Waste handling and management in the commercial and residential sectors also contribute to air pollution. While specific data on the impact of waste from these sectors is limited, it is known that waste management practices, such as incineration and landfill operations, can release pollutants into the air. These pollutants include hazardous chemicals and particulate matter, which can have detrimental effects on human health and the environment.

It is important to note that while the commercial and residential sectors are significant contributors to air pollution, efforts have been made to improve air quality. The transition to cleaner fuels, increased use of renewable energy sources, and the implementation of regulations and technological advancements have all played a role in reducing emissions and improving air quality over the years.

Construction: Damaging land and water

While it is challenging to attribute a specific percentage of air pollution to industries, human activities, including those from industrial sectors, significantly contribute to air pollution. In the United States, for instance, the Clean Air Act has played a pivotal role in reducing air pollution since its enactment in 1970. Despite this, industrial activities, along with other factors like vehicle emissions and energy consumption, continue to adversely impact air quality.

The construction industry has a significant impact on the environment, particularly concerning land and water resources. Here are some ways in which construction activities can lead to environmental damage:

• Soil Erosion and Sedimentation: Construction activities that involve land grading, trenching, and excavating can result in soil erosion and sedimentation issues. When soil is disturbed during construction, it becomes more susceptible to erosion, especially when proper erosion control measures are not implemented. This eroded soil, or sediment, can then be transported by wind or water, leading to the degradation of nearby land and water bodies.
• Water Pollution: Construction sites are susceptible to water damage and can also be a source of water pollution. Water bodies near construction sites are at risk of pollution from various sources, including fuel and chemical spills, stormwater runoff, and sedimentation. For example, fuel and chemical leaks from improperly stored tanks can contaminate nearby water sources. Stormwater runoff from construction sites can carry pollutants, such as silt, excess nutrients, and chemicals, into nearby streams, rivers, or lakes, leading to eutrophication and adverse effects on aquatic life.
• Compaction and Agitation of Topsoil: The use of heavy machinery and equipment during construction can compact the ground, reducing its permeability and increasing surface runoff. This compaction also agitates the topsoil, mobilizing silt particles that can be carried away by water, leading to siltation issues in nearby water bodies.
• Landslides: Human activities, including construction, have been implicated in the increasing incidence of landslides in certain regions. In Malaysia, for instance, construction practices have been identified as a significant contributor to the country's high number of landslides.
• Wetland Destruction: Wetlands provide invaluable ecological services, such as flood mitigation, erosion control, water quality improvement, and habitat for diverse species. However, construction activities that involve the destruction or alteration of wetlands can have detrimental effects on these vital ecosystems, leading to a loss of their ecological functions.

To mitigate these impacts, it is essential to implement sustainable construction practices and adopt erosion and sedimentation control plans. Additionally, proper water management procedures, forward planning, and staff training in environmental practices can help reduce the risk of water pollution and other environmental damages associated with construction projects.
