The document outlines the environmental and health risks associated with hydraulic fracturing (fracking), specifically highlighting the contamination of drinking water, high greenhouse gas emissions from methane leaks and transport, and the potential for carcinogenic effects on nearby populations. It concludes that natural gas is not a viable transition fuel and calls for a shift toward renewable energy in Canada.

The report examines the health and economic impacts of Alberta's heavy reliance on coal-fired electricity, which generated 64 per cent of the province's electricity in 2012. Using the Illness Cost of Air Pollution (ICAP) model and other data, the authors estimate that coal plants contribute to hundreds of premature deaths and thousands of emergency department visits annually. The report identifies a wide range of pollutants, including nitrogen oxides, sulphur dioxide, mercury, and particulate matter, which affect respiratory, cardiovascular, and neurological health. Economically, the report argues that the true societal cost of coal—including health damages and the social cost of carbon—ranges from 3.6 to 13.7 ¢/kWh, far exceeding the market pool price of 6.6 ¢/kWh. The authors conclude that the current system effectively subsidizes coal power at the expense of public health and recommend that Alberta accelerate the retirement of coal units beyond the 50-year limit allowed by federal regulations.

The report finds that the US Midwest has experienced a significant increase in dangerously hot and humid summer days since the 1940s and 1950s. This trend increases the risk of heat-related illnesses and deaths, particularly for vulnerable populations such as the elderly, children, and urban residents. The analysis, covering 10 cities across eight states, indicates that rising nighttime temperatures and more frequent heat waves exacerbate health risks. Projections suggest that without significant carbon emission reductions, the region will face a substantial increase in days exceeding 90°F and 100°F by the end of the century.

The report analyzes the relationship between rising temperatures and ground-level ozone formation, projecting that climate change will increase ozone concentrations and exacerbate respiratory health issues. Using the EPA's BenMAP model, the authors estimate that by 2020, the 'climate penalty' could result in 2.8 million additional acute respiratory symptoms and $5.4 billion in health costs. By 2050, these impacts are projected to rise significantly, with 11.8 million additional respiratory symptom occurrences. The report emphasizes that while precursor emissions are declining, warming temperatures may offset these gains, particularly in California, the Midwest, and the Mid-Atlantic.

The document details the severe health risks of diesel particulate matter, including 21,000 annual deaths and increased cancer risks. It advocates for the Diesel Emission Reduction Act (DERA) to clean up the existing fleet of 11 million heavy-duty engines and proposes the Clean Construction Act of 2011 to integrate emission controls into federally funded transportation projects, capping costs at 1% of project totals.

The Clean Air Task Force (CATF) proposes a 'Clean Construction' policy for U.S. transportation projects, requiring the use of emission control technologies like Diesel Particulate Filters (DPF) in PM2.5 non-attainment and maintenance areas. The proposal suggests funding these upgrades through project change orders, capped at 1% of total project costs, to mitigate severe health risks associated with diesel pollution while ensuring a fair bidding process for contractors.

The report estimates that fine particle pollution from existing U.S. coal plants would cause nearly 13,200 deaths and over 20,000 heart attacks in 2010, with a total monetized health cost exceeding $100 billion per year. While emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) have declined since 2004 due to the installation of over 130 scrubbers and regulations like the Clean Air Interstate Rule (CAIR), the burden remains high, particularly in the Midwest, South, and Mid-Atlantic regions. The authors argue for a stronger Transport Rule and national emission caps to further reduce these health risks.

In a letter to the Minister of Water and Environmental Affairs, Gareth Morgan MP disputes government claims that air quality in St Helena Bay is safe. He argues that fish factories emit toxic hydrogen sulphide (H2S) and sulphur dioxide (SO2), which accumulate due to factory operating patterns and cause severe respiratory and neurological damage. Morgan highlights the vulnerability of children and the lack of government investigation into health impacts, citing international studies to link these emissions to conditions such as Bronchiolitis Obliterans and potential carcinogenic effects. He demands that factories stop using rotten fish, improve cleanliness, and install scrubber systems.

The Clean Air Task Force (CATF) supports the EPA's proposed Transport Rule to replace the judicially invalidated Clean Air Interstate Rule (CAIR) but argues it should be strengthened to further reduce sulfur dioxide (SO2) and nitrogen oxides (NOx). CATF specifically advocates for the passage of S. 2995, the Clean Air Act Amendments of 2010 (CAAA of 2010), asserting it would deliver greater emissions reductions, save more lives, and provide more regulatory certainty than the Transport Rule alone. The testimony details the severe health and environmental impacts of power plant emissions, including premature death from fine particulate matter, acid rain damage to eastern ecosystems, and ozone-related crop losses.

A reworked analysis by the Institute for Policy Integrity indicates that transitioning large buildings in New York City away from residual heating oil could save up to 259 lives annually. The report utilizes three distinct methodologies—including nickel concentration comparisons and city data—to arrive at consistent estimates regarding the health impacts of soot and toxic chemicals released by residual oil boilers.

The document outlines how transitioning away from fossil fuels reduces health costs via three primary channels: mitigating air and water pollution, reducing obesity through active transportation, and lowering climate change risks. It provides specific 2005 cost estimates for health damages from coal-fired plants ($62 billion), natural gas plants ($740 million), and vehicles ($56 billion). The text emphasizes that obesity currently represents a larger health cost burden in the United States than air quality impacts and suggests that energy policies should be evaluated based on total costs and benefits per unit of energy or distance.

The ADAPTE project investigates the interaction between air pollution and extreme weather on human health in Latin American cities, specifically focusing on Mexico City, Santiago, Buenos Aires, and Bogotá. Initial findings indicate that suspended particles and nitrogen oxides in these cities significantly exceed WHO standards, with vulnerability varying by age, sex, income, and season.

The document details the health risks associated with occupational exposure to diesel exhaust, specifically particulate matter, and advocates for the use of Diesel Particulate Filters (DPFs) to retrofit older engines.

The document presents findings from the 'Corbett and Winebrake Study', which estimates that particulate matter (PM) from ocean-going ships caused approximately 60,000 premature deaths globally in 2002. The study indicates that these deaths are expected to increase by 40% by 2012 (or 2020 in some case analyses) due to growth in shipping traffic. Regional analysis shows that Europe and the Mediterranean, East Asia, and South Asia are the most heavily impacted areas. The document argues that the societal cost of these deaths exceeds $300 billion annually based on US EPA valuations, far outweighing the costs of emission reductions. Consequently, it urges the IMO Sub-Committee on Bulk Liquids and Gases to recommend stringent emission limits for the amended MARPOL Annex VI.

The Clean Air Task Force (CATF) conducted monitoring in Austin, Boston, New York City, and Columbus to assess diesel exhaust exposure during commutes. The study found that commuters in cars, buses, and trains are exposed to diesel particle levels significantly higher than ambient outdoor air, with the highest concentrations occurring in the presence of heavy truck traffic or when trains are pulled by locomotives. The report highlights that while commuting accounts for only about 6% of a person's day, it may contribute over half of their daily exposure to ultrafine particles. To mitigate these risks, the report recommends retrofitting existing diesel engines with diesel particulate filters (DPFs), which can reduce particle emissions by up to 90%.

The document summarizes recent emissions inventories and health studies to demonstrate that shipping emissions are growing rapidly and significantly impacting human health. It highlights a global inventory projecting a 4.1% annual growth in emissions through 2040 and a North American inventory projecting 5.9% annual growth. The text argues that current and proposed IMO regulations are insufficient to offset this growth and calls for steep, fleet-wide reductions. Additionally, it cites California Air Resources Board (CARB) data showing that premature deaths attributed to ocean-going ships in California are predicted to more than double by 2020.

The report finds that diesel construction equipment in California causes over 1,100 premature deaths and more than $9 billion in annual public health costs. It identifies excavators, tractors/loaders/backhoes, and crawler tractors as the highest polluters and highlights the South Coast air basin as the most affected region. The authors advocate for a regulatory regime to retire old equipment and install retrofit technologies to reduce particulate matter and nitrogen oxides.

The Clean Air Task Force argues that the EPA's proposed particulate matter (PM2.5) standards fail to provide an adequate margin of safety, potentially resulting in 10,000 more avoidable deaths per year than a more stringent 12 ug/m3 annual standard. The testimony asserts that protective standards are achievable through affordable technologies, specifically targeting sulfur dioxide (SO2) from power plants and carbon emissions from diesel fleets. It criticizes the Clean Air Interstate Rule (CAIR) for providing reductions that are "too little, too late" and for creating regulatory barriers that discourage states from pursuing additional cost-effective power plant reductions. The document advocates for a national SO2 cap of 2 million tons per year and the full funding of the Diesel Emission Reduction Act of 2005 to facilitate the retrofit of existing diesel engines.

The Clean Air Task Force (CATF) advocates for the Diesel Emissions Reduction Act of 2005 (DERA), a proposed $1 billion federal grant and loan program to reduce diesel fine particle (PM2.5) emissions. CATF highlights that diesel exhaust causes 21,000 premature deaths annually and that existing engines will remain in service for decades, necessitating funding for retrofits, rebuilds, and repowerings to meet air quality standards and provide immediate climate benefits by reducing black carbon.

The report quantifies the health damages caused by diesel particulate matter (PM2.5) and other emissions across the U.S., highlighting significant risks of premature death, lung cancer, and respiratory illness. It estimates that 21,000 people die prematurely each year in the U.S. due to mobile diesel sources. The document proposes a three-phase retrofit strategy to reduce diesel PM by 85% by 2020, which could avoid approximately 91,000 premature deaths by 2030. It identifies urban areas and 'hotspots'—such as near bus depots and highways—as having significantly higher risks than rural areas. The report also details the effectiveness of retrofit technologies, such as diesel particulate filters (DPF) and closed crankcase filtration, particularly for improving air quality inside school buses.
