The report details multiple instances where the George W. Bush administration intervened in federal scientific reporting to downplay the human role in global warming. Key examples include the removal of climate sections from EPA reports, the censorship of a USDA brochure on carbon sequestration, and the editing of scientific summaries by a non-scientist former oil industry lobbyist to increase perceived uncertainty. The document asserts that these actions undermined the integrity of federal agencies and contradicted the scientific consensus established by the IPCC and the National Academy of Sciences.

Nigeria is identified as the world's largest gas flarer, wasting approximately 2.5 billion cubic feet of associated gas daily, which results in an annual economic loss of US $2.5 billion. The report asserts that flaring has been generally illegal since 1984 under the Associated Gas Reinjection Act, yet continues through a lack of transparency regarding ministerial certificates. Environmental impacts include the emission of roughly 70 million metric tons of CO2 annually and the creation of acid rain that corrodes infrastructure. Health risks for local communities, specifically in Bayelsa State, include increased rates of premature death, child respiratory illnesses, asthma, and cancer due to exposure to particulate matter and benzene. The report criticizes the 'double standards' of the British colonial legacy and the failure of projects like Bonny LNG and the West African Gas Pipeline to prioritize the use of associated gas over non-associated gas.

The document assesses the environmental and health impacts of shipping emissions, noting that they are significantly less regulated than land-based sources. It provides data on global and regional emission inventories, specifically for Europe and the United States, and compares these to land-based mobile sources. The report details several cost-effective mitigation strategies, including the use of low-sulphur fuel, seawater scrubbing, engine modifications, selective catalytic reduction (SCR), and shore-side electrical power ('cold ironing').

The report outlines legislative strategies for U.S. states to increase vehicle efficiency, categorizing them into short-term options—such as HOV lane access for Alternative Fuel Vehicles (AFVs) and Hybrid Electric Vehicles (HEVs), state procurement mandates, and tire labeling—and long-term options, including tax incentives, 'pay-at-the-pump' insurance, and feebate programs. It argues that state action is necessary due to the economic burden of high oil prices, security risks associated with oil dependence, and environmental impacts like carbon dioxide emissions.

The testimony by the Clean Air Task Force (CATF) urges the U.S. Senate to oppose the Clear Skies Act (CSA), claiming its emission caps for sulfur, nitrogen, and mercury are too weak and implemented too late to protect public health and the environment. CATF presents modeling showing that alternative proposals, such as the Clean Power Act, would result in significantly fewer deaths by 2020 with negligible increases in retail electricity prices. The document further argues that CSA fails to address carbon dioxide emissions from power plants and would effectively repeal critical Clean Air Act provisions, including New Source Review and visibility protections for National Parks. It concludes that the EPA already possesses the authority to achieve greater gains through existing rules like the Clean Air Interstate Rule (CAIR) and mercury MACT standards.

The report ranks the 'Big Six' automakers—Honda, Nissan, Toyota, Ford, DaimlerChrysler, and General Motors—on their environmental performance, focusing on smog-forming and heat-trapping emissions. Honda consistently ranks as the cleanest, while General Motors has fallen to the bottom. The analysis highlights a trend where smog-forming pollution is improving due to regulation, but heat-trapping emissions remain stagnant. It specifically criticizes the use of regulatory loopholes, such as Flex-Fuel Vehicle (FFV) credits, which allow companies to artificially inflate fuel economy figures.

The document outlines a practice reported by Chevron U.S.A. Production Company to replace methane-rich natural gas used for blanketing water storage tanks with produced CO2-rich gas. This conversion prevents the formation of explosive mixtures in tanks while reducing the venting of methane into the atmosphere. A specific implementation across nine units at a water treatment plant resulted in an annual saving of 32,600 thousand cubic feet of methane gas. The document notes that while CO2-rich gas is a better alternative, it can form acid when dissolved in produced water, necessitating internal tank lining to prevent corrosion.

The document examines the environmental and social impacts of the aviation industry, noting that rapid growth in passenger and freight demand cancels out technological efficiency gains. It highlights the sector's contribution to climate change through greenhouse gases and radiative forcing, as well as local impacts like noise and air pollution. The authors propose a demand management strategy based on three pillars: internalising external costs via emission charges, shifting short-haul passengers to rail, and substituting physical travel with electronic communication. The paper concludes with nine specific policy recommendations, including a ban on night-time flights and the adoption of an 'environmental bubble' concept for airports.

The report documents that fine particle pollution from U.S. power plants causes nearly 24,000 premature deaths annually, including 2,800 from lung cancer, and 38,200 non-fatal heart attacks. It argues that the Bush administration's 'Clear Skies' proposal is insufficient compared to the Clean Air Act or the more stringent Jeffords bill, which could avoid 22,000 deaths per year. The analysis highlights that elderly populations, children, and communities of color—particularly in the Midwest and Southwest—are disproportionately affected.

The report argues that California can significantly reduce its global warming impact by mandating the adoption of existing and near-term vehicle technologies. Modeling shows that currently available improvements in engines, transmissions, and air conditioning could reduce fleet average heat-trapping emissions by 20%, while advanced technologies available within five years could achieve a 40% reduction. These improvements are presented as cost-effective, with fuel savings offsetting initial costs within a few years, and would provide a model for other U.S. states and Canada.

The report calculates that between 1882 and 2002, ExxonMobil emitted 21.53 billion tonnes of carbon equivalent, representing approximately 5% of global CO2 emissions. It argues that the company has actively undermined climate science and the Kyoto Protocol despite increasing production to record levels after scientific consensus on human-induced climate change was established. The findings link these emissions to 3.4%-3.7% of human-attributable global temperature increases and 2% of sea-level rise, with the latter projected to reach 3.2%-3.6% by the year 2200.

The Intelligent Travel project in York tested personalised travel planning on 5,701 households, resulting in a 16 percentage point reduction in car trips and a 28 per cent reduction in car distances driven among the intervention group. The study found that targeted incentives, particularly free bus passes and pedometers, effectively increased bus and walking trips, while cycling and car-sharing incentives had less impact. The report argues that such 'soft' behavioural interventions are highly cost-effective compared to traditional road-building schemes and can be scaled up to significantly reduce urban congestion and air pollution.

WRI's fiscal year 2002 CO2 emissions were 1,306 metric tons, representing a 3.5% reduction from 2001. The primary emission sources were purchased electricity (42%) and air travel (40%). While air travel emissions have decreased to 1% below 2000 levels, electricity emissions have risen 24% since 2000, largely due to increased cooling requirements from another tenant in WRI's non-separately metered building. WRI has adjusted historical data using improved methodologies and now holds a surplus of carbon offsets. To maintain its commitment, WRI is exploring new ways to fund offsets and has published the 'Working 9 to 5 on Climate Change' guide to help other organizations reduce their footprints.

The Union of Concerned Scientists (UCS) graded U.S. states on their commitment to renewable energy, finding that 34 states received failing grades (D or F) and only 16 passed. While 19 states have enacted standards or funds projected to add 15,215 MW of capacity by 2017, the gains are highly concentrated, with California and Texas accounting for nearly 60 percent of forecasted new development. The report argues that current state-level efforts are insufficient compared to the technical potential of wind, solar, bioenergy, geothermal, and landfill gas, and advocates for a national renewable electricity standard to achieve more equitable and cost-effective energy generation.

The document outlines the causes and consequences of global climate change, highlighting the role of greenhouse gas emissions and the influence of the fossil fuel lobby. It categorizes career paths for scientists and engineers into four areas of positive contribution: understanding the problem, technological solutions, economic solutions, and social/political solutions, while warning against the influence of vested interests.

The report details how African Americans are disproportionately exposed to power plant emissions due to residential concentration in urban centers and proximity to facilities. It links these emissions to higher rates of asthma, infant mortality, and mercury exposure, while highlighting the compounding effects of poverty and lack of healthcare. The authors advocate for new legislation to reduce sulfur dioxide, nitrogen oxides, mercury, and carbon dioxide, and specifically call for the elimination of the 'grandfather' exemption in the Clean Air Act's New Source Review program.

The report evaluates the environmental performance of the 'Big Six' automakers—Honda, Toyota, Nissan, Ford, General Motors, and DaimlerChrysler—using government data on smog-forming pollutants and greenhouse gases. Honda is ranked as the cleanest, while DaimlerChrysler is the dirtiest. The analysis highlights a significant pollution gap between cars and trucks, noting that trucks are permitted to emit more pollutants under current regulations. While smog-forming emissions decreased across the industry due to the National Low Emission Vehicle (LEV) program, global warming gas emissions increased, driven by a shift toward larger, less efficient vehicles. The report argues that voluntary corporate commitments, such as Ford's effort to reduce truck emissions, can improve rankings, but emphasizes that government regulation is necessary for industry-wide progress.

The report details how power plant emissions—including particulate matter, ozone, sulfur dioxide, and mercury—disproportionately harm children due to their developing physiology and higher activity levels. It links these pollutants to asthma, stunted lung growth, neurological deficits, and infant mortality, while advocating for nationwide emission caps and a transition to cleaner energy.

The report highlights that six Midwest states (Minnesota, Wisconsin, Michigan, Illinois, Indiana, and Ohio) are home to 140 power plants that release approximately 2% of global man-made CO2 and 25% of all US power plant CO2. It predicts that without aggressive emissions reductions, the region could see temperature increases of 5-10°F in the 21st century, leading to significant risks for the Great Lakes water levels, crop yields, and human health. The document advocates for cleaning up old coal plants, transitioning to renewable energy, and increasing individual energy efficiency to mitigate these risks.

The Clean Air Task Force argues that the National Coal Council's claim that 40,000 MW of capacity could be recovered from old coal plants by relaxing New Source Review (NSR) rules is flawed. The report asserts that a boom in new natural gas generation—estimated at 260,000 MW likely to come online by 2005—negates the need for such recovery. It further claims that recovering capacity from old plants would be expensive and difficult, as most deratings occur in small increments across 1,200 units. Finally, it argues that NSR enforcement provides far greater emission reductions than the efficiency (heat rate) improvements proposed by the industry.
