The author examines the logistical impossibility of evacuating a city the size of Houston (2.3 million people) during Hurricane Harvey and warns that European cities of similar or larger scales face comparable risks. The text highlights how a lack of zoning and the destruction of marsh lands increased Houston's vulnerability to flooding. To mitigate such risks, the author proposes that European governments use financial incentives to reduce urban density by encouraging companies and residents to relocate to smaller areas, while investing in sustainable public transportation to facilitate rapid evacuations.

The analysis concludes that while Hurricane Harvey was an extremely rare event, global warming increased the intensity of its precipitation by approximately 15% and made such an event about three times more likely. Observational data and climate models indicate a trend of increasing extreme precipitation along the US Gulf Coast, often exceeding the standard Clausius-Clapeyron scaling. The study emphasizes that while the storm's rarity makes it difficult to attribute its existence to climate change, the increased rainfall intensity contributed significantly to the flooding in Houston, which was further exacerbated by urban development and subsidence.

The document asserts that federal light-duty vehicle standards set by the EPA and NHTSA in 2012 benefit Texas through fuel savings, job creation, and emissions reductions. By 2030, the average Texas household is projected to be $3,250 richer due to gas savings outweighing the upfront cost of more efficient vehicles. To date, Texas has saved $3 billion, and the standards are expected to create 24,400 new jobs in the state. Environmentally, the standards eliminate global warming emissions in Texas nearly equivalent to those generated by providing electricity to Houston.

The document details the health impacts of oil and gas industry air pollution in Texas, noting that toxic emissions increase cancer risks in 82 counties and ozone smog causes approximately 145,000 annual asthma attacks in children. It highlights that 2.3 million Texans and over 900 schools are located within a half-mile of active operations, and argues that the suspension of EPA standards for leak inspections further endangers the population.

The document argues that the EPA's proposed 20-month delay of the Chemical Disaster Rule is unlawful, arbitrary, and dangerous to public health and national security. It contends that the delay violates the Clean Air Act's three-month limit on reconsideration stays and ignores the agency's own findings regarding the urgent need for updated risk management programs to prevent catastrophic chemical releases.

The report identifies a 'double jeopardy' for residents of east Houston's Harrisburg/Manchester and Galena Park communities, who face both daily chronic exposure to toxic air pollutants and a high risk of acute catastrophic chemical accidents. Using EPA data, the study finds that these marginalized communities have significantly higher toxic concentrations, cancer risks, and respiratory hazards than the more affluent West Oaks/Eldridge and Bellaire neighborhoods. The authors attribute these disparities to a lack of citywide zoning in Houston and the concentration of high-risk industrial facilities in low-income areas, recommending stricter regulations on safer chemicals, improved fenceline monitoring, and the implementation of formal health-impact assessments.

The report identifies a 'double jeopardy' for residents of Harrisburg/Manchester and Galena Park in east Houston, who face both higher daily exposure to toxic air pollutants and greater proximity to high-risk chemical facilities than residents of West Oaks/Eldridge and Bellaire in west Houston. This disparity results in significantly higher cancer and respiratory illness risks for east Houston residents, exacerbated by a lack of comprehensive zoning laws and socioeconomic determinants.

The report identifies a 'double jeopardy' for residents of Harrisburg/Manchester and Galena Park in east Houston, who face both significantly higher daily exposure to toxic air pollutants and a greater risk of catastrophic chemical accidents due to their proximity to high-risk industrial facilities. In contrast, wealthier communities in west Houston, such as Bellaire and West Oaks/Eldridge, have far lower exposure levels and fewer nearby hazardous facilities. The document advocates for systemic regulatory changes, including the adoption of safer technologies, improved emergency communication, and the implementation of health impact assessments to address these environmental justice disparities.

The report finds that millions of Latinos in the US are disproportionately exposed to toxic air pollutants and ozone from oil and gas infrastructure, leading to significant health burdens. It highlights that 1.81 million Latinos live within a half-mile of such facilities and 1.78 million live in counties where cancer risks exceed EPA concern levels. The document argues that poverty and lack of health insurance exacerbate these risks, and calls for the EPA to regulate existing facilities, not just new ones, to protect public health and address climate change.

The report finds that millions of Latinos are exposed to toxic air pollutants and ozone smog from oil and gas facilities, leading to elevated cancer risks and childhood asthma attacks. These health threats are exacerbated by higher poverty rates and lower health insurance coverage within Latino populations. The authors argue for comprehensive EPA regulations covering both new and existing oil and gas infrastructure to reduce methane and toxic emissions.

The document details the exposure of the Manchester community in Houston to hazardous air pollutants emitted by nearby industrial facilities, including oil refineries and chemical plants. It identifies six specific toxic substances—1,3-Butadiene, Benzene, Ethylbenzene, Styrene, Toluene, and Xylene—and describes their potential short- and long-term health effects, such as cancer and respiratory issues. The report emphasizes that this 'front-line' community, characterized by high minority and low-income populations, faces disproportionate environmental burdens and lacks the resources to hold polluters accountable.

The document highlights the exposure of Manchester, Houston residents—a predominantly minority and low-income community—to toxic air pollutants from nineteen industrial facilities. It details the specific health risks associated with six hazardous air pollutants regulated under the Clean Air Act and argues for a shift in the burden of proof from the community to the polluters regarding health impacts.

Climate Central's analysis of U.S. Forest Service records shows that the average annual number of large wildfires in the western U.S. more than tripled between the 1970s and 2010s, with the area burned increasing more than six-fold. The report attributes these trends to rising temperatures, decreased snowpack, and earlier snowmelt. Projections using the Keetch-Byram Drought Index (KBDI) suggest that high-risk fire days will increase substantially by 2050, particularly in Southwestern states. The report also highlights the growing risk to populations living in the wildland-urban interface (WUI) and the health impacts of wildfire smoke.

The community of Manchester in Houston, Texas, faces significant public health threats due to a dense concentration of industrial facilities, including oil refineries and chemical plants. Residents, who are 98 percent minority and 65 percent low-income, are exposed to hazardous air pollutants such as benzene and 1,3-butadiene. The document highlights the disproportionate burden of pollution on low-income communities of color and calls for local officials to prioritize public health and safety in fence-line communities.

The document examines the potential for mid-level ethanol blends (E25 to E40) to improve fuel efficiency and reduce greenhouse gas emissions in the U.S. transportation sector. It highlights that a significant portion of the existing vehicle fleet and fuel infrastructure can accommodate these blends with moderate costs. Research indicates that increasing ethanol content can enhance engine performance and that a nationwide E25 blend could reduce transportation GHG intensity by 5 to 9 percent.

The document examines the potential for mid-level ethanol blends (E25-E40) to serve as high-octane fuels, reducing GHG emissions and increasing efficiency for both existing and future internal combustion engines. It highlights that while infrastructure and 'blend wall' challenges exist, a significant portion of the current U.S. fleet—including 17.4 million FlexFuel Vehicles and 80% of cars newer than 2001 (for E15)—can accommodate higher blends. The text details the role of ethanol in preventing engine knock, the lifecycle GHG benefits of corn and cellulosic ethanol, and the DOE's Optima Initiative aiming to reduce petroleum consumption by 30% by 2030.

The City of Houston, Harris County Attorney, and Air Alliance Houston argue that the district court abused its discretion by denying civil penalties and injunctive relief despite finding nearly one hundred actionable Clean Air Act violations at Exxon's Baytown complex. The brief contends that the court misapplied the 'seriousness' and 'economic benefit' factors of the Act, ignoring the public health risks of ozone and carcinogens in the Houston-Galveston-Brazoria Ozone Nonattainment Area. It further argues that the court's narrow interpretation of 'repeated' violations allows polluters to evade liability by frequently changing numeric emission limits.

This briefing describes the establishment and outcomes of the State, Local and Tribal Leaders Task Force on Climate Preparedness and Resilience, created by President Obama via Executive Order 13653 on November 1, 2013. The Task Force, comprising 26 governors, mayors, tribal leaders, and county officials, provided the federal government with 35 key recommendations to improve community climate resilience, emphasizing the need for inter-agency coordination and the integration of climate vulnerabilities into all federal policies and investments.

The White House Task Force on Climate Preparedness and Resilience provided 35 recommendations across seven themes to help U.S. communities adapt to climate change. Key priorities include increasing coordination between federal agencies, integrating climate vulnerabilities into all federal policy and funding, and supporting vulnerable populations, including tribal and low-income communities. The federal government has responded with several initiatives, such as the Climate Resilience Toolkit, the National Disaster Resilience Competition, and specific funding requests in the FY 2016 budget for flood, coastal, and drought resilience.

The report identifies a critical gap between climate science outputs and the operational needs of transportation practitioners. It argues that adaptation requires not only improved climate data—such as updated precipitation atlases and sea-level rise projections—but also a deep understanding of local non-climate factors like infrastructure elevation and soil saturation. The document emphasizes the need for a 'central clearinghouse' of information, better 'Climate-to-English' translation of scientific terms, and the integration of climate risk into existing asset management and budgeting processes. It highlights various pilot projects and tools, including the FHWA Risk Assessment Model and Toronto's Climate Change Risk Assessment Tool, as pathways toward increasing the adaptive capacity of transportation systems.
