The Public Health Effects of Sprawl: A Compelling Case for Addressing Public Health in Transportation and Land Use Policy

The Environmental and Energy Study Institute, in conjunction with the Senate Smart Growth Task Force, held a Congressional briefing to explore the relationship between public health, transportation and land-use. New studies indicate that improvements in land use and community design could help moderate many of the chronic diseases of the 21st century -- high blood pressure, obesity, and asthma -- by providing transportation options that increase physical activity and reduce air pollution. The panel discussed the need to adequately address health considerations in transportation and land-use decisions, and the specific policy measures that could move us toward healthier land-use patterns and healthier communities. The Senate Smart Growth Task Force founded by Senators Carl Levin (D-MI) and Jim Jeffords (I-VT) co-sponsored this briefing. In her opening remarks, Kris Sarri, legislative assistant to Senator Jack Reed (D-RI), a member of the Task Force, invited Senate offices to join the task force. Established in 1999, the Task Force provides Senators with a forum for education and coordination of efforts concerning sustainable growth patterns. The overall goal of the Task Force is to determine and promote ways the federal government can help states and localities to address their own growth management issues. On the date of the briefing 20 Senators or 1/5th of the Senate were listed as members of the Task Force

Bus Rapid Transit Systems: Expanding Transit Investment Alternatives at the Federal Level

Policymakers are looking at Bus Rapid Transit as a complement to current mass transit investment options, including light- and heavy-rail. The Transportation Equity Act for the 21st Century (TEA- 21), which provides six-year funding for highway and transit programs, including Major Capital Investment "New Starts" Projects, expired on September 30th. An extension was approved through February 29th. New Starts Projects are defined under current legislation as fixed-guideway systems (like rail systems) that significantly restructure land use and congestion patterns in an urban area. As policymakers look for ways to invest in BRT, the Department of Transportation is encouraging BRT eligibility under the New Starts Program. The proposal included in the "Safe, Accountable, Flexible and Efficient Transportation Equity Act of 2003" (SAFETEA), the policy recommendation for TEA-21 reauthorization put forth by the Bush Administration, provides funding under the New Starts Program to "non-fixed guideway" systems. The Congress will consider this as it debates SAFETEA through 2003 and 2004

Agriculture Policy Is Health Policy.

The Farm Bill is meant to supplement and secure farm incomes, ensure a stable food supply, and support the American farm economy. Over time, however, it has evolved into a system that creates substantial health impacts, both directly and indirectly. By generating more profit for food producers and less for family farmers; by effectively subsidizing the production of lower-cost fats, sugars, and oils that intensify the health-destroying obesity epidemic; by amplifying environmentally destructive agricultural practices that impact air, water, and other resources, the Farm Bill influences the health of Americans more than is immediately apparent. In this article, we outline three major public health issues influenced by American farm policy. These are (1) rising obesity; (2) food safety; and (3) environmental health impacts, especially exposure to toxic substances and pesticides

The global burden of transportation tailpipe emissions on air pollution-related mortality in 2010 and 2015

Emissions from the transportation sector are a major contributor to ambient air pollution, the leading environmental health risk factor globally. This study aims to quantify the contribution of tailpipe emissions from global transportation, disaggregated by four sub-sectors, to the global disease burden associated with ambient fine particulate matter (PM2.5) and ground-level ozone in 2010 and 2015. We use the GEOS-Chem global chemical transport model to simulate transportation-attributable PM2.5 and ozone concentrations, combined with epidemiological health impact assessment methods consistent with the Global Burden of Disease 2017 study to estimate the associated burden of disease. We estimate that emissions from the transportation sector were associated with 361 000 (95% CI, 258 000&ndash;462 000) PM2.5 and ozone deaths in 2010 and 385 000 (95% CI, 274 000&ndash;493 000) in 2015. These results translate into 11.7% of total global ambient PM2.5 and ozone deaths in 2010 and 11.4% in 2015. Together, PM2.5 and ozone concentrations from transportation tailpipe emissions resulted in an estimated 7.8 million years of life lost and approximately $1 trillion (2015 US$) in health damages globally in 2015. Among transportation sub-sectors, on-road diesels contributed most to the health burden from transportation tailpipe emissions in nearly all trade blocs, for both PM2.5 and ozone, though other sub-sectors also contributed substantially (particularly on-road non-diesel vehicles for ozone mortality, and shipping and non-road mobile sources for PM2.5 mortality). These results indicate that despite recent adoption of more stringent vehicle emission regulations in many countries, the transportation sector remains a major contributor to the air pollution disease burden globally. Future work may explore the degree to which currently adopted policies, as well as expected growth in the transportation sector in India, Africa, and other rapidly developing locations, will influence future transportation-attributable public health burdens. </div

Impacts and mitigation of excess diesel-related NOx emissions in 11 major vehicle markets

Vehicle emissions contribute to fine particulate matter (PM 2.5) and tropospheric ozone air pollution, affecting human health, crop yields and climate worldwide. On-road diesel vehicles produce approximately 20 per cent of global anthropogenic emissions of nitrogen oxides (NO x), which are key PM 2.5 and ozone precursors. Regulated NO x emission limits in leading markets have been progressively tightened, but current diesel vehicles emit far more NO x under real-world operating conditions than during laboratory certification testing. Here we show that across 11 markets, representing approximately 80 per cent of global diesel vehicle sales, nearly one-third of on-road heavy-duty diesel vehicle emissions and over half of on-road light-duty diesel vehicle emissions are in excess of certification limits. These excess emissions (totalling 4.6 million tons) are associated with about 38,000 PM 2.5 - and ozone-related premature deaths globally in 2015, including about 10 per cent of all ozone-related premature deaths in the 28 European Union member states. Heavy-duty vehicles are the dominant contributor to excess diesel NO x emissions and associated health impacts in almost all regions. Adopting and enforcing next-generation standards (more stringent than Euro 6/VI) could nearly eliminate real-world diesel-related NO x emissions in these markets, avoiding approximately 174,000 global PM 2.5 - and ozone-related premature deaths in 2040. Most of these benefits can be achieved by implementing Euro VI standards where they have not yet been adopted for heavy-duty vehicles
