Book excerpt: The objectives of this study were to: (1) evaluate a new low-cost approach for measuring on-road tailpipe emissions of highway vehicles; (2) investigate factors that affect the amount and variability of on-road emissions, using statistical methods; and (3) devise and demonstrate methods for designing and conducting observational experiments that realistically evaluate pollution prevention strategies for on-road vehicles. Portable instruments were used for measuring carbon monoxide (CO), nitric oxide (NO), and hydrocarbon (HC) emissions and vehicle activity (e.g., vehicle speed, engine parameters) on a second-by-second basis. Data collection, quality assurance, reduction, and analysis protocols were developed. Field data collection occurred in a pilot and an evaluation phase. In total, over 1,200 one-way trips were made with more than 20 vehicles, 4,000 vehicle-miles traveled, 160 hours of data, and 10 drivers. The pilot study was used to identify key factors influencing on-road emissions and as input to the design of the evaluation study. In the evaluation study, data were collected intensively with a small number of vehicles on two corridors before and after signal timing and coordination changes were implemented. For the first corridor, changes in signal timing and coordination did not result in a significant change in traffic flow or emissions. However, substantial reductions in emissions were estimated for uncongested versus congested traffic flow when comparing travel in the same direction at different times of day. For the second corridor, there were significant improvements in traffic flow and some reduction in emissions for three of the four time period and travel direction combinations evaluated. The impact of signal timing and coordination changes with respect to non-priority movements involving cross-streets was evaluated. For the first corridor, there was no statistically significant observed change in emissions for non-priority movements. For the second corridor, there typically was a decrease in average speed and an increase in emissions for non-priority movements; however, many of the observed changes were not statistically significant. The study also demonstrated other analysis methods, including: (a) macro-scale analysis of trip average emissions and traffic parameters; (b) micro-scale analysis of second-by-second emissions and vehicle operation; (c) mesoscale analysis of modal emission rates; and (d) spatial analysis of emissions at specific locations along the corridors. Both statistical and theoretical-based approaches were evaluated. The implications of the study results for pollution prevention strategies are discussed. Conclusions are presented regarding instrumentation, protocols, analysis techniques, and case study-specific findings. Recommendations are given regarding future applications of on-board measurements.

Download or read book Air Protection in the European Union Member States written by Magdalena Tomala and published by Taylor & Francis. This book was released on 2024-09-10 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Member states of the European Union often label themselves as the world’s top Green Leaders. Air Protection in the European Union Member States examines the EU members' air protection policies by taking into consideration wider political, social, and economic perspectives. The book is divided into four chapters, each focusing on different aspects of the European Union's environmental policies and the member states' air protection efforts: "Green and Smart – The Development of the European Union’s Environmental Policies", "Ever Cleaner Union and the Air Protection Concept", "Trends of Air Pollution in the European Union – Comparative Perspective", and "In-Depth Case Studies". These chapters provide a comparative approach to emerging emission trends within the European Union, paying particular attention to key events spanning 2020–2023, such as the implementation of the Green Deal, the reinterpretation of the meaning of public health caused by the COVID-19 pandemic, and the strategic withdrawal from hydrocarbons accelerated by the outbreak of war in Ukraine. Throughout the book, three main categories of states are characterized: leaders, second-raters, and laggards. Air Protection in the European Union Member States presents a combination of general discussions, legislative analyses, comparative studies, and detailed case studies, demonstrating the origin, development, and trends in air protection policies within the European Union. This uniquely interdisciplinary book will be a vital guide for students, researchers, and teachers in the fields of global studies, international relations, and political and economic science.

Download or read book Aviation and the Environment NextGen and Research and Development are Keys to Reducing Emissions and Their Impact on Health and Climate written by Gerald L. Dillingham and published by DIANE Publishing. This book was released on 2008-10 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collaboration between the fed. gov¿t. and the aviation industry has led to reductions in aviation emissions (AE), but growing air traffic has partially offset these reductions. Various fed. agencies are working to increase the efficiency, safety, and capacity of the nat. airspace system and at the same time reduce AE, in part, by transforming the current air traffic control system to the Next Generation Air Transp. System (NextGen). This effort involves new technologies and air traffic procedures that can reduce AE and incorporates R&D on emissions-reduction technologies. This testimony addresses: (1) the scope and nature of AE; (2) the status of selected key fed. efforts to reduce AE; and (3) next steps and challenges in reducing AE. Illustrations.
Download or read book Climate Change and the World Bank Group written by World Bank and published by World Bank Publications. This book was released on 2011-01-26 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study from the Independent Evaluation Group draws lessons for development and climate change mitigation from the World Bank Group's far-reaching portfolio of projects in energy, forestry, transport, coal power, and technology transfer. Reviewing what has worked, what hasn't, and why, the evaluation's key findings include: Energy efficiency can offer countries direct economic returns that dwarf those of most other development projects, while also reducing greenhouse gas emissions. Tropical forest protected areas, on average, significantly reduce tropical deforestation, preserving carbon and biodiversity. Deforestation rates are lower in areas that allowed sustainable use by local populations than in strictly protected areas. Deforestation rates were lowest of all in indigenous forest areas. For renewable energy projects, long-duration loans have been important in making projects financially viable.. But at prevailing carbon prices, carbon offset sales had little impact on most renewable energy projects rate of returns, and did not address investors need for up-front capital. Technology transfer broadly understood to include diffusion of technical and financial innovations related to low-carbon development has worked well when the logic of piloting and demonstration is well thought out, and when grants are used to mitigate the risk of pioneering efforts.

Book excerpt: "Both the public and private sectors are grappling with decisions regarding policies that will lead to reductions in greenhouse gas (GHG) emissions. Moving Cooler analyzes and assesses the effectiveness and costs of almost 50 transportation strategies for reducing GHG emissions, as well as evaluates combinations of those strategies. The findings of this study can help decision makers coordinate and shape effective approaches to reducing GHG emissions at all levels - national, regional, and local - while also meeting broader transportation objectives." --Book Jacket.
