Abstract

The paper aims to provide the basis for an estimation equation and will focus on the relation between transport emissions and air quality in an urban environment. This is directly related to the fact that most health impacts are related to local air quality levels. The aim of the paper is to create an understanding of the factors that play a role in the causal relation between transport emissions and health effects and provides approximations from existing studies that can be used to assess these health impacts and related costs. The paper focuses on the translation of air pollution levels into health impacts and health costs. The overall structure of the paper follows the two key steps and elaborates on the inherent challenges: (1) identify and measure the health effects of air pollution, and (2) to estimate the costs of the health effects. The paper is divided into four chapters: chapter one is introduction- outlining the goals and background to the project; chapter two gives impacts of air pollution from transport on health; chapter three presents valuation of health impacts- reviews the literature on how to value the impacts on health associated with air pollution; and chapter four gives guidelines for calculating the health effects of air pollution from traffic.

Abstract

China is experiencing rapid and large scale urbanization, and the resulting local and global urban environmental challenges are unprecedented. The Chinese Government has fully recognized these challenges and is aiming to promote more sustainable urbanization in line with the objectives of the eleventh five year plan, which calls for 'building a resource-conserving and environmentally friendly society'. Various initiatives are being pursued to support this objective, both at the national and local levels. At the local level, cities have responded by developing 'eco-cities', which aim to promote a more sustainable urbanization model. More than one hundred eco-city initiatives have been launched in recent years. One such initiative is the Sino-Singapore Tianjin eco-city. The purpose of this report is to review the Sino-Singapore Tianjin Eco-City (SSTEC) project from a comprehensive perspective with a view to achieving the following principal objectives: (i) create a detailed knowledge base on the project; (ii) provide policy advice on key issues, especially those related to the Global Environment Facility (GEF) project; (iii) estimate SSTEC's Greenhouse Gas (GHG) emission reduction potential; and (iv) contextualize the project among the broader ecological urban development initiatives in China. Broadening the World Bank's engagement beyond the GEF was assessed as important given the project's complexity, and its potential to shed light on China's sustainable urban development challenge

Abstract

Thailand needs to avoid the high-carbon growth path of many developed countries and, instead, take a low-carbon growth path. A green low-carbon growth path is in Thailand's own interest as it can simultaneously tackle local environmental degradation, global climate change, and energy security challenges. It can also position Thailand as a regional leader in green, sustainable growth. Green low-carbon growth in Thailand could focus on the following four pillars: 1) maintaining rapid economic growth while adjusting the country's economic structure toward a less energy, and carbon-intensive economy; 2) achieving greater urbanization while shifting toward green livable low-carbon cities; 3) meeting the huge thirst for energy while transforming the energy sector toward one of high energy efficiency and widespread diffusion of low-carbon technologies; and 4) improving quality of life while shifting toward a resource-efficient and sustainable lifestyle.

Abstract

The primary objective of the Southern Gobi Regional Environmental Assessment (REA) is to provide guidance for sustainable management of environmental resources in the future development of the Southern Gobi Region (SGR), development that will be led by rapid expansion of mining. The REA defines two development scenarios-a base-case and a high case-and explores their direct and indirect impacts on the natural environment, taking into account the opportunities, constraints, and vulnerabilities of the Gobi natural systems; the individual and cumulative direct environmental impacts and potential indirect impacts of the planned development; and, at a general level, the institutional capacity to manage the impacts. The REA target audience includes government officials at central, regional, and local levels; private sector investors and the consultants who are engaged for project design and environmental impact assessment; development finance organizations; and Mongolian civil society. This report was discussed in draft form at stakeholder workshops held in Ulaanbaatar and Dalanzagdad in April 2009 and has been revised to reflect comments received. Thanks are due to all those who joined those discussions. The report draws on information from workshops held in Mongolia, in May, September, and October 2008, and a field mission to the Southern Gobi Region in November 2008. Other information was obtained from various mining companies in Mongolia including Ivanhoe mines Mongolia, Inc., and its consultant Eco Trade; Rio Tinto; Energy Resources LLC; and South Gobi Sands.

Abstract

Comparisons of measured and model-predicted atmospheric copper concentrations show a severe underestimation of the observed concentrations by the models. This underestimation may be (partly) due to underestimated emissions of copper to air. Since the phase out of asbestos brake lining material, the composition of brake lining material has changed and may contain up to ∼15% copper. This makes brake wear from vehicles potentially an important source of atmospheric (particulate) copper concentrations. In this paper, we reassess the copper emissions due to exhaust emissions and brake wear from road transport. Overall, our reassessments result in an estimate of total copper emission to air in UNECE-Europe of 4.0-5.5 ktonnes yr-1, which is substantially higher than the previous estimate of 2.8 ktonnes yr-1. Copper concentrations over Europe are calculated with the LOTOS-EUROS model using the revised emission data as model input. The results show that the revised emission estimates are a major step towards gap closure of predicted versus observed copper concentrations in ambient air. Brake wear emissions may be responsible for 50-75% of the total copper emissions to air for most of Western Europe. The hypothesis that road transport is an important source of copper emissions is tested and confirmed by (1) reviewing available literature data of chemically speciated PM data from road tunnel studies and (2) the gradient observed in copper concentrations from ambient PM monitoring going from rural sites to street stations. The literature review and observational data suggest that the majority of the emitted PM10 brake wear particles is in the PM2.5-10 size range. The results of this study indicate that modification of brake lining composition is an important mitigation option to reduce copper exposure of the population in Western Europe. © 2007 Elsevier Ltd.
