According to a report by the World Bank published in April 2018, air pollution in Tehran incurs annual loss of billions of dollars and over 4,000 premature deaths from exposure to fine particles ambient concentrations. Particulate matter (PM), one of the primary pollutants from diesel exhaust, is associated with many different types of respiratory and cardiovascular effects, and premature mortality. The main objective of this study is to evaluate the cost effectiveness of retrofitting existing city diesel bus fleet in Tehran with best available Diesel particulate filters (DPFs) available in the market. The report provides an updated assessment on the diesel retrofit solutions for an ageing diesel city bus fleet in Tehran based on publicly available information. The economic benefits of DPF installed in buses are evaluated with standard techniques of environmental economics, and technological assumptions about how much PM emissions can be avoided and control costs. The report highlights a number of national, regional and local examples of effective emission control program that exhibit best practices from around the world. Also, it presents important features and global experiences of successful retrofit program on heavy-duty diesel vehicles (HDDVs), including benefit-cost analysis from several case studies to help Tehran city leadership in taking informed economic and policy decisions. Finally, it recommends a set of critical actions to the government both at the national and local level for implementation of an effective emission control programs.

The Western Balkans is home to the most polluting power plants in Europe, and its transport and energy infrastructure require updates. Not surprisingly, countries such as Kosovo, are suffering from severe urban air pollution and traffic congestion as a result of high dependence on fossil fuels in the energy matrix, inefficient transport system and aging vehicle fleets. These substantially harm public health, productivity and efficiency in urban mobility. Kosovo is implementing the EU enacted Stabilization Tracking Mechanism programme, aiming to gradually integrate its national policies on legal, economic and social matters with the EU. On 6 February 2018, the European Commission published its expansion plan to cover up to six Western Balkan countries including Kosovo with potential accession as members of the EU after 2025. This is relevant for vehicle emissions as it entails implementation of EU vehicle emission and fuel standards. The development objective of this project is to support the government of Kosovo and City of Pristina to develop strategies to reduce emissions and pollutions from transport perspective, such as modernization and better management of public and private vehicle fleets, and to scope for components and activities to be considered as part of potential Develop Policy Financing or Investment Project Financing by the World Bank The layout of the report includes the following sections: Chapter second realizes a rapid assessment of vehicle pollution for Kosovo including vehicle emission trends. Chapter third list in a summarized manner major instruments to reduce transportation emissions. Based on the problem and solution description policies are selected which are assessed in further detail to curb vehicle emissions in Kosovo. These policies or interventions were selected based on on-going plans and activities and interest from the Government. They include usage of low-emission buses (chapter fourth), fiscal instruments to promote low-emitting vehicles (chapter fifth) and implementation of in-service vehicle emission testing.

Myanmar is rich in natural resources and is a global biodiversity hotspot. Myanmar's forests and fishing industry are two significant contributors to the economy, and yet these sectors are also potentially under threat from over exploitation and mismanagement. The management of solid waste, air pollution, and the use of plastics provides another growing challenge. In addition, the role of government and other stakeholders in the management of these sectors and issues is central to whether the government will succeed in reversing the current trends and be able to find a long-term sustainable solution to the problem. This report explores the issues and challenges faced and the legal and institutional context. Through a lens of poverty reduction, social inclusion and participation, and economic growth, the report tells a story of an urgent need for institutional support and reform, improvements in the enforcement against illegal extraction of resources, behavior change in all relevant stakeholders, institutional capacity building, increased funding, and improvements in data collection and analysis. If these recommendations are acted on, then Myanmar can reverse the negative trends and lead its environment on a path toward a more sustainable future.

Uses of main primary energy resources, such as coal, oil, and solid biomass, are directly linked with adverse impacts on human health. Air pollution emitted from various activities in the energy supply chains is the main risk factor to human health, along with accidental and occupational risk exposures. Estimates of premature deaths are over four million per year for ambient air pollution (2015) and household or indoor air pollution (2012). More than 80 percent of the mortality from ambient air pollution emitted from the energy supply chains occurs in developing countries. The impact of household air pollution, mainly from traditional biomass used for cooking and space heating, disproportionately falls on women and children under age five years. Acute respiratory infections, mainly caused by household air pollution, are one of the largest categories of deaths (64 percent) of children under age five years in developing countries. These statistics indicate the deep nexus between the energy supply chain and human health. Yet, the negative implications for human health from energy use often receive inadequate consideration. It is critically important to take account of these human health impacts in developing energy supply plans and energy policies in developing countries.

Outdoor air pollution accounts for an estimated 4.2 million deaths worldwide, the majority of which are caused by exposure to fine particulate matter (or PM2.5) air pollution. Most of these deaths occur in low- and middle-income countries (LMICs). Reducing PM2.5 air pollution is thus crucial for improving public-health outcomes in those countries. Measuring and reducing the health impacts of PM2.5 is especially challenging in many LMICs because ground-level air-quality monitoring networks are typically nonexistent. Where they are in place, they are often not properly operated and maintained and are thus unreliable. Limited local expertise in air-quality measurement presents additional challenges. These shortcomings can undermine a country's ability to design and implement effective policies to improve outdoor air quality. Satellite technology has been used successfully for measuring air quality in high-income countries where operation of ground-level air-quality monitoring networks is well established. However, this publication investigates the performance of satellites in LMICs for predicting outdoor concentrations of PM2.5, based on case studies in nine cities in different regions representing a range of environmental conditions (including mountainous, dusty, and coastal). The report finds that the satellite-derived estimates of PM2.5 in LMICs are associated with very large uncertainty, ranging from 21 percent to 85 percent depending on the model used for translating satellite measurements of aerosol optical depth-the parameter measured by satellites-to surface-level outdoor PM2.5 concentrations. This report shows that satellites are unreliable for estimating ambient concentrations of PM2.5 in LMICs. Furthermore, satellite-derived measurements cannot replace properly operated and maintained ground-level monitoring networks for measuring the concentrations of PM2.5 that human beings are typically exposed to daily. Thus, it is important that LMICs strengthen support for the establishment of ground-level monitoring networks to measure air pollutants, notably PM2.5, that cause mortality in Sub-Saharan Africa and other regions with LMICs.
