Abstract
South Asia is home to 9 of the world's 10 cities with the worst air pollution. Concentrations of fine particulate matter (PM2.5) in some of the region's most densely populated and poor areas are up to 20 times higher than what the World Health Organization considers healthy (5 micrograms per cubic meter). This pollution causes an estimated 2 million premature deaths in the region each year and results in significant economic costs. Controlling air pollution is difficult without a better understanding of the activities that cause emissions of particulate matter. Air pollution travels long distances in South Asia and gets trapped in large 'airsheds' that are shaped by climatology and geography. 'Striving for Clean Air' identifies six major airsheds in the region and analyzes four scenarios for reducing air pollution with varying degrees of policy implementation and cooperation among countries. The analysis shows that cooperation between different jurisdictions within an airshed is crucial, and a schematic road map with three phases is proposed. The phases in the road map may overlap when the rate of progress differs, depending on local circumstances. Phase 1 would improve monitoring and institutions; Phase 2 would introduce additional and joint targets for cost-effective abatement; and Phase 3 would mainstream air quality in the economy.

Publication Introducing Energy-efficient Clean Technologies in the Brick Sector of Bangladesh(World Bank, 2011-06-30)This study's objectives are: (i) to present the pros and cons of existing and alternative brick technologies in Bangladesh with specific focus on pollution and energy efficiency; (ii) to estimate the private and social benefits of these technologies (iii) to summarize China's experience in the development of the brick industry, as the world leader brick producer and (iv) to provide concrete recommendations for adopting cleaner technologies in Bangladesh. The study focuses on the brick cluster located in northern Dhaka, which comprises 530 Fixed Chimney Kiln (FCKs) that produce 2.1 billion bricks annually (14 percent of the country's brick production). As the brick sector is a prominent contributor to air pollution in Dhaka, it is important to distinguish its contribution to the city's air pollution from other sources, including transport and other industries. Because of limited data availability, the analysis relies on the most realistic assumptions drawn from monitored data in Bangladesh or neighboring countries (i.e., Nepal and India). As a result, the estimated net returns for each technology are orders of magnitude rather than precise estimates. This report analysis the brick sector in Bangladesh and assesses the feasibility of cleaner alternative technologies.Publication Clean Stove Initiative Forum Proceedings : Beijing, China, April 26-29, 2014(Washington, DC, 2014-11)The objectives of the second EAP CSI Regional Forum are twofold. The first is to share the progress, findings, and challenges of implementing the initiative s second phase. The second is to promote South-South collaboration, learning, and knowledge-sharing, with a focus on China s experiences. The forum is being held in Beijing on April 28, 2014, as part of a four-day event (April 26 29, 2014). A two-day, pre-forum event held April 26 27 focuses on participation in the 8th China Clean Stoves Expo in Langfang, Hebei province. Post-forum, South-South knowledge-exchange activities, scheduled for April 29, feature a meeting with officials of China s Rural Energy and Environment Agency (REEA) on South- South collaboration, tour of the stove-testing center at China Agriculture University in Beijing, and field visits with local stove manufacturers in Gaobeidian, Hebei province. The forum is co-organized by the China Alliance for Clean Stoves (CACS) and the REEA, Ministry of Agriculture, with funding support provided by the Australian government s DFAT, through the World Bank s EAAIG, and ASTAE.Publication Clean Air and Cool Planet, Volume II(Washington, DC, 2022-07)The report synthesizes key findings and recommendations of a study carried out under the World Bank’s Advisory Services and Analytics Program, ‘Central Asia: Climate and Environment Program,’ which aims to strengthen the capacity of Central Asian countries to achieve sustainable and resilient economic growth. It builds on a previous World Bank report, which provided the first national-level approximation of primary sources of air pollution in Kazakhstan. This city-level study highlights how potential synergies between air quality improvement and greenhouse gas reduction measures can be enhanced in a cost-effective manner. To identify and maximize these synergies and assess the measures’ cost-effectiveness at the city level, the study developed two new extensions to the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model—GAINS-City and GAINS-Policy and applied them in Almaty and Nur-Sultan, two major cities in Kazakhstan, for the first time. The report delivers evidence of the main causes of premature deaths from air pollution in Almaty and Nur-Sultan and offers guidance on cost-effective solutions to prevent them while making the cities better prepared for a low-carbon future. It provides high-level roadmaps for the cities' integrated air quality management and climate change mitigation to maximize synergies and manage tradeoffs. It proposes sequencing of actions until 2030 to save lives from poor air quality while facilitating long-term phase out of fossil fuels. Moreover, the report analyzes the need for policy reforms to incentivize implementation of cost-effective integrated measures by private economic actors. The report recognizes that reprioritizing policy actions slightly to maximize climate benefits may require some additional air quality management actions to address the unacceptably high burden that exposure to PM2.5 currently places on public health.Publication Securing Durable Development in Afghanistan : Policy Notes for the Government(Washington, DC, 2010-04)The government of Afghanistan has an opportunity in the coming months to turn the country around. It is now opportune to improve security, governance, and development. Unprecedented international military support, political attention and aid are available to Afghanistan. The government is inheriting years of good economic performance, notable progress on social outcomes, and continuing strong support from the international community. Gross domestic product (GDP) has grown at an average of 12 percent in the last five years with moderate inflation and a stable Afghani. The National Solidarity Program is spurring community-driven rural development in nearly all districts of the country and the large opium economy is in retreat. Significant progress has been achieved in basic education and health. Gender indicators are improving. The government and its development partners have an obligation to seize this opportunity for all Afghans. All donors made an explicit commitment at the London Conference in January 2010 to progressively cede leadership to the Afghan people. The donors agreed to route half of their development aid through the national budget from the current one-fifth in the next two years, as local capacity to execute development programs improves. Further, donors aim to work together to improve aid effectiveness by better alignment with Afghan priorities, minimize opportunities for corruption and improve aid predictability. This overview summarizes the view of the World Bank on priority development issues and policy actions. It is intended to be a useful reference for the government as it prepares for the Kabul conference. The issues and policy options proposed are consistent with the ands and the Bank's interim strategy note of May 2009. It synthesizes the key findings and analyses of the detailed policy notes which draw upon the World Bank's past and ongoing work in Afghanistan, as well as wider experiences, including those from other countries experiencing conflict.Publication Clean Air and Cool Planet(World Bank, Washington, DC, 2021-12)This report provides the first national-level approximation of priority sources and actions to address air pollution while maximizing synergies with climate mitigation and managing trade-off challenges. The study uses mean population exposure as the best approximation of air quality impact currently available. It is a scoping exercise to determine the least-cost priority measures to improve air quality and identify potential key synergies or trade-offs with climate change mitigation that can be managed through coherent application of air and climate protection policies.

Publication State and Trends of Carbon Pricing 2024(Washington, DC: World Bank, 2024-05-21)This report provides an up-to-date overview of existing and emerging carbon pricing instruments around the world, including international, national, and subnational initiatives. It also investigates trends surrounding the development and implementation of carbon pricing instruments and some of the drivers seen over the past year. Specifically, this report covers carbon taxes, emissions trading systems (ETSs), and crediting mechanisms. Key topics covered in the 2024 report include uptake of ETSs and carbon taxes in low- and middle- income economies, sectoral coverage of ETSs and carbon taxes, and the use of crediting mechanisms as part of the policy mix.Publication Women, Business and the Law 2023(Washington, DC: World Bank, 2023-03-02)“Women, Business and the Law 2023” is the ninth in a series of annual studies measuring the laws and regulations that affect women’s economic opportunity in 190 economies. The project presents eight indicators structured around women’s interactions with the law as they move through their lives and careers: Mobility, Workplace, Pay, Marriage, Parenthood, Entrepreneurship, Assets, and Pension. The 2023 edition identifies barriers to women’s economic participation and encourages reform of discriminatory laws. This year, the study also includes research, a literature review, and analysis of 53 years of reforms for women’s rights. Examining the economic decisions that women make throughout their working lives as well as tracking regulatory changes from 1970 to today, the study makes an important contribution to research and policy discussions about the state of women’s economic opportunities. By presenting powerful examples of change and highlighting the gaps still remaining, “Women, Business and the Law 2023” is a vital tool in ensuring economic empowerment for all. Data in “Women, Business and the Law 2023” are current as of October 1, 2022.Publication Global Economic Prospects, June 2024(Washington, DC: World Bank, 2024-06-11)After several years of negative shocks, global growth is expected to hold steady in 2024 and then edge up in the next couple of years, in part aided by cautious monetary policy easing as inflation gradually declines. However, economic prospects are envisaged to remain tepid, especially in the most vulnerable countries. Risks to the outlook, while more balanced, are still tilted to the downside, including the possibility of escalating geopolitical tensions, further trade fragmentation, and higher-for-longer interest rates. Natural disasters related to climate change could also hinder activity. Subdued growth prospects across many emerging market and developing economies and continued risks underscore the need for decisive policy action at the global and national levels. Global Economic Prospects is a World Bank Group Flagship Report that examines global economic developments and prospects, with a special focus on emerging market and developing economies, on a semiannual basis (in January and June). Each edition includes analytical pieces on topical policy challenges faced by these economies.Publication Falling Long-Term Growth Prospects(World Bank : Washington, DC, 2024-02-01)A structural growth slowdown is underway across the world: at current trends, the global potential growth rate is expected to fall to a three-decade low over the remainder of the 2020s. Nearly all the forces that have powered growth and prosperity since the early 1990s have weakened, not only because of a series of shocks to the global economy over the past three years. A persistent and broad-based decline in long-term growth prospects imperils the ability of emerging market and developing economies to combat poverty, tackle climate change, and meet other key development objectives. These challenges call for an ambitious policy response at the national and global levels. This book presents the first detailed analysis of the growth slowdown and a rich menu of policy options to deliver better growth outcomes.Publication Commodity Markets Outlook, April 2024(Washington, DC: World Bank, 2024-04-25)The conflict in the Middle East has been exerting upward pressures on prices of key commodities, notably oil and gold. High commodity prices, despite relatively subdued global GDP growth, suggest some countervailing forces offsetting tepid demand, such as heightened geopolitical strains and increasing metals-intensive investments in the energy transition. Commodity prices are forecast to soften marginally in 2024 and 2025 but remain substantially above pre-pandemic levels. Unlike most other prices, crude oil prices are expected to increase in 2024, mainly reflecting geopolitical tensions. The key risk to commodity price projections relates to the possibility of a broadening of the Middle East conflict, which could lead to significantly higher oil prices, thus reigniting global inflationary pressures. Meanwhile, food insecurity worsened markedly last year, reflecting elevated food prices and armed conflicts around the world. Should such conflicts worsen, global hunger could rise substantially. Heightened uncertainty around the commodity price outlook underscores the importance of forecast accuracy. A Special Focus section evaluates the performance of five approaches used to forecast prices of three commodities—aluminum, copper, and oil. It concludes that there is no “one-approach-beats-all.” Macroeconometric models tend to be more accurate at longer horizons, mainly due to their ability to account for the impact of structural changes. It is, however, critical to incorporate judgment and information that cannot be accounted for by statistical approaches. This highlights the importance of employing a wide range of approaches when forecasting commodity prices.
