Abstract
Air pollution across the Indo-Gangetic Plains and Himalayan Foothills (IGP-HF) has reached critical levels, threatening health and productivity for nearly one billion people. The impacts are severe: cardiovascular and respiratory diseases have become leading causes of illness and death, average life expectancy in the IGP-HF region is shortened by more than three years, and around one million people die prematurely each year from exposure to polluted air. The associated economic damage is estimated at about 10 percent of regional gross domestic product (GDP) annually, driven by lost labor productivity, higher healthcare costs, and reduced human capital. This Solutions Book, A Breath of Change, sets out a practical roadmap for achieving the region’s shared, intermediate target of reducing annual average PM2.5 concentrations below 35 µg/m³ by 2035 (“35 by 35”), while laying the foundation for progressively cleaner air. Building on the diagnostics and country experiences synthesized in Striving for Clean Air, the solutions book moves from why clean air matters and what drives pollution to how to address air pollution. In other words, how coordinated, feasible, and evidence-based solutions can be implemented at scale. The IGP-HF airshed, an interconnected system spanning 13 jurisdictions across Bangladesh, Bhutan, India, Nepal, and Pakistan, demands solutions that are both multi-sectoral and multi-jurisdictional. Chapter 1 explains why air quality matters in the IGP-HF. Chapter 2 presents sources of air pollution. The Solutions Book highlights a portfolio of interventions in each of the five key pollution emitting sectors: scaling up access to clean cooking fuels and appliances in chapter 3; electrifying and modernizing industrial boilers, furnaces, kilns and thermal power plants in chapter 4; accelerating the transition to electric and efficient vehicles alongside improvements in fuel quality, and strengthening of non-motorized transport in the transport sector in chapter 5; promoting sustainable agricultural crop residue, livestock manure and fertilizer management in chapter 6; and improving waste collection, segregation, and recycling in chapter 7. In parallel, protective sectors, particularly health in chapter 8 and education in chapter 9, play a vital role in helping people cope while air quality remains poor. ross-cutting themes are woven throughout the sectoral chapters, with deeper exploration of governance frameworks, market-based instruments and regional cooperation provided in chapters 10 to 12.

Publication Cleaner Transport Fuels for Cleaner Air in Central Asia and the Caucasus(Washington, DC, 2001-08)Combating pollution needs to be based on standards supported by enforced regulatory, and physical infrastructure, not always in place in countries in transition from central planning to a market economy. Policymakers in the Central Asia and the Caucus region, however, are recognizing the need for such steps against pollution, demonstrated by their commitment to phase out lead from gasoline. To support these efforts, the Bank undertook a regional study on cleaner transport fuels for urban quality improvement in the region, recognizing that fuel quality improvements should be linked to broader air quality management, to ensure cost-effectiveness, and in addressing these issues, it is therefore possible to build on economies of scale, avoid duplications, allow the transfer of experience, and facilitate intra-regional trade in petroleum products. This lead to this study's observations, and recommendations. The establishment of continuous monitoring of the "classical" pollutants, should permit comparison with international standards, by monitoring fine particles, airborne lead, and ground-level ozone. In turn, facilities with diagnostic equipment, and qualified technicians should be available, including vehicle registration systems. It is recommended that gasoline lead should be eliminated by 2005, sulfur in gasoline should be limited by 2015, benzene reductions should be phased out, and instead introduce the acceptable diesel sulfur specifications, and standards as in developed countries. Considerations should include the installation of isomer units; reevaluation on the role of refineries in gasoline production; and, fuel-quality specifications in privatization biding documents, should ensure predictability of regulations.Publication Responding to Climate Change : An Action Plan for the World Bank in Latin America and the Caribbean(World Bank, Washington, DC, 2006-11)Climate change is a very serious environmental challenge that affects prospects for sustainable development. Since the Industrial Revolution, the mean surface temperature of Earth has increased an average of one degree Celsius per century mainly due to the accumulation of greenhouse gases (CHGs) in the atmosphere. Furthermore, most of this change has occurred in the past 30 to 40 years, and the rate of increase is accelerating. A change of this magnitude is unprecedented and will result in significant impacts both at a global scale, and for Latin America and the Caribbean in particular. This paper includes the following headings: impacts are unavoidable; international response; and opportunities to address climate change and local development.Publication Uzbekistan : Overview of Climate Change Activities(Washington, DC, 2013-10)This overview of climate change activities in Uzbekistan is part of a series of country notes for five Central Asian countries that summarize climate portfolio in a number of sectors, namely agriculture, forestry and natural resources, water, health, energy, and transport. The note further provides a brief overview of Uzbekistan's climate context in terms of observed impacts and historical trends as well as climate projections specific to sectors that are considered to be essential to the country's economic development. Finally, the note assesses national policy and institutional context related to climate change as well as suggests potential ways forward that could help Uzbekistan mainstream climate considerations into development activities and planning and create public demand for climate actions.Publication Environment Matters at the World Bank, 2007 Annual Review : Climate Change and Adaptation(Washington, DC, 2007)This edition of environment matters arrives just as the international community embarks on a two-year process to secure a new global framework to limit the amounts of greenhouse gases (GHGs) entering the atmosphere and devise ways to help developing countries adapt to and prepare themselves for the effects of climate change. At the World Bank, the author believe that climate change, and developing countries' adaptation to it, is a critical challenge of our time that must be integrated into core development strategies. Changes in temperatures and weather patterns will affect the frequency and severity of rainfall, droughts, floods, and access to water, flood protection, health, and the use of land. These impacts will not be evenly distributed. The poorest countries and people, those least responsible for climate change and least able to cope with it, will suffer earliest and most due to their geographical location, low incomes, and low institutional capacity, as well as their greater reliance on climate-sensitive sectors like agriculture. This is why building up resilience to increasing climate variability is the most significant climate challenge facing many developing countries. But we believe that adaptation, while necessary in and of itself, can also serve to meet the development objectives of countries. Many appropriate adaptive measures are consistent with good development practice. They can improve the local environment, increase resilience to current and future climate variability and to natural disasters, and ease the dissemination of innovative technologies. They can also reduce resource scarcity within specific social groups or regions, thereby addressing some of the principal causes of social unrest and violent strife. In other words, climate action is development action.Publication Social and Governance Dimensions of Climate Change : Implications for Policy(2009-05-01)This paper addresses two vital concerns in the debate on adaptation to climate change. First, how can countries prepare to manage the impact of climate-change induced natural disasters? Second, how can countries ensure that they have the governmental institutions required to manage the phenomenal challenge of adaptation to climate change? A range of economic and institutional measures are tested for their potential effects on natural disaster resilience and the quality of environmental governance. The findings suggest an important role is played by social and political institutions in determining the ability of countries to adapt to climate change and respond to natural disasters, in particular in the degree to which countries have succeeded in gender empowerment and the development of a robust civil society and nonprofit sector. As the climate change challenge moves from that of "proving the facts" to that of "implementing change," the authors suggest that international policymakers, donors, and activists must increasingly focus on building domestic policy environments that are conducive to the delivery of more effective environmental legislation, for example through implementation of gender quotas and provision of support to civil society groups.

Publication Republic of Congo Country Climate and Development Report - Diversifying Congo's Economy(Washington, DC: World Bank, 2023-10-09)The Republic of Congo (RoC) CCDR is a new World Bank core diagnostic report that integrate climate change and development considerations. It is intended to help the country prioritize the most impactful actions that can boost adaptation and reduce greenhouse gas (GHG) emissions, while delivering on broader development goals. The CCDR builds on data and rigorous research and identify main pathways to reduce climate vulnerabilities and GHG emissions, including the costs and challenges as well as benefits and opportunities from doing so. The report highlights that RoC could reduce poverty in rural areas by 40% and in urban areas by 20% by 2050 by implementing more ambitious reforms to promote economic diversification and climate resilience. It also concludes that business as usual is not an option. Economic losses could reach up to 17% of GDP by 2050 if reforms to diversify the economy and attract more climate investments are not taken. Climate impacts could also increase total health costs from $92 million in 2010 to $260 million by 2050. The report identifies four priorities to promote sustainable growth in the country: (i) stronger and greener infrastructure and services in electricity, transport, water, and sanitation can deliver transformative results; (ii) More climate-ready education, health systems and social services can save lives and bring critical resources to the poorest; (iii) More investments in natural capital including climate smart agriculture and greater forest management along will help create jobs while reducing carbon emissions; (iv) better climate governance to leverage carbon markets. The forest contributes to US$260 million in timber exports and store over 44 billion tons of carbon dioxide equivalent emissions. Protecting and valorizing the forest is critical to turn the country’s natural capital into wealth. The report emphasizes that the private sector has a critical role to play in mobilizing financing for an ambitious set of reforms and investments in the context of tight fiscal space. This will require raising awareness on risks and opportunities from climate change, and innovative solutions and financial sector reforms.Publication Kyrgyz Republic Country Climate and Development Report(Washington, DC: World Bank, 2025-11-03)This Country Climate and Development Report (CCDR) on the Kyrgyz Republic aims to support the country’s development goals amid a changing climate. The CCDR considers two policy scenarios up to 2050: the business-as-usual (BAU) and high-growth scenarios. As it quantifies the likely impacts of climate change on the Kyrgyz economy between now and 2050, the report highlights key government actions to best prepare for and adapt to climate impacts (referred to as “with adaptation” measures), with a particular focus on the time horizon up to 2030. The CCDR also outlines a path to net zero emissions by 2050 (referred to as “with mitigation” measures, “decarbonization,” or, simply, “net zero 2050”), highlighting associated development co-benefits.Publication Senegal Country Climate and Development Report(Washington, DC: World Bank, 2024-11-05)Climate action offers an opportunity to safeguard development gains and accompany the ambitious transformation Senegal is embarking on to achieve its objective of reaching middle income status in the next decade. While the country was among the fastest growing economies in Sub-Saharan Africa (SSA), poverty reduction was slow, vulnerabilities persisted, and inequalities increased. In addition, overall productivity remained low, with lagging structural transformation, high informality, and low job creation. To attain its middle-income goal, Senegal must initiate a series of reforms for a productive, sustainable, and inclusive growth model, with climate considerations at the center given the country’s high vulnerability. Senegal’s high climate vulnerability is caused by the country’s coastal exposure and reliance on natural resources for food, jobs, and growth (partly a consequence of its slow structural transformation). With temperatures soaring, precipitation expected to decrease, and erosion threatening 75 percent of the coastline at term, Senegal’s population and assets are under high risk. The poorest are particularly vulnerable, with 55 percent of total households teetering on the edge of poverty because of recurrent shocks. Without action, annual economic losses could reach 3-4 percent of Gross Domestic Product (GDP) as soon as 2030 and further increase to 9.4 percent by 2050, wiping years of per capita income growth and eroding any potential human capital accumulation. Overall, climate change could push two more million Senegalese in poverty by mid-century. Building resilience and leveraging the low-carbon economy will help Senegal realizing its growth ambitions, contributing to a more productive, sustainable, and inclusive development pathway. The macro-economic analysis for this CCDR finds that adaptation measures in selected sectors could bring GDP gains of about 2 percent by 2030, and between 0.5 and 1 percent afterwards (for climate financing needs of about 0.9 percent of GDP in the period to 2030 and 0.1 percent afterwards). Adaptation could also reduce poverty headcount, with 40 percent less people pushed into poverty by climate change compared to no adaptation action. In addition, emission reductions could reach 20MtCO2e per year over the period to 2050, from interventions in forestry, improved cooking services, urban transport, waste management, and energy production. The energy transition provides an opportunity to meet both development and climate objectives, exceeding NDC targets and putting the country well on track for net zero by 2050, but significant downside risks remain, linked to delays in the deployment and financing availability for renewable generation and domestic gas. Senegal’s formidable renewable energy potential (chiefly around solar) offers the lowest cost generation option to meet rising energy demand while accelerating decarbonization. At term, the country could play a leading role in decarbonizing the region though export opportunities and bolster resilience across the regional grid. In the short term, given constraints to the fast deployment of renewables, the transitional use of domestic gas will help phase out expensive and high-emitting coal and Heavy Fuel Oil (HFO) generation, while balancing the electricity system and lowering the cost of electricity. Climate action will require a financing of US$8.2 billion over 2025-30 (in present value, at 6 percent per year), or 4.5 percent of discounted cumulative GDP over the same period, and US$10.6 billion over 2031-50 (in present value terms), or 2.0 percent of discounted cumulative GDP over the same period. Water security, sustainable (urban) transport, and the energy transition account for the largest share. Importantly, climate action is expected to bring significant benefits over time, beyond climate adaptation and mitigation – including health or jobs, (as in the primary sector, with 155,000 jobs created, of which 80 percent in agriculture). Many benefits could not be properly estimated, implying that the returns from climate action might well be underestimated.Publication Jobs in a Changing Climate: Insights from World Bank Group Country Climate and Development Reports Covering 93 Economies(Washington, DC: World Bank, 2025-11-05)The World Bank Group’s Country Climate and Development Reports (CCDRs) provide a crosscutting look at how countries’ development prospects, and the job opportunities they offer to their people, can be threatened by climate impacts and supported by climate policies. Climate change and policies affect jobs through impacts on productivity, energy and material efficiency, and physical, human, and natural capital. They can also transform employment opportunities, especially through complementary measures that help workers and firms adapt to and benefit from new technologies and production practices. Prepared by the World Bank, the International Finance Corporation (IFC), and the Multilateral Investment Guarantee Agency (MIGA), CCDRs integrate country perspectives, climate science and economic modeling, private sector information, and policy analysis to assess how countries can successfully grow and develop their economies and create jobs despite increasing climate risks and while achieving their climate objectives and commitments. Each CCDR starts from the country’s development priorities, opportunities, and challenges, and is developed in close consultation with governments, businesses, and civil society, ensuring the recommendations reflect national priorities. By combining evidence on adaptation, resilience, and emissions pathways, CCDRs highlight where climate action can reinforce development and job creation, and where targeted policies are needed to manage risks and smooth labor market transitions. Taken together, these elements can help create local jobs, ensure economic transitions are just and inclusive, and equip workers and firms to navigate the disruptions and opportunities of a changing climate and changing technologies.Publication Comoros Country Climate and Development Report(Washington, DC: World Bank, 2025-06-18)The Union of the Comoros (The Comoros) has significant vulnerability to climate change-related risks but has considerable opportunities to strengthen preparedness and resilience against these challenges. According to the Notre Dame Global Adaptation Index, the Comoros is the 29th-most vulnerable country to climate change and the 163rd most ready to adapt (out of 191). The Comoros archipelago is exposed to many natural hazards that adversely affect the country’s natural capital, people, and physical infrastructure. In 2014, the economic cost of climate-related disasters was estimated at 5.7 million dollars annually, equivalent to 9.2 percent of Gross Domestic Product (GDP). Between 2018 and 2023, as many as 11 tropical depressions or cyclones impacted the country, with Cyclone Kenneth causing the greatest damage, equivalent to 14 percent of GDP, resulting in total economic growth falling from 3.6 percent in 2018 to 1.9 percent in 2019. More than 345,000 people (40 percent of the population) were affected by the cyclone, with 185,000 people experiencing severe impacts and 12,000 people displaced. However, there is an opportunity for the country to grow more robust and shock-responsive, and to establish pre-positioned funding mechanisms to enhance future crisis response efforts. For the Comoros, adaptation and climate-resilient development are the key climate change focus areas, with the country projected to face 836 million dollars 2050 in additional costs due to climate-related impacts. Current plans to adapt to the impacts of climate change in the Comoros include efforts to improve water management, strengthen coastal protection, and develop climate-smart agriculture practices. Given the country’s reliance on its natural resource base for economic growth and mobility, protection of these resources from climate change will be essential for promoting resilient growth and development. In addition to growing the adaptive capacity of the country’s natural resource sectors, strategic economic diversification will be important to help minimize future climate impacts, and development activities will need to be undertaken in such a way as to attract low-carbon co-benefits. The Union of the Comoros is committed to addressing climate change through its Nationally Determined Contribution (NDC) and national priorities. The country’s NDC (which was revised in 2021 for a ten-year horizon) sets ambitious targets, with a goal of reducing greenhouse gas emissions by 23 percent by 2030. The country also plans to significantly increase the share of renewable energy in its energy portfolio, reaching 33 MW by 2030. This will not only promote low-carbon development but also reduce the country’s dependency on imported oil and coal, which currently make up 95 percent of the energy mix. Additionally, the Comoros has declared its intention to increase CO2 removals by 47 percent by 2030, compared to BAU.
