Abstract
This paper studies the conditions under which debt securities that make the cost of debt contingent on the issuer's carbon emissions, similar to sustainability-linked loans and bonds, can be equivalent to a carbon tax. The paper proposes a model in which standard and environmentally-oriented agents can adopt polluting and nonpolluting technologies, with the latter being less profitable than the former. A carbon tax can correct the laissez-faire economy in which the polluting technology is adopted by standard agents, but requires sufficient political support. Carbon-contingent securities provide an alternative price incentive for standard agents to adopt the nonpolluting technology, but require sufficient funds to fully substitute the regulatory tool. Absent political support for the tax, carbon-contingent securities can only improve welfare, but the same is not true when some support for a carbon tax exists. Understanding the conditions under which the regulatory and capital market tools are substitutes or complements within one economy is an important steppingstone in thinking about carbon pricing globally. It sheds light, for instance, on how developed economies can deploy finance to curb carbon emissions in developing economies where support for a carbon tax does not exist.

Publication Tax Policy to Reduce Carbon Emissions in South Africa(2009-05-01)Noting that South Africa may be one of the few African countries that could contribute to mitigating climate change, the authors explore the impact of a carbon tax relative to alternative energy taxes on economic welfare. Using a disaggregate general-equilibrium model of the South African economy, they capture the structural characteristics of the energy sector, linking a supply mix that is heavily skewed toward coal to energy use by different sectors and hence their carbon content. The authors consider a "pure" carbon tax as well as various proxy taxes such as those on energy or energy-intensive sectors like transport and basic metals, all of which achieve the same level of carbon reduction. In general, the more targeted the tax to carbon emissions, the better the welfare results. If a carbon tax is feasible, it will have the least marginal cost of abatement by a substantial amount when compared to alternative tax instruments. If a carbon tax is not feasible, a sales tax on energy inputs is the next best option. Moreover, labor market distortions such as labor market segmentation or unemployment will likely dominate the welfare and equity implications of a carbon tax for South Africa. This being the case, if South Africa were able to remove some of the distortions in the labor market, the cost of carbon taxation would be negligible. In short, the discussion of carbon taxation in South Africa can focus on considerations other than the economic welfare costs, which are likely to be quite low.Publication Reducing Carbon Dioxide Emissions through Joint Implementation of Projects(World Bank, Washington, DC, 2000-06)Efficient reduction of carbon dioxide emissions requires coordination of international efforts. Approaches proposed include carbon taxes, emission quotas, and jointly implemented energy projects. To reduce emissions efficiently, requires equalizing the marginal costs of reduction between countries. The apparently large differentials between the costs of reducing emissions in industrial and developing countries, implies a great potential for lowering the costs of reducing emissions by focusing on projects in developing countries. Most proposals for joint implementation of energy projects emphasize installing more technically efficient capital equipment, to allow reductions in energy use for any given mix of input, and output. But such increases in efficiency are likely to have potentially important second-round impacts: 1) Lowering the relative effective price of specific energy products. 2) Lowering the price of energy relative to other inputs. 3) Lowering the price of energy-intensive products relative to other products. The author explores the consequences of these second-round impacts, and suggests ways to deal with them in practical joint-implementation projects. For example, the direct impact of reducing the effective price of a fuel is to increase consumption of that fuel. Generally, substitution effects also reduce the use of other fuels, and the emissions generated from them. If the fuel whose efficiency is being improved, is already the least emission-intensive, the combined impact of these price changes is less likely to be favorable, and may even increase emissions. In the example the author uses, increase in coal use efficiency was completely ineffective in reducing emissions, because it resulted in emission-intensive coal being substituted for less polluting oil and gas.Publication Assessing Low-Carbon Development in Nigeria : An Analysis of Four Sectors(Washington, DC: World Bank, 2013-01-01)The Federal Government of Nigeria (FGN) and the World Bank have agreed to carry out a Climate Change Assessment (CCA) within the framework of the Bank's Country Partnership Strategy (CPS) for Nigeria (2010-13). The CCA includes an analysis of options for low-carbon development in selected sectors, including power, oil and gas, transport, and agriculture. The goal of the low-carbon analysis is to define likely trends in carbon emissions up to 2035, based on government sector development plans, and to identify opportunities for achieving equivalent development objectives with a reduced carbon footprint. This study comprises the following components: (i) development of a reference scenario of greenhouse gas (GHG) net emissions for the agriculture sector, consistent with vision 20: 2020 and other government plans; (ii) identification of opportunities for reduced net emissions- reduced emissions and or enhanced carbon sequestration- while achieving the same development objectives as in the reference scenario; and (iii) economic assessment of low-carbon options in order to help the Nigerian government to prioritize policy options. The study evaluates costs and benefits in a partial equilibrium setting, with no attempt to capture the indirect, general equilibrium effects of adopting low-carbon technologies or management practices. The results of this analysis (the first of its kind in Nigeria) should be considered as a first approximation of the potential for low-carbon development in the Nigerian agriculture sector. The study aims at providing policy makers with an order-of-magnitude estimate of mitigation potential, and an understanding of the value of dedicating further efforts (including through specific projects) at pursuing low-carbon development in agriculture, but is not meant to inform the design of specific, project-level interventions.Publication Low-Carbon Development : Opportunities for Nigeria(Washington, DC: World Bank, 2013-05-29)The Federal Government of Nigeria (FGN) has formulated an ambitious strategy, known as Vision 20: 2020, which aims to make Nigeria the world s 20th largest economy by 2020. This book argues that there are many ways that Nigeria can achieve the Vision 20: 2020 development objectives for 2020 and beyond, but with up to 32 percent lower carbon emissions. A lower carbon path offers not only the global benefits of reducing contributions to climate change, but also net economic benefits to Nigeria, estimated at about 2 percent of gross domestic product (GDP). The FGN and the World Bank agreed, as part of the Country Partnership Strategy (CPS) 2010-13, to conduct an analysis of the implications of climate change for Nigeria's development agenda. The current volume focuses on low-carbon development. Building on the work under way on Nigeria's nationally appropriate mitigation actions, the authors evaluate opportunities to pursue national development priorities using technologies and interventions that reduce emissions of greenhouse gases (GHGs), referred to here as low-carbon options. The document is structured as follows: chapter one is introduction; chapter two provides essential background on the country and the economic sectors. Chapter three describes the analytical approach, providing a summary of how the scenarios were developed, methods of analysis, models, and the data and general assumptions used. Chapters four-seven present the analysis and results for each sector: agriculture and land use, oil and gas, power, and transport, respectively. Each chapter provides an introduction to the sector and the approach, findings, and recommendations for options and actions for low-carbon development. Chapter eight summarizes the key findings across sectors. It describes the main scenarios that were modeled across all sectors and their implications for GHG emissions and the economy. It provides general recommendations on how Nigeria can reconcile national growth objectives with low-carbon development using a cross-sector perspective.Publication Carbon Markets, Institutions, Policies, and Research(World Bank, Washington, DC, 2008-10)The scale of investment needed to slow greenhouse gas emissions is larger than governments can manage through transfers. Therefore, climate change policies rely heavily on markets and private capital. This is especially true in the case of the Kyoto Protocol with its provisions for trade and investment in joint projects. This paper describes institutions and policies important for new carbon markets and explains their origins. Research efforts that explore conceptual aspects of current policy are surveyed along with empirical studies that make predictions about how carbon markets will work and perform. The authors summarize early investment and price outcomes from newly formed markets and point out areas where markets have preformed as predicted and areas where markets remain incomplete. Overall the scale of carbon-market investment planned exceeds earlier expectations, but the geographic dispersion of investment is uneven and important opportunities for abatement remain untapped in some sectors, indicating a need for additional research on how investment markets work. How best to promote the development and deployment of new technologies is another promising area for study identified in the paper.

Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.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 World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.Publication Doing Business 2014 : Understanding Regulations for Small and Medium-Size Enterprises(Washington, DC: World Bank Group, 2013-10-28)Eleventh in a series of annual reports comparing business regulation in 185 economies, Doing Business 2014 measures regulations affecting 11 areas of everyday business activity: Starting a business, Dealing with construction permits, Getting electricity, Registering property, Getting credit, Protecting investors, Paying taxes, Trading across borders, Enforcing contracts, Closing a business, Employing workers. The report updates all indicators as of June 1, 2013, ranks economies on their overall “ease of doing business”, and analyzes reforms to business regulation – identifying which economies are strengthening their business environment the most. The Doing Business reports illustrate how reforms in business regulations are being used to analyze economic outcomes for domestic entrepreneurs and for the wider economy. Doing Business is a flagship product by the World Bank and IFC that garners worldwide attention on regulatory barriers to entrepreneurship. More than 60 economies use the Doing Business indicators to shape reform agendas and monitor improvements on the ground. In addition, the Doing Business data has generated over 870 articles in peer-reviewed academic journals since its inception.Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.
