"Ecosystem services" has become a catch-phrase for the complex connections between the natural environment and human well-being. This paper considers the impact of changes in the supply of ecosystem services, and programs to increase their supply, on near-term growth of gross domestic product. It focuses on the relationship between locally generated versus transboundary services and growth in developing countries, where the highest rates of ecosystem degradation tend to be found. There is a common perception that there is a tradeoff between environmental protection and economic growth, especially in the near term. This perception can make policymakers reluctant to support environmental protection. Where the environment is a source of economically important services, then environmental protection may stimulate growth of gross domestic product instead of reducing it. The paper considers evidence on the economic value of regulating services; the degree to which ecosystems actually supply some of the services they are commonly assumed to supply; and the near-term growth implications of restoring ecosystems, and reducing their loss.
This paper reviews the challenges and opportunities raised by international trade for developing countries considering a green growth strategy. A key concern is the effect of environmental policies on international competitiveness. For production-generated pollution, there is evidence that stringent environmental policy reduces some indicators of competitiveness, but the effect is small in most sectors. However, tightening up environmental standards is unlikely to reduce international competitiveness when pollution is generated by consumption. And where depletion of natural capital is a threat, effective environmental policy is an important component of a policy aimed at developing long-run international competitiveness. The effects of trade on environmental policy, the interaction between trade and technology transfer, and the interaction between trade and transboundary environmental problems are also reviewed. An emerging issue is the potential use of border taxes to curtail carbon leakage. The paper discusses some of the possible responses by developing countries.
Transportation is vital to economic and social development, but at the same time generates undesired consequences on local, regional, and global scales. One of the largest challenges is the mitigation of energy-related carbon dioxide emissions, to which this sector already contributes one-quarter globally and one-third in the United States. Technology measures are the prerequisite for drastically mitigating energy use and all emission species, but they are not sufficient. The resulting need for complementing technology measures with behavioral change policies contrasts sharply with the analyses carried out by virtually all energy / economy / environment (E3) models, given their focus on pure technology-based solutions. This paper addresses the challenges for E3 models to simulate behavioral changes in transportation. A survey of 13 major models concludes that especially hybrid energy models would already be capable of simulating some behavioral change policies, most notably the imposition of the full marginal societal costs of transportation.
This paper reviews dynamic general equilibrium models in order to collect insights on the interaction between economic growth and environmental issues. The authors discuss the Ramsey model and extend it for natural resource inputs and pollution, as well as for endogenous technical change. Green growth becomes within reach if there is good substitution, a clean backstop technology, a small share of natural resources in gross domestic product, and/or green directed technical change.
One of the key environmental problems facing India is that of particle pollution from the combustion of fossil fuels. This has serious health consequences and with the rapid growth in the economy these impacts are increasing. At the same time, economic growth is an imperative and policymakers are concerned about the possibility that pollution reduction measures could reduce growth significantly.
India's Economic Growth and Environmental Sustainability: What are the tradeoffs? addresses the tradeoffs involved in controlling local pollutants such as particles. Using an established Computable General Equilibrium model, it evaluates the impacts of a tax on coal or on emissions of particles such that these instruments result in emission levels that are respectively 10 percent and 30 percent lower than they otherwise would be in 2030.
This tool kit assists staff and consultants of the Asian Development Bank (ADB) in conceptualizing and designing gender-responsive projects in the energy sector. It guides users in key questions to be asked and data to be collected during project preparation. It also offers a menu of entry points in designing project outputs, activities, inputs, indicators, and targets that integrate key gender issues identified during the gender analysis. The tool kit is broken down into key subsectors of ADB's energy sector investments - transmission and distribution, rural electrification, energy efficiency, and renewable energy. Case studies from ADB energy projects have been included to illustrate good practices in mainstreaming gender in energy sector.
