We consider three climate policy scenarios that reach radiative forcing levels in 2100 of three Representative Concentration Pathways (RCPs). These targets are achieved by introducing a global uniform tax on all GHG emissions in the Integrated Assessment Model WITCH, assuming both full as well as limited technological flexibility. The resulting consumption patterns of fossil fuels are used to estimate the physical impacts and the economic benefits of pollution reductions on human health and on key assets by implementing the most advanced version of the ExternE methodology with its Impact Pathway Analysis. We find that the mitigation scenario compatible with +2°C reduces total pollution costs in Europe by 76%. Discounted ancillary benefits are more than €2.5 trillion between 2015 and 2100. The monetary value of reduced pollution is equal to €22 per abated ton of CO2 in Europe. Less strict climate policy scenarios generate overall smaller, but still considerable, local benefits (14 € or 18 € per abated ton of CO2). Without discounting, the ancillary benefits are in a range of €36 to €50 per ton of CO2 abated. Cumulative ancillary benefits exceed the cumulative additional cost of electricity generation in Europe. Each European country alone would be better off if the mitigation policy was implemented, although the local benefits in absolute terms vary significantly across the countries. We can identify the relative losers and winners of ancillary benefits in Europe. In particular, we find that large European countries contribute to as much as they benefit from ancillary benefits. The scenarios with limited technology flexibility do deliver results that are similar to the full technology flexibility scenario.

An increasing number of environmental regulators in developed and developing countries have embarked on programmes for the promotion of environmentally sound and sustainable development strategies. Air pollution is among the most important environmental issues that need to be managed since it reflects directly and indirectly on the different aspects of human life. This paper presents an assessment of the evolution of air pollution control philosophies at the global level, and it describes advantages and disadvantages of alternate environmental strategies that can be considered in the development of an integrated and comprehensive plan for air quality management at the local level, with Lebanon as a case study of a typical developing country. The proposed strategy considers short-, medium-and long-term schemes that make use of regulatory and market-based instruments, such as pollution charges, and market creation and usage. The short-term scheme identifies serious polluters and improves environmental performance by adopting and enforcing updated environmental standards. Economic incentive concepts constitute the principal philosophy for medium-term application of a comprehensive environmental strategy, mostly applicable at the level of the transportation and energy sectors. Long-term strategies, targeting the industrial sector, aim at achieving a flexible free market in which polluters would compete on the basis of market forces and governmental incentives to attain better environmental performance and increase potential cost savings.

SummaryThe benefits of climate policy normally consist exclusively of the reduced impacts of climate change, i.e., the policy's primary aim. Our analysis of benefits of climate policy suggests, however, that researchers and policymakers should also take account of ancillary benefits, e.g., in the shape of improved air quality induced by climate protection measures. A consideration of both, primary and ancillary benefits, has a positive influence on global climate protection efforts, e.g., because the regional impact of ancillary effects attenuates easy-riding motives of countries with respect to their provision of climate protection. In this article, we analyze the nature of ancillary benefits, present an overview of European assessment studies and explain possible methods to estimate ancillary benefits. Main differences between primary and ancillary benefits are pointed out. Furthermore, we stress the major influences of ancillary benefits on climate policy. Finally, we present one of the first models integrating primary and ancillary benefits. By this model quantitative results are calculated with respect to ancillary benefits in the UK considering different green-house gas (GHG) control levels. It is observed that the ancillary benefits could cover about 4 percent of the full GHG reduction cost.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
