We have been developing a policy support tool, AIM/impact[policy], for use in the integrated assessment of global warming control targets including the stabilization of greenhouse gas concentrations, economically efficient emissions paths to realizing these targets, and consequent impacts and...

Countries participating in international environmental negotiations widely ignore secondary or ancillary benefits, which are not derived from a policy’s main aim. If in political reasoning, the urgency of the consideration of secondary benefits subsequently gets a higher weight, the necessity...

Japan’s long-term CO<Subscript>2</Subscript> emission reduction scenarios are assessed with a computable general equilibrium model with recursive dynamics, which was modified in order to assess the effects of renewable energy supply. The period of assessment is from 2000 to 2050 and the increase of gross domestic...</subscript>

Several countries are striving to ensure adequate long-run disposal space for low-level radioactive waste (LLRW). In the United States, the Low-Level Radioactive Waste Policy Act of 1980 and its 1985 amendments comprise a menu of incentives and penalties designed to motivate the construction of...

Using a bottom-up model, the effectiveness of carbon tax policy and a policy mix related to a carbon tax in Japan are assessed to reduce CO<Subscript>2</Subscript> emissions to the targeted level in the first commitment period of the Kyoto Protocol. In this simulation, only existing technologies and practical new...</subscript>

This article assesses emissions scenarios in the literature, originally documented in the scenario database that was developed more than 7 years ago. The original scenario assessment and literature review has been used, among other things, as the basis for the quantification of the...

With the rises in population, number of vehicles, energy consumption, and economic activity in the Seoul metropolitan area, it is difficult for existing environmental policies and measures to mitigate air pollution. To respond to such challenges, the Ministry of the Environment of the Republic...

The objectives of this study were to carry out a review of mitigation scenarios that have emerged since the Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report (TAR), to update the current Emissions Scenarios Database with these scenarios, and to analyze emissions and...

Considering the latest arguments on global warming, CO<Subscript>2</Subscript> emissions reduction by not only developed countries but also by developing countries is becoming a pivotal issue. Although the worldwide uniform-rate carbon tax (UCT) is thought to be a cost-effective method to reduce CO<Subscript>2</Subscript> emissions, it...</subscript></subscript>
