In this paper, a regionally disaggregated global energy model treating energy and CO<Subscript>2</Subscript> transportation in detail is used to examine a cost-effective pattern for their interregional transportation over the 21st century under the CO<Subscript>2</Subscript> stabilization target of 550ppm. Also, we assess future...</subscript></subscript>

The purpose of this study was to assess comprehensively the technological measures for limiting CO<Subscript>2</Subscript> concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system and then to sketch concrete scenarios for the desirable future...</subscript>

The objective of this study was to evaluate the various technological options for the future development of China’s electric power sector taking into consideration its environmental impact. A baseline case, four sulfur control cases, and two carbon control cases were simulated in the...

It has become important to address the question of which energy related infrastructure, such as transcontinental natural gas pipelines, should be constructed in Asia. In addition, one needs to ask how energy demand should be satisfied securely and economically, as well as environmentally...

Cost effectiveness of CO2 sequestration, especially into aquifers, strongly depends on the sequestration capacities and the routes to connect CO2 sequestration sites and recovery sites. This site dependency of CO2 sequestration makes its evaluation difficult. In order to evaluate the cost...

R&D (research and development) processes of CO2 capture technologies having different levels of energy efficiency are evaluated through GERT (Graphical Evaluation and Review Technique) analyses. Five types of the technologies are targeted for evaluation: chemical absorption, physical adsorption,...

Fresh water is one of the most important resources required for human existence, and ensuring its stable supply is a critical issue for sustainable development. The effects of a general set of agriculture and water management adaptations on the size of the world’s water-stressed population...

If dangerous climatic change is to be avoided, all countries will need to contribute to reductions in greenhouse gas emissions on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities. This article discusses the gap between the...
