Outlines the development of the construction sector in the period 1980-2001, e.g. the employment in collective-owned vs. state-owned enterprises, the influx of rural workers, role of labour contractors, and the impact of using pre-fabricated concrete and interior fittings such as doors, flooring...

Impurities such as N2 and O2 can be co-injected with CO2 to cut the overall cost of carbon capture and geological storage by lowering the CO2 capture cost. However, only few field-scale studies have focused on the effect of these impurities, such as N2 and O2, with low solubility and a low...

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...

Japan has started a 5-year national R&D project titled ‘Underground Storage of Carbon Dioxide’ to reduce CO2 emissions into the atmosphere. One of the targets of the project is to select a few preferred storage sites as candidates for large-scale demonstration tests in the next phase, and...

Supercritical CO2 fluid is capable of extracting organic matter from rocks. Although the sealing performance of cap rock is essential for CO2 underground storage, typical cap rock such as shale or mudstone usually contains organic matter. To determine how well cap rocks can seal supercritical...

In this paper, we divide the labor into skilled and unskilled labor to investigate the impact that the heterogeneous labor movement between sectors has on the environment under the international skilled and unskilled labor flows and the price change of the agricultural products. The main...

In this paper, we integrate intra-region labor migration and inter-region labor migration into Harris–Todaro model in the presence of unidirectional trans-boundary pollution. We conduct a simple comparative static analysis of regional economic and environmental effects of the central...
