    One of the most important environment problems negatively affecting human life is desertification. Desertification of the Huang River Basin, for example, has been progressing and seriously, having an adverse impact on the environment. One fundamental solution for desertification is planting trees. This must be done systematically, however, by using a macro engineering approach. This approach, especially as it concerns the macro management of tree planting, treats the forest as a social system—that is, social forestry—where the government plays an important role in addressing the problem of desertification. In this connection, host governments can use ODA assistance from Japan to achieve their project targets for preventing desertification. Consequently, a macro engineering approach has the potential to resolve this serious environment problem.

    The amount of CO2 emission about information delivery was compared between the Internet information-delivery type newspaper and usual printed paper-delivery type newspaper by LCA method. Net-delivery newspapers can reduce CO2 emission if the amount of information printed out was less than 17 sheets of A4 size OA paper (4.8 pages of usual newspaper). Without printing, the CO2 emission of net-delivery newspapers are smaller than that of printed-paper delivery newspaper when browsing hours on desktop PC and notebook PC are less than 1.3 hours/day and 1.7 hours/day, respectively.

    In this paper, suppose that the consumption of crude oil will be decreased in order to reduce the carbon dioxide emission, and the carbon tax is therefore enforced as a means to reduce the consumption of that. Authors supposed that from the viewpoint of the price elasticity, "characteristics" of crude oil as consumption goods are discussed, and calculated the rate of carbon tax from the value of each price elasticities of demand on the goods. Furthermore, we assumed that we impose the rate of carbon tax on the imported crude oil. In addition, by using the input-output table in 1995 the price repercussion effect was calculated. In conclusion, if we use the tax based on the value of price elasticity of demand, the repercussion effect in price changes on each industry in Japan is not so large.
