1. Economic evaluation of energy technology
Carrying out economical assesment for energy supplying technologies, including standalone systems such as fossil fuel power plants, biomass, as well as residuals, CCS (carbon capture and storage) and so on. In order to evaluate cost of electricity as well as reducing environmental pollutant emissions such as CO2.
2. Energy system analysis and materials resourcing
In section 1 (Economic evaluation of energy technology), energy technology is solely assesed, however, resources for energy and materials as well as energy technologies are correlated, since the resources are defined as flows and stocks within the socio-economic activities (called energy systems). Hence, system analysis of demand/supply is needed, not only for the resources but also for forecasting technologies that are carried out in Japan, Asia, and around the world within the time horizon: 2030, 2050, and 2100.
3. Environmental impacts assessment
In previous sections, (marginal) cost of reducing emission polluatants, such as CO2, SOx, NOx are evaluated. In this section, economical impacts by pollutant emissions are assessed, based on the lifecycle impact assesment model (LCIA) as well as integrated assessment modeling (IAM). Marginal willingness to pay (MWTP) can be estimated using social survey.
4. Assessing sustainability by their indicators
From previous section, capitals in physical, natural, and environment can be quantitatively assessed. In this section, various sustainability indicators, especially based on environmental and resource economics, are analyzed based on tthese three capitals plus human capital. The indicator, named "inclusive wealth" captures sustainability by changes in value of the four capitals. Other non-economic various indicators such as resources productivity, eco-efficiency, and human appropriated photosythetic net primary productivity (HANPP) of are also investigated..
