  The authors discuss results of research with interviews or questionnaires on business needs, focused on data of down-scaling climate variation prediction and past meteorological re-analysis, having undertook Data Integration and Analysis System Program (DIAS-P). The results show that major needs are related to support of using these data. Anticipated user supports are allocation of staff familiar with business deals, the clarification and proxy of contracts and rights, and the access to and trial use of samples. Depending on capability of developing applications, required user supports are classified. Companies insufficient for application development needs collaborative research, while think tanks and IT companies needs concierges under non-disclosure agreement.

  For the High Bio Diesel (HiBD) process, a new biodiesel synthesis method, Life Cycle Inventory (LCI) analysis was conducted based on the actual performance data of the demonstration plant and the scenario data assuming a commercial plant. When comparing energy consumption, fossil resource consumption, and GHG emissions for HiBD and FAME, various reduction effects of HiBD and FAME toward diesel fuel were comparable. Regarding the raw material of HiBD, it was confirmed that various reductions were larger in the order of centrifuged oil, waste cooking oil, and crude palm oil (CPO).
