1. Stock Estimation and Future Scenario Analysis based on Chemical Substance and Product Classification

We evaluate the effectiveness of countermeasure options for unusual situations, taking into account the cause, scale, and nature of the disaster/incident and the nature of the air, water, and soil affected by the event, based on risk theory.  Subsequently, we develop management guidelines to implement the countermeasure options in terms of regulation and self-management.

Risk assessments should be performed even when there is insufficient knowledge of what is required. We have developed an evaluation method for performing risk assessments with limited information, and determine additional data collection requirements for specific variables, to enable practical risk assessment.

Also, risk assessment is a dynamic process that must be updated as the knowledge is available. We have been developing an evaluation method to support risk management measures based on the amount of knowledge accumulated and changes in circumstances. As an example, we successfully proposed prototype models for flame retardants.

 To establish a low-carbon society (60-80% reduction in greenhouse gas emissions by 2050), it is essential to analyze the structure of countervailing risks and to propose management principles based on the clarification of the trade-off structure, while  aiming at the reduction of greenhouse gas emission risks. We focus on the low carbon policy of the automotive industry and analyze the risk trade-off between the spread of next-generation vehicles and the use of biofuels.

3. Analysis of behavior change in lifestyle and estimation of induced effects.

Maintaining the convenience and environmental quality of life requires risk management in the industrial environmental system, which is  consumers and the manufacturing industry are part of. We design an Environmental Accounting for Households that encourages an understanding of the two sides of the relationship between consumer convenience and dependence on the environment. Research is being conducted on the Environmental Accounting for Householdsto determine the potential contribution of people’s behavior change to the reduction of environmental impacts (and whether there is room for it).

4. Development of a policy support model for chemical management.

AIST-ADMER, METI-LIS, and AIST-SHANEL, developed by the National Institute of Advanced Industrial Science and Technology, are examples of exposure analysis models for environmental emission systems that are used in the industrial sector. In addition to these models, by developing an exposure analysis model in an indoor working environment, it is possible to comprehensively understand the exposure route of chemical substances for the industry.

We are engaged in research such as the systematization of the European working environment exposure assessment model, Advanced REACH Tool, to draw relevant lessons for application in the Japanese safety management of work environment industry.

5. Material generation and dispersion models, meta-analysis, Bayesian estimation method, impact analysis of occupational exposure control measures

Japan’s chemical management from a macroscopic perspective is based on the Chemical Substances Control Law (*1) and the Chemical Substances Control Law (*2). We analyze the cost-effectiveness in reducing health and ecological risks for chemical substance management measures implemented at the government level.

*1 The control level of a substance is classified by screening and classifying it in terms of toxicity and exposure classes and specifying the control level.

*2 Obligation to report chemical substance emissions, as represented by the PRTR system

6. Planning and evaluation of renewal plans for low-carbon and resource-recycling infrastructures through cross-cutting cooperation.

We conduct flow stock analysis to support the replacement of venous social capital such as sewage treatment plants and waste incineration facilities with a decentralized energy supply center and a center of resource metabolism within the city and between cities and rural areas.

The evaluation targets include coordinated measures for sewage treatment and incineration facilities based on the mixed anaerobic digestion of kitchen waste and sewage sludge, and the impact of water and rainwater harvesting equipment on energy production at sewage treatment facilities. The analysis focuses on these cross-sectoral and coordinated plans.

7. Building a Prototype Model for Urban Risk Governance Management.

To solve the global environmental risk of global warming over a very long period, a considerable amount of money is being spent on this issue. Measures against chemical substances given to long-term exposure (over a person’s lifetime) and water quality management policies aimed at protecting ecosystems, such as the OECD’s recommendation to Japan, are being promoted. Meanwhile, cities are being asked to respond to the crises that may occur in the near future at the local level, such as vulnerabilities emerging fromcomplex disasters. If these responses are carried out under under individual optimal solutions on different evaluation axes , there is a concern that this process may result in a burden on future generations and other regions. We aim to construct a theory and develop methods to manage and govern these different types of risks in an integrated framework, and to demonstrate the applicability of these methods through case studies.
