“The rapid assimilation and analysis of a range of information sources, including life cycle based studies, market, and scientific research, expert opinion and stakeholder concerns. The outputs from this analysis can then be used to identify and prioritise potential actions around the most significant economic, environmental and social sustainability impacts or benefits associated with a specific country, city, industry sector, organization, product portfolio, product category or individual product or service. Hotspots analysis is often used as a pre-cursor to developing more detailed or granular sustainability information”

In 2014, the UNEP (United Nations Environment Program) / SETAC (Environmental Toxic Chemicals Society) life cycle initiative focused on hot spot analysis that extracts important elements from the life cycle and started to develop analysis methods.

Project

Expected effect

Hotspot analysis of automobiles and paper was conducted using Japanese version environmental hotspot analysis tool

6.References5.Conclusion

Establishment of a Common Framework of Environmental Assessment Considering Product Life Cycle and Promotion of Green Purchasing with the Application of Scientific based Approach

What is Hotspots Analysis?

Task1: Development of Environmental Hotspot Analysis Method (Inventory / Impact Assessment Method)

Task 2: Implementation of environmental hotspot analysis (100 products)

- By using this evaluation it became the evaluation base of ecotype label certification.· Companies can use environmental hotspot analysis tools and results to make environmental information disclosure at a high speed.· It is expected to be used as one index of quantitative environmental information disclosure of ESG (environment, society, government) investment.

Based on the inventory database IDEA (Inventory Database for Lifecycle Analysis)we are updating statistical data and extending it including overseas data.

We conduct the necessary investigation to develop the database according to the account system of the Waste Input Output (WIO) table (disposal stage).

We summarize the relationship with LIME (Life cycle Impact assessment based on endpoint modeling), summarize it for each 17 impact areas, developing the characterization coefficient, and evaluate environmental impact.

Integration result of automobile (by impact area)

Climate change and resource consumption at the use stage became hot spots.

Burning gasoline while driving affects climate change. Consumption of petroleum products affects resource

consumption.

Forest resources at raw material stage and air pollution at the manufacturing stage became hot spots

Forest resources are caused by timber consumption of paper raw materials.

Air pollution affects the ship when transporting wood.
