Implementation of Life Cycle Assessments

In fiscal 2006, the Sumitomo Forestry Group carried out life cycle assessments (LCA)*1 at each of its businesses with the help of Tokyo University of Agriculture and Technology (TUAT) to ascertain the environmental impact of its products. Since then, the Group has introduced carbon footprint (CFP)*2 labels for individual products and carried out life cycle assessments of detached housing among other initiatives.

For example, Group company PT. Rimba Partikel Indonesia (RPI) conducts LCAs of particle board (PB) that it manufactures and sells, covering the production and transportation of the raw materials through to manufacturing of the products. The company also voluntarily displays CFP labels on PB products based on LCA results.

In fiscal 2015, the Group conducted assessments on construction of and waste from the 26 year-old Company-build home and 300 year-old home renovations. The comparison of LCA results between renovation including energy-efficiency reform and rebuilding found that renovation practices are able to achieve both greater convenience and reduction of environmental burden.

RPI started displaying CFP labels on PB products in 2009 (first time for Indonesian companies in the timber products market)

  • *1 A method of evaluating the overall environmental impact of a product throughout its life cycle (all stages, including raw material procurement, manufacturing, transportation, sale, use, reuse and disposal).
  • *2 A measure indicating the amount of greenhouse gases emitted over the entire life cycle of a product or service converted into CO2.

Review of Methodology of carbon fixation through Harvested Wood Products (HWP)

Sumitomo Forestry is working together with International Tropical Timber Organization (ITTO) in the ITTO-led HWP research program for consolidation of the HWP carbon fixation methodology. HWP stands for Harvested Wood Products. In international negotiations concerning climate change, efficacy of carbon fixation by timber products have been discussed. The 17th United Nations Climate Change Conference (COP17) decided that change of carbon storage in home-building timber can be reported as either a country’s greenhouse gas absorbance or emissions during the second commitment period. This demonstrates that international authorities validated the effect of increased carbon storage by timber products towards mitigation of the global temperature rise.
