Material Issue 2: Promote the reduction of the environmental impact of our business activities

Basic policy

With the impact of climate change becoming increasingly problematic on a global scale, companies are being asked to reduce greenhouse gas emissions and implement energy saving initiatives. In Japan, the Basic Energy Plan of July 2018 set out a policy goal of having “more than 50% of new custom-built detached houses built by housing manufacturers and others to be ZEH (Net Zero Energy Houses) by 2020, and to have all newly built houses be ZEH on average by 2030.” In addition, as part of the roadmap to popularize ZEH and achieve this average by 2030, major companies involved in the construction of detached houses are being asked to popularize ZEH on their own through the supply of large volumes of ZEH.

Sumitomo Forestry Group has operations in the housing business and in the manufacture of wood panels and building materials. In consideration of the environmental impact of these operations, the Group fully recognizes the importance of reducing greenhouse emissions and taking other measures to combat climate change through the promotion of strict energy-saving activities, renewable energy use and other efforts. With a mid- to long-term perspective of the future, in 2018, we established greenhouse gas emission reduction goals for 2030.

In our housing business, we have set a fiscal 2020 target for an 80% ratio of ZEH. Starting in April 2017, we have promoted the popularization of ZEH by adding reinforced insulation for the building and aperture area and solar power energy generation systems as standard specifications for newly built houses. In addition, to reduce environmental burden and more effectively utilize natural resources, we are promoting the reduction, reuse and recycling of industrial waste.

With the establishment of new KPIs, we are also working to further revitalize our activities and reduce risk.
