SAI’s role in promoting national sustainable development The 6th Seminar on Environmental Auditing （October 2016） Board of Audit of Japan
Contents １．Background information ２．Audit case: demanded measures for improvement of the road reconstruction projects with environmentally-conscious as well as economical design by promoting the use of recycled crushed stone, etc. ３．Experience and Challenges ４．SAI’s role in promoting the national sustainable development
1. Background Information Japan’s Proactive involvement in SDGs • Launch of SDGs Promotion Headquarters on 20th May to facilitate close collaboration among relevant ministries • “SDGs Implementation Guidelines” will be formed through interviews with ministries, agencies and stakeholders • Implementation status will be followed up The audits by the Board cover most of the areas in 17 SDGs
2.Audit cases – Outline of audit cases and the relevant SDGs ・Recycle Act was enacted in 1991 for purpose of ensuring the effective utilization of recyclable resources as well as contributing to waste reduction and environmental preservation. ・ Recycled crushed stone was inexpensive compared with virgin crushed stone The Board focused on the necessity of efforts to promote the use of recycled stone. The Board has repeatedly reported on this matter for more than 15 years. - FY1996: Demanded measures to the Ministry of Construction - FY2001: Demanded measures to Japan Railway Construction Public Corporation - FY2006 and 2008: Demanded measures to MLIT - FY2012: Demanded measures to MAFF (for forest roads) - FY2013: Demanded measures to MAFF (for a bedding materials for pipelines)
2. Audit Case: Outline of Audit case in 1996 Use of recycled crushed stone for road reconstruction projects (Ministry of Construction) (FY1996 Audit Report) The subjects: 2807 cases of road improvement/paving work implemented in FY1995/ 1996 in 11 prefectures with national subsidies from Ministry of Construction. Audit result: The use rate of recycled crushed stone in the work was considerably low even though the work was carried out in the areas where it was possible to use recycled crushed stone and there was no particular problem where the recycled crushed stone was used for other work conducted by Ministry of Construction. → The Board concluded that in principle, it was necessary to use recycled crushed stone which was available at a lower price and strive to make economical estimates and beneficial use of materials.
2. Audit Case: Outline of Audit case in 1996 Actions taken by auditee: • The 11 prefectures decided to disseminate, and provide guidance on, the active use of recycled crushed stone to the municipalities under the jurisdiction of the prefectures by revising their guidelines for the use of such stone within the period from April to December 1997. • In November 1997, in an attempt to once again thoroughly disseminate the utilization of recycled crushed stone, the Ministry of Construction notified prefectures, etc., to make efforts to encourage each Operating Body implementing public construction work to actively use the stone.
2. Audit Case: Audit cases from FY 2001 to 2013 Summary of Audit cases FY 2001, 2008 and 2012
3. Experience and Challenges • The Board came to report the audit findings as a result of its audit on whether it was actually possible to use recycled crushed stone, from a wide range of aspects including quality, distribution quantity and price. • The Board pointed out that the scope of use of not only recycled crushed stone but also reconditioned sand should be extended from their use as a subbase course material in road improvement projects for general roads, to their use as a base course material for construction roads and an upper-base course material for gravel forest roads etc. • The Board’s audits focusing on the effective utilization of environmentally-conscious resources and on economical designing can be considered to contribute to such expansion to a certain extent.

4. SAI’s role in promoting the national sustainable development • Audits not only on the projects for the national sustainable development, but also on other programs and projects can contribute to the national sustainable development. • SAI can support the government’s policies and the accomplishment of the SDGs by focusing on policies and plans relating to the national sustainable development, and performing audits with the objective of effectiveness etc.
