Primarily, utility gas and kerosene are used as boiler fuel to reduce SOx emissions. In FY2011, NOx emissions were reduced due to the decrease in boiler operating hours at AIST Tsukuba resulting from the 2011 great earthquake.Air Pollution PreventionWater Pollution PreventionWe observe laws, regulations, social norms, code of conduct for researchers, and rules, and thus promote compliance to put the AIST Charter “Full Research in Society, for Society” into practice.

The facilities are inspected on a regular basis and results are recorded.Voluntary inspection of drain pipes following the amendment of the Water Pollution Control Law (prevention of groundwater contamination)●Prior to the amendment of the Water Pollution Control Law, which went into effect on June 1, 2012, in all research bases, we voluntarily inspected outdoor buried drain pipes through which research wastewater flows. The outdoor buried drain pipes were difficult to inspect and therefore were inspected with a fiberscope camera or by filling the pipes with water and checking for leaks. At AIST Hokkaido, AIST Kansai, AIST Chubu, AIST Chugoku, and AIST Kyushu, pipe damage was found and repaired. After the amendment Environmental Compliance58|Environmental ReportEnvironmental Report
