Safety assessments for chemical substances
The NTT Science and Core Technology Laboratory Group has created an environmental management system to conduct environmental conservation activities. The Group has obtained approval as an Environmental Management Office under the local Kanagawa Prefectural Ordinance on the Protection of Local Living Environments, and conducts annual chemical emissions hazard assessments based on Kanagawa Prefecture's approved assessment methods. Following the same result in fiscal 2008, the fiscal 2009 assessment showed the impacts on the ecosystem and human health of the Laboratory Group's activities to be low and requiring no immediate actions.

Assessing the environmental impacts of research activities
Environmental impacts of the NTT Science and Core Technology Laboratory Group stem from chemical use, wastewater, gas emissions, material waste, as well as the power consumed by air conditioning for research clean rooms.
In addition to constant monitoring of water quality, the Group conducts periodical surveys of the atmosphere, rain and ground water, odors, soil, as well as noise and vibration in order to track and assess its environmental impacts. It has also established voluntary standards that are stricter than legally mandated pollution standards.
A fiscal 2009 atmospheric environmental study found no atmospheric pollutants that exceeded these strict voluntary standards.
