Japan Broadcasting Corporation (NHK) recognizes the conservation of the global environment as a major issue. Through broadcasting we hope to draw public interest and action towards environmental issues. Our business operation is environmentally conscious, introducing new technologies and promoting energy-saving strategies by streamlining our workflow. Here are details on our approach for a greener change.
Tokyo Metropolitan Government's Responsibility to Reduce Emissions of Greenhouse Gases.
NHK Shibuya Broadcasting center and NHK Science and Technical Research Laboratories is working on cutting CO2 emissions by 8% in 5 years from 2010-2014. This first phase for reduction complies with regulations on conservation of the environment stipulated by the Tokyo metropolitan government.
NHK has been introducing solar panels, and new energy-efficient system for air-conditioning and an uninterruptible power source that provides power to broadcast equipment. We also cut power consumption by limiting lighting and elevator use during nighttime and holidays.
NHK's approach to environmental management
NHK cuts electricity consumption by using ultralow-power fluorescent lamps . We have also developed LED studio lights instead of the existing incandescent lamps.
Replacement of Broadcast Vehicles with Greener Vehicles
We started using certified low-emission vehicles and hybrid autos for going on shoots. We also newly developed a small type of "zero emission" live-broadcasting car, which is 100% electrically-powered.
Infrastructure of Photovoltaic System
Solar panels are being introduced at NHK broadcasting halls nationwide. As of April 2011, 27 out of total 54 broadcasting stations are equipped with solar power systems.
Introduction of Hydroelectric System
We have also developed a micro-hydroelectric system using the water fall in ducts for air conditioning. They have been installed at the Tokyo broadcasting center and the Fukuoka broadcasting station.
3Rs during Set-construction
When creating art sets, we take into account the use of environmentally-friendly materials. We also use less materials by designing multiple sets using common parts.
Recycling of Disposed Video Tapes
Disposed videotapes and discs are separated into polycarbonate, polypropylene, polystyrol and acrylic. Those chemical components are recycled to make automobile parts, building materials, stationary and household goods. Teflon-film used in tapes is recycled into work gloves and fishing nets.
