| NEC Evaluates Impact of PCs on Environment
February 20, 1998 (TOKYO) -- NEC Corp. and Shizuoka NEC, a
personal computer production arm of NEC, evaluated the effects of
PCs on the environment, company officials said.
|The quantitative evaluation covered the entire life cycle of PCs,
ranging from production and utilization to disposal.
The two firms claim that the quantitative evaluation, based on
ISO14040 specifications regarding the environment, is the first
such study of its kind in the world. On the basis of this
evaluation, the companies plan to develop PCs that take into
account environmental factors.
In making the evaluation, they adopted a method called the Life
Cycle Assessment based on ISO14040, which was established in June
Chosen for the testing was the space-saving ValueStar NX VS26D/CX
PC, which was evaluated in terms of global warming, acid rain and
The ValueStar model's influence on global warming, converted into
carbon dioxide discharge amount, was about 280kg. This was about
20 percent less than NEC's conventional products. Its breakdown
was about 110kg in the production stage, about 170kg during
utilization and less than a few kilograms each in the
distribution and disposal stages.
