TCO’99 Eco- document
xCongratulations!
You have just purchased a TCO’99 approved and labelled
product! Your choice has provided you with a product developed
for pr ofessional use. Your purchase has al so contri buted t o
reducing t he burden on the environment and also to th e further
development of en vironm ental ly adapt e d electronics products.
xWhy do we have environmentally labelled
computers?
In many countries, environmental labelling has become an
established method for encouragi ng the adap tation of goods and
services to the environment. The main problem, as far as
computers and other electronics equipment are concerned, is that
environmentally harmful substances are used both in the products
and during th eir manufacture . Since it is not so far possible to
satisfactorily recycle the majority of electronics equipment, most
of these potentially damaging substances sooner or later enter
nature.
There are also other characteristics of a computer, such as energy
consumption levels, that are important from the viewpoints of
both the work (internal) and natural (external) environments.
Since al l m etho ds of electricity g ene ra tio n h ave a n e gativ e e ffect
on the envi ronment (e.g. acidic and climate-influencing
emissions, radioac tive waste), it is vital to save energy.
Electr onics eq uipment in offices is often left running
continuously and thereby consumes a lot of energ y.
xWhat does labelling involve?
This product meets the requirements for the TCO’99 scheme
which provides for international and environmental labelling of
personal computers. The labelling scheme was developed as a
joint effort by the TCO (The Swedish Confederation of
Professional Employees), Svenska Naturskyddsforeningen (The
Swedis h Society fo r Natu re Conservation) and Statens
Ener gimyndighet (The Swedish Nati onal Ener gy
Administration).
Approval requirements cover a wide range of issues:
environment, ergonomics, usability, emission of electric and
magnet ic fields, energy consumption and electrical and fire
safety.
