•TCO'99-Ecological requirements for personal computers (TCO applied model only)

Congratulations!

You have just purchased a TCO'99 approved and labelled product! Your choi ce has provided you with a
product developed for professional use. Your purchase has also cont ributed to reducing the burden on the
environment and also to the further development of environmentally a dapted electronics products.
This product meets the requirements for the TCO'99 scheme which provides for an international
environmental and quality labelling labelling of personal computer s. The labelling scheme was developed as
a joint effort by the TCO(The Swedish Confederation of Professional Emp loyees), Svenska
Naturskyddsforeningen(The Swedish Society for Nature Conservation), Statens Energimyndighet(The
Swedish National Energy Administration) and SEMKO AB.
The requirements cover a wide range of issuse: environment, ergonom ics, usability, reduction of electric and
magnetic fields, energy consumption and electrical safety.

Why do we have environmentally labelled computers?

In many countries, environmental labelling has become an established m ethod for encouraging the
adaptation of goods and services to the environment. The main problem, as far as computers and other
electronics equipment are concerned, is that environmentally harmful s ubstances are used both in the
products and during their manufacture. Since it is not so far possible to satisfactorily recycle the majority of
electronics equipment, most of these potentially damaging substance s 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) environ ments. Since all methods of
electricity generation have a negative effect on the environment (e.g. aci dic and climate-influencing
emissions, radioactive waste), it is vital to save energy. Electronics equip ment in offices is often left running
continuously and thereby consumes a lot of energy.

What does labelling involve?

The environmental demands has been developed by Svenska Natur skyddsforeningen (The Swedish Society
for Nature Conservation). These demands impose restrictions on the presence and use of heavy metals,
brominated and chlorinated flame retardants, CFCs(freons)and chlorinated solvents, among othe r things. The
product must be prepared for recycling and the manufacturer is oblige d to have an environmental policy which
must be adhered to in each country where the company implements its opera tional policy.
The energy requirements include a demand that the computer and/or display, afte r a certain period of
inactivity, shall reduce its power consumption to a lower level in one or more stages. The length of time to
reactivate the computer shall be reasonable for the user.
