Environmental Labelling of Personal Computers
Congratulations!
You have just purchased a TCO’99 approved and labelled product!
Your choice has provided you with a product developed for
professional use. Your purchase has also contributed to reducing the
burden on the environment and also to the further development of
environmentally adapted electronics products.
This product meets the requirements for the TCO’99 scheme which
provides for an international environmental and quality 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 Swedish Society
for Nature Conservation), Statens Energimyndighet (The Swedish
National Energy Administration) and SEMKO AB.
The requirements cover a wide range of issues: environment,
ergonomics, 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 method 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 substances 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 substances sooner or later enter nature.

iv
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 all methods
of electricity generation have a negative effect on the environment
(e.g. acidic and climate-influencing emissions, radioactive waste), it is
vital to save energy. Electronics equipment in offices is often left
running continuously and thereby consumes a lot of energy.
What does the environmenal labelling involve?
The environmental demands has been developed by Svenska
Naturskyddsforeningen (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 other things. The product must be prepared
for recycling and the manufacturer is obliged to have an environmental
policy which must be adhered to in each country where the company
implements its operational policy.
The energy requirements include a demand that the computer and/or
display, after 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.
Below you will find a brief summary of the environmental requirements
met by this product. The complete environmental criteria document may
be ordered from:

v
Flame retardants
Flame retardants are present in printed circuit boards, cables, wires,
casings and housings. Their purpose is to prevent, or at least to delay
the spread of fire. Up to 30% of the plastic in a computer casing can
consist of flame retardant substances. Most flame retardants contain
bromine or chloride, and those flame retardants are chemically related
to another group of environmental toxins, PCBs. Both the flame
retardants containing bromine or chloride and the PCBs are suspected
of giving rise to severe health effects, including reproductive damage in
fish-eating birds and mammals, due to the bio-accumulative* processes.
Flame retardants have been found in human blood and researchers fear
that disturbances in foetus development may occur.
The relevant TCO’99 demand requires that plastic components
weighing more than 25 grams must not contain flame retardants with
organically bound bromine or chlorine. Flame retardants are allowed in
the printed circuit boards since no substitutes are available.
Cadmium**
Cadmium is present in rechargeable batteries and in the colour-
generating layers of certain computer displays. Cadmium damages
the nervous system and is toxic in high doses. The relevant TCO’99
requirement states that batteries, the colour-generating layers of
display screens and the electrical or electronics components must not
contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays and switches. It
damages the nervous system and is toxic in high doses. The relevant
TCO’99 requirement states that batteries may not contain any
mercury. It also demands that mercury is not present in any of the
electrical or electronics components associated with the labelled unit.
There is however one exception. Mercury is, for the time being,
permitted in the back light system of flat panel monitors as there
today is no commercially available alternative. TCO aims on
removing this exception when a mercury free alternative is available.
Environmental requirements

vi
CFCs (freons)
The relevant TCO’99 requirement states that neither CFCs nor
HCFCs may be used during the manufacture and assembly of the
product. CFCs (freons) are sometimes used for washing printed circuit
boards. CFCs break down ozone and thereby damage the ozone
layer in the stratosphere, causing increased reception on earth of
ultraviolet light with e.g. increased risks of skin cancer (malignant
melanoma) as a consequence.
Lead**
Lead can be found in picture tubes, display screens, solders and
capacitors. Lead damages the nervous system and in higher doses,
causes lead poisoning. The relevant TCO’99 requirement permits the
inclusion of lead since no replacement has yet been developed.
* Bio-accumulative is defined as substances which accumulate within living organisms
** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
