Why do w e ha ve environmentally labelled comput-

ers?

In many countries, envir onm ental labelling ha s become an es tablished
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 i n the products and during the manu fac turing. Since it ha s not
been possi bl e for t he majority of el e ct roni cs equipmen t to be recycled in
a satisfactory way, most of these potentially damaging substances sooner
or later en ter Nature.
There are also other characteristics of a computer, such as energy
consum pti on levels, that are important fr om the vie w points of both t he
work (internal) and natural (external) environments. Since all methods of
conventional ele ct ri ci ty generation ha ve a negative effect on the
environ ment (acidic and climate -influencing emissions, radioactive
waste, etc.), it is vital to conserve energy. Electronics equipment in offices
consume an enormous amount of energy since they are often left running
continuously.

xWhat does labelling involve?

This product meets the re quirements for the TCO’95 schem e whi ch
provide s for in ternational and envi ronmental labell in g of pe rsonal
computers. The labelling scheme was developed as a joint effort by the
TCO (The Swedish Confede ra ti on of Professional Employees),
Naturskyddsforeningen (The Swedish Society for Nature Conservation)
and NUTEK (The National Board for Ind ust ria l a nd T ec hni c al
Dev elopm ent in Sweden ).
The requirements cover a wide range of issues: environment, ergonomics,
usability, emission of electrical and magnetic fields, energy consumption
and electrical and fire safety.
The environmental demands concern restrictions on the presence and use
of heavy metals, brominated and chlorinated flame retardants, CFCs
(freo ns) and chlorina t ed sol ve nts, among ot he r thi ngs. The product must
be prepared for recycling and the ma n ufacturer is obliged to ha ve an
environ mental plan which must be adhered to in eac h country where the
company implements its operational policy.
The energy requirements include a demand that the computer and/or
display , afte r a c ert ai n period of inactivity, shall red uce its power
consumption to a lower level in one or more stages. The length of time to
reactivate the computer shal l be r ea s ona ble for the user.
Labelled products must meet strict environmental demands, for example,
in respec t of the reduct ion of electric and magnetic fields , ph ysic al and
visual ergonomics and good usability.

requirements met by this product. The complete environmental criteria

TCO’95 is a co-opera tive project betwe e n TCO (The Swedish
Confederation of Professional Employees), Naturskyddsforeningen
(The Swe dish Society for Nature Conserva tion) and NUTEK (The
National Board for Industrial and Technical Development in Sweden).

xEnvironmental Requirements

Brominated flame retardants

Brominated flame retardants are present in printed circuit boards, cables,
wires, casings and housings. In turn, they delay the sprea d of fi re. Up to
thirty perc ent of the plasti c in a comput er c asi ng can consist of flame
retardant substances. These are related to another group of environmental
toxins, PCBs, which are suspected to give rise to similar harm, including
reproductive da mage in fisheating birds and mammals, due to the bio-
accumulative* processes. Flame retardants have been found in human
blood and research ers fear that disturbances in fo etus development may
occur.
TCO’95 demand requires that plastic components weighing more than 25
grams m ust no t c ontain organic al ly bound chlorine and bromine.

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.
TCO’ 95 re qui rement perm it s the inc lu s ion of le ad since no replacement
has yet been developed.

Cadmium**

Cadmiu m is prese nt in rec har geab le ba tter ies an d in the c olour gener atin g
layers of certain computer displays. Cadmium da m ages the ne rvou s
system and is t oxi c in high doses.
TCO’95 requirement states that batte rie s may not contain mo re than 25
ppm (parts per milli on) of cadmium. The colour-generating l ayers of
display screens must not contain any cadmium.

Mercury**

Mercury is sometime s found in batteries, rela ys and switch es. Merc ury
damages the nervous system and is toxic in high doses.
TCO’95 requirement states that batte rie s may not contain mo re than 25
ppm (pa rts pe r mi llion) of mercu ry. It also demands that no mercury is
present in any of the electrical or electronics components concerned with
the display unit.

CFCs (freons)

CFCs (freons) are sometimes used for washing printed circuit boards and
in the manufacturing of expanded foam for packaging. CFCs break down
ozone a nd thereby dam a ge the ozone layer i n the stra to sphere, causing
increased reception on Earth of ultr aviolet light with consequent i ncreased
risks of skin cancer (malign ant me l ano ma).
The re levant TCO’ 95 requi rement: Neit her CFCs no r HCFCs m ay be use d
during th e manufacturing of the prod uct or its packaging.
* Bio-accumulative is defined as substances which accumulate within
living organisms
** Lead, C admium and Mercu r y are heavy metals wh ich are Bio-
accumulative.
