Mercury is sometimes found in batteries, relays and switches. Mercury damages the nervous
system and is toxic in high doses.
TCO'95 requirement states that batteries may not contain more than 25 ppm (parts per million)
of mercury. It also demands that no mercury is present in any of the electrical or electronics
components concerned with the display unit.
CFCs (freons) are sometimes used for washing printed circuit boards and in the manufacturing of
expanded foam for packaging. CFCs break down ozone and thereby damage the ozone layer in
the stratosphere, causing increased reception on Earth of ultraviolet light with consequent
increased risks of skin cancer (malignant melanoma).
The relevant TCO'95 requirement: Neither CFCs nor HCFCs may be used during the
manufacturing of the product or its packaging.
TCO'99-Ecological requirements for personal computers (TCO'99 applied model only)
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
This product meets the requirements for the TCO'99 scheme which provides for an international
environmental and quality labelling 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 issuse: 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.
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 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.
