TCO 99
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.
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?
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 Swedish Society for Nature
Conservation) and Statens Energimyndighet (The Swedish National Energy
Administration).
Approval requirements cover a wide range of issues: environment, ergonomics, usability,
emission of electric and magnetic fields, energy consumption and electrical and fire
safety.
The environmental 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.
Labelled products must meet strict environmental demands, for example, in respect of the
reduction of electric and magnetic fields, physical and visual ergonomics and good
usability.
