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.

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 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.
