Congratulations! You have just purchased a TCO’99 

approved and labeled 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.

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 the manufacturing. 

Since it has not been possible for the majority of electronics equipment 

to be recycled in a satisfactory way, 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 conventional electricity generation have a negative effect on the 

environment (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.

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).

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 (freons) and chlorinated solvents, among other things. The product 

must be prepared for recycling and the manufacturer is obliged to 

have an environmental plan 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.

Flame retardants are present in printed circuit boards, cables, wires, 

casings and housings. In turn, they delay the spread of fire. Up to 

thirty percent of the plastic in a computer casing can consist of flame 

retardant substances. Most flame retardants contain bromine or 

chloride and these are related to another group of environmental 

toxins, PCBs, which are suspected to give rise to severe health effects, 

including reproductive damage in fisheating birds and mammals, 

due to the bioaccumulative* processes. Flame retardants have been 

found in human blood and researchers fear that disturbances in foetus 

development may occur.

TCO’99 demand requires that plastic components weighing more than 

25 grams must not contain flame retardants with organically bound 

chlorine and bromine. Flame retardants are allowed in the printed 

circuit boards since no substitutes are available.

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’99 requirement permits the inclusion of lead since no 

replacement has yet been developed.

Cadmium is present in rechargeable batteries and in the 

colourgenerating layers of certain computer displays. Cadmium 

damages the nervous system and is toxic in high doses.

TCO’99 requirement states that batteries, the colourgenerating layers 

of display screens and the electrical or electronics components must 

not contain any cadmium.

Mercury is sometimes found in batteries, relays and switches, 

Mercury damages the nervous system and is toxic in high doses.

TCO’99 requirement states that batteries may not contain any 

Mercury. It also demands that no mercury is present in any of the 

electrical or electronics components associated with the display unit.

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 consequent increased risks of skin cancer (malignant 

melanoma).

The relevant TCO’99 requirement; Neither CFCs nor HCFCs may be 

used during the manufacturing and assembly of the product or its 

packaging.

*Bio-accumulative is defined as substances which accumulate within 

living organisms.

**Lead, Cadmium and Mercury are heavy metals which are  

Bio-accumulative.
