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 monitors and

other electronic equipment are concerned is that environmentally harmful substances are used

both in the products and during their manufacture. Since it has not been possible so far for the

majority of electronic 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 monitor, such as energy consumption levels, that are

important from both the working and natural environment viewpoints. Since all types 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. Electronic equipment

in offices consumes an enormous amount of energy, since it is often routinely left running

continuously.

What does labelling involve?

This product meets the requirements for the TCO'95 scheme, which provides for international

environmental labelling of monitors. The labelling scheme was developed as a joint effort by the

TCO (The Swedish Confederation of Professional Employees), Naturskyddsforeningen (The

Swedish Society for Nature Conservation) and NUTEK (The National Board for Industrial and

Technical Development 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 among other things restrictions on the presence and use of

heavy metals, brominated and chlorinated flame retardants, CFCs (freons), and chlorinated

solvents. 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 conducts its

operations policy. The energy requirements include a demand that the monitor 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 monitor 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, along with physical and visual ergonomics and good

usability.

Environmental Requirements

Brominated 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. These are related to another group of

environmental toxins, PCBs, which are suspected to give rise to similar harm, including

reproductive damage in fish eating 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.

z TCO'95 demand requires that plastic components weighing more than 25 grams must not

contain organically 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.

z TCO'95 requirement Permits the inclusion of lead since no replacement has yet been

developed.

Cadmium

Cadmium is present in rechargeable batteries and in the colour generating layers of certain

computer displays. Cadmium damages the nervous system and is toxic in high doses.

z TCO'95 requirement states that batteries may not contain more than 25 ppm (parts per million)

of cadmium. The colour-generating layers of display screens must not contain any cadmium.
