TCO’99 STATEMENT 

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 th e 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 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 issues: 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 

generat ion 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 the environmental 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 ch lorinated 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.
