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. With the growing 
manufacture and usage of electronic equipment throughout the world, there is a recognized 
concern for the materials and substances used by electronic products with regards to their 
eventual recycling and disposal. By proper selection of these materials and substances, the 
impact on the environment can be minimized. 
 
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. Electronic equipment in offices is often left running continuously, resulting in 
unnecessary consumption of large amounts of energy and additional power generation. 
From the standpoint of carbon dioxide emissions alone, it is vital to save energy. 
 
What does labelling involve? 
 
The product meets the requirements for the TCO’99 scheme which provides for 
international and environmental labelling of personal computers and/or displays. 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: ecology, ergonomics, emission of 
electrical and magnetical fields, energy consumption and electrical safety. 
 
Ecological criteria impose restrictions on the presence and use of heavy metals, brominated 
and chlorinated flame retardants, and other substances. The product must be prepared for 
recycling and the manufacturing site(s) shall be certified according to ISO14001 or EMAS 
registered. 
 
Energy requirements include a demand that the system unit 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 system unit shall be reasonable for the user. 
 
Labelled products must meet strict environmental demands, for example, in respect of the
