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, along with physical
and visual ergonomics and good usability.
The following is a brief summary of the environmental requirements met by
this product. The complete environmental criteria document may be ordered

Brominated flame retardants are present in printed circuit boards, cabling,
casings, and housings, and are added to delay the spread of fire. Up to 30% of
the plastic in a computer casing can consist of flame-retardant substances.
These are related to another group of environmental toxins, PCBs, and are
suspected of giving rise to similar harm, including reproductive damage in
fish-eating birds and mammals. Flame retardants have been found in human
blood, and researchers fear that they can disturb fetus development.
Bio-accumulative1 TCO’95 demands require that plastic components
weighing more than 25 grams must not contain flame retardants with
organically bound chlorine or bromine.
Lead can be found in picture tubes, display screens, solder, and capacitors.
Lead damages the nervous system and in higher doses causes lead poisoning.
The relevant bio-accumulative TCO’95 requirement permits the inclusion of
lead, as no replacement has yet been developed.
