EU and US adopt new Energy Star criteria for PCs

The European Commission and the US Environmental Protection Agency have agreed to introduce revised energy efficiency criteria for awarding the voluntary Energy Star ecolabel to manufacturers of computer monitors.

A commission decision published on Thursday includes tighter tier 2 efficiency requirements for sleep mode and new testing requirements for the ambient temperature and relative humidity of input AC power.

Existing criteria for computer monitors with diagonal screen sizes below 30 inches will remain valid until 30 October. Criteria for diagonal screen sizes from 30 to 60 inches will be replaced on 30 January 2010.
