A Sony Vaio has become the 1000th PC to snag the coveted EPEAT eco label. EPEAT, which stands for Electronic Product Environmental Assessment Tool, is a US labelling scheme that was launched in July 2006 and rates computer products on their environmental impact.

The laptop to pass the one thousand mark was the Sony VGN-SR290PDB, a business machine with a 13.3-inch screen, 2.26GHz Intel Core Duo 2 processor and LED back light. It grabbed gold in EPEAT's three-tier rating system, and scored highly for minimising toxic materials and being designed for recycling.

"The EPEAT rating system provides a simple, credible way to measure 'green' when it comes to electronic products, and that has enabled thousands of purchasers to significantly reduce the environmental impact of their computing", said Jeff Omelchuck, EPEAT executive director.

Key criteria for the EPEAT scheme include reduction of toxic materials, energy efficiency and how easy a product is to recycle.
