SAN FRANCISCO (AP) - Apple's withdrawal from an environmental ratings registry has prompted at least one city - San Francisco - to stop buying its computers.

The decision does not apply to iPads or iPhones. But Francis Tsang, spokesman for Mayor Edwin Lee's office, says the city's rules require that laptops, computers and monitors comply with the registry's requirements.

Late last month, Apple Inc. told the nonprofit EPEAT, short for Electronic Product Environmental Assessment Tool, to remove its products from its registry. It also plans to stop submitting its products to EPEAT for environmental ratings.

EPEAT is an industry standard that seeks to make it easier for customers to buy environmentally friendly electronics. Manufacturers still participating include Dell Inc., Hewlett-Packard, Lenovo, Samsung and Sony.

Apple did not respond to messages for comment Wednesday afternoon.
