MIAMI (AP) - Schools in Miami, San Francisco and Chicago will be a little greener thanks to a partnership between a TV network and an environmental media company.

CBS Corp. and EcoMedia of New York City announced Friday that they will sell special advertising content and programming. They will use part of the proceeds to install solar power, green roofs and organic gardens at schools in the three cities.

One school in each city will be chosen in the fall as part of the so-called "Green Schools Initiative." It will cost about $250,000 per school for the upgrades.

EcoMedia wants to expand the program in dozens of schools nationwide over the coming years.

CBS and EcoZone unveiled the program in Miami, a day before the U.S. Conference of Mayors is set to begin.
