LOS ANGELES (AP) — Mayors from 10 U.S. cities took aim at their skylines Wednesday, pledging to reduce greenhouse-gas emissions from their buildings.
Businesses and homes are a major source of carbon-dioxide pollution in cities, with most of it coming from the burning of fossil fuels for heating, cooling and lighting. Many of the participating cities — Atlanta, Boston, Chicago, Denver, Houston, Kansas City, Mo., Los Angeles, Orlando, Fla., Philadelphia and Salt Lake City — already are working toward making their building stock more energy efficient.
