Carbon-Neutral City in San Francisco Mayor's Environmental Plan

Inefficient fluorescent bulbs were the first targets Tuesday of San Francisco Mayor Gavin Newsom's newly unveiled environmental agenda.

Newsom's SForward program, announced in his inaugural address last week, seeks to lower the city's carbon dioxide emissions by 20 percent below 1990 levels by 2010, and to make city government carbon neutral by 2020. (ABC News10)
