Beginning in July 2013, Procter & Gamble will work with eight transportation carriers to convert up to 20 percent of its North America truck load shipments to natural gas vehicles within two years. By meeting this goal, it is expected P&G will incur savings for the converted lanes and reduce greenhouse gas emissions (GHG) by nearly 5,000 metric tons (or the equivalent GHG emissions from 1,000 passenger vehicles for a year).
