Better Operations


We charge our fleet of more than 32,000 vehicles with providing reliable everyday waste collection for our customers while minimizing its environmental impact. We’ve set bold goals, utilized smart solutions and leveraged innovative technology to realize progress. Sixty-six percent of our residential routes run with automated or semiautomated equipment, which reduces the number of times our employees must exit the truck while collecting trash and recyclables, which in turn reduces accidents.

That effort started in 2007 when we set our first goal to reduce CO2 fleet emissions by 15 percent, which we achieved in 2011 primarily by transitioning our fleet of collection vehicles from diesel to cleaner-burning natural gas. With a vision to create a near-zero emissions collection fleet, we’re now working toward a science-based target to reduce emissions associated with our fleet 45 percent by 2038, against a 2010 baseline, and from 2010 through 2017 we have reduced fleet emissions 28 percent.

Key to achieving this ambitious goal is a commitment to invest approximately $400 million annually in the cleanest near-zero-emissions trucks available. At the end of 2017, our natural gas fleet counts 6,536 trucks, which comprise the largest heavy-duty natural gas truck fleet of its kind in North America. Our vehicles powered by compressed natural gas (CNG) emit nearly zero particulate emissions, cut GHG emissions by 15 percent and are quieter than diesel trucks. For every diesel truck we replace with natural gas, we reduce our use of diesel fuel by an average of 8,000 gallons per year along with a reduction of 14 metric tons of GHG emissions annually.
