1. Greening our Fleet Utah Governors Energy Summit April 2014 Waste Management’s Natural Gas Fleet

2. WM’s Vehicle Inventory WM operates 32,000 vehicles Over 17,000 are Class 8 collection trucks 12,000 support vehicles include large, off-road equipment used at landfills “yellow iron,” delivery vans and supervisor trucks.

3. WM’s Fleet Goal: Reduce emissions and increase fuel efficiency by 15% by 2020 WM will replace 80% of its new class 8 vehicles with natural gas trucks. We will build/upgrade 25 natural gas fueling stations each year We are investing in public fueling stations at most sites Achieving our goal will replace 350 million gallons of diesel fuel with Natural Gas and will eliminate 3.5 million metric tons of carbon dioxide.

4. Emissions Reduction: Benefits Smog-producing NOx emissions are reduced up to 50% compared to 2010 diesel engines and even more compared to the older diesel engines we are replacing; Greenhouse gas emissions (GHG) are reduced by 21% over standard diesel engines; and When we can use LNG or CNG derived from landfill gas versus standard pipeline gas GHG can be reduced by over 90%.

5. Natural Gas Vehicles & Infrastructure Transitioning first in large districts with over 75 trucks Developing capabilities for fueling at smaller sites Continue to invest in our fleet and infrastructure to facilitate this transition Transition strategy Page 5 The alternative fuel and fleet industry recognizes that natural gas will be the best option for heavy duty vehicles for the foreseeable future

6. Current Status of WMs Green Fleet Transition Over 3,100 natural gas trucks on the road today - the largest fleet of heavy duty natural gas trucks in North America In 2012 we achieved our 2020 emissions and fuel efficiency goals -- replacing 350 million gallons of diesel fuel with Natural Gas and reducing 3.5 million metric tons of carbon dioxide We are investing in new natural gas fueling stations to support our fleet: We operate 61 natural gas fueling stations WM has natural gas operations in 28 states and 2 Canadian provinces 19 stations have public access & another 8 have public access for pre-approved customers

9. Future Plans Natural gas engines are flexible and can be powered by other renewable fuels such as bio-methane WM will continue to experiment with new technologies as they become economically viable. WM is transitioning off-road, heavy equipment to alternative fuels. Testing four diesel-electric hybrid bulldozers that have a dramatically different life cycle than our traditional power train tractors as well as improved fuel efficiency. WM considers natural gas trucks to be a bridge to future technologies. We are striving to move towards a true zero emissions vehicle (ZEV)
