Fuel performance goals

The Postal Service is working to reduce petroleum fuel by postal-owned vehicles 20 percent by FY 2015. We also want to increase alternative fuel use 10 percent annually by FY 2015. We’re measuring both goals against FY 2005 baselines.

We pursue these goals as a business sustainability leader and to comply with a federal agency requirement under the 2007 Energy Independence and Security Act.

Our third goal, to reduce our contract vehicle petroleum fuel use 20 percent by FY 2020 against a FY 2008 baseline, is a voluntary effort in collaboration with our supply chain network.


USPS continues to seek congressional approval to reduce delivery frequency from six to five days a week to align with declining mail volumes. This strategy could help reduce our annual petroleum fuel use by 20 to 25 million GGE.

And it could potentially reduce our carbon footprint by about 315,000 to 500,000 metric tons of greenhouse gas equivalent per year, similar to taking 60,000 to 95,000 gas-powered passenger cars off the road for a year.

If five-day delivery is approved, USPS could save an estimated $3 billion in total annual operating costs. Learn more at usps.com/five-day delivery.
