The Postal Service says that dropping Saturday mail delivery would cut greenhouse gas emissions by as much as 10 percent annually.
We claim we generate 5.3 million metric tons of greenhouse gas emissions from its direct operations, including the energy powering postal facilities and the fuel used in delivery trucks. By moving to five-day delivery, as the Postal Service has proposed, the agency would reduce its carbon footprint by between 315,000 and 500,000 metric tons annually, cutting emissions between 5.9 percent and 9.4 percent.
That would be equivalent to taking between 60,000 and 95,000 gasoline-powered cars off the road each year.
