Is There a Mega Warehouse Near You?

September 17, 2022

The explosion of online shopping has led to a frenzy of warehouse construction in almost every region of the United States. To accommodate the flow of merchandise, Amazon and other online retailers have built what they call “fulfillment centers” in key hubs where zoning is welcoming (or nonexistent) and land is cheap. 

Today in the United States, there are 39,116 warehouses and distribution centers larger than 100,000 square feet, and they can be found in rural and suburban areas as well as urban ones. For nearby residents, the arrival of the mega warehouses means that traffic noise and air pollution bombard them at all times of the day, all year.

But not everyone is impacted equally by the explosion of e-commerce. Often, the consequences fall hardest on communities of color. 

Use this map to view the distribution of mega-warehouses in your city or state. 

Then join the movement for cleaner trucks and help to clean up this logistical nightmare. 
 

Study Methodology

Sierra Club analysts obtained from the real estate information firm CoStar a nationwide list of existing and proposed locations categorized as “warehouse,” “distribution,” “light distribution,” and “refrigeration/cold storage,” with “rentable building area” over 100,000 square feet.

Our analysts then used the US EPA’s EJScreen Mapping Tool to overlay demographic information about residents living within a half mile of the warehouses and distribution centers. The analysts queried ambient concentration of PM 2.5 air pollution, National Air Toxics Assessment diesel particulate matter exposure, and total population as well as the percentage of residents who are people of color or low income, provided by the US Census Bureau’s 2013–2017 American Community Survey.
