impacts and benefit their
The site went online in the
October of 2007 and continued in operation

Eventually, the cost of maintaining the

The site provided data about

Environmental Protection Agency. Over
23,000 facilities were shown on the
map. We invited managers from
each facility to post information on their
efforts to protect the environment.
About 1000 managers provided us with some
information about their facility's
efforts. Approximately 300 allowed us

The facilities are color coded
roughly by their impact. Those that
marked with a redder color have more
emissions or more toxic emissions; those
with a bluer color fewer or less toxic
emissions. For more information on how
we caclulated these effects, please see the

the facilities that voluntarily reported
information to MapEcos about the actions
they were using to reduce their emissions.
The site was visited by tens
of thousands of people. The following

users in a 30 mile radius is coded by the

Although MapEcos only coverd
