Beers Skanska believes that ISO 14001 certification helps to
change the behavior of a company by making environmental
management an important part of every project ~E. P. Hatch, personal
communication, August 2, 2002!. The certification process
and frequent audits force employees to be continually educated. If
a firm implements an EMS, but does not go through frequent
third-party audits, there is not the pressure to maintain the EMS
and continually make improvements.
