ed by differences in the management practices and characteristics of the fi
rms Using data from a national survey, firm visits, and phone interviews, t
his research assesses the pervasiveness of the adoption of environmental ma
nagement practices. It also assesses whether the adoption of these practice
s is related to leadership in environmental innovation and performance. Thi
s paper shows high levels of adoption of several practices for improving en
vironmental innovation and performance. Firms are using practices such as t
otal quality management, certification of suppliers, R&D, and the involveme
nt of employees in innovation and training to integrate environmental manag

option levels of environmental practices have substituted cleaner materials
and changed their production processes for cleaner production, and they ar
e leaders in reducing their generation of chemical waste.
