Green management measures such as certified environmental management systems
(EMS) or tools like life cycle assessment activities are considered to improve corporate
environmental performance directly by mandating companies to introduce environ-
mental goals and management structures as well as programs to achieve them
(Coglianese and Nash,2001; Johnstone,2001) and indirectly by inducing organizational
learning and providing critical environmental information (Melnyk et al.,2003).Some
econometric studies analyzing this hypothesis actually find a positive impact.For ex-
ample,Potoski and Prakash (2005) show that facilities which are certified according to
the EMS standard ISO 14001,developed by the non-governmental “International Or-
ganization for Standardization” (ISO),reduce more pollution emissions than non-
certified ones.Furthermore,Ziegler and Rennings (2004) and Rehfeld et al.(2006) find
a positive effect of green management measures on green technology,i.e.,future envi-
ronmental product or process innovations.In contrast,Dahlstrom et al.(2003) fail to
show that the ISO 14001 certification improves the compliance with environmental
regulations.Furthermore,Lenox and Nash (2003) point to adverse selection problems of
voluntary environmental programs (looking at the U.S.chemicals industry’s Responsi-
ble Care program) since in their study dirtier firms were more attracted to them.
We attribute this lack of clear-cut results in studies that regress corporate environmental
performance on green management to endogeneity problems.We argue that the corre-
sponding parameter estimates could be biased and inconsistent due to structural reverse
causality and/or unobserved firm heterogeneity (as a specific type of omitted variables).
Structural reverse causality occurs if the direction of causality between green manage-
ment and environmental performance is not clear.For example,the certification of EMS
according to ISO 14001 or the EU EMAS (Environmental Management and Auditing
Scheme) standard could facilitate the realization of technological environmental innova-
tions.However,these certifications could also be more attractive for already environ-
mentally innovative firms.Unobserved firm heterogeneity arises if unobserved firm
characteristics simultaneously influence green management and environmental per-
formance.
