Empirical evidence on environmental performance and operating costs

Abstract

Theoretical arguments suggest that better environmental performance can lead to cost advantages through a more efficient use of resources and higher labor productivity. To provide empirical support for these arguments, we investigate how environmental performance affects operating costs using a sample of 785 U.S. firms for the period 2006-2014. We find that better environmental performance is negatively associated with direct production costs, but increases overhead costs. Because direct production costs have a larger impact than overhead costs, aggregate operating costs decline as environmental performance improves. To deal with endogeneity and to interpret the results causally, we use an instrumental variables approach.
