Since the mid-1970s, attempts have been made to develop series data on pollution abatement and other environmental expenditures. The issue of defensive expenditures has gained increased momentum in both academic and government policy circles in recent years and quantiﬁcation of defensive expenditures is considered to be crucial for addressing environmental policy. This is particularly the case since these estimates can be used both in the context of environmental monetary accounts and of response indicators.
