ENVIRONMENTAL
VALUATION AND
COMPENSATION
A. THE SCOPE AND NATURE OF
ENVIRONMENTAL DAM AGE
Harm or damage suffered as a result of ongoing pollution, accidents or
spills, general degradation, or the over-exploitation and mismanage-
ment of resources may take many forms. Physical contamination of
a short- or long-term nature is an obvious example, with or without
destruction of plant and animal life or biodiversity loss. In severe situa-
tions it is also possible to imagine that contamination will have perma-
nently or irreversibly undermined t he regenerative capacity or resilience
of the affected ecosystem. Losses here may also entail the reduction or
elimination of what we are coming to appreciate as ecological services
such as water supply, climate stabilization, nutrient cycling, or pollin-
ation. Insofar as human populations are concerned, individuals may
suffer adverse health effects, physical damage to property, or economic
losses, singly or in combination. On occasion it is possible to speak of
entire communities as the victims of environmental harm, arising, for
example, from the contamination of food and water supplies. Finan-
cial compensation might then focus on payments to those — including
the public — who have suffered losses or incurred expenses associated
with remedying environmental damage or taking measures to prevent
the spread of such damage.1

In The Costs of Pollution in Canada, the Inter national Institute for Sus-
tainable Development (IISD) suggested a comprehensive approach. Pol-
lution, this report suggests, imposes costs in three broad categories on
households, businesses, and governments: direct welfare costs, costs for
goods and services, and declines in the value of property and natural
capital.2 In terms of direct welfare costs from pollution, for example, the
report mentions health care expenditures, suggesting a 2015 estimate
of $39 billion in that category. Air pollution alone accounted for $36 bil-
lion of estimated health care costs related to pollution. Other sources
of pollution-related health care costs include tap water-borne pathogens,
heavy metals, noise pollution, and extreme weather.3 Pollution also con-
tributes to lost income and increased costs such as lost labour produc-
tivity, increased infrastructure costs, crop losses, and contaminated site
reclamation. Such expendit ures were estimated at around $3.3 billion for
2015.4 The challenges of formulating reliable estimates were, of course,
acknowledged, given a range of uncertainties. Extreme weather linked
to climate change is a prime example of this uncertain environmental
costing.5 Turning to the third category of pollution costs, the IISD analy-
sis described different ways that pollution contributes to the decline in
the value of property and natural capital, including the impact of algae
blooms on waterfront property values and the decli ne in forests and far m-
land from environmental st ressors. However, the study determined that it
is not currently possible to assess the value of these costs to Canadians.6
Many aspects of env ironmental damage and associated costs a s just
discussed fall outside the scope of compensation as generally under-
stood in the context of tort claims. For purposes of comparison it is
worthwhile to review that approach prior to examining alternative
approaches to environmental losses:
Traditionally, the courts considere d the only measure of compensation
for damage to property to be the diminution in value caused by the
tortfeasor’s wrong, that is, the difference between the property value
before and after the occurrence of damage. The cost of restoring or
repairing the property, if considered at all, was simply regarded as
a means of determining the diminution of value. However, in many
