The Benefits of Ecoefficiency
Ecoefficiency essentially
maintains that organizations
can produce more useful
goods and services while
simultaneously reducing
negative environmental
impacts, resource
consumption, and costs.
12 -4
Incentives and causes for increased
efficiency:
1) Customers are
demanding products
that are
environmental
friendly

Environmental Quality
Cost Model
Environmental costs are costs that are incurred
because poor environmental quality exists or may
exist.
Environmental costs can be classified in four
categories: prevention costs, detection costs, internal
failure costs, and external failure costs.
Classification of Environmental
Costs by Activity
Prevention Activities
Evaluating and selecting suppliers
Evaluating and selecting pollution control equipment
Designing processes
Designing products
Carrying out environmental studies
Auditing environmental risks
Developing environmental management systems
Recycling products
Obtaining ISO 14001 certification
12 -9
Classification of Environmental
Costs by Activity
Detection Activities
Auditing environmental activities
Inspecting products and processes
Developing environmental performance measures
Testing for contamination
Verifying supplier environmental performance
Measuring contamination levels
12 -10
Classification of Environmental
Costs by Activity
Internal Failure Activities
Operating pollution control equipment
Treating and disposing of toxic waste
Maintaining pollution equipment
Licensing facilities for producing contaminants
Recycle scrap
12 -11
Classification of Environmental
Costs by Activity
External Failure Activities
Cleaning up a polluted lake
Cleaning up oil spills
Cleaning up contaminated soil
Settling personal injury claims (environmentally related)
Restoring land to natural state
Losing sales due to poor environmental reputation
Using materials and energy inefficiently
Receiving medical care due to polluted air (S)
Losing employment because of contamination (S)

Environment Product Costs
The environmental costs of
processes that produce,
market, and deliver products
and the environmental
postpurchase costs caused by
the use and disposal of the
products are examples of
environmental product costs.
12 -18
Full environmental
costing is the
assignment of all
environmental costs,
both private and
societal, to products.
12 -19
Full private
costing is the
assignment of
only private cost
to individual
products.
Private costing is probably a good starting point
for many firms.
Private costs can be assigned using data created
inside the firm.

Product stewardship is
the practice of
designing,
manufacturing,
maintaining, and
recycling products to
minimize adverse
environmental impacts.
12 -22
Life-cycle assessment
identifies the
environmental
consequences of a product
through its entire life
cycle, and then searches
for opportunities to obtain
environmental
improvements.

Impact Analysis
Impact analysis
assesses the
environmental
effects of competing
designs and provides
a relative ranking of
those effects.
12 -31
Improvement Analysis
Improvement analysis
has the objective of
reducing the
environmental impacts
revealed by the
inventory and impact
steps.
12 -32
Environmental Perspective
Five core objectives for the environmental
perspectives:
Minimize the use of raw or virgin materials
Minimize the use of hazardous materials
Minimize energy requirements for production and
use of the product
Minimize the release of solid, liquid, and gaseous
residues
Maximize opportunities to recycle
