Todays Goals Objectives
How do we define, measure, assess, and/or
predict the environmental performance or
condition of different systems?

• Learning Objectives
• Know why they are important.
• Understand some basic issues regarding
  definitions, terminology, and characteristics .
• Make you aware of some indicator classification
  schemes and list examples.
• Understand importance to ECDM-related efforts and
  apply concepts.

4
Motivating Questions

• Imagine a world without measures, metrics or any
  way of indicating the condition of things
• How would you assess anything?
• How would you improve anything?
• Imagine if different companies had different or
  vague metrics
• How would you compare or benchmark them?
• How would you compare and improve their products?

5
Why Important?... Some reasons
You cant manage what you cant or dont
measure. Not everything that can be counted
counts, and not everything that counts can be
counted.

• Raise awareness and understanding
• Measure progress towards goals
• Support decision making

6
One Definition

• Metric a quantitative measure or derivation
  from two or more measures, which may not
  necessarily indicate something useful to
  particular observers
• (a measure of something that does not necessarily
  indicate something useful)
• Indicator a characteristic that indicates a
  quality or state of a system
• (something that indicates something useful to
  someone based on one or more metrics,
  observations or both)

11
What is or can be a good indicator?

• Appropriate for the task
• Based on readily available, accurate and
  verifiable data
• Easy to apply and evaluate
• Simple yet meaningful
• Allows comparisons with other companies
• Politically supported and accepted at different
  levels
• Enhances understanding of the context of
  application
• Has clear, transparent and standard methodology
  for data gathering, processing and monitoring

HW
12
What is a bad indicator?
Not everything that can be counted counts

• One that is not appropriate to the task
• Indicators do not represent the underlying
  mechanics or functional relationships of the
  system being considered this could lead to
  undesired or less than desired results if one
  does not understand the system well (Reap 2004)
• Examples
• Office paper consumption per hour
• Paper clip waste generation per month

13
Quantitative vs. Qualitative

• Most people restrict the definitions of
  indicators to numerical (cardinal) variables
• Indicators could be qualitative by being nominal
  or rank (ordinal) variables
• Example of qualitative
• Smells
• Vehicle noise and vibration
• Oiliness of water
• When are qualitative indicators preferable?
• Can a quantitative indicator be made
  qualitative and vice versa?

HW
14
Lagging vs. Leading

• Lagging indicators are those that indicate what
  has already happened (past)
• Leading indicators are those that indicate what
  may happen (future)
• Most companies use lagging indicators
• Examples of leading indicators
• Amount of soil eroded
• Deforestation rate

18
Scalars vs. Vectors

• A vector is a number of indicators presented
  simultaneously to give a picture of environmental
  conditions (a.k.a. an environmental profile)
• A scalar is a single number generated by
  aggregation from two or more values (a.k.a. an
  index)
• Varying preferences
• Some prefer data in simplest form possible
  accept distortion introduced from simplification
  (scalar)
• Some prefer data in most complete form possible
  accept resulting complexity (vector)

HW
19
Value Judgments in Scalars

• Varying preferences
• Internalize value judgments
• Externalize value judgments in terms of worth or
  utility
• Qualitative evaluations e.g., Aesthetic values
• Pretty, ok, ugly
• Establishing preferences in form of weights or
  functions
• House preference function f(x, y), where x
  cost, y size
• where ws numerical representation of your
  preference for x or y, Ts target for x or y
• Difference or ratio with respect to a standard,
  target, etc.
• Concentration of heavy metals in wastewater vs.
  regulated

Different Classifications

• Media Approach
• Goal Approach
• Sector Approach
• Ad hoc Nomenclatures or Listings
• Lowell Center for Sustainable Production (LCSP)
  Indicator Framework
• International Standard Organization (ISO) 14031
• Global Reporting Initiative (GRI)
• Facility Reporting Project (FRP)
• At least 23 groups working on environmental
  performance measurements (Ranganathan 1998)

LCSP Indicator Framework

LCSP Indicator Framework Definitions Examples

• Level One Indicators measure a facilitys level
  of compliance with regulations and/or its
  conformance with industry/association standards
  (e.g., of OSHA citations, of recordable
  injuries, cost of environmental liabilities)
• Level Two Indicators measure the facilitys
  inputs, outputs and performance (e.g., amount
  hazardous waste, total EHS operating costs, of
  employees receiving EHS training, of community
  outreach activities)
• Level Three Indicators measure the potential
  impact that the facilitys presence and
  activities have on its workers, the surrounding
  environment and communities (e.g.,
  eutrophication, disturbance of local
  environments)
• Level Four Indicators measure the lifecycle
  stages effects of their actions, which imply
  applying the Level 1-3 indicators throughout the
  supply chain (e.g., suppliers from local area
  and receiving EHS training, suppliers
  supporting take-back policies and without EHS
  violations)
• Level Five Indicators measure how a facilitys
  production activities affect the larger picture
  of sustainable society (e.g., renewable
  materials used at a rate lower or equal to the
  renewal rate, community quality of life, worker
  health status compared to other companies in
  industry)

25
ISO 14031 Indicator Framework
HW

• Environmental Performance Indicators (EPIs)
• Operational Performance Indicators (OPIs)
• Management Performance Indicators (MPIs)
• Environmental Condition Indicators (ECIs)

Modified from (ISO_14031 1999).

Example of widely used indicators

• A survey by the Global Environmental Management
  Initiative (GEMI) in 1995 revealed the following
  top measures by various companies (GEMI 1998)

29
How do you choose indicators?

• Figure out the issue, principle, goal and
  strategy the indicator addresses
• What is the purpose?
• External or internal environmental reporting
• Product or process redesign
• Corporate or government policy making
• Is it currently an important metric to your
  company, industry sector, local community,
  nation, world?
• Is it suggested and accepted by different
  researchers and non-government organizations?
• Is it an input to a more detailed and meaningful
  environmental assessment model?
• Is it hazardous or non-hazardous? Regulated or
  not?
• Is it a big hitter? (20/80 rule)

HW
30
EPAs Approach

• EPAs Environmental Indicator Initiative has
  developed different documents on evaluating the
  utility of certain indicators for environmental
  management and national contexts
• Various documents http//www.epa.gov/indicators/k
  eydocs.htm.
• Indicator quality review format
  http//www.epa.gov/indicators/docs/QualityReviewFo
  rmat.pdf.

They may be helpful in thinking through some
other aspects of developing and evaluating the
utility of indicators.

Summary Main Points

• Indicators are important to support decision
  making
• Different definitions of indicators metrics
  abound here you have some and a relationship
  diagram to help you select or develop relevant
  indicators to particular issues
• Indicators can be qualitative, vectors, scalars,
  leading, which can useful in different situations
• Many indicator classifications, frameworks, and
  lists are out there you should use them when
  working with indicators
• Choosing the good indicators may not be obvious
  at times choose carefully since these will
  guide many of your measurement/data gathering
  efforts
