A while ago I posted a request for info on Pollution Prevention (P2)
metrics that work across industry sectors.  Thanks to those who responded,
a digest is included below.  In summary, it is as one would guess, there
are no projects that have developed a p2 progress measurement approach
BASED ON MATERIAL FLOWS that works across industry sectors, but there are a
few publications that talk about how it might be done.  There are some
working metrics for progress WITHIN sectors, and of course metrics for
progress within plants or processes.  The digest of responses is below -
thanks to all who responded!

Several of us have been chatting about the alternative to metrics on
materials, namely simple indicators of management behavior.  It's like
this:  P2 is hard to define but you know it when you see it.  (yes I know
this is stealing a cliche).  The most important things you see are:

a)  They measure waste creation and management costs (so they know what's
the costs/problems are)
b)  They have a functioning EMS focused on improvement, not just compliance
(so they are consciously doing something about the P2 problem)

c)  They participation in P2 networks, workshops and meetings (so they get
the best info about what to do)
d)  They reduce toxics [as well as pollution and waste] in at least one
area (so they know they can do it)

Rob Guillemin of NEWMOA has just pointed out to me that "these four metrics
fall into three classic P2 measurement tracks:
>1) costs (a)
>2) corporate behavioral (b and c)
>3) waste reduction (d)"

Simpler is better!  Thanks Rob.  I would therefore propose that, given we
need some ways of determining whether a sector is advancing in P2 as a
result of programmatic efforts by agencies, we could much more easily
measure progress through such behavioral rather than materials indicators.
After all the point of metrics is to learn where to apply the next effort,
and if a company has these behaviors in place then agencies should move on
to other problem areas.

Well that's my opinion anyway.  Further discussions are invited!

By the way, I am moving from Manila Philippines and the Asian Institute of
Management back to Seattle Washington this summer, and I have a new email
address:  bhamner@hotmail com.  I will keep teaching and consulting on P2
and Sustainable Business around Asia, and hopefully the US too.

I have been using a measure of the reduction in the activity-based cost of
operations.  This works great in sectors.  Companies would look at the
that were eliminated or minimized significantly.  What activities are
as a result of not having the waste?  What savings are there by not buying
materials that you are throwing away in the waste?  What is the cost of
regulations avoided?  It is best to draw a "before" and "after" process map
the major innovations in the industry.  A focus group can be used to
the activities that are avoided in the "after" process map.  This measure
both at the facility and at the sector level.  My paper entitled
"Activity-Based Costing for EHS Improvement" in the Winter 1998 issue of
Pollution Prevention Review addresses this subject.  I am hoping to have
all my
Systems Approach reprints on my web site in a few weeks.  Might want to
it out.  http://www.hsph.harvard.edu/courses/eh270cd

There is a good way to get around the "not waste reduction concern."
maps of the "before" case need to be tied to specific expenditures
orders) to DEMONSTRATE what changes were made to get to the "present" map
cases.  We are using this in the metal finishing category here in the U.S.
They have to go back and establish a base year in 1991 with few records to
so.  We are helping them recontruct a process map for that time, and then
having them provide proof (purchase orders, etc.) that the changes made to
reach the current configuration were in fact prevention and not recycle or
treatment.  It is amazing how many financial records are kept forever in
storage bins. This is being done for an EPA Common Sense Initiative.

In Portland, Oregon, the P2 Program does not focus on a sector basis;
we focus on environmentally sensitive areas within our community.
Perhaps the group you are looking at might want to consider this

Margaret Nover
Since we are hoping to write gainshare
agreements with future manufacturing clients when we can, we have struggled
mightily with this problem of measurement.  To answer your first question,
I hesitate to point you to an article, since everything that I have read
assumes far more more control of variables than I have ever seen in an
industrial facility.  If it takes a single counterexample to disprove a
theoretical construct, these things are dead meat.

I will offer a study that we did for USEPA on applications of
"environmental cost accounting" to electroplating for the purposes of
identifying and analyzing  process improvement opportunities.  I offer this

not because it showed ECA to be useful; it did not.  Rather, I think the
specifics of how we analyzed things like data quality and availability
might give you the ammo you need to back your requesters down.

I think the only progress worth measuring would be on substitution of more
benign inputs in place of toxic nasties.  Then it becomes a simple matter
of saying what the substituion was and why it was done.  I also with
trepidation offer the possibility of measuring change in input quantities,

--inputs are already being allocated to sources
--inputs can be adjusted for production volume
--the change was a no-brainer, e.g., using too much water to rinse or cool

Wander too far from these constraints and I think the posibilities of
double- and triple-counting the same "progress" multiply like small

>I like the 4 points approach -- from a P2-practitioner standpoint, your
assessment is right on point. I'd like to combine it, however, with some
more specific indictors of P2 progress, because there is a lot of
"wiggle room" in those 4 points, and you don't want to see companies
adopting half-hearted P2 measures and getting full public relations
credit for their work. Or maybe we don't care what kind of PR benefit
they get, as long as they start down the P2 road....

In any case, the the US regulatory context, there is still a strong need
for quantitativeP2 measures that policy-makers & enviro groups can use
to get a sense of how a particular industry sector is doing overall. EPA
is very intersted in "numerical progress" (largely driven by the
Government Performance and Review Act -- or whatever GPRA stands for).

On a related topic, we're developing a software tool that helps
companies evaluate whether their EMS is P2-oriented and whether it has
all the components in it that are likely to lead to environmental

I*m in EPA*s Design for the Environment (DfE) Program.  In case you*re not
familiar with it, DfE is a sector-based partnership program that promotes
P2 through incorporating environmental considerations into the design of
products, processes, and technical and management systems.  Although DfE
currently doesn*t have any publications on P2 measurement, I wanted to
refer you to a report I found helpful and pass along some things to
consider when deciding how to measure P2.

As a starting point, I recommend you look at EPA*s recent report entitled,
*Pollution Prevention 1997 - A National Progress Report.*  Chapter 7 is
devoted to measuring P2.  The rest of the book gives a solid overview of P2
and its complexities.  The book is also a great reference of *who*s who* in
P2.  You should be able to find contact names in organizations and
companies who are involved in P2 in the sectors in which you are most
interested.  You can order this book by calling EPA*s P2 Information

Clearinghouse at 202-260-1023.  Ask for document # EPA 742-R-97-00.

Off the top of my head, here are some things to consider when developing P2
measures for industry sectors:

1) P2 is multi-faceted.  Therefore, use multiple measures that capture
different aspects.

2) Many commonly used measures reflect the amount of pollution reduced, as
opposed to the amount prevented.  *Reduced pollution* measures include the
actual change or percent change in the quantity released of a specific
substance.  To make such measures more reflective of the amount prevented,
one should adjust them to reflect the level of activity or output.  Two
ways to do this are through indexing and using ratios (emissions/volume of
output).  Then compare these adjusted measures before and after the P2

3) Try to develop a multi-media measure that captures pollution prevented
through all media (air, land, and water).  As you know, reduced water
emissions may mean increased air emissions and not P2.

4)  Similarly, one could develop multi-chemical measures.  Such measures
could take into account the relative hazard of each chemical.  The Indiana
Pollution Prevention and Safe Materials Institute has developed a P2
measurement that incorporates hazard rankings for chemicals.

5) Use input or technology change measures.  For sectors where there is
little pollution information available, or if the particular P2 program you
are evaluating addresses a relatively small part of the sector*s overall
activity, input and tech change measures may be not only easiest to use,
but also very appropriate.  One example of an input measure is the percent
increase in use of a cleaner solvent.  This could be tracked by unit sales
of that technology (adjusted for overall growth of that technology

6) Finally, evaluate each particular P2 effort.  Were the right people
reached?  Was the information provided effective?  If p2 practices were not
implemented, why not?

I hope this helps!
