What is the thing being measured? Sustainability performance of what?
Four common alternatives:
1. Supply chains
2. Industries
3. Products and services
4. Organizations (i.e., their operations or activities)

Sustainability performance of a network of organizations Can involve one or more areas of impact (e.g., GHGs) Currently the subject of at least 2 standards efforts: ◦ WBCSD/WRI Corporate Value Chain (Scope 3) standard (in public review) ◦ GRI (started in late 2010)

This is the world of LCAs!
This is GRI’s exclusive target of interest (so far) Also the GHG Protocol (Scopes 1 and 2) Carbon Disclosure Project UL 880 (when it is completed)

To normalize a measure of performance is to express performance relative to some other variable of interest
Three alternatives of interest to us today:
1. Relative normalizations (i.e., relative metrics)
2. Absolute normalizations (i.e., absolute metrics)
3. Context-based normalizations (context-based metrics)

“Relative metrics express operational performance in terms of how performance in one area (e.g., water use) correlates to performance in another area (e.g., revenue or total production) – as in water consumed per unit of revenue or water consumed per unit of production during a specific period of time.”

“Absolute metrics express operational performance in terms of what overall levels of performance are in specific areas of interest (e.g., water use) for an organization as a whole – as in the total volume of water consumed by an organization during a specific period of time.”

“Context-based metrics express organizational performance in terms of impacts on vital capitals, relative to norms or standards for what such impacts ought to be (for specific periods of time) in order to ensure stakeholder well-being (e.g., total water consumed per employee per year compared to a fair or equitable allocation of available renewable supplies).” [Actual state of the world gives rise to thresholds which act as standards of performance.]

Normalization Method
True Measure of Sustainability?
Relative Metrics
Correlated to Some Other Area of Performance
No
Absolute Metrics
Expressed for Organization as
a Whole No
Context-Based Metrics
Tied to Social and Environmental
Thresholds Yes

Relative Absolute Context-Based
Supply Chains − New GRI and GHG Protocol
−
Industries − Various ad hoc (e.g., DMI’s dairy
−
Products and Services LCA − −
Organizations − GRI EFM, SFM and CBS in General**
* Most commonly used in practice ** Ecological Footprint Method, Social Footprint
Method and Context-Based Sustainability

It is duties and obligations owed to stakeholders that determines the appropriate content and boundaries of a company’s sustainability program
Otherwise, content and boundaries are potentially arbitrary, too broad or too narrow

“A stakeholder in an organization is anyone whose vital capitals – and whose interests and well-being, therefore – are affected by the organization’s actions, or whose vital capitals ought to be so affected by virtue of the relationship that exists between them.”

Sustainability metrics focus on 4 targets of interest 3 different approaches to normalization are used Most commonly used metrics are relative and absolute
metrics…. They can support sustainability management efforts…. But only context-based metrics (CBMs) make it possible to
measure and report true sustainability performance GRI advocates for CBMs, but does not enforce it Various methods in existence since the mid-’nineties (EFM,
SFM and CBS) consist of context-based metrics Regardless of metrics used, it is stakeholder relationships
that determine the relevant areas of impact that should be measured, managed and reported in a sustainability management program
