THE VNCI ENVIRONMENTAL PERFORMANCE INDICATOR
APPROACH

The reasons for Environmental Performance
Indicators (EPI)
1. Determining environmental relevance 2. Prioriti
zing environmental measures and
investments 3. Target setting 4. Benchmarking
internal and external and comparing results
with previous years 5. Communication internal and
external

System approach
production
raw materials energy
product use and disposal
regional system approach

The EPI method
Groups the impacts of emissions into the
atmosphereand or water into seven environmental
effects.
To each effect a reference chemical is assigned
Environmental Effect Reference
Chemical

• Global warming CO2
• Depletion of the ozone layer CFC-11
• Acidification SO2
• Photochemical ozone creation ethylene
• Human toxicity dichlorobenzene
• Eco toxicity dichlorobenzene
• Eutrophication PO43-

5
Method

• Destination of emission (water/air)
• Environmental effect
• Chemical component

6
Aspects of the method

• Individual chemical components can contribute
  toseveral EPIs
• Each chemical component has EPI unique
  anddestination (water/air) unique weight factors
• Each EPI has its own characteristics and
  referencechemical
• EPIs can not be added up to consolidate into
  oneperformance indicator

7
Contribution to EPI versus quantity of emissions
(EPI POCP) (from a case study)
8
Proportional contribution to EPIs (case
study) Case versus VNCI total members
POCP Photochemical ozone (smog) creation
potential ETP Eco toxicity potential ODP
Ozone depletion potential HTP Human
toxicity potential GWP100 Global warming
potential AP Acidification potential EP
Eutrophocation potential
