• Reasons for undertaking a verification include
• to add credibility to publicly reported
  information
• to increase management and board confidence in
  reported information
• to improve internal GHG accounting and reporting
  practices
• to meet or anticipate the requirements of future
  trading programs.

IDENTIFYING SOURCES OF CO2 EMISSIONS

• AgipPetroli Refinery case study
• GHGs are mainly CO2 emissions
• Methane (CH4) and nitrous oxide (N2O)
  contributes for a no significant rate
• No other GHG emissions

1. Define clear organisational and operational
boundaries 2. Apply and compare IEA and IPCC
international conversion factors 3. Account and
Report GHGs emissions from marginal sources 4.
Identify GHG emissions from indirect source, i.e.
drilling and transport of oil (upstream),
production of input used in the oil cycle
refinery, oil products use and re-use, waste
management and recycling.
Future steps

1. There is no such thing as a universal oil
refinery they differ in size, complexity, types
of processes they operate, the crudes they
process 2. Climatic/environmental conditions and
the location can influence impact of emissions on
the environment 3. It could be necessary a site
specific content to account these differences.
Future steps

CONCLUSIONS
1. The oil refinery sector requests the
definition and development of a corporate
international and standardized methodology for
GHG accounting 2. AgipPetroli is willing to
cooperate with other companies and institutions
involved in identifying and supporting a national
and international methodology
Conclusions
