2011 Annual Report - SBM Offshore

5.1.2 Environmental Reporting
Environmental performance of the 11 production and/or storage units is reported taking into account the following
reporting boundaries:
• units in the Company's fleet producing and/or storing hydrocarbons under lease and operate contracts during 2011;;
• units in which the Company exercises full operational management control;;
• units in which the Company has full ownership or participates in a Joint Venture (JV) partnership, where the Company
controls 50% or more of the shares.
Offshore Production environmental performance results are chosen according to the performance indicators
relative to GRI. This includes greenhouse gases referred to as GHG, which are N2O, CH4 and CO2, in addition to
other non-GHG air emissions, such as CO, NOx, SO2 and VOC. The air emissions calculation from the offshore
production units are performed using as the basis for the calculation the method recommended by Oil & Gas UK
(OGUK).
The Company uses the WRI Greenhouse Gas Protocol (GHG Protocol) method to calculate CO2 equivalents.
Carbon dioxide equivalency is a quantity that describes, for a given mixture and amount of greenhouse gas, the
amount of CO2 that would have the same global warming potential (GWP), when measured over a specified
timescale (generally, 100 years). For more information on the GHG protocol and country specific calculation
methods, please see their website: http://www.ghgprotocol.org/calculation-tools.
Environmental spills to air, water or land for the units are reported.
All reported air emissions exclude flaring, as this factor, related to the produced fluids from the oil/gas reservoirs,
is reported by the Company’s clients.
