22.Determination of greenhouse gas emissions from the transport of CO2 by pipelines for geological storage in a storage site permitted under Directive 2009/31/EC

B.Quantification methodologies for CO2

B.2.Method B

B.2.2.Emissions from leakage events

The operator of a transport network shall provide evidence of the network integrity by using representative (spatial and time-related) temperature and pressure data. Where the data indicates that a leakage has occurred, the operator shall calculate the amount of CO2 leaked with a suitable methodology documented in the monitoring plan, based on industry best practice guidelines, including by use of the differences in temperature and pressure data compared to integrity related average pressure and temperature values.
