♦ Category: Energy

IPCC: 1B2ai - Fugitive Emissions from Fuels - Oil and Natural Gas - Oil - Venting
Sector: Industrial : Petroleum Refining and Hydrogen Production

♦ Activity: Process emissions -

♦ Greenhouse gas: Methane ( CH4 )

► Year 2017 —

● Greenhouse gas emission estimate —

Amount: 40.38 tonnes of CH4 Emitted (1,009 tonnes CO2 Eq.)
Basis: Compilation
Calculation: Compilation of Mandatory Reporting emission values for 2009; previous years emissions are estimated by scaling 2009 emissions by the amount of fuel use
Reference: ARB (2016). Technical support document on GHG inventory methodologies for the 2000-2014 inventory. See Discussion of how GHG Mandatory Reporting emissions were used to estimate previous years emission proportionally to fuel use, available at:

● Activity level used in calculations —

Basis: None
Reference: Not Applicable.

● Parameters and Constants used in calculations —

Parameter: Not applicable
Constant: Global warming potential of CH4 = 25
