BP PLC

All operated upstream assets report methane

(CH 4) emissions on a 100% basis, including

emissions from operated upstream oil and gas

and also includes terminals and LNG facilities.

Marketed gas production: all upstream gas

reaching a market from bp-operated upstream

assets, whether or not this is bp-owned product,

and includes gas production from natural gas

wells and associated gas from oil production

wells. Throughput from bp-operated oil and gas

terminals is excluded to avoid double counting

despite their associated CH 4 emissions being

included in the metric. CH 4 data is required to be

submitted into the bp group reporting tool,

OneCSR, in accordance with OMS requirements,

broadly based on the GHG Protocol Corporate

Standard and the Ipieca Petroleum Industry

Guidelines for Reporting Greenhouse Gas

Emissions 2nd Edition, May 2011. The

responsibility for quantifying and submitting CH 4

emissions for reporting is assigned to individual

bp facilities and business departments (RUs).
