* Cepsa reports annually in its Carbon Footprint following ISO 14064, GHG emissions from HFCs fugitive. CH4 and N2O, here shown, are not direct measures (except for venting), just are mathematically calculated according upstream and downstream methodology. Both methodologies are certified under ISO 14064.

* These data can slightly differ from other E&P reports to IOGP. 1 Venting emissions only include the Thailand asset.
