GHG emissions data are calculated based on the American Petroleum Institute (API) Compendium (2009) and the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report as quantification references. PETRONAS aims to enhance its quantification methods to better align with national reporting requirements, taking into account the significant emissions within the region.
Notes:
-
Covers both Malaysia and international operations.
-
PETRONAS acquired BRB International B.V. and Perstorp Holding AB in 2022. Their GHG accounting systems are currently undergoing an alignment process with PETRONAS' GHG accounting and reporting requirements. The figures above do not include emissions from BRB and Perstorp, which was 0.39 million tonnes CO2e for 2024.
-
Corporate and Others include KLCC Group of Companies.

Notes:
-
Numerator for GHG intensity is a summation of Scope 1 and Scope 2 GHG emissions under the operational control approach. All GHG intensity figures include carbon dioxide, methane and nitrous oxide emissions expressed in total tonnes CO2e.
-
Boundary for Downstream GHG Intensity is Malaysia operations only.
A barrel of oil equivalent (BOE) is a unit of energy measurement used to standardise and compare the energy content of different energy sources, such as oil, natural gas and coal, by equating them to the energy contained in one barrel of crude oil.
