Sustainability Performance Data
 

The sustainability performance data disclosure aims to inform the progress of our sustainability performance, through our consolidated overview of key sustainability data from greenhouse gas and energy, environment, safety and workforce. Disclosure of sustainability performance data is aligned with international reporting standards to allow for comparable disclosure for the benefit of our stakeholders, including:
  • Ipieca / American Petroleum Institute (API)/ International Association of Oil & Gas Producers (IOGP) Sustainability reporting guidance for the oil and gas industry 
  • Global Reporting Initiative (GRI) Standards
  • World Economic Forum's Stakeholder Capitalism Metrics

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:

  1. Covers both Malaysia and international operations.

  2. 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.

  3. Corporate and Others include KLCC Group of Companies.

  2. 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.

  2. Quantification for Category 1 emissions began in 2023 using data from 2022 onwards.

  3. Category 11 only includes emissions associated with fuel products sold to third parties. All fuel products sold are assumed to be fully combusted.

  4. Scope 3 (Category 11: Use of Sold products) emissions for 2019-2023 have been restated following external GHG verification conducted by LRQA Inspection Malaysia Sdn Bhd

Notes:

  1. The increase in freshwater withdrawal by 4 per cent from 79.2 to 82.6 mil m3 is due to an increase in industrial activity by the Pengerang Integrated Complex

  2. Nitrogen oxide emissions decreased to 92,017 tonnes in 2024 from 101,695 tonnes in 2023 mainly due to lower fuel gas consumption from our maritime operations.

  3. The increase in number of hydrocarbon spills over one barrel is due to factors involving operational handling, connection issues and breaches in secondary containment.

  4. The increase in waste disposal is attributed to the host country's requirements and the limited 3R facilities in the selected international operations.
