GHG Emissions and Reductions

Throughout 2025, MedcoEnergi has implemented a series of initiatives across its oil & gas assets specifically designed to reduce greenhouse gas (GHG) emissions. These initiatives encompass a multifaceted approach, including optimizing fuel consumption and flare reduction practices, implementing gas lift conversion strategies, and fostering the adoption of renewable energy sources.

We have maintained consistent tracking, management, and reporting of Scope 1 and Scope 2 GHG emissions. We disclosed assured Scope 3 emissions for the first time in 2024. Our standardised Air and GHG Emissions Calculation Tools comply with the latest laws and regulations and are aligned with relevant standards and frameworks. For further information on the details of GHG emissions calculation methodology, please refer to the MedcoEnergi's GRI Performance Data.

Scope 1 & 2 GHG Emissions

MedcoEnergi categorizes its GHG emissions into Scope 1, and Scope 2 in accordance with the GHG Protocol. Scope 1 emissions encompass direct emissions from our oil & gas and power assets, primarily generated through the combustion and flaring of natural gas. We are actively supporting government initiatives aimed at eliminating routine flaring by 2030. Our Scope 2 emissions account for indirect GHG emissions associated with our purchased electricity and steam.

Scope 3 GHG Emissions

Our Scope 3 GHG emissions refer to indirect emissions generated throughout our value chain, beyond our Scope 1 and Scope 2 GHG emissions. We have adopted the operational control approach for Scope 3 GHG emissions, focusing on Category 3 (Fuel- and energy-related activities), Category 10 (Processing of sold products), and Category 11 (Use of sold products). Our calculations follow the GHG Protocol and other industry standards, including guidelines from the International Petroleum Industry Environmental Conservation Association (IPIECA) and American Petroleum Institute (API) as well as emission factors from the UK Government, Intergovernmental Panel on Climate Change (IPCC), International Energy Agency (IEA) and emission intensity data from downstream value chain companies.
