Malaysia's continued extraction and use of its oil and gas resources could emit around 4bn t of greenhouse gases (GHGs), according to a report by the Helsinki-based Centre for Research on Energy and Clean Air (CREA).
Malaysia holds about 9.84bn bl of oil equivalent (boe) in committed fossil fuel reserves, of which 82pc is gas, stated the report, which was written in collaboration with environmental think-tank RimbaWatch. This figure only includes projects with proven reserves that are covered by a production commitment such as production sharing contracts.
These committed reserves would also emit an estimated 4.15bn t of CO2 equivalent (CO2e), which is equivalent to 13 years of Malaysia's annual emissions. The emissions will also consist of 10.9mn t of methane, which is a much more potent GHG than CO2.
Malaysia's remaining commercially recoverable reserves are estimated at over 17bn boe over more than 400 fields, with gas comprising about 75pc of this.
Malaysia launched its national energy transition roadmap (NETR) in 2023, detailing initiatives to achieve its 2050 net zero carbon emissions target, such as renewable energy development, hydrogen and carbon capture, utilisation and storage (CCUS). The country aims to reduce its economy-wide carbon emissions by 45pc in 2030 compared with 2005 levels, under its nationally determined contribution — climate plan — to meet the goal of the Paris Agreement.
But at the same time, the country is seeking to maximise its fossil fuel production to ensure energy security. State-owned Petronas raised its total oil and gas production in 2024 to 2.4mn b/d of oil equivalent (boe/d), up by 1pc on the year. Of this, oil production fell by 4.4pc on the year to 813,000 boe/d, while gas output rose by 3.6pc to 1.64mn boe/d.
More than 80pc of Malaysia's power was generated from fossil fuels in 2024. The NETR plans to increase the share of gas in total primary energy supply by 16pc from 2023 to 57pc in 2050, with gas viewed as a transition fuel for decarbonisation. But "referring to gas as sustainable, and claiming that Malaysia can achieve net-zero emissions through growing gas, are oxymorons," stated the report.
Petronas' Scope 1 and 2 greenhouse gas emissions totalled 46.04mn t of CO2e across its Malaysian operations in 2024, surpassing its target of 49.5mn t of CO2e for the year. In comparison, the firm recorded 45.6mn t of Scope 1 and 2 GHG emissions in 2023.
But the firm's net zero pathway excludes its Scope 3 emissions, which make up about 80pc of a fossil fuel entity's emissions, according to the report. Additionally, its CCUS plans are aimed at enabling sour gas extraction, hence exacerbating fossil fuel production and emissions.
Malaysia should instead set a sectoral carbon budget for the domestic energy sector in line with its net zero goals, taking into account both production and consumption, and cement this budget in the country's upcoming Climate Change bill, stated the report.
