Overview of Methane in Malaysia

While Malaysia’s total greenhouse gas emissions are dominated by carbon dioxide (1), methane represents a key opportunity for rapid and cost-effective climate mitigation. Major methane sources are concentrated in key sectors, particularly the waste (solid waste, palm oil mill effluent) and the energy sectors (including oil and gas operations). These sectors offer strong potential for near-term emission reductions in support of Malaysia’s Nationally Determined Contribution (NDC) and the National Climate Change Policy 2.0 (NCCP 2.0). However, current methane estimates rely largely on default emission factors, limiting data granularity. Variations in technical capacity across palm oil mills and challenges in monitoring fugitive emissions also hinder efforts. Overall, strengthening methane MRV systems and creating enabling conditions for reduction projects are critical to achieving Malaysia’s climate targets and its commitments under the Global Methane Pledge.

The waste sector, composed of industrial and domestic wastewater and solid waste, is the largest contributor to Malaysia’s GHG emissions and also accounts for 53% of total methane emissions. It is followed by the energy sector, composed of fugitive emissions and fuel combustion, at 37%. The agricultural and IPPU sectors each contribute 9% and 1%, respectively.

Challenges and Solutions

Malaysia faces several challenges in advancing methane mitigation, particularly in relation to data accuracy and institutional capacity. Current methane estimates rely largely on Tier 1 methodologies, limiting the robustness and granularity of emissions data. Human resource constraints also affect continuity, as technical staff turnover reduces institutional memory and consistency in data management. In addition, palm oil mills operate at varying technical and financial capacities, resulting in uneven adoption of methane capture and treatment technologies.  

Through the AKCMM Project, Malaysia is addressing these by strengthening technical capacity and improving national systems. It provides targeted technical assistance and training to upgrade methane measurement and reporting approaches, while supporting multistakeholder engagement across the energy, waste, and agriculture sectors and breaking down silos. AKCMM also supports the development of a national Methane Reduction Plan aligned with emerging climate legislation and international reporting requirements. 

The project aims to improve the accuracy and transparency of Malaysia’s methane inventory, strengthen institutional coordination, and enable scalable methane mitigation actions in priority sectors. By linking improved data systems with policy development and investment planning, AKCMM supports Malaysia’s transition toward more effective and sustained methane reduction.
