Global and Regional Methane Emissions

Methane emissions are alarmingly high globally, largely from the oil and gas sector.
The top 10 methane-emitting countries account for nearly all fossil fuel-related emissions.
In ASEAN, Indonesia, Malaysia, and Thailand account for 85% of total methane emissions.
Upstream oil and gas activities are major sources of methane emissions.
Data shows significant hotspots and challenges in monitoring and reporting within the region.

Regulatory and Policy Frameworks

Only five ASEAN countries have regulations targeting methane emissions, leaving others unregulated.
Policies in Indonesia, Malaysia, Thailand, and Viet Nam focus on flaring reduction, LDAR programs, and measurement standards.
National Oil Companies are implementing methane management policies and joining international initiatives like OGMP 2.0.
Prioritizing methane reduction requires policy alignment with national and international commitments.

Methane Emission Mitigation Technologies and Practices

Detection, measurement, and abatement technologies are advancing.
Technologies range from satellite monitoring to leak detection systems with varying effectiveness.
Regulatory frameworks and cost-effectiveness drive adoption, but barriers such as high costs and technical limitations persist.
State-owned enterprises are implementing robust methane reduction strategies, leveraging technologies for better emission control.

Barriers and Challenges

Inconsistent regional policies and strategies hinder widespread mitigation efforts.
Financial constraints and lack of incentives limit investment in emission reduction technologies.
Technology barriers include scalability issues, operational complexities, data inaccuracies, and infrastructure limitations.
ASEAN's archipelagic geography compounds monitoring and control challenges.

Regional Cooperation on Methane Emissions

The ASEAN Energy Sector Methane Roundtable facilitates knowledge sharing and best practice adoption.
The ASEAN Energy Sector Methane Leadership Program focuses on capacity building and policy alignment.
The Methane Abatement Towards Sustainable Petroleum Industry (MAESTRO) project aims to develop region-specific mitigation strategies.
The proposed "Hub for Innovative and Harmonised Methane Emission Mitigation" is designed to enhance regional collaboration.
