Urgent Action Needed to Meet Global Methane Reduction Goals

Scientific assessments indicate that while the technical potential exists to meet a global pledge to cut methane emissions by 30% by 2030, the challenge lies in implementation. Experts, including Gabrielle Dreyfus, Thomas Röckmann, and Lena Höglund-Isaksson, emphasize the urgency of this issue as they prepare to gather in Italy to discuss the latest science and policy measures needed to address methane emissions. Despite increased mitigation ambition under national plans, the world is still falling short of the 30% reduction target.

The Global Methane Status Report reveals that human-caused methane emissions continue to rise, albeit at a slower rate than previously projected. In 2021, emissions were expected to increase by 9% between 2020 and 2030, but updated analysis suggests a 5% rise. This change is attributed to slower growth in unconventional gas production and reduced waste emissions in certain regions. Nevertheless, the current trajectory does not achieve the necessary reductions, although commitments outlined in Nationally Determined Contributions and Methane Action Plans could lead to an 8% reduction if fully implemented.

The technical potential to meet the methane reduction pledge is well-documented, with the energy sector holding the key to approximately 70% of the total reduction potential. Measures such as recovering associated petroleum gas, regular leak detection, and installing ventilation air oxidation technologies in coal mines are proven and often cost-effective. However, current commitments only achieve a fraction of the feasible reductions in this sector.

Agriculture and waste sectors also present opportunities for methane reduction. Improved water management in rice cultivation and advancements in waste management have shown promise, although long-term mitigation requires further investment in landfill improvements and circular waste systems. The expansion of methane monitoring capabilities, including satellite and ground-based sensors, enhances accountability and national inventories, although policy action should not be delayed by the need for perfect measurement.

The next two years are critical for translating existing commitments into tangible emissions reductions. Governments are urged to adopt international methane performance standards for oil and gas, supported by binding technology standards. A proposed legally binding methane agreement, starting with the oil and gas sector, could further drive progress, although political and economic dependencies on fossil fuels remain significant barriers.

The coming years will determine whether the alignment of technology, scientific evidence, and political leadership can deliver a rapid transition to near-zero methane energy systems and sustainable agricultural and waste management practices. The Global Methane Status Report highlights the beginning of a shift in course, but achieving the necessary downward trajectory will test political resolve. Scientists have provided the evidence, and it is now up to leaders to act decisively.
