COP30 | Belém, Brazil | November 2025
Methane Monitoring at COP30: Keeping the Momentum
Methane monitoring at COP30 put the same question to industry, government, and investors in Belém that has shaped every climate summit since Glasgow: are emissions actually going down? Two satellite launches, a landmark partnership with Petrobras, and recognition from the Canadian government made GHGSat’s presence in Belém one of the most substantive in the company’s history.
What methane monitoring at COP30 revealed
GHGSat satellites detected 652 MtCO₂e of methane between COP29 and COP30—a 37% increase from the same period in 2024, equivalent to the annual emissions from more than 152 million cars. Oil and gas accounted for 49% of detected emissions. Waste accounted for 31%.
Current government pledges under the Global Methane Pledge point to an 8% reduction by 2030. Full implementation of available technologies could deliver 32%. Before COP30, the UN reported that almost 90% of satellite-detected methane leaks flagged to governments and operators were not being acknowledged. The gap between ambition and action is as much a data problem as a policy problem.Voluntary pledges carry weight only when verified. That is the function satellite methane monitoring serves.
GHGSat at COP30: Announcements and Activity
Two new satellites launched during COP30
GHGSat launched Teodor (C-14) and Laila (C-15) aboard SpaceX Transporter-15 on November 28, 2025, bringing the constellation to 16 satellites. As world leaders committed to methane reduction frameworks in Belém, GHGSat added the infrastructure to verify them.
Petrobras partnership announced
GHGSat announced a three-way partnership with Petrobras and MAVIPE Space Systems to monitor methane across Petrobras offshore and onshore operations in Brazil. Between 2015 and 2024, Petrobras reduced upstream methane emissions by 69%. This partnership extends that record with continuous, facility-level satellite data.
Named in Canada’s national climate strategy
Canada’s Minister of Environment and Climate Change cited GHGSat at COP30 as a leader in satellite emissions monitoring, describing the company as part of a global methane data revolution.

Maintaining Momentum for the Global Methane Pledge
Methane reduction has emerged as one of the fastest, most cost-effective levers to slow global warming. Today, as Canada takes the mantle as a co-convener of the 150-country-strong Global Methane Pledge collaboration, the challenge now lies in moving from commitments to measurable results. This panel will explore what’s next for the Pledge in today’s shifting geopolitical context and highlight how leaders across the government and the private sector are driving progress through policy, international cooperation, and innovation.

Transformer le méthane des décharges en revenus : leçons tirées de la technologie de surveillance aéroportée
En Europe, GHGSat et Veolia se sont associés pour démontrer comment la surveillance avancée des émissions atmosphériques permet d’identifier et de réduire avec précision les émissions des décharges. Avec la participation active de Suez, Séché et Paprec, leaders français de la gestion des déchets, cette campagne a permis d’obtenir des informations uniques sur l’ampleur et la répartition des émissions de méthane des décharges. Cette discussion informelle abordera l’impact de cette initiative, notamment la manière dont les nouvelles technologies de mesure peuvent guider les améliorations opérationnelles, accroître les revenus et accélérer la réalisation des objectifs climatiques. Les intervenants discuteront également des enseignements tirés qui peuvent être appliqués à d’autres pays francophones s’efforçant de mieux gérer les émissions de déchets et de respecter les engagements internationaux de réduction des émissions de méthane.

FAQ
Frequently Asked Questions
Why is methane important for climate action?
Methane traps more than 80 times the heat of carbon dioxide over a 20-year period. It is the second largest contributor to global warming after CO₂, but it dissipates from the atmosphere much faster. Near-term methane reductions deliver measurable climate benefits within years rather than decades, making it the most time-efficient lever available to policymakers and operators.
What is the Global Methane Pledge?
The Global Methane Pledge is a voluntary international commitment, signed by more than 150 countries, to collectively reduce global methane emissions by 30% by 2030 compared to 2020 levels. It was launched at COP26 in Glasgow in 2021 and remains the primary international framework for coordinated methane action across sectors.
How can satellite monitoring support the Global Methane Pledge?
Satellites provide independent, facility-level methane measurements across large areas at daily frequencies. They identify emission sources that ground-based methods and self-reported data miss, and they provide the verifiable records that national inventories, regulatory frameworks, and international accountability systems require.
What is the IMEO?
The International Methane Emissions Observatory is a UNEP-led initiative that integrates satellite data from multiple providers to monitor methane emissions globally and engage operators and governments on identified emissions. GHGSat has contributed data to the IMEO since 2020.
What did GHGSat announce at COP30?
GHGSat launched two new satellites during COP30, bringing its constellation to 16. The company announced a partnership with Petrobras and MAVIPE Space Systems to monitor methane across Brazilian energy operations. GHGSat was also named by the Canadian government as part of Canada’s national methane strategy at COP30.
