The Methane Alert and Response System (MARS) is a brand new initiative to scale up world efforts to detect and act on main emissions sources in a clear method and speed up implementation of the International Methane Pledge.
Methane launched by human actions is chargeable for round 25% of anthropogenic local weather change.
MARS will alert governments, firms and operators about massive methane sources to foster fast mitigation motion of this potent gasoline.

Sharm El Sheikh, 11 November 2022 – As a part of world efforts to sluggish local weather change by tackling methane, the UN in the present day introduced a brand new satellite-based system to detect emissions of the local weather warming gasoline and permit governments and companies to reply.

The Methane Alert and Response System (MARS), launched on the twenty seventh United Nations Local weather Change Convention, is a data-to-action platform arrange as a part of the UNEP Worldwide Methane Emissions Observatory (IMEO) technique to get policy-relevant knowledge into the correct arms for emissions mitigation.

Methane is a robust greenhouse gasoline, contributing at the very least 1 / 4 of in the present day’s local weather warming. In keeping with the Intergovernmental Panel on Local weather Change, we should minimize methane emissions at the very least 30% by 2030 – the objective of the International Methane Pledge – to maintain the 1.5°C temperature restrict inside attain.

Developed within the framework of the International Methane Pledge Power Pathway – with preliminary funding from the European Fee, the US Authorities, International Methane Hub, and the Bezos Earth Fund – MARS will permit UNEP to corroborate emissions reported by firms and characterize adjustments over time. MARS can be carried out with companions together with the Worldwide Power Company, and the UNEP-hosted Local weather and Clear Air Coalition.

“As UNEP’s Emissions Hole Report confirmed earlier than this local weather summit, the world is way off monitor on efforts to restrict world warming to 1.5°C,” stated Inger Andersen, Govt Director of UNEP. “Decreasing methane emissions could make a giant and fast distinction, as this gasoline leaves the environment far faster than carbon dioxide. The Methane Alert and Response System is a giant step in serving to governments and corporations ship on this vital short-term local weather objective.”

Along with supporting MARS, the International Methane Hub and the Bezos Earth Fund are offering funding for different UNEP IMEO actions. These embody baseline research and preliminary work on agricultural methane emissions, the place integrating multi-scale floor measurements with rising satellite tv for pc capability is anticipated to offer improved quantification.

First public world system connecting methane detection to notification processes

MARS would be the first publicly out there world system able to transparently connecting methane detection to notification processes. It’ll use state-of-the-art satellite tv for pc knowledge to establish main emission occasions, notify related stakeholders, and help and monitor mitigation progress.

Starting with very massive level sources from the power sector, MARS will combine knowledge from the quickly increasing system of methane-detecting satellites to incorporate lower-emitting space sources and extra frequent detection. Information on coal, waste, livestock and rice can be added progressively to MARS to help International Methane Pledge implementation.

“Reducing methane is the quickest alternative to cut back warming and maintain 1.5°C inside attain, and this new alert and response system goes to be a essential software for serving to all of us ship on the International Methane Pledge,” stated John Kerry, U.S. Particular Presidential Envoy for Local weather.

Elements of the Methane Alert and Response System 

MARS will use knowledge from world mapping satellites to establish very massive methane plumes and methane scorching spots and knowledge from high-resolution satellites to then attribute the emissions to a particular supply. UNEP will then notify governments and corporations in regards to the emissions, both immediately or by way of companions, in order that the accountable entity can take acceptable motion.  

If requested, MARS companions will present technical or advisory companies akin to assist in assessing mitigation alternatives. UNEP will proceed to observe the occasion location and make the info and evaluation out there to the general public between 45 and 75 days after detection.

“We’re seeing methane emissions enhance at an accelerated price. With this initiative, armed with higher knowledge and transparency, firms and governments could make higher strides to cut back methane emissions and civil society can maintain them accountable to their guarantees,” stated Dr. Kelly Levin, Chief of Science, Information and Programs Change on the Bezos Earth Fund.

“The science is evident. We have to cut back world methane emissions by at the very least 30 per cent by 2030, to maintain 1.5°C alive. Luckily, motion on methane emissions are probably the most price efficient and impactful motion a rustic can take,” stated Marcelo Mena, CEO International Methane Hub and continued “Due to this fact International Methane Hub is happy to accomplice with UNEP and the Bezos Earth Fund, on offering essential assets – to the MARS initiative – that may allow the identification and fast response to main methane emissions from the power sector, in addition to take the primary steps in enabling satellite tv for pc observations to handle methane emissions from the agricultural sector.”

“To maintain the worldwide temperature rise restricted to 1.5 levels, it’s essential that we deal with methane emissions. These emissions typically peak in particular areas for restricted quantities of time, for instance within the power sector as a result of leaks, venting, and flaring. Early detection of those peaks makes it potential to reply sooner,” Frans Timmermans, Govt Vice President of the European Fee. “The Methane Alert and Response System does simply that. Due to funding and free satellite tv for pc knowledge from Copernicus, the European Union’s Earth Remark programme, the system will allow each nation to take fast motion to cut back methane emissions.”

“The Methane Alert and Response System is a vital new software to assist pinpoint main methane leaks,” stated Fatih Birol, Govt Director of the Worldwide Power Company. “As IEA evaluation has highlighted, transparency is a crucial a part of the answer to deal with the methane downside, and this new system will assist producers detect leaks and cease them at once if and after they happen.”



In regards to the UN Setting Programme

The UN Setting Programme is the main world voice on the setting. It supplies management and encourages partnership in caring for the setting by inspiring, informing and enabling nations and peoples to enhance their high quality of life with out compromising that of future generations.

UNEP is on the forefront of methane emissions discount according to the Paris Settlement objective of maintaining world temperature rise effectively beneath 2°C. UNEP’s work revolves round two pillars: knowledge and coverage. UNEP helps firms and governments throughout the globe to make use of its distinctive world database of empirically verified methane emissions to focus on strategic mitigation actions and help science-based coverage choices by way of the Worldwide Methane Emissions Observatory (IMEO). UNEP additionally fosters high-level commitments by way of advocacy work and helps nations to implement measures that cut back methane emissions by way of the Local weather and Clear Air Coalition (CCAC). Each initiatives are core implementers of the International Methane Pledge.
