Maaz Maps: a science-based startup to accelerate and support the global methane pledge

<p>Acting on the significant contribution of methane to climate change, the global methane emission reduction pledge was launched at the 2021 United Nations Climate Change Conference (COP26) and has been signed by more than 100 countries. The majority of anthropogenic methane emissions have been spewed from the energy, waste and agriculture sectors which can be measured with source-specific choice of instruments, measurement platforms and evaluation methods to feed mitigation plans. Maaz Maps (www.maazmaps.com), with more than a decade of experience in methane emission studies, aims to support the global methane pledge with international collaborations by bridging between academia and industry to fill gaps and accelerate the global methane emission reduction efforts. Currently this startup is contracted by GERG (The European Gas Research Group) to scientifically evaluate methane emission reports from several technology providers: results of a measurement campaign performed at a compressor station will be shown. In this campaign, the technology providers applied bottom-up and top-down quantification methods using in-situ or remote sensing techniques. The instruments were either directly operated by walking individuals or installed on various platforms: helicopter, cars, tripods, drones, truck or poles. Various quantification methods including mass balance, tracer method and inverse modelling, correlation factors were applied to quantify sources. In this presentation, we are going to introduce the startup and reconciliation overview of the bottom-up and top-down quantification methods from the campaign.&#160;</p>
