CH4 emissions from oil and gas production in RomaniarnrnEmissions of the greenhouse gas methane CH4 are a major contributor to Europes greenhouse gas emissions and global warming impact. During COP26 in Glasgow more than a hundred countries joined the global methane pledge, which aims to reduce global methane emissions by 30 in 2030 relative to 2020 levels. Mitigation of fossil fuel-related methane leakage plays a large role in this pledge as its emissions are mostly unintentional in the first place and their reductions can even be economically profitable. However, effective emission reduction can only be achieved if sources are properly quantified and mitigation efforts are verified. Unfortunately, there are significant discrepancies between official inventories of emissions bottom-up estimates and emissions derived from direct atmospheric measurements top down estimates. rnThe Romanian Methane Emission from Oil amp; Gas ROMEO measurement campaigns carried out in 2019 phase A and 2021 phase B, respectively, aimed to investigate CH4 emissions from oil and gas production in Romania, a region with widespread oil and gas reservoirs and large reported CH4 emissions. Vehicle- and drone based measurement platforms and several emission quantification methods Tracer release, Gaussian Plume, OTM-33A, and bagging and chamber techniques were deployed on the ground across more than 400 individual production sites in the Romanian Plain and the Transylvanian Basin. Ground-based quantifications show a wide range of emissions from individual installations, similar to studies in other basins. In addition, aircraft flights visited numerous large production clusters for a top-down quantification. These aircraft measurements are evaluated with the help of mass balance models and 3D atmospheric models. The final aim of the project is to make a thorough comparison of bottom-up here ground-based and top-down aircraft based emission estimates. rnrn1Thomas Rckmann, 1Hossein Maazallahi, 1Malika Menoud, 1Carina van der Veen, 1Sylvia Walter, 2Huilin Chen, 2Katarina Vincovic, 2Steven van Heuven, 2Marcel de Vries, 3Charlotte Scheutz, 3Antonio Delre, 3Konstantinos Kissas, 4Arjan Hensen, 4Pim van der Bulk, 4Ilona Velzeboer, 4Hugo Denier van der Gon, 5Indy Vatteroth, 5Danut Dimitru, 5Cindy Verhoeven, 6Andreea Calcan, 6Aurel Constantin, 6Sebastian Iancu, 6Alex Nica, 6Sorin Ghemulet, 6Constantin Visoiu, 6Alexandru Pana, 6Alexandru Tudor, 6Mihai Profir, 6Alin Scarlat, 6Lucian Cusa, 6Marius Corbu, 6Sorin Vajaiac, 6Denisa Moaca, 6Vincent Edjabou, 6Alexandru Pana, 7Calin Baciu, 7Cristian Pop, Andrei Radovici, 7Horatiu Stefanie, 7Alexandru, Mereuta, 7Artur Ionescu, 8Martina Schmidt, 8Piotr Korben, 8Julia Wietzel, 9Lukas Emmenegger, 9Dominik Brunner, 9Randulph Morales, 9Bela Tuscon, 9Jonas Ravelid, 9Killian Brennan, 10Jaroslav Necki, 10Pawel Jagoda, 10Jakub Baryzel, 11Patryk Lakomiec, 12Dragos Ene, 12Razvan Doru, 12Alexandru Dandosci, 13Mackenzie Smith, 13Niall Armstrong, 14Daniel Zavala-Araiza, 14Stefan Schwietzkernrn1Institute for Marine and Atmospheric Research Utrecht, Utrecht University, the Netherlands, rn2Centre for Isotope Research, Energy and Sustainability Institute Groningen, University of Groningen, Groningen, the Netherlandsrn3Department of Environmental Engineering, Technical University of Denmark, Denmarkrn4Netherlands Organisation for Applied Scientific Research TNO, the Netherlandsrn5The Sniffers, Balen, Belgiumrn6INCAS, National Institute for Aerospace Research Elie Carafoli, Bucharest, Romaniarn7Faculty of Environmental Science and Engineering, Babes-Bolyai University, Cluj-Napoca, Romaniarn8 Institute of Environmental Physics, Heidelberg University, Heidelberg, Germanyrn9 Swiss Federal Laboratories for Materials Science and Technology, Empa, Dbendorf, Switzerlandrn10 Faculty of Physics and Applied Computer Science, AGH - University of Science and Technology, Krakw, Polandrn11 Department of Physical Geography and Ecosystem Science, Lund University, Lund, Swedenrn12INOE, Bucharest, Romaniarn13Scientific Aviation, Boulder, CO, USArn14Environmental Defense Fund, Netherlands and Germany rn rnrnrn
