A31L - Verification of Anthropogenic Emissions and Their Role in the Earth System: Insights from Observations and Modeling II Poster

Global environmental challenges are progressively being mitigated through international collaboration, exemplified by treaties and agreements. Accurately estimating emissions of critical substances—such as methane or synthetic ozone-depleting substances—and modelling their impact on the Earth system provides a scientific basis for international regulatory policymaking and compliance negotiations. This session invites contributions addressing: (1) quantification and verification of anthropogenic emissions from various sources, including direct fugitive emissions, production- and feedstock-related processes, banked emissions, and emissions from on-site “super-emitters”; (2) exploring the role of these emissions in the Earth system using climate model simulations; (3) advances in reconciling discrepancies between “top-down”, observation-based emission assessments and “bottom-up”, process-based inventories, including enhanced monitoring (e.g., measurements in under-reported or under-sampled regions), improvements in inventory compilation through region-specific data, and activities related to measurement, monitoring, reporting and verification (MMRV); and (4) implications for control strategies and international compliance informed by these emission studies.
