Session Proposal: Verification of Anthropogenic Emissions: Informing International Regulation and Compliance (AGU25)

A105
Verification of Anthropogenic Emissions: Informing International Regulation and Compliance

Session ID#: 248696

Session Description:
Global environmental challenges are progressively being mitigated through international collaboration, exemplified by treaties and agreements. Accurately estimating anthropogenic emissions of critical substances—such as greenhouse gases, synthetic ozone-depleting substances, and volatile chemical products—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 types of sources, including direct fugitive emissions, production- and feedstock-related processes, banked emissions, and emissions from on-site “super-emitters”; (2) 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); (3) assessments of the environmental impacts of anthropogenic emissions; and (4) implications for control strategies and international compliance informed by these emission studies. We welcome studies at local, regional, and/or global scales.
