The IG3IS Stakeholder consultations and User Summit


IG3IS logo

Reaching the goal of the Paris agreement requires diverse stakeholders to implementation actions on emission reduction and to facilitate sustained or increased uptake of the greenhouse gases by sinks. Recent development in science and technology allow to overcome some of the limitations of knowledge provided by the inventories and guide the most efficient action to address the causes of climate crisis. Given that emission reduction actions are occurring at different scales and across economic sectors, IG3IS aims to tailor guidance and information development in direct response to these needs. The breadth of sectors and actors requires established dialogue between the technical solution providers, the scientific community, practitioners, the non-governmental community, and decision-makers. 

To facilitate such a dialogue, WMO is hosting the IG3IS Stakeholder Consultations and User Summit on 2-3 February 2023 at WMO Headquarters in Geneva.  This event will bring together key users from several sectors to engage in conversation with the IG3IS scientific community. WMO is inviting stakeholders and users to articulate their needs for data-driven GHG emission information at multiple scales (e.g., national, urban, facility). The scientific community developing IG3IS services will present existing capabilities that can either meet information needs and/or reframe expectations and understanding of emerging scientific capabilities.

This summit will be preceded by the WMO International Greenhouse Gas Monitoring Symposium on 30 January- 1 February 2023.
