The World Meteorological Organization (WMO) has taken a significant step in combating climate change with the approval of the Global Greenhouse Gas Watch (G3W) implementation plan by its Executive Council. This initiative aims to enhance monitoring of heat-trapping gases driving climate change and support climate mitigation efforts.

Key Components of the G3W Implementation Plan:

Staged Approach: The implementation plan will begin with a pre-operational phase from 2024-2027, focusing on carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), the three most critical greenhouse gases influenced by human activities.

Operational Framework: G3W will integrate all space-based and surface-based observing systems, modeling, and data assimilation capabilities related to greenhouse gas monitoring, providing an operational framework for climate action.

Transparency: Monitoring activities will adhere to WMO’s Unified Data Policy, ensuring full transparency and unrestricted international exchange of Earth system data.

Collaboration: The initiative emphasizes collaboration with WMO Members, UN agencies, and international partners to mobilize resources and ensure equal access to monitoring data and resources.

Addressing Urgent Needs:

Record CO2 Concentrations: Recent data from NOAA and the Scripps Institution of Oceanography highlight the urgent need for improved monitoring. CO2 concentrations at NOAA’s Mauna Loa Atmospheric Baseline Observatory reached a peak of just under 427 parts per million in May 2024, marking the largest two-year jump in the May peak in the NOAA record.

Operational Surface-based Network and Satellites: The implementation plan includes the development of an operational surface-based network and dedicated satellites to quantify emissions accurately.

Looking Ahead:

Long-term Vision: G3W’s vision extends beyond 2032, aligning with the Paris Agreement's Enhanced Transparency Framework and supporting countries in achieving their Long-Term-Low greenhouse gas Emission Development Strategies.

Support and Oversight:

Joint Advisory Group: A joint advisory group, co-chaired by WMO Infrastructure Commission (INFCOM) and WMO Research Board, will guide the implementation of the plan, ensuring effective collaboration and involvement of external stakeholders.

Secretary-General’s Role: The WMO Secretary-General will oversee the plan's implementation, ensuring adequate support and resources within existing budgetary provisions and administrative arrangements.

Call to Action:

Expert Support: WMO members are called upon to provide expert human resources and active participation in the joint Advisory Group and other relevant teams to support G3W activities.

The Global Greenhouse Gas Watch initiative underscores WMO’s commitment to addressing climate change through enhanced monitoring, transparency, and collaboration, marking a significant milestone in global climate action.
