Non-UN intergovernmental agencies 

There exist also several intergovernmental agencies using space for climate action. 

CEOS 

< https://ceos.org/home-2/the-ceos-carbon-strategy-space-satellites/> In response to the Carbon Observation Strategy of the Group on Earth Observation (GEO), the CEOS Carbon Strategy for Carbon Observations from Space details the adequacy of past, present and planned satellite measurements of carbon in the land, oceans and inland waters, and atmosphere domains to support GEO. Specifically, it identifies actions that CEOS and its Agencies must take to better coordinate existing and future capabilities, as well as challenges that require additional resources and/or mandates beyond the present capacity of CEOS and its member Agencies. CEOAS also works together with the Coordination Group for Meteorological Satellites (CGMS), with whom they have jointly established the CEOS/CGMS Working Group on Climate. https://ceos.org/ourwork/workinggroups/climate/  

CEOS represents the “space arm” of the Group on Earth Observation (GEO). 

CGMS 

The Coordination Group for Meteorological Satellites (CGMS https://cgms-info.org/) coordinates long-term and sustainable satellite systems relevant to weather and climate monitoring to which both operational and research and development space agencies contribute. 

In its most recently published “Four-year High-Level Priority Plan” (2021–2025), one of the seven priorities of CGMS is focused on advancing the architecture for the space-based monitoring of climate, including greenhouse gas monitoring through the CEOS/CGMS Working Group on Climate. 

CEOS-CGMS WGC 

https://ceos.org/ourwork/workinggroups/climate/ 

The overarching goal of the Committee on Earth Observation Satellites and Coordination Group for Meteorological Satellites Working Group on Climate (CEOS-CGMS Working Group on Climate) is improving the systematic availability of climate data records through the coordinated implementation and further development of the architecture for monitoring climate from space. It has three main objectives: the first relates to an inventory of climate data records addressing the GCOS Essential Climate Variables < https://public.wmo.int/en/programmes/global-climate-observing-system/essential-climate-variables >(ECV Inventory). The second and third are addressed by a gap analysis based on the ECV Inventory and resulting in a coordinated action plan of CEOS and CGMS. 

GCOS 

The Global Climate Observing System (GCOS https://gcos.wmo.int/en/home) programme is co-sponsored by the World Meteorological Organization (WMO), the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organization (IOC-UNESCO), the United Nations Environment Programme (UNEP), and the International Science Council (ISC).  

It stimulates, encourages, coordinates and facilitates the taking of needed climate observations by national or international organizations to support their own requirements as well as common goals. It also maintains definitions of Essential Climate Variables, the observations required to meet the need to systematically observe the changing climate of the Earth. 

GFCS 

The Global Framework for Climate Services (GFCS https://gfcs.wmo.int/about-gfcs) accelerates and coordinates the technically and scientifically sound implementation of measures to improve climate-related outcomes at national, regional and global levels. GFCS enables the development and application of climate services to assist decision-making at all levels in support of addressing climate-related risks. 

Its vision is: "To enable better management of the risks of climate variability and change and adaptation to climate change, through the development and incorporation of science-based climate information and prediction into planning, policy and practice on the global, regional and national scale." 

The Global Architecture for Climate Monitoring from Space (https://public.wmo.int/en/resources/bulletin/strategy-architecture-climate-monitoring-from-space) defined in 2013 following an initiative of WMO, CEOS and CGMS, constitutes the space component of the “Observation and Monitoring” pillar of GFCS, fulfilling GCOS requirements. 

GEO 

The Group on Earth Observations (GEO https://www.earthobservations.org/index.php) is a partnership of more than 100 national governments and in excess of 100 Participating Organizations that envisions a future where decisions and actions for the benefit of humankind are informed by coordinated, comprehensive and sustained Earth observations. 

The Climate Change Working Group (CC-WG) is convened to develop and implement the GEO climate change action strategy to advance the use of Earth observation in support of climate adaptation and mitigation. It focuses on enhancing coordination of climate-related activities across the GEO Work Programme to promote an effective response to the needs of key partners such as the United Nations Framework Convention on Climate Change and IPCC, and to ensure complementarity of efforts with other data providers in the Earth observation community including WMO and the Committee on Earth Observation Satellites (CEOS). 

SCO 

The Space for Climate Observatory (https://www.spaceclimateobservatory.org ) is an international initiative launched in 2019, to gather public and private entities involved in the Earth Observation sector. SCO aims at supporting the emergence of Earth observation-based applications for climate adaptation, mitigation and monitoring at the local level, and fostering international cooperation for such projects to be shared and used in various geographic areas.
