Earth observation satellites play an essential role in monitoring potent greenhouse gases (GHGs) like carbon dioxide (CO2) and methane (CH4) by providing global datasets and transparent insights that help scientists, policymakers, and organisations to track and manage emissions and removals. Different types of sensors are needed to track CO2 and CH4 emissions on different spatial scales […]
Article 14 of the Paris Climate Agreement sets out the concept of the Global Stocktake (GST) as a means to evaluate global progress towards the goals of the Agreement. Earth observations naturally play a key role in this process, and CEOS & CEOS Agencies have been working hard in the years leading up to the first GST, to be […]

Over the past 3 years, the previous Australian SIT Chair Team and current ESA SIT Chair team have been exploring avenues of collaboration between CEOS and UNEP’s International Methane Emissions Observatory (IMEO). As anticipated at the recent SIT Technical Workshop, IMEO has today launched its ground-breaking Methane Alert and Response System (MARS) at COP 27, with […]
Recognising that the rapid build up of carbon dioxide (CO2), methane (CH4) and other anthropogenic greenhouse gases (GHGs) is the primary driver of climate change, Parties to the Paris Agreement have resolved to rapidly reduce their emissions. To track progress toward this goal, Parties are compiling inventories of anthropogenic GHG emissions and removals, which are […]
Biomass, the living part of vegetation systems, plays a crucial role in climate. Around half of biomass is carbon, so when vegetation is destroyed, as in deforestation, carbon dioxide is released to the atmosphere. This is a huge source of atmospheric carbon – about 6 billion tons of carbon dioxide per year. At the same […]
Systematic observations of the Earth’s atmosphere and surface from ground-based, airborne, and space-based sensors are absolutely crucial for the characterization of Earth’s climate. They are what make the work of the UNFCCC, the IPCC and the Paris Agreement possible, and more than half of the 60 or so Essential Climate Variables – the physical, chemical, […]
