Supporting the monitoring and tracking of carbon dioxide and methane emissions with satellites — •Dominik Brunner¹, Gerrit Kuhlmann¹, and Yasjka Meijer² — ¹Empa, Dübendorf, Switzerland — ²European Space Agency (ESA), Noordwijk, the Netherlands

Achieving the goals of the Paris Agreement to limit global warming to no more than 2°C above pre-industrial levels requires drastic cuts to emissions of carbon dioxide (CO2) and methane (CH4). The Enhanced Transparency Framework of the Paris Agreement requires all countries to provide transparent information on the implementation and achievement of their national mitigation objectives. The atmospheric community supports this process by providing independent emission monitoring based on atmospheric concentration measurements from ground and space. The European Copernicus CO2 Monitoring mission, CO2M, will be a constellation of three satellites to be launched from 2027, is designed to greatly enhance our capabilities to quantify CO2 and CH4 emissions from industrial sources, cities and countries. In this presentation, we will provide an overview of the CO2M mission, explain how CO2 and CH4 will be retrieved from spectral radiance measurements, and show its complementarity to other observations. We will present examples of how CO2M contributes to quantifying emissions, outline the atmospheric modelling frameworks that will assimilate its observations, and present a long-term perspective of how CO2M together with other observations will support policymakers in reaching the goals of the Paris Agreement.
