Welcome to the 1st Newsletter of the CHE project
Having officially started on 1st of October 2017 with a duration of 39 months, the CO2 Human Emissions (CHE) project is coordinating efforts towards developing a European monitoring and verification support capacity for anthropogenic CO2 emissions. This challenging target is aligned with the European Commission’s stepwise approach for a requirement-driven integration of Earth observations, from remote sensing and in situ, with enhanced modelling capabilities for CO2 fossil fuel emissions, along with other natural and anthropogenic CO2 emissions and transport. The project pursues a consolidated methodology for integrating the monitoring system components, as well as innovation for estimating fossil fuel CO2 fluxes. These include reconciling bottom-up and top-down approaches and handling systematic errors of satellite observations. Earth observations from satellites will be combined with in situ CO2 observations and information from co-emitters or isotopes to support the attribution of fossil fuel emissions and uncertainty reduction.

The CHE Structure
To tackle the challenges of an integrated support capacity on a global scale, it is paramount to identify the complementarity between observations, modelling and data assimilation methodologies by establishing their limitations and strengths. CHE will address these aspects in four work packages (WP1 - WP4) that will use existing capabilities to provide supportive datasets and assessments of the current state of affairs, while at the same time bringing innovation to the various components with an eye on overall integration in a fully comprehensive system (Scientific Layer). In addition, CHE will identify the operational aspects of all the components to ensure a realistic architecture (WP5). Together with the capacity-building aspects (WP6) and coordination (WP7), this is summarized in Figure 3, with a work breakdown structure that illustrates the seven CHE work packages interconnected and clustered in layers. The work packages are described in the next section. Read more…
The CHE Library of Simulations
One of the critical elements of a European contribution to a global "CO2 emission monitoring system" identified in the CO2 report commissioned by the European Commission is a constellation of CO2 satellites with imaging capability. Between 2011 and 2015, ESA conducted a detailed Phase A/B1 assessment for the CO2 imaging satellite concept CarbonSat (Bovensmann et al., 2010). In two science studies (LOGOFLUX-1, 2014; LOGOFLUX-2, 2015) supporting this assessment, it was demonstrated that such a satellite would allow observation of CO2 plumes of strong localized sources such as large cities and power plants and would help constrain emissions at the regional and national scale. However, such emission quantification faces substantial challenges due to the limited precision of the satellite measurements, systematic biases introduced by incompletely accounting for the effects of aerosols and other factors in the retrieval, the limited spatial and temporal coverage and resolution of the observations, and the difficulty in separating the signals from natural CO2 fluxes from those of anthropogenic emissions. To support the assessment of the requirements for a future space mission and the challenges introduced by the issues listed above, a library of realistic CO2 simulations for present-day and future emission scenarios, from the global to the regional and point-source scale is needed.

Mapping CO2 fossil fuel uncertainty representation
CO2 Human Emissions’ uncertainties, estimated by the 2006 IPCC Guidelines for National Greenhouse Gas Inventories and 2015 global emission data to be around 9-10% for countries with well-developed statistical systems, and 16-18% for countries with less-developed statistical systems, have been the focus of a meeting in Ispra (Italy), 4-5th June 2018. Being able to specify (and progressively improve) the accuracy level for fossil fuel emissions globally is essential to combine bottom-up and top-down estimates for anthropogenic CO2 Emissions in support of the Paris Climate Agreement, and it is a key study area in the CHE project (with a dedicated work-package, WP3).

First Strategic Research Agenda released
The aim of the first Strategic Research Agenda released on the 30th on June 2018 is to summarise current research activities, within and outside CHE, and to outline the future strategies required for establishing the CO2 monitoring and verification support capacity and the required capabilities. CHE will produce a clear set of outputs in reports summarizing the current state-of-affairs, including a gap analysis, providing recommendations on needed developments including first innovative steps for current systems and system integration, and the operational aspects of the various needed components.

CHE Collaborations with other H2020 projects
Monitoring CO2 emissions at the surface requires unprecedented levels of precision of measurements at global scale, involving both in-situ observing networks and space-based remote sensing, combined with models that are capable to disentangle the signal of natural and anthropogenic emissions. Between the last quarter of 2017 and first quarter of 2018, under the European Commission vision outlined by the CO2 Task Force (link to CO2 report), three Horizon 2020 projects have been approved for funding and initiated the work: CHE (CO2 Human Emissions, focusing on outlining integration requirements of observations, modelling and assimilation components for a future global monitoring and verification support capacity), VERIFY (focusing on quantifying more accurately carbon stocks and the fluxes of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) across the EU based on independent observations in support of inventories) and SCARBO (focusing on exploring new technologies to improve the space-based observations of CO2 and CH4). For the CHE project, as a H2020 Coordination and Support Action, key activities are to liaise with and contribute to other projects in the area of CO2 monitoring. As such CHE has established links with SCARBO and VERIFY, via participative interactions (e.g. at the level of expertise in each of the teams and in programmatic board meetings). Read more…
