Under the motto “The other half of the problem,” researchers and inventory compilers met in Utrecht from June 15–17, 2026, for the 1”0th International Symposium on Non-CO₂ Greenhouse Gases (NCGG10)”. The motto highlights the significant contributions of non-CO₂ greenhouse gases such as CH₄, N₂O, and SF₆ to global warming—and the associated challenges of advancing climate protection and mitigation measures more

The Avengers project, a Horizon Europe initiative aimed at supporting and improving GHG emission estimates, held an online workshop from 27 to 29 May and invited ITMS to take part. more

The Integrated Greenhouse Gas Monitoring System for Germany (ITMS) was represented at the 2026 EGU General Assembly in Vienna with a wide range of oral and poster presentations. In addition, several sessions were organized by ITMS members. more

ITMS was represented at the “National Forum for Remote Sensing and Copernicus” at the European Space Operations Centre (ESOC) in Darmstadt from April 28–30, 2026, where it showcased the current status of the project. more

From April 14 to 16, 2026, members of all ITMS modules (Modelling, Observations, Sources & Sinks, Utilization, and Coordination) gathered at the German Weather Service (DWD) in Offenbach for the “ITMS Joint Module Meeting”- The event aimed to present the progress of each module and to foster cross-disciplinary exchange.

In the ITMS project, a new system is being developed at the DWD to assess greenhouse gas emissions based on concentration measurements and weather modeling. Now we have published two new papers in the journal Atmospheric Chemistry and Physics, describing the ITMS-Demonstrator and estimating the Germany's methane emissions in 2021. Here, we explain the foundations of this system. more

Atmospheric measurements can complement greenhouse gas inventory methods, offering additional approaches for tracking emissions, identifying trends, and supporting transparency. A new “good practice guidance” from WMO outlines approaches for using atmospheric observations in national GHG inventories, with contributions from ITMS on national-scale GHG emission estimation in Germany. more
