Short summary

Estimating emissions of greenhouse gases such as methane for individual countries is fundamental for climate mitigation policies. We use a numerical weather model to simulate how methane emissions are transported to observation sites. Based on the observations, we estimate the emissions in Central Europe in 2021. For Germany and the Benelux, we find higher emissions than expected from the national emission reporting. We provide sector-specific estimates to support national emission reporting.
