New estimates of the contribution of global food miles to total food systems emissions 1 represent an important addition to recent work in this area, for instance in relation to the food systems emissions data published in EDGAR-FOOD 2 and FAOSTAT 3 , to which the new results were compared. The food miles estimates, built on national accounts metho...
Article
The effect of the 2018 extreme meteorological conditions in Europe on methane (CH 4 ) emissions is examined using estimates from four atmospheric inversions calculated for the period 2005–2018. For most of Europe, we find no anomaly in 2018 compared to the 2005–2018 mean. However, we find a positive anomaly for the Netherlands in April, which coinc...
Article
Atmospheric nitrous oxide (N2O) contributes to global warming and stratospheric ozone depletion, so reducing uncertainty in estimates of emissions from different sources is important for climate policy. Here, we simulate atmospheric N2O using an atmospheric chemistry-transport model (ACTM), and the results are first compared with the in situ measur...
