- | Emissions from open burning of wood and green waste for traditional purposes, so-called bonfires such as Easter fires, are reported model-based. In addition to biogenic carbon dioxide, emissions of NOx, SO2, CO, NMVOC, particulate matter (PM2.5, PM10 and TSP) and Polycyclic Aromatic Hydrocarbons (PAHs) are covered so far. | + | Please see chapter regarding farming/ |
