+ | Within NFR sub-category 5.C.2 - Open Burning of Waste, the German emissions inventory provides emissions from registered bonfires and other wooden materials burnt outdoors. Emissions from bonfires are key source for PM2.5 and PM10, but in principle of minor priority due to discontinuous appearance. | ||
+ | |||
+ | Please see chapter regarding farming/ | ||
+ | |||
+ | 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. | ||

+ | |||
+ | =====Method===== | ||
+ | |||
+ | For developing of a estimation frame a survey regarding the number of such bonfires was carried out by an expert work ((Wagner & Steinmetzer, | ||
+ | |||
+ | As discussed on Review 2020 regarding all relevant sources: A comparison shows that the volume of bonfires is significantly higher than the volume of campfires. In terms of number, however, the two types of fires are similar. Due to the large fluctuations of the minimum/ | ||
+ | In our view the estimation of bonfires emissions is conservative and completly. | ||

+ | ===== Trends in emissions ===== | ||
+ | |||
+ | All trends in emissions correspond to trends of AD. No rising trends are to identify. In 2019, there were many bans on open fires due to increased forest fire danger. | ||
