Emissions from bonfires are key source for PM2.5 and PM10, but in principle of minor priority due to discontinuous appearance.+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 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), Polycyclic Aromatic Hydrocarbons (PAHs) and Heavy Metals are covered so far.+Emissions from open burning of wood and green waste for traditional purposes, so-called bonfires such as Easter fires, are reported model-based.

-Activity data for this category are based on data from a step by step calculation: After the evaluation of the questionaires an extrapolation of the volume and the number of bonfires was made for Germany. For the years since 2019, it became visible that, in addition to the model-based continuous decrease in activities, special aspects must be taken into account: Because of the restrictions on public activities during the pandemic, modeling of less traditional events was searched for. Two types of fires were already classified in the expert project: camp fires in the more private sector and, most importantly, Easter Fires in the more public sector. The calculations are now considered separately and the camp fires are modeled with a continued steady decline. The mainly Easter fires follow an approach about general percentage decreases and additionally in 2019 five percentage points decrease corresponding to various cancels due to forest fire risk. In 2020, an additional 70 percent decrease was modeled due to cancellations for pandemic response (no complete cancellation in Germany because there were exceptions and follow-up events).+Activity data for this category are based on data from a step by step calculation: After the evaluation of the questionaires an extrapolation of the volume and the number of bonfires was made for Germany.
