- | 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. | + | 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.

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). | ||

As discussed on Review 2020 regarding EF used and referenced: We use different EF from different references instead the EF of Table 3-1 Tier 1 emission factors for source category 5.C.2 Small-scale waste burning, because the Tier 1 EF seem not suitable for the burning of wooden wastes. We consider both fresh wood (garden and park waste) and dry wood (without coatings etc.). We have tried to find relevant parallels, especially because of the burning of fresh wood with regard to forest fires. But regarding the EF from GB 2019 we will evaluate the use as shown in the following table: | As discussed on Review 2020 regarding EF used and referenced: We use different EF from different references instead the EF of Table 3-1 Tier 1 emission factors for source category 5.C.2 Small-scale waste burning, because the Tier 1 EF seem not suitable for the burning of wooden wastes.
