As the result, questionnaires from municipalities and statistical projections for Germany for the year 2016 were checked. The project has shown a declining trend since 1990. On the basis of expert judgement, a further reduction of emissions in the future is expected. |

In 2020 and 2021, an additional 70 percent decrease was modeled due to cancellations for pandemic response (but no complete cancellation in Germany because there were exceptions and follow-up events). For 2022 no restrictions were modelled, only the known slight decreasing trend. |
