In 2006, the German Federal Environmental Agency (UBA) commissioned Ingenieurgesellschaft für Wissenstransfer GmbH (gewitra) in Troisdorf to carry out a study entitled "Determination of the Emission Situation of Biowaste Recovery Activities' (UFOPLAN 2006, FKZ: 206 33 326). The findings of this study were complemented by additional assessments in a follow-up study "Determination of the Emission Situation of Anaerobic Biowaste Digestion Facilities and Determination of the Emission Situation of Biowaste Recovery in Open Composting Facilities" (UFOPLAN 2009, FKZ: 3709 44 320) likewise carried out by Ingenieurgesellschaft für Wissenstransfer GmbH, Troisdorf. The results of these two studies characterize the current state of the knowledge on greenhouse gas emissions from biowaste treatment activities.
Since 2009 the Supreme Authority for the Environment, Health and Consumer Protection (LUGV) of the state of Brandenburg has commissioned Dr. Reinhold & Kollegen, Potsdam with two studies aimed at exploring potential for reducing greenhouse gas emissions from open windrow composting facilities. For this purpose, comprehensive investigations were performed at RAL-certified composting facilities in cooperation withGütegemeinschaft Kompost and in coordination with projects performed in parallel onbehalf of the German Federal Environmental Agency. The results of these investigations and initial conclusions have been consolidated into recommendations for the Limitation of greenhouse gas emissions from open windrow composting facilities. It was concluded that the determination of the moist apparent density - which lends it self to field measurement methods - is a suitable approach to controlling the substrate compositionin such a way as to support low-emission aerobic windrow composting accordingto good management practice. To this end, orientation values were proposed for the moist apparent raw density of the input materials at the time of their windrowing. In addition, initial proposals were submitted for aeration-representative residual gas (nitrogen) levels in the substrate pores. The application of these field measurement methods in addition to continuous temperature monitoring which is already standard practice can be recommended. In this way, low-emission performance of open windrow composting facilities similar to that of enclosed facilities can be achieved.

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)

In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.
Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
