Regenerative Energie
Utilization of alternative fuels in the power generating industry, in the cement industry and in the steel making industry has recently gained a considerable importance.
This is so for two reasons. Firstly, the alternative fuels are substantially cheaper than the primary ones and therefore there are potential economical gains at stake. The cement industry is here a good example since there are already a number of industrial plans operating at substantially reduced fuel costs. Secondly, the requirement to reduce emissions of the greenhouse gases has become the most important environmental concern. Recently introduced CO2 emission trading schemes are to institute a market mechanism for promoting environmentally friendly technologies. Thus, it is clear that utilization of alternative fuels in the European industry and perhaps even worldwide will increase in the years to come.
Alternative fuels offer a route to reduce the CO2 emissions through co-firing. Wood, straw or generally biomass are already co-fired with coal, in relatively small amounts, in a number of power stations. Dried municipal sewage sludge is another alternative. In Germany 24 million tons of municipal waste and around 5 million tons of hazardous waste must be disposed. Currently around 50 % of municipal solid waste is still landfilled without treatment and according to the forthcoming legislation this practise will not be allowed any more. It is expected that the production of so called Refuse Derived Fuels (RDF) which are products of mechanical-biological treatment of municipal solid wastes, will substantially increase. These RDFs can be co-fired with primary fuels in industrial boilers and furnaces.

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.
