Regenerative Energie
Directives and other regulations adopted by the European Union have an increasing influence on national laws and ordinances. Due to the new European directive on industrial emissions, the emission values of municipal waste incinerators are discussed in Germany. One reason is the higher relevance of the best available technique documents in the new directive.
In this connection, total emissions of nitrogen oxides generated by German municipal waste incinerators were calculated. In comparison to all industrial sectors and private households, municipal solid waste incinerators contribute only 0.8 to 1.5 % to all nitrogen oxides emissions. Highest emissions are encountered in the traffic sector and the power plant sector. It can be assumed that further decrease of emission values in waste combustion will not have any effect on the environment.
A short introduction to the technologies for reducing the nitrogen oxide emissions shows that the selective catalytic reduction technology (SCR) consumes less auxiliary chemicals and, hence, less resources than SNCR. On the other hand, the selective non-catalytic reduction technology (SNCR) has a lower energy input.
These results are of interest in the context of the criteria to be considered when determining the best available technologies. According to the directive on industrial emissions, the consumption of auxiliary chemicals and energy efficiency have to be taken into account. For an energy- and resource-efficient separation of nitrogen oxides, a trans-sectoral approach to municipal waste incineration and energy production is developed.
Nitrogen oxide emissions from municipal solid waste incinerators are further reduced by SCR systems installed at power plants in the form of a service against payment. The SCR systems at power plants do not require a reheating of the flue gases and, hence, can be run more efficiently than SCR systems at municipal solid waste incinerators. In addition, investments for a retrofit of existing municipal solid waste incinerators can be avoided.
Due to the definition of technical plants in the European directive on industrial emissions and other regulations, a trans-sectoral approach for enhanced energy and resources efficiency cannot be implemented at the moment. Future use of the trans-sectoral approach will depend on political decisions.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
