Regenerative Energie
The main aim of the present work has been to verify if it is necessary to modify the present regulation on waste incineration plants considering more restrictive emission levels for different kinds of compounds as heavy metals. Pollutants as CrVI, Cd, As and Ni were considered as a consequence both of their emissions levels and of their carcinogenicity. The dispersion model considered as input data the guaranteed emission values for these compounds from a planned waste incineration plant in the European Union [Cocarta, 2006]. In this way it was possible to evaluate the heavy metals ground level concentrations and depositions. (Session A4: Impact of EU regulation)
Heavy metal emissions from waste-to-energy plants are inorganic compounds that could be divided in two categories as carcinogenic and non carcinogenic pollutants. With regard to the first category, the human health risk is assessed considering the multiple pathway approach, while for the non carcinogenic pollutants the human impact is assessed taken into account the reference doses. The European regulation on waste incineration plants (76/2000/EC) does not provide specific stack emission concentrations for different heavy metals as CrVI, As or Ni; these kinds of compounds are considered together with other six chemicals for which a limit of 0.5 mg Nm-3 is imposed. This paper presents an application of a multiple exposure pathways approach in order to assess the carcinogenic human health risk from a proposed waste incineration plant with a high capacity proposed in European Union. For doing this, the guaranteed concentration values of As, Cd, Ni and Cr from the proposed plant were considered. Additionally, appropriate dispersion models were taken into account in order to evaluate the heavy metals ground level concentrations and depositions. The main results underlined the importance of considering stack specific emissions limit concentrations for heavy metals as CrVI. This is a real necessity in order to avoid the overall of an acceptable individual risk equal to 10-6 as demonstrated in present paper.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens

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.
