Landfill science has shown a significant shift from a strong emphasis on isolation technologies towards obtaining a fundamental understanding of processes occurring in landfill bodies. One of the main reasons for this shift in thinking is the realization that isolation technologies alone cannot guarantee long-term protection of the environment. In addition we more and more realize that in order to have a equally prosperous society in the future it is necessary to find ways of sustainable development. The fundamental idea of sustainability is not to burden future generations with problems created by previous generations. Considering the issue of sustainable development, landfilling poses a significant challenge.
The main reason lies with the so-called contaminating life span of a landfill body (Rowe2005 Rowe (4.1.1)). The contaminating lifespan of a landfill body is defined as the period a landfill body is capable of producing emissions (both gas and liquid) in which substances are present at levels that could have an unacceptable impact on the surrounding environment. Now we realize that the contaminating lifespan of modern landfills may last for centuries (Gronow et al, 2007; Ehrig and Kruempelbeck, 2007). This is not clearly sustainable as future generations are burdened with more or less eternal aftercare of modern landfills. The current approach in some countries, where funds are provided for this eternal after-care, assume that our current day financial and regulatory institutions will survive for centuries. One can have doubts about this assumption as very few institutions have been able to survive for centuries, some examples of exceptions are the Bank of England (Gronow et al., 2007) and the Dutch Water boards which have survived over several centuries. The current approach of releasing a landfill from after-care based on monitoring data over a certain period after closure is not a sound way of assessing the risk as time alone is not the relevant parameter. Instead, knowledge of the rate of the processes responsible for stabilization of the landfill body are essential is assessing if risks of unwanted emission are low enough to consider release from (extensive) after-care (Fourie and Morris, 2003) . The increasing knowledge about the processes that occur within landfill bodies provide us with indications of the key issues controlling the contaminating life-span. Technical measures are being proposed for making landfills more sustainable. The aim of this paper is to provide a conceptual framework which gives an overview of the current state of the art in the field of sustainable land filling.

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.
