Risk Assessment of old Deposits – Practical Experiences

Former waste disposal sites (FWS) are a widespread problem. Unknown risk potentials and the lack of documentation leads to restrictions in the regional planning.

Currently there are 91,722 suspected waste disposal sites registered in Germany.

As a result of an enormous increase of waste mass and volume between 1950 and 1980 (doubling of household waste volume between 1950 and 1960 in Germany!) and the lack of both environmental awareness and suitable treatment methods at this era, waste was mainly dumped in the landscapes at the peripheries. Typical sites that were used for waste disposal were crater, gravel-/sandpits, trenches, (dried) channels and any kinds of natural hollows or pits. Almost all sites are characterized by uncontrolled and undocumented waste dumping without compaction, the lack of lining or securing systems and the long term substance emissions into atmosphere, soil and groundwater.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens - ein Rechtsvergleich
© Lexxion Verlagsgesellschaft mbH (8/2024)
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.
