Regenerative Energie
Chewing gum litter is nearly everywhere in open public areas. Despite this it is commonly found stuck underneath benches, tables, handrails and escalators. Also it fi nds his way onto the surfaces of public streets and squares - a sticky waste with the consequence of expensive cleaning effort.
Chewing gum is not water soluble and unlike other confectionery it is not fully consumed. It isextremely difficult and expensive to remove once 'walked in†and dried. Gum strongly bonds to asphalt and rubber shoe soles because they are based on polymeric hydrocarbons. It also bonds strongly with concrete paving. Removal is generally achieved by steam jet and scraper but the process is slow and labor-intensive.The consumption of chewing gums in Germany amounts around 14.000 tons per year. The biggest group of consumers is in the age between 20 and 29 years. In a study (2013) of the University in Gießen, Germany, the problem of chewing gum disposal was researched. Various selected squares were analyzed and the numbers of existing as well as newly added chewing gum stains were counted.

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.
