Regenerative Energie
Two different methods for quantifying gaseous emissions have been used and assessed in this study. These are small scale point measurement methods and they were used at a composting facility treating garden waste: a flux chamber method and a dynamic funnel method. The present paper describes the generation of GHGs and their spatial and
temporal distribution during composting. In addition the emissions of these GHGs have been quantified and related to the degraded mass of carbon and nitrogen respectively.
The knowledge of benefits and disadvantages from composting of garden waste is limited due to a lack of scientific studies on the topic. The potential benefits are use of mature compost as a soil improver, thus saving industrial fertilisers, and the main potential disadvantage is generation and emission of greenhouse gases (GHGs). The most important GHGs are methane (CH4) and nitrous oxide (N2O) in relation to degradation of organic waste. Other gases like carbon dioxide (CO2) and carbon monoxide (CO) are also produced during composting. CO2 emissions from degradation of biogenic material (as in composting) are usually accounted as global warming neutral and the CO emissions are limited in this context. The emission of the gases is especially important from low technology composting like windrow composting, where the emission of gases are not controlled. Quantification of GHGs from degradation of organic waste is important in order to improve the understanding of the composting process. The aim is to improve model parameters over time and consequently enlarge comparability, consistency, accuracy and certainty of emission data reported to national and international databases.

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.
