As the global food system contributes significantly to global greenhouse gas (GHG) emissions, understanding the sources of GHG emissions embodied in different components of food systems is important. The collapse of the Soviet Union triggered a massive restructuring of the domestic food systems,...

Der weltweite Klimaschutz hat im vergangenen Jahr erneut einen Rückschlag erlitten. Nach vorläufi gen Schätzungen stiegen die Emissionen von Kohlendioxid (CO2 ), dem mit weitem Abstand wichtigsten Treibhausgas, im Jahre 2005 gegenüber 2004 weltweit um etwa 2,5 %; gegenüber 1990 betrug der...

This paper explains why the approach taken so far to mitigate global climate change has failed. The central reason is an inability to enforce targets and timetables. Current proposals recommending even stricter emission limits will not help unless they are able to address the enforcement...

After the conferences in Bonn and Marrakech it is likely that international emissions trading will be realized in the near future. Major influences on the permit market are the institutional detail, the participation structure and the treatment of hot-air. Different scenarios do not only differ...

Obwohl der Emissionshandel theoretisch ein ideales umwelt- und klimapolitisches Instrument darstellt, stößt seine praktische Gestaltung und Umsetzung auf zahlreiche Schwierigkeiten. So waren bei der Einführung des europäischen Emissionshandelssystems und der Erstellung der Nationalen...
