In the past years biofuels have received increased attention since they were believed to contribute to rural development, energy security and to fight global warming. It became also clear, though, that bioenergy cannot be evaluated independently of the rest of the economy and that national and...

Biofuels and other forms of bioenergy have received increased attention in recent times: They have partly been acclaimed as an instrument to contribute to rural development, energy security and to fight global warming but have been increasingly come under attack for their potential to contribute...

CCS (carbon dioxide capture and storage) is an issue which has received increasing attention in the debate on climate change over the last several years because of its relative technical simplicity and very large potential in reducing carbon dioxide emissions. The absence of secondary benefits...

To stay within the 2êC temperature increase target for climate change calls for ambitious emission reduction targets already for the 2012-2020 compliance period. Cost-efficiency is a crucial criterion for the enforcement of such ambitious targets, requiring analyses of all possible abatement...

We investigate the socially optimal anthropogenic intervention into the global carbon cycle. The limiting factor for this intervention is the accumulation of carbon in the atmosphere, which causes global warming. We apply a simplified two-box model to incorporate aspects of the global carbon...

The paper discusses the costs and benefits to be expected by least-developed and low-income (‘vulnerable’) economies if they accede to the WTO, the impact of current debates about WTO reform on vulnerable economies, and measures to make it easier for vulnerable economies to accede to and...
