This article starts with a review of climate policy targets (temperature, concentrations and emissions for individual regions as well as the world as a whole). A 20-40% reduction target for the EU is proposed for the period 2000-2020. It then looks at costs to meet such targets, and concludes...

We review the total allocations under the EU ETS first phase and compare these against historical emissions, projections, and national Kyoto targets. We conclude that most Phase 1 allocations are excessive on all these measures, particularly the last, and argue that this is potentially damaging...

Haraden's model for estimating the economic cost of global warming is analysed. We change his method of discounting and some of his input parameters in a manner consistent with physical and economic theory as well as empirical data. We then find much higher costs than Haraden found. These costs...

In this paper, we aim to assess households' vulnerability to food-price increases in four countries in sub-Saharan Africa. We use two established indicators of sensitivity to food price changes - one measuring the share of income spent on food, the other measuring net sales of food compared to...
