Current analyses of pathways limiting global warming to well below 2°C, as called for in the Paris Agreement, do not consider the climate impacts already occurring below 2°C. Here we show that accounting for these damages significantly increases the near-term ambition of transformation...

Economists argue that land rent taxation is an ideal form of taxation as it causes no deadweight losses and has therefore no adverse effects on growth. Nevertheless, pure land rent taxation is rarely applied and, if so, revenues collected remain rather small. Property taxes share some of the...

The stabilisation of GHG atmospheric concentrations at levels expected to prevent dangerous climate change has become an important, global, long-term objective. It is therefore crucial to identify a cost-effective way to achieve this objective. In this paper we use WITCH, a hybrid...

It is widely recognized that technological change has the potential to reduce GHG emissions without compromising economic growth; hence, any better understanding of the process of technological innovation is likely to increase our knowledge of mitigation possibilities and costs. This paper...

WITCH – World Induced Technical Change Hybrid – is a regionally disaggregated hard-link hybrid global model with a neoclassical optimal growth structure (top-down) and a detailed energy input component (bottom-up). The model endogenously accounts for technological change, both through learning...
