Although a global cap-and-trade system is seen by many researchers as the most cost-efficient solution to reduce greenhouse gas emissions, developing countries governments refuse to enter into such a system in the short term. Hence, many scholars and stakeholders, including the European...

Nearly all the macroeconomic literature on environmental policies deals with taxes and tradable permits. A policy instrument that still needs to be looked at is a switch in government expenditure away from environmentally-damaging goods, in particular fossil fuels, and toward resource- and...

The Kyoto Protocol on climate change allocates tradable quotas to developed countries, but let them free to choose the means to respect their quota. There are good reasons for a country not to control its firms through internationally tradable permits. We thus compare a tax and purely domestic...

There is a tendency among policy-makers and industry lobbyists toward "specific", "relative" or "output-based" quotas, i.e., freely distributed to firms proportionally to their output. With a stochastic analytical model, we demonstrate that relative quotas are dominated either by absolute quotas...

Political attention has increasingly focused on limiting warming to 2°C. However, to date the only mitigation commitments accompanying this target are the so-called Copenhagen pledges, and these pledges appear to be inconsistent with the 2°C objective. Diverging opinions on whether this...

The scientific community is now developing a new set of scenarios, referred to as Shared Socio-economic Pathways (SSPs) to replace the SRES scenarios. To be used to investigate adaptation and mitigation, SSPs need to be contrasted along two axes: challenges to mitigation, and challenges to...

This paper covers three policy-relevant aspects of the carbon content of electricity that are well established among integrated assessment models but under-discussed in the policy debate. First, climate stabilization at any level from 2°C to 3°C requires electricity to be almost carbon-free...

This article constitutes a new contribution to the analysis of overlapping instruments to cover the same emission sources. Using both an analytical and a numerical model, we show that when the risk that the CO2 price drops to zero and the political unavailability of a CO2 tax (at least in the...

We develop a stochastic model to rank different policies (tax, fixed cap and relative cap) according to their expected total social costs. Three types of uncertainties are taken into account: uncertainty about abatement costs, business-as-usual (BAU) emissions and future economic output (the two...
