Climate effects of unilateral carbon policies are undermined by carbon leakage. To counteract leakage and increase global cost-effectiveness carbon tariffs can be imposed on the emissions embodied in imports from non-regulating regions. We present a theoretical analysis on the economic...

Unilateral carbon policies are inefficient due to the fact that they generally involve emission reductions in countries with high marginal abatement costs and because they are subject to carbon leakage. In this paper, we ask whether the use of carbon tariffs—tariffs on the carbon embodied in...

The Clean Development Mechanism (CDM) established under the Kyoto Protocol allows industrialized Annex I countries to offset part of their domestic emissions by investing in emissions-reduction projects in developing non-Annex I countries. We present a novel CDM modelling framework which can be...

Dividing the burden for greenhouse gas abatement amongst the provinces has proven chal- lenging in Canada, and is a major factor contributing to Canada’s poor historic performance on greenhouse gas abatement. As the country aims to achieve substantial cuts to emissions over the next decade and...

Concerns about adverse impacts on domestic energy-intensive and trade-exposed (EITE) industries are at the fore of the political debate about unilateral climate policies. Tariffs on the carbon embod-ied in imported goods from countries without emission pricing appeal as a measure to reduce...

Embodied carbon tariffs tax the direct and indirect carbon emissions embodied in trade — an idea popularized by countries seeking to extend the reach of domestic carbon regulations. We investigate their effectiveness using simulations from an applied general equilibrium model of global trade...

We show that imposition of a state-level environmental tax in a federation crowds out preexisting federal taxes. We explain how this vertical fiscal externality can lead unilateral statelevel environmental policy to generate a welfare gain in the implementing state, at the expense of other...

The double or even triple dividend hypothesis of green tax reforms has beena major issue of dispute in both the scientific community and the politicalarena during the last decade. Theoretical analysis has provided a number ofimportant qualitative insights to the debate but lacks of actual...

Tradable black (CO2) and green (renewables) quotas gain in popularity and stringency within climate policies of many OECD countries. The overlapping regulation through both instruments, however, may have important adverse economic implications. Based on stylized theoretical analysis and...

We present a meta-regression analysis of model-based simulation studies assessing the employment effects of environmental tax reforms. Besides the role of central modeling assumptions we investigate the implications of contracting bodies on the simulation results. Our analysis reveals the...
