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...

The paper discusses three general classes of nonlinear programming models. Our objective is to show how to represent optimization problem, such as nonlinear programs, in a compact format using extended mathematical programming. This is a useful tool, especially in cases when complementarity...

We analyze subglobal action to mitigate climate change with a consideration of recent advances in the theory of international trade. Subglobal action impacts emissions in unconstrained countries (carbon leakage) through international trade channels. Consequently, estimates of the efficacy of...

This report investigates the environmental impacts of Russia's accession to the World Trade Organization. A 10-region, 30-sector model of the Russian economy is developed. The model is innovative and more accurate empirically in that it contains foreign direct investment, imperfectly competitive...

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...

The cost-effectiveness of unilateral emission abatement can be seriously hampered by emission leakage. We assess three widely-discussed proposals for leakage reduction targeted at energy-intensive and trade-exposed industries: border tax adjustments, output-based allocation and industry...
