A unilateral tax on CO2 emissions may drive up indirect carbon imports from non-committed countries, leading to carbon leakage. Using a gravity model of carbon trade, we analyze the effect of the Kyoto Protocol on the carbon content of bilateral trade. We construct a novel data set of CO2...

In a world where the prospects of a global agreement to control greenhouse gas emissions are bleak, the idea of using trade policy as an implicit regulation of foreign emission sources has gained many supporters in countries contemplating unilateral climate policies. Embodied carbon tariffs tax...

A country's optimal environmental border policy includes a strategic component that is inconsistent with commitments under the General Agreement on Tariffs and Trade (GATT). We extend the theory to include GATT compliance. Theory supports optimal border adjustments on carbon content that are...

This paper analyzes the economic and poverty effects of a voluntary carbon emission reduction for a small liberalized economy - the Philippines. The simulation results indicate that tariff reductions undertaken by the Philippine government between 1994 and 2005 reduced the cost of fossil fuels...

Carbon-based border tax adjustments (BTAs) have recently been proposed by some OECD countries to level the carbon playing field and target major emerging economies. This paper applies a multi-sector dynamic computable general equilibrium (CGE) model to estimate the impacts of the BTAs...

Carbon tariffs are one prominently discussed environmental policy. The proponents stress the carbon tariffs' ability to mitigate the potential negative effect of environmental-friendly production on competitiveness, to avoid carbon leakage and to reduce world carbon emissions. We analyze the...

After the Paris Climate Agreement, it is anticipated that carbon prices will differ across regions for some time. If countries use free allowance allocation as carbon leakage protection, only a fraction of carbon prices are passed through to consumers particularly by carbon intensive materials...

Using a model of monopolistic competition with two countries, where we allow for technological asymmetries, we examine the relationship between intra-industry trade and environmental regulation. The decisions on emission standards set by each country show strong strategic interactions. We show...

This paper assesses quantitative estimates based on economic modelling studies of the economic and environmental benefits from different forms of international co-ordination on carbon pricing. Forms of international co-ordination include: harmonising carbon prices (e.g. through linking carbon...

As the European carbon border adjustment (CBA) mechanism is high up on the European Commission's agenda and soon to be implemented, it is important to understand the economic and environmental implications of alternative designs of such a mechanism. To this end and with a view to informing the...
