The amount of CO2 embedded in trade has substantially increased over the last decades. We study the trends and some drivers of the carbon content of trade over the period 1995-2009. Our main findings are the following. First, the mix of traded goods tends to have higher emission intensity than...

The loss of international competitiveness of domestic industries remains a key obstacle to the implementation of effective carbon prices in a world without harmonized climate policies. We analyze countries' non-cooperative choices of emissions taxes under imperfect competition and mobile...

We develop a multi-sector structural trade model with emissions from production and a con- stant elasticity of fossil fuel supply function to simulate the consequences of unilateral withdrawals from the Paris Agreement. Taking into account both direct and leakage effects, we find that a US...

Policy makers in the EU and elsewhere are concerned that unilateral carbon pricing induces carbon leakage through relocation of emission-intensive and trade-exposed industries to other regions. A common measure to mitigate such leakage is to combine an emission trading system (ETS) with...

Countries with ambitious climate targets are concerned about carbon leakage to countries with more lenient or no carbon pricing. A common policy measure against leakage is output-based allocation of emissions allowances, whose effectiveness could be further enhanced by consumption taxes levied...

This paper investigates the role of firm heterogeneity in environmentally extended new trade models, contrasting Eaton-Kortum and Melitz models to Armington and Krugman models. We show that when emissions per sales are constant across firms -- a standard assumption in the literature -- all four...

International trade is highly imbalanced both in terms of values and in terms of embodied carbon emissions. We show that the persistent current value trade imbalance patterns contribute to a higher level of global emissions compared to a world of balanced international trade. Specifically, we...
