Economic theory suggests that with a pollution externality and learning spillovers related to renewable energy technologies, the optimal climate policy mix includes an emissions policy and an output subsidy to the learning industry. Instead of output subsidies, feed-in tariffs are often...

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...

We explore a global carbon pricing framework to inform the potential coordination of carbon pricing and equivalent policies. The framework has three main features aligning with the current multilateral system for climate action. First, the carbon price is determined by a global average carbon...

The European Commission’s (EC) proposed Carbon Border Adjustment Mechanism (CBAM) is meant to mirror the carbon price of the EU Emissions Trading System (EU ETS) for several imported goods. While the CBAM can rely on certain aspects of the EU ETS regarding its costs and compliance obligations,...

Carbon pricing at appropriate levels is critical in the response to climate change, but currently only a fifth of global emissions are priced. Successful carbon pricing in Asia can help jurisdictions in the region achieve their climate targets cost-effectively, spur investments into low-carbon...

A broad consensus exists that carbon pricing is key for cost-effective emission reductions and that it must play a major role in driving the transition to a climate-neutral economy. However, despite significant progress in wider climate policy uptake in recent years, the vast majority of...
