The market for voluntary carbon offsets has grown steadily in the last decade, yet it remains a very small niche. Most emissions from business travel are still not offset. This paper exploits a unique dataset examining the decision to purchase carbon offsets at two academic conferences in...

Climate clubs, namely subgroups of countries implementing more ambitious and effective climate policies than others, may be the only practical approach to address the lack of incentives to reduce GHG emissions on the part of most, if not all, countries. In climate clubs, incentives to undertake...

The paper proposes an agreement structure that extends Nordhaus's (2015) climate club by adding a second tier. Countries outside the coalition are required to price carbon at a fixed fraction of the average carbon price adopted within the coalition, or face tariffs. Coalition countries abate...

As reporting GHG emissions becomes mandatory in the financial sector, the methods by which emissions are calculated will grow in importance for their impact on the resulting metric. Progress is underway in both the public and private financial sectors to embed emissions accounting standards, but...

The stabilisation of GHG atmospheric concentrations at levels expected to prevent dangerous climate change has become an important, global, long-term objective. It is therefore crucial to identify a cost-effective way to achieve this objective. In this paper we use WITCH, a hybrid...

A two-tier climate club exploits the comparative advantage of large countries to mete out punishments through trade, while taking their capacity to resist punishment as a constraint. Countries outside the coalition price carbon at a fixed fraction of the average carbon price adopted within the...
