Putting a price on carbon is critical for climate change policy. Increasingly, policymakers combine multiple policy tools to achieve this, for example by complementing cap-and-trade schemes with a carbon tax, or with a feed-in tariff. Often, the motivation for doing so is to limit undesirable...

This paper analyses the design of carbon markets in space (i.e., geographically). It is part of a twin set of papers that, starting from first principles, ask what an optimal global carbon market would look like by around 2030. Our focus is on firm-level cap-and-trade systems, although much of...

This paper analyses the design of carbon markets in time (i.e., intertemporally). It is part of a twin set of papers that ask, starting from first principles, what an optimal global carbon market would look like by around 2030. Our focus is on firm-level cap-and-trade systems, although much of...

This paper analyses the design of carbon markets in time (intertemporally) and space (geographically) from first principles, starting initially with a relatively clean slate and asking what an optimal global carbon market would look like by around 2030. Our focus is on firmlevel trading systems,...

Schelling (1995) stressed the importance of correctly disaggregating the impacts of climate change to understand how individual interests differ across space and time. This paper considers equity implications at a level of disaggregation which we consider insightful, but which is non-standard in...

Conventional cost-benefit analysis incorporates the normally reasonable assumption that the policy or project under examination is marginal in the sense that it will not significantly change relative prices. In particular, it is assumed that the policy or project does not change the underlying...

There is an increasing demand for putting a shadow price on the environment to guide public policy and incentivize private behaviour. In practice, setting that price can be extremely difficult as uncertainties abound. There is often uncertainty not just about individual parameters but about the...

Poor countries are more heavily affected by extreme weather events and future climate change than rich countries. One of the reasons for this is the so-called adaptation deficit, that is, limits in the ability of poorer countries to adapt. This paper analyses the link between income and...

Policy interest in the cost of adaptation is growing, but compared to the mitigation literature adaptation cost research is still in its infancy. Global adaptation cost estimates from more recent studies range from around $25 billion a year to well over $100 billion by 2015-2030. The wide range...
