Nearly all discussions about the appropriate consumption discount rate for climate change policy evaluation assume that a single discount rate concept applies. We argue that two distinct concepts and associated rates apply. We distinguish between a social-welfare-equivalent discount rate...

There is a large number of regional agreements concerning Greenhouse Gas (GHG) emissions, often linked to other regional integration agreements. The most successful one in making effort in reducing carbon emissions is the Emission Trading System by the European Union (EU ETS). Apart from this...

Linkage of cap-and-trade systems is typically advocated by economists on a general analogy with the beneficial linking of free-trade areas and on the specific grounds that linkage will ensure cost effectiveness among the linked jurisdictions. An appropriate and widely accepted specification for...

Many poor countries are ill-adapted to the current leave alone a changing future climate, because they lack the necessary financial means to invest in efficient and costeffective safeguarding measures. International endeavours to fund institutions, such as the Green Climate Fund, to provide...

Current and proposed greenhouse gas cap-and-trade systems allow regulated entities to offset abatement requirements by paying unregulated entities to abate. These offsets from unregulated entities are believed to contain system costs and stabilize allowance prices. However, the supply of offsets...

Climate change policy analysis has focused almost exclusively on national policy and even on harmonizing climate policies across countries, implicitly assuming that harmonization of climate policies at the subnational level would be mandated or guaranteed. We argue that the design and...

Carbon markets are substantial and they are expanding. There are many lessons from experiences over the past eight years -- fewer free allowances, better management of market-sensitive information, and a recognition that trading systems require adjustments that have consequences for market...

Much of the guidance about potential impacts of reduce emissions from deforestation and degradation (REDD) speculates how efforts would be implemented and draws lessons from other mechanisms, such as payments for ecosystem services (PES). However, with few REDD activities underway, little...

On efficiency grounds, the economics community has to date tended to emphasize price-based policies to address climate change -- such as taxes or a “safety-valve” price ceiling for cap-and-trade -— while environmental advocates have sought a more clear quantitative limit on emissions. This...

In 2005, the European Union introduced the largest and most ambitious emissions trading program in the world to meet its Kyoto commitments for the containment of global climate change. The EU Emissions Trading Scheme (EU ETS) has some distinctive features that differentiate it from the more...
