Despite ambitious climate goals and already substantial stocks of developed fossil energy reserves, development of new fossil energy reserves continues to be high. This raises concerns, as it reinforces the fossil industry’s opportunities and incentives to continue extraction, and may...

This paper explains how, in the context of incomplete coordination among all countries, unilateral policies that might at first sight seem pro-green could actually turn out to harm the global environment. The free-riding motives and the difficulty of reaching an effective international...

We investigate how irreversibility in "dirty" and "clean" capital stocks affects optimal climate policy, from both theoretical and numerical perspectives. An increasing carbon tax will reduce investments in assets that pollute, and so reduce emissions in the short term: our "irreversibility...

Several recent articles have analyzed climate policy giving explicit attention to the non-renewable character of carbon resources. In most of this literature the economy is treated as a single unit, which in the context of climate policy seems reasonable to interpret as the whole world. However,...

What will come first - non-acceptable global warming or extinction of oil reserves? Both processes can bring substantial costs to the mankind, but their order has important economic implications. The answer to this question will either lower oil price in the long run or will lead to its further...

Established by the United Nations in 2015 with a target date of 2030, the Sustainable Development Goals (SDGs) provide a framework with specific objectives to guide global development policy. The SDGs extend and modify an earlier framework, the Millennium Development Goals (MDGs), established in...

There is growing interest in international coordination over climate mitigation policy. Climate clubs or international carbon price floors could complement the Paris Agreement by helping to deliver the near-term cuts in global greenhouse gas emissions needed to contain global warming to 1.5 to...

Different reports including the broadly cited OECD fossil fuel subsidy inventory arrive at high monetary values of fossil fuel subsidies and suggest that phasing out these subsidies has a high potential to increase the efficiency of climate policies. We show that the inventory approach gives...

We show that OPEC's market power contributes to climate change by enabling producers of relatively expensive and dirty oil to start producing before OPEC reserves are depleted. We examine the importance of this extraction sequence effect by calibrating and simulating a cartel-fringe model of the...
