  1. Buy Coal ! A Case for Supply-Side Environmental Policies Awarded the Erik Kempe Prize 2013 Published in Journal of Political Economy Bård Harstad

  2. Three Numbers* I. 2 grader Celsius . Temperate-increase threshold set by international negotiators (UN) II. 565 Gigaton . Amount CO 2 we can release before 2050 to meet the temperature target III. 2795 Gigaton . Amount known resources of carbon * Bill McKibben, the Rolling Stone Magazine 19. juli 2012:

  3. The Problem  Many countries are unwilling to cooperate  If only a subset of countries cooperate, the climate policy will be ineffective:  Nonparticipants will consume and extract too much  +Carbon leakage: If coalition consume less, fossil- fule price declines and others consume more  If coalition extracts less, others extract more  => Less motivation to participate  Strategic policy will distort international trade Bård Harstad

  5. The Market for Fuel

  6. The Policy Stage

  7. Reduction of consumption price* demand* consumption*  Price declines  Fossil fuel consumption abroad ↑ (particularly if demand-function “flat”) Bård Harstad

  8. Reduction of extraction price* supply* utvinning*  Price increases  Extraction abroad ↑ (particularly if foreign supply “price sensitive”) Bård Harstad

  9. The Policy Stage  Consume less? Price down and others consume more  Extract less? Price up and others extract more  Balance the two: If supply “elastic” (price sensitive) then better to consume less  Climate policy affects the terms-of-trade, so a fossil-fuel importing coalition will focus on less consumption (in order to reduce global price)

  10. Inefficiences  Free-riders consume too much & extract too much  Price is low => free-riders invest little in R&D  Wrong types of fuel extracted  Coalition’s policy distorts international trade  Policy is not “time consistent” (green paradox)  Not very attractive to cooperate

  11. The market for extraction right price* supply* p c extraction*  Profit is p - c  Gains from buying if Damage> p-c Bård Harstad

  12. A “secondary” effect price* supply* p c extraction*  Foreign supply becomes less sensitive to the price  This reduces carbon leakage on the supply side!  => optimal to reduce extraction, not consumption Bård Harstad

  13. A “secondary” effect price* supply* p c extraction*  Consumption-price will be equal abroad/home  This price is high, so all invest more in R&D  The “ socially optimal ” solution is implemented! Bård Harstad

  14. Literature  The Coase Theorem  If property rights are well-defined: Efficient  Here: Enough with bilateral trade in “inputs”  Peter Bohm (1993) provided an…  example of when buying foreign deposit beneficial  But unclear when beneficial more generally  No research since… Bård Harstad

  15. Realistic?  Seen it before: REDD  Market exists already  Cheap: Buy only barely profitable fields  Administration is easy  Fear re-nationalization? Lease! Bård Harstad

  20. SPIEGEL ONLINE: Minister Eide, do you see yourself as representing a reckless country? Eide: No, not at all. On the contrary. SPIEGEL ONLINE: An environmental committee of the British parliament recently called drilling for oil and natural gas in the Arctic a "reckless gold rush.“ Eide: The exploitation of Arctic resources will happen. The Economist: …those greens who have set their hopes on the eco- attuned Inuit or Scandinavians taking a stand against Arctic warming are likely to be disappointed. Bård Harstad
