Buy Coal?

Purchasing the dirty fossil fuel could help fight climate change

Based on the research of

Bård Harstad

Coal is the poster child of carbon-emitting fossil fuels, a distinction that is easy to understand for anyone who has seen a power plant belching black soot from its smokestacks. But Bård Harstad wants to clear the air about coal. He thinks the dirty-burning fuel could be key to combatting climate change.

Harstad, an asso­ciate pro­fes­sor of man­age­r­i­al eco­nom­ics and deci­sion sci­ences at the Kel­logg School of Man­age­ment, has been cast­ing an economist’s eye on the suc­cess­es and short­com­ings of multi­na­tion­al cli­mate change treaties. Some of his pre­vi­ous work has sug­gest­ed that short-term cli­mate treaties were harm­ing efforts to curb glob­al car­bon emis­sions more than no treaties at all. Adding to his cat­a­log on cli­mate change leg­is­la­tion, Harstad now has anoth­er coun­ter­in­tu­itive pro­pos­al. Buy coal, he says. Lots of it.

The fatal flaw in most multi­na­tion­al cli­mate agree­ments lies in the role of non­par­tic­i­pat­ing coun­tries, Harstad notes. In the short his­to­ry of major cli­mate change ini­tia­tives, coun­tries that agree to help reduce car­bon emis­sions begin by tack­ling demand. Emis­sion caps, car­bon tax­es, and alter­na­tive forms of ener­gy are all pur­sued in an effort to low­er the amount of car­bon enter­ing our atmos­phere by mak­ing it finan­cial­ly appe­tiz­ing to decrease the amount of fuel we con­sume. The trou­ble is, Harstad says, those efforts soon become coun­ter­pro­duc­tive, thanks to the coun­tries that do not sign on.

If the coali­tion reduces its demand for fos­sil fuel, the world price declines and non­par­tic­i­pat­ing coun­tries find it opti­mal to pur­chase more oil or fos­sil fuels,” he explains.

Fix­ing the Leak
The Inter­na­tion­al Pan­el on Cli­mate Change has dubbed this phe­nom­e­non car­bon leak­age,” and it proves unavoid­able in attempts to address cli­mate issues from what econ­o­mists like Harstad call the demand” side of the prob­lem. Not only do fos­sil fuels get cheap­er, result­ing in increased con­sump­tion by non­par­tic­i­pat­ing coun­tries, but the pro­hib­i­tive reg­u­la­tions enact­ed to curb demand in coali­tion coun­tries can push indus­tries to more accom­mo­dat­ing nations where car­bon emis­sions are not regulated.

Up to now, most of the lit­er­a­ture and polit­i­cal strate­gies have focused on demand. And a lot of prob­lems arise if you focus on the demand side,” Harstad says. What I show [in my research] is that those prob­lems dis­ap­pear when you focus on the sup­ply side, includ­ing the sup­ply of oth­er countries.”

In Harstad’s sup­ply-side mod­el for a glob­al cli­mate treaty, coali­tion coun­tries would essen­tial­ly cre­ate a mar­ket for coal and oil deposits. To do this, they would first buy up the mar­gin­al sources of fos­sil fuels, i.e., deposits that are very cost­ly to exploit. Once they owned the rights to these coal mines or nat­ur­al gas deposits or oil fields, they would sim­ply decline to devel­op them. They could also sell or lease the rights to pro­duce fuel from them under the con­di­tion that any coun­try buy­ing the rights would be sub­ject to the para­me­ters of the treaty.

Even­tu­al­ly, non­par­tic­i­pat­ing coun­tries would have devel­oped all of their fos­sil fuel deposits and coali­tion coun­tries would own the rest of the mar­gin­al deposits. By reduc­ing the sup­ply of fos­sil fuels avail­able on the mar­ket, the coali­tion coun­tries could then ensure that non­par­tic­i­pat­ing coun­tries would not have the fos­sil fuel resources to dras­ti­cal­ly increase their own car­bon emissions.

By employ­ing sup­ply-side poli­cies only with­out lim­it­ing demand, the coali­tion would cre­ate a mar­ket in which the fos­sil fuel con­sump­tion price” would be equal­ized across all coun­tries. At this point the mar­ket would clear, Harstad says, as no two coun­tries could make trans­ac­tions of fos­sil fuels that would lend unqual­i­fied ben­e­fit to both. In oth­er words, some­one would have to pay. And in the absence of cheap, read­i­ly avail­able sources of fuel, car­bon leak­age would no longer derail glob­al car­bon emis­sion reduc­tion efforts.

Under these con­di­tions, the first-best out­come is reached and, regard­less of full par­tic­i­pa­tion or not, Harstad writes, the coali­tion imple­ments its ide­al pol­i­cy sim­ply by reduc­ing its sup­ply of fuel. There is no need to reg­u­late trade or con­sump­tion and there is thus no con­sump­tion leak­age. The fos­sil fuel price is equal­ized across coun­tries, which induces opti­mal invest­ments in technology.” 

The key is that, by lim­it­ing sup­ply, coali­tion coun­tries could in effect set the price at a point that would encour­age ener­gy con­ser­va­tion and make invest­ments in alter­na­tive fuels more alluring.“Whether the right to exploit fos­sil fuel deposits is for sale or rent,” he says, the out­come is efficient.”

Mon­ey Can’t Be Every­thing
This may seem at first like wish­ful think­ing at first. It makes no finan­cial sense to pay for some­thing only to ensure that it is not used. But to address glob­al warm­ing, the world needs to be moti­vat­ed by more than finan­cial con­sid­er­a­tions. And Harstad’s sup­ply-side log­ic is not as improb­a­ble as it might seem. In fact, both the Unit­ed Nations and the World Bank are already address­ing one facet of cli­mate change through the sup­ply-side par­a­digm. In this case, the mar­ket is the world’s trop­i­cal timber.

But to address glob­al warm­ing, the world needs to be moti­vat­ed by more than finan­cial considerations. 

In the past few decades, con­sumers and gov­ern­ments in devel­oped coun­tries have become aware of the rapid defor­esta­tion of some of the world’s most boun­ti­ful and bio­di­verse ecosys­tems. As envi­ron­men­tal aware­ness rose, the price for trop­i­cal tim­ber dropped, thanks to reduced demand caused by both con­sumer reluc­tance and gov­ern­ment-imposed boy­cotts. How­ev­er, oth­er coun­tries that had been unable to afford tim­ber then increased their con­sump­tion. This tim­ber leak­age” became a huge threat to efforts to save trop­i­cal rainforests.

Defor­esta­tion is a major cause of cli­mate change, accord­ing to the Unit­ed Nations. It esti­mates that trop­i­cal defor­esta­tion and the result­ing land use changes account for near­ly 20 per­cent of the world’s car­bon emis­sions. Much like fos­sil fuel deposits, demand-side approach­es to the prob­lem were not work­ing, so the UN devel­oped a pro­gram called Reduc­ing Emis­sions from Defor­esta­tion and for­est Degra­da­tion, or REDD

The plan, says the UN, is to cre­ate a finan­cial val­ue for the car­bon stored in forests.” What that trans­lates into is pay­ing devel­op­ing coun­tries to pre­serve their rain­forests, to leave a mar­ketable resource untouched. Cur­rent­ly, Nor­way, Den­mark, and Spain are financ­ing forests in south­ern hemi­sphere coun­tries like Bolivia, Viet­nam, and the Demo­c­ra­t­ic Repub­lic of the Congo.

Harstad believes a sim­i­lar mar­ket for car­bon deposits could be suc­cess­ful. As he points out, he is not try­ing to invent a whole new way of doing busi­ness. In real­i­ty, a mar­ket for exploit­ing fos­sil fuel deposits already exists, since coun­tries fre­quent­ly sell, auc­tion, license or out­source the right to extract their own oil and oth­er min­er­als to inter­na­tion­al com­pa­nies, as well as to major coun­tries like India and China.”

Admit­ted­ly, there are com­pli­ca­tions. For exam­ple, non­par­tic­i­pat­ing coun­tries might be inclined to search for new deposits of fuels to get around the pro­hib­i­tive costs of exist­ing sup­plies or to sell them to the cli­mate coali­tion, which intends to con­serve them. (The lat­ter moti­va­tion for explo­ration is con­sid­ered an eco­nom­ic inef­fi­cien­cy — the coun­tries would be search­ing for deposits for the wrong rea­son.) And some schol­ars point to the green para­dox,” which pre­dicts a short-term rise in car­bon emis­sions as coun­tries scram­ble to use it now if it will get hard­er to do so in the future,” Harstad says.

Besides, per­haps par­tic­i­pa­tion is no longer such a big prob­lem. In Decem­ber 2010, 194 coun­tries signed the Can­cun Agree­ment that came out of the UN’s 16th Con­fer­ence of the Par­ties of the Unit­ed Nations Frame­work Con­ven­tion on Cli­mate Change. In 1997 only 37 coun­tries signed the Kyoto Pro­to­col. Sure­ly con­cerns about non­par­tic­i­pa­tion should be alleviated.

But Harstad is quick to point out, the Can­cun Agree­ment is non­bind­ing and will rely essen­tial­ly on good­will and vol­un­tary coop­er­a­tion. And that brings it all back to par­tic­i­pa­tion. Undoubt­ed­ly, many coun­tries will not chip in” at the lev­el of oth­ers. There will also be hag­gling over specifics of cap and trade sys­tems or car­bon tax­es or what­ev­er demand-side approach the coali­tion takes to reduce car­bon emissions.

The beau­ty of Harstad’s sup­ply-side mod­el is that pos­i­tive out­comes could still be achieved even if the world’s lead­ers are not all on the same page. Coun­tries may be unwill­ing to sign on to multi­na­tion­al cli­mate agree­ments or drag their feet at tak­ing the steps need­ed to reduce their car­bon emis­sions, but when it comes to join­ing a mar­ket for the fos­sil fuels cur­rent­ly need­ed to pow­er our world, they can­not sim­ply sit on the sidelines.
