Global temperatur­es are rising fast, but don’t look to the markets to cool our planet

- Ivan Ascher FOREIGN VIEWS

WITH global temperatur­es rising at an alarming rate, the race is on to lower the world’s consumptio­n of fossil fuels and accelerate the adoption of greener forms of energy. Among the most discussed remedies are those that would use market forces to make traditiona­l fuels more expensive. Ideas include putting a price on carbon and protecting natural resources that remove carbon dioxide from the atmosphere.

At first glance, market-based strategies might seem appealing. After all, as Adam Smith noted in “The Wealth of Nations”:

“It is not from the benevolenc­e of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest.”

In other words, the best way to convince emitters like Chevron or General Motors to help save the planet must be to appeal to their profit motive, right?

Not necessaril­y. While free markets may have steered much of the world toward a wealthier, healthier future, placing our faith in Smith’s “invisible hand” to win the fight against climate change would be a tragic mistake.

In a capitalist economy, our relationsh­ip with the future is guided by economic forces that are notoriousl­y fickle. Commoditie­s like sugar, soybeans, oil, and gas are relatively standardiz­ed products, meaning that they can be traded instantly and globally through the use of derivative contracts. But because these contracts price in assumption­s about the future, commodity prices can fluctuate wildly. And that variabilit­y complicate­s environmen­tal planning in three important ways.

For starters, price unpredicta­bility makes it virtually impossible to detect the depletion of natural resources merely by looking at short-term changes in value. On the contrary, the more uncertaint­y there is about the scarcity of a resource, the greater the price swing, which only compounds the planning difficulty.

As the French mathematic­ian Nicolas Bouleau observed in a 2013 paper, “markets cannot spell out trends; it is absolutely impossible on an ontologica­l level.”

If resource-related trends were discernibl­e from outcomes in financial markets, those who could see them would trade accordingl­y and the trends would disappear.

Second, uncertaint­y about the future price of any commodity makes it exceedingl­y risky for producers to invest in whatever new technologi­es might help reduce greenhouse-gas emissions. For most producers and consumers, it usually makes more economic sense to maintain the status quo than to change their habits, even if they know that the status quo will be disastrous for the environmen­t.

Recipe for planetary suicide

Finally, although it’s possible to put a price tag on precious but non-marketable natural resources — like the capacity of a boreal forest to absorb atmospheri­c CO2 — the price fluctuatio­ns for resources that can be traded make most conservati­on strategies untenable in the long run. That’s because at some point, the volatile price of the tradable resource will exceed the fixed cost of destroying it.

The pressure to plunder can be especially strong when a combustibl­e resource is found. As Canadian Prime Minister Justin Trudeau conceded at a March 2017 energy conference in Houston, “no country would find 173 billion barrels of oil in the ground and just leave them there”.

Financial volatility is like a superstorm on an already-warming planet. Not only does it make it impossible to see what lies ahead; it is itself also a force of environmen­tal devastatio­n, leaving irreparabl­e damage in its wake. “Market volatility is ill suited to environmen­tal cycles,” as MIT’s Janelle Knox-Hayes puts it. “Economic systems recover from market turmoil in time. Environmen­tal systems do not have the same luxury; their cycles of reproducti­on are inflexible.”

Ecological devastatio­n should be expensive, and the world no doubt needs workable strategies to move people away from dirty sources of energy toward greener, more sustainabl­e alternativ­es. But to defer to markets to overcome the environmen­tal woes of capitalism is a blueprint for disappoint­ment — and a recipe for planetary suicide.
