Do
low permit prices signal market failure?
The New
York Times worries that that the market for buying and selling
air-pollution permits in Europe generates too
many greenhouse gases.
“ …The penny ante price of carbon credits
means the market is not doing its job: Pushing polluters to reduce carbon
emissions…,” write Timesmen Stanley
Reed and Mark Scott.
Actually, that’s the European Union’s
job. The market’s job is to provide the
amount of cleanup mandated by the EU as cheaply as possible, in terms of
resources used up. If we can abate
another ton of carbon emissions with the toil of one worker rather than two,
then let’s do it. The second worker can
do something else useful, like research.
The permit market is unusual. Most markets determine the quantity as well
as the price of the product offered. If
the demand for roses rises in February, then the resulting price increase will
induce florists to sell more roses. But
the market for pollution permits sets only
the price. The number of permits is
determined by EU authorities. If they
print too many permits (that is, demand too little cleanup), then that’s their
fault, not the market’s.
Why not use a conventional market for
permits? Because it won’t work. The producer of cleanup technology cannot
collect a payment from everyone who benefits from it, so he will supply too
little technology. One solution (maybe)
is to have the government require polluters to clean up by issuing them just a few
pollution permits. Polluters will demand
more cleanup equipment when it’s cheaper than permits. The producer of the equipment can easily
identify the major polluters, so he can collect enough money from them to make
production of the equipment worthwhile.
The
sweet smell of excess
The Times
writes: “When the emissions trading
system was started in 2005, the goal was to create a global model for raising
the costs of emitting greenhouse gases and for prodding industrial polluters to
switch from burning fossil fuels to using clean-energy alternatives like wind
and solar.
“When carbon prices hit their highs of more
than 30 euros in 2008 and companies spent billions to invest in renewables,
policy makers hailed the market as a success. But then prices began to fall.
And at current levels, they are far too low to change companies’ behaviors,
analysts say.”
The Timesmen
– excuse me: “analysts” -- have the story backwards. The new cleanup technologies have reduced
polluters’ demand for permits. It’s
often cheaper now to switch to a clean fuel, like natural gas, than to buy a
permit to burn carbon-loaded coal. Since
polluters no longer want permits, their price has fallen. That’s a sign of success.
This matter is vital for Central
Asia. As transition
economies continue to grow rapidly, they will emit more and more
pollution. We would like to reduce emissions
without destroying too many jobs. A
permit market induces cleanup by those polluters who can do so most
cheaply. If Central
Asia refuses to set up permit markets because it misunderstands
the European experience, then it will probably revert to the old
“command-and-control” policy in which each polluter cuts back emissions by the
same percentage, regardless of the expense.
That would waste resources – a luxury that poor countries cannot afford.
