Road tolls, market forces and climate change

A news item caught my attention today. Toronto Mayor David Miller has stated he would consider tolling city roads -- as London England did, with great success -- in order to reduce commuting, downtown congestion and smog.

The London mayor who introduced tolling in that city was actually a left-wing mayor (like Miller) and the concept, which is market-oriented, was anathema to his political followers, who decried it as a tax on the poor and said it wouldn't work. Well, it did work. I have been to London twice in recent years and, while there is traffic, there is very little congestion, even during rush hour. The tolls place a "price" on driving downtown from outside the city. If people want to do it, they can, but they pay. Because it's not considered "free" people who have other options (public transit, not going downtown, taking taxis) use them, and the roads are less congested.

Tollling makes sense, if properly implemented, because it solves the "tragedy of the commons" where cars are concerned. When taxes pay for the construction of roads, people perceive their use of those roads as a right, and that their actions are without cost. But when too many cars clog the streets, there is in fact a cost -- loss to the economy from all those thousands of people sitting idle in traffic, wear and tear to the roadways themselves, and (most important) the cost in health care and environmental degradation from smog. It's excellent public policy to recognize this "cost" and to put a "price" on it. The price (market) signal turns the roadways into a market, rather than a commons.

Over time, people adjust their behavior according to the market signals. When the roadways are perceived as free, people behave perfectly rationally -- competing to squeeze out as much of their share of the free public good as they can (by using the roads during peak hours, commuting, etc.). It's utterly predictable that "free" roads encourage suburban sprawl. If you can buy a house in exurbia for, say, two-thirds the price of that same house downtown, and your only penalty is to have to drive a bit more every day and not have access to public transit for your work commute, you will logically move to the cheaper suburban house because you can pay off your mortgage much faster and, besides, enjoy a more "bucolic" existence away from the "trafficy" downtown. (Okay, many people will not make this choice, but a glance at any map of the GTA and it's enormous low-density suburbs shows that millions of people will.

But if you turn the commons into a market, if the roads are suddenly not "free" (at least, the downtown roads) then the equation changes. People don't so readily assume that it makes sense to live far apart from where they work. ?The cost of the impact of their behavior is no longer externalized onto taxpayers (in the form of road repairs, road construction, hospital care, etc.) or the general economy (the drag of millions of person-hours wasted in traffic). The cost is internalized directly back to the consumer of the service (the driver on the road).

There's a further benefit. Not only are costs being appropriately assigned to users of the system, but the system itself changes -- it self-corrects. The very traffic congestion that inspired the tolls begins to melt away as people re-order their affairs. In the short-term, they drive less often to the city. They start to car-pool (i.e., share costs). More than any amount of proslytizing from government (nanny state nagging) could accomplish about the value of car pooling, people do it because it saves them money. Aha! The same force that inspires them to turn down their thermostat or turn off lights in empty rooms, or comparison shop for cheaper shoes, gets them to do the "right thing for the environment." They discover the "Kiss-N-Ride" and jump on the commuter train. They take cabs, trains, buses, street cars, bicycles and (gosh!) they even walk!

Over the long term, the appeal of living in the suburbs and working downtown diminishes. Or, more correctly, people make decisions to follow such a pattern with the correct pricing in their heads. One can imagine that real estate values in urban cores -- even the cores of suburban areas -- will more perfectly reflect the value that one can work/shop/play in close proximity, and the values of outlying properties will be diminished. Butthis doesn't mean that the suburbds will become wastelands, ghettos. The opposite should occur: As municipal politicians see the new pattern, they will introduce planning rules to encourage density, thereby turning each suburban node into a small dense city unto itself, rather than a mere add-on to The Big Smoke. This is precisely what is happening now in the Town of Markham (where i once lived), which is a sad example of low-density sprawl that is reinventing itself and literally dropping a high-density core into its new "city centre." Light rapid transit and other public infrastructure will reinforce the idea over time that you can live in Markham, work there, and play, and only go downtown once in a while of other big city pleasures.

If this same mechanism is applied to other "free" services, a virtuous cycle should ensue. Markham, for instance, is introducing a user-pay system for garbage (bag tags), in combination with free (tag-less) collection of recyclable materials and organic waste. Unsurprisingly, the town is closing in on its goal of diverting 60 per cent of solid waste from landfill. The town already meters water consumption, which appears as a (not buried) line item on bills. Gas and electricity consumption is already metered by suppliers (including discounters with long-term contractual plans that lock in prices). Imagine the further advances that will be achieved in Markham and every other town and city when each appliance in each household is equipped with "smart meters" telling the owner/user exactly how much it's costing them -- in real time -- to use power for a given period. Again, pricing behavior appropriately will lead people to behave rationally, if they're provided a rational context.

If I know, for instance, that it will cost me half as much in electricty pricing to run my dishwasher during the night, while I'm asleep, I will take the time to figure out the slightly complicated digital setting on the front of the machine to make this happen. I will even dig out the owner's manual, or search for it online (by keying in the product name or description). Whereas such a task once sat idle on the endless "to do" task list (along with trimming the hedge in the front yard, or replacing the burnt-out back porch light), it now moves onto my priority "action list" for today, because of pricing. Smart metering will cause me to operate my clothes washer and dryer during non-peak hours for the same reason.

But again, there are other benefits and changes that will occur, that movefrom the individual to the systemic. For example, I will likely take a keen interest in the energy efficiency of every appliance that I own or purchase. I'll start to pay attention to the stickers on these machines, and the issue will become part of my research into what I will buy, beyond bottom-line price and styling. I might decide to retire the inefficient beer fridge in the basement when I learn that it's the single greatest power consumer in my home, sucking up power senselessly day and night. And that's just the "low-hanging fruit." I will eventually replace my standard incandescent light bulbs with fluorescents. I will buy rechargeable batteries instead of throwaways. I will install water-saving shower heads. And I may in fact do away with certain appliances altogether, or use them less. (I have recently discovered that it takes only slighly more time to wash dishes than load and empty the dishwasher. And since it makes for a good "chore" for my kids, it costs me nothing personally.)

Now let's switch to the view from ten thousand feet. If I'm doing this, millions of other people will be as well. Our combined rational behavior in the new system takes many many megawatts of consumption off the grid. But more importantly, market forces smooth out the peaks and valleys of power consumption. And, since electricty production and consumption is virtually instantaneous, new power plants are not required. The existing system can meet demand and even be in surplus, because infrastructure adequately serves the robust "middle" of consumption, rather than strain to meet peak demand (e.g., everyone cranking up their air conditioners on a hot summer's day, and running their dishwashers at the same time, etc., etc.).

And then the planners and the suppliers of power are under less pressure to build mega-projects based on worst-case demand scenarios, and can invest in a more diverse -- dare I say "green" -- array of options. Many people in Ontario, for example, are already buying their power from Bull Frog -- an alternative energy supplier that emphasizes hydroelectricty and wind, etc.

So I've extrapolated quite an arc of opportunities from the initial example of road tolls. Beyond municipal services like roads, drinking water and wastewater treatment, power supply, garbage collection and so on, many further opportunities exist in the realm of such things as extended producer responsibility for packaging, electronics and other products. I haven't even touched on trading/credit systems for emissions, that bring market discipline to another perceived "free" commons -- the atmosphere. But an interesting tie-in, in that regard, is that Toronto Mayor Miller's motivation to introduce road tolls is not directly about relieving traffic congestion, but rather to help get the city into compliance with its own four-year goal of reducing greenhouse gas emissions, and climate change impact.

The the very macro climate change issue is triggering very micro level policy instruments. A perfect example of "think globally, act locally." I believe that over time, more and more environmental activists will embrace market solutions to environmental problems, as command and control regulation proves to be an approach with certain limitations -- namely that it punishes bad behavior rather than reward correct (or, I should say, rational) behavior.

MILLER WOULD BACK ROAD TOLLS
Environmentalists urge
city to find ways to cut air pollution
BY JAMES COWANNational Post jcowan@nationalpost.com
Mayor David Miller said yesterday he would support ‘‘region-wide’’ road tolls, as environmentalists called upon City Hall to spend $1.3-billion annually to prevent climate change.


Mr. Miller said the city must consider all options to meet plans to reduce air pollutants by 20% within four years, but said he would support road tolls only if they were also imposed in neighbouring municipalities as well.


“It has to be a region-wide initiative,” said Mr. Miller, who has previously been reluctant to discuss congestion charges.


“If you toll the Don Valley Parkway, then Victoria Park [Avenue] and Don Mills Road will be jam-packed all day long. Plus, we don’t own all the roads in Toronto. We own the Don Valley but not Highway 427.”


Councillor Brian Ashton, the head of the city’s planning and transportation committee, is going to London, England, next week to study that city’s experience with $20 road tolls.


Councillor Raymond Cho suggested varying parking fees based on the number of occupants in a vehicle. He argued that if cars with multiple passengers were charged less, it would be an incentive for drivers to carpool.


“This is the life or slow death of the planet,” Mr. Cho said. “We really have to do something — or a lot of things.”


David McKeown, Toronto’s Medical Officer of Health, said congestion charges must be considered amongst other options.


“We have a very serious problem, and there’s no one solution that’s going to solve it,” he told reporters.


Mr. Miller said he is far more willing to consider charging parking levies in some areas of the city.


“Yes, the city will look at things like charging a levy in built-up commercial areas where there is excellent public transit,” he said. “Because that’s a choice people make. People who go to downtown Toronto have a choice. They can choose GO Transit or the subway.”


City staff are scheduled to unveil the first phase of the climate-change plan in June or July.


Yesterday, environmentalists called upon Toronto to invest in everything from road tolls to windmills. The parks and environment committee heard testimony from a panel of experts, the first step in the creation of a climatechange plan for the city.


Keith Stewart, WWF-Canada’s climate change campaign manager, told councillors it will take billions of dollars to effectively slash greenhouse gas emissions within Toronto’s borders. “We need to prioritize measures that get the biggest reductions — even if they are not the easiest,” Mr. Stewart said.


Proposals put forward yesterday included expanding the city’s network of bike lanes, offering financial incentives to make buildings more energy-efficient and installing windmills in Lake Ontario or on the Keele Valley landfill site. Numerous experts also advocated imposing new surcharges on drivers, ranging from road tolls to congestion charges to levies on downtown parking spots.

The new IPCC report on climate change

I thought readers would appreciate reading the article below from Associated Press that I read on the Internet, about the IPCC's latest report on climate change. I'll make some blog entries presently on this topic, along with posting an interesting "contrarian" article from Lawrence Solomon from the National Post a few days ago, wherein he describes the views of one of Russia's top climate scientists who says that Earth's warming is from increased radiance from the sun, and says this is undoubtedly so because Mars, which has virtually no climate, has warmed about the same amount as the Earth in the same time.

Global warming man-made, will continue

By SETH BORENSTEIN, AP Science Writer

Scientists from 113 countries issued a landmark report Friday saying they have little doubt global warming is caused by man, and predicting that hotter temperatures and rises in sea level will "continue for centuries" no matter how much humans control their pollution.

A top U.S. government scientist, Susan Solomon, said "there can be no question that the increase in greenhouse gases are dominated by human activities."

Environmental campaigners urged the United States and other industrial nations to significantly cut their emissions of greenhouse gases in response to the long-awaited report by Intergovernmental Panel on Climate Change.

"It is critical that we look at this report ... as a moment where the focus of attention will shift from whether climate change is linked to human activity, whether the science is sufficient, to what on earth are we going to do about it," said Achim Steiner, the executive director of the U.N. Environment Program.

"The public should not sit back and say 'There's nothing we can do'," Steiner said. "Anyone who would continue to risk inaction on the basis of the evidence presented here will one day in the history books be considered irresponsible."

The 21-page report represents the most authoritative science on global warming as the panel comprises hundreds of scientists and representatives. It only addresses how and why the planet is warming, not what to do about it. Another report by the panel later this year will address the most effective measures for slowing global warming.

One of the authors, Kevin Trenberth, said scientists are worried that world leaders will take the message in the wrong way and throw up their hands. Instead, world leaders should to reduce emissions and adapt to a warmer world with wilder weather, he said.

"This is just not something you can stop. We're just going to have to live with it," said Trenberth, the director of climate analysis for the National Center for Atmospheric Research in Boulder, Colo. "We're creating a different planet. If you were to come up back in 100 years time, we'll have a different climate."

The scientists said global warming was "very likely" caused by human activity, a phrase that translates to a more than 90 percent certainty that it is caused by man's burning of fossil fuels. That was the strongest conclusion to date, making it nearly impossible to say natural forces are to blame.

It also said no matter how much civilization slows or reduces its greenhouse gas emissions, global warming and sea level rise will continue on for centuries.

"Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level," the scientists said.

The report blamed man-made emissions of greenhouse gases for fewer cold days, hotter nights, killer heat waves, floods and heavy rains, devastating droughts, and an increase in hurricane and tropical storm strength — particularly in the Atlantic Ocean.

Sharon Hays, associate director of the Office of Science and Technology Policy at the White House, welcomed the strong language of the report.

"It's a significant report. It will be valuable to policy makers," she told The Associated Press in an interview in Paris.

Hays stopped short of saying whether or how the report could bring about change in President Bush's policy about greenhouse gas emissions.

The panel predicted temperature rises of 2-11.5 degrees Fahrenheit by the year 2100. That was a wider range than in the 2001 report.

However, the panel also said its best estimate was for temperature rises of 3.2-7.1 degrees Fahrenheit. In 2001, all the panel gave was a range of 2.5-10.4 degrees Fahrenheit.

On sea levels, the report projects rises of 7-23 inches by the end of the century. An additional 3.9-7.8 inches are possible if recent, surprising melting of polar ice sheets continues.

The panel, created by the United Nations in 1988, releases its assessments every five or six years — although scientists have been observing aspects of climate change since as far back as the 1960s. The reports are released in phases — this is the first of four this year.

"The point here is to highlight what will happen if we don't do something and what will happen if we do something," said another author, Jonathan Overpeck at the University of Arizona. "I can tell if you will decide not to do something the impacts will be much larger than if we do something."

As the report was being released, environmental activists repelled off a Paris bridge and draped a banner over a statue used often as a popular gauge of whether the Seine River is running high.

"Alarm bells are ringing. The world must wake up to the threat posed by climate change," said Catherine Pearce of Friends of the Earth.

Stephanie Tunmore of Greenpeace said "if the last IPCC report was a wake up call, this one is a screaming siren."

"The good news is our understanding of the climate system and our impact on it has improved immensely. The bad news is that the more we know, the more precarious the future looks," Tunmore said in a statement. "There's a clear message to governments here, and the window for action is narrowing fast."
