From The Mountain Town News (Allen Best):
In Colorado, as elsewhere, recent polling by Yale University shows strong recognition that climate change is real, the result of human activity, and something that we must address.
But do it now? Really shake things up? Well, maybe it can wait. It ranks very low on the list of priorities for most people. Kick that can down the road.
A report released [September 20, 2017] by Western Resource Advocates and Conservation Colorado called Colorado’s Climate Blueprint argues that Colorado must seize very tool available to do its part in holding temperature increases to no more than 1.5 to 2 degrees Celsius.
“We need to reduce our carbon pollution very quickly,” says Stacy Tellinghuisen, a co-author of the report. “We can’t wait for the federal government to take action. So we have laid out a blueprint for a three-legged stool of action.”
Colorado has been doing things. Emissions in the electrical sector has fallen, since 2007, the result of switching from coal-fired generation to cleaner-burning natural gas but also as a result of the deepening penetration of renewables. Transportation sector emissions have also declined.
But the growing evidence uncovered by scientists argues that, if anything, their assessment of the risk has been conservative. Temperatures are rising, and so are sea levels. Coral reef is disappearing. If the hurricanes and bark beetle epidemics are not directly a result of the warming climate, their severity may well be exacerbated.
And if they’ve tended toward conservative predictions, what does that say about when they believe the spit really hits the fan within a few decades?
All of this argues for rapid reduction, not just stabilizing, of emissions.
Gov. John Hickenlooper in July announced a goal of reducing greenhouse gas emissions 26 percent by 2025 as compared to 2005 base levels. He did not, however, identify exactly how to achieve this, as I wrote in an article for the Colorado Independent. See: “What will it take to reach the climate change goals set by Gov. Hickenlooper?”
These two groups, arguably Colorado’s most influential environmental organizations, want significant reductions beyond Hickenlooper’s 2025 goals. By 2030, as compared to 2005 levels, they want a goal of 45 percent reduction in emissions and a 90 percent reduction by mid-century.
Unlike Hickenlooper’s order, they go into depth. Some are the the usual suspects. For example, the Colorado Public Utilities Commission can push the shift already underway from coal, in particular, to renewable sources. Colorado legislators need to ensure new buildings better maximize energy efficiency.
But the report points to several levers that the Air Quality Control Commission can pull to achieve action. One is advanced regulations that reduce the venting and flaring of methane, as is commonly done in the Wattenberg and other natural gas fields.
Tellinghuisen says the gasfield emissions of methane are among the most difficult areas for regulation. In 2010, they represented almost 8 percent of Colorado’s total carbon pollution. Colorado subsequently became a national leader in its regulation of methane emissions after the state’s two largest operators, Anadarko and Noble, working with the Environmental Defense Fund, emerged with an agreement. But more methane, the primary constituent of natural gas, remains to be captured instead of being allowed to be wasted. If prices of natural gas were higher, producers would have more incentive to attend to leaks and capture what is now being flared. Methane has 22 to 28 times the heat-trapping properties of carbon dioxide.
The two groups would also like to see more stringent fuel economy standards for vehicles, similar to what California and 10 other states have adopted. Colorado, they say, should adopt policies that yield one million electric cars by 2030. It ranked 12th in the nation in sales of EVs from 2011 through 2016.
What may be most notable about the report is the embrace of market-based solutions. The power of markets has been proven frequently in solving environmental problems. Markets, by definition, must have incentives, in this case a price on carbon in this case. This could be achieved through a cap-and-trade regime or the more straight-forward carbon tax.
California has adopted a cap-and-trade system, and several states in the northeast have cap-and-trade as it applies to electrical production. British Columbia has a carbon tax. That province adopted a tax of 410 in 2008 and, as previously planned, elevated it to $30 in 2012. As the New York Times noted in a March 2016 story, that was then the equivalent of $22.20 in U.S. dollars. Economists at Duke University and the University of Ottawa in a 2015 study concluded that the carbon tax had reduced emission by 5 to 15 percent with “negligible effects on aggregate economic performance.”
The tax proceeds are rebated to the public in the form of other tax reductions. A group called Citizens’ Climate Lobby advocates the same revenue-neutral approach in advocating for what it calls a carbon fee and dividend.
From her study, Tellinghuisen believes a higher tax is needed to motivate changes in the transportation and other sectors. A tax of $20 per ton of CO2 emissions would result in a price increase of only 20 cents per gallon on gasoline. That, Tellinghuisen points out, would likely be lost in the noise of price fluctuations at the gas pump. It’s not enough to motivate changes such as, for example, cause people to ride light rail.
A constitutional provision in Colorado would also pose a challenge to automatic price increases in carbon prices if Colorado should follow the British Columbia model. The Taxpayers’ Bill of Rights, or TABOR, requires specific voter approval for many specific tax increases.
Many economists say the minimum starting price for a carbon tax would be $40, if it is to produce significant changes, elevating to about $75 a ton.
Voters in Washington state, belying their reputation for liberal instincts, rejected a proposed carbon tax there last November. Among the arguments was that the tax is regressive, hurting poor people more than other sectors of society.
