Laurie Johnson, NRDC Chief Economist, takes on the Koch-fueled Heritage Foundation in a Switchboard repost.

Last week the Heritage Foundation released a critique of a report by EPA assessing the benefits and costs of the 1990 Clean Air Act amendments (click here for my summary). They should have done a little homework first, perhaps an intro class to research methods.  Had they, they might not have set themselves up so badly. Double checking their numbers would have been a good idea too.

A few critical errors made by Heritage undermine its critique:

  1. Heritage concluded that EPA’s analysis was not credible, for the simple reason that EPA had conducted it. But they neglected a critical protocol followed in good science: EPA’s work was exhaustively peer-reviewed. Its report was evaluated by preeminent academics and institutions (see details below); Heritage’s critique lacked any external examination whatsoever.
  2. EPA’s analysis was based upon an extensive body of peer-reviewed science (see details below); Heritage’s was based on none. Indeed, it only had one reference: a non peer-reviewed study conducted by an industry-funded conservative think tank (see details below).
  3. Heritage writes: “[I]t is simply preposterous to assume that air quality would worsen unabated over the course of 30 years in the absence of a particular statute”¦  History has proven otherwise”¦  Long before the original CAA was enacted in 1963, industrial emissions were declining as a result of technological advances and efficiency improvements.” What a preposterous argument. Common sense notwithstanding, data show the opposite: pollutants regulated under the CAA were increasing prior to the major CAA statutes, followed by a decisive decline after 1970. (Figure reproduced below).
  4. Heritage proclaimed the study invalid because it estimated a large range of possible benefits, $250 million at the 5th percentile (loosely speaking, a 5% likelihood) compared to a best estimate of $2 trillion. Two mistakes. First, this reveals an embarrassing understanding of basic statistical analysis. If I tossed a coin 20 times, my best guess on the number of heads would be 10. But it’s also possible only 1 head would come up. Does that make the best guess of 10 invalid? Second, they got the figure wrong: it was $250 billion. Had they gotten it right (or read the abstract, for that matter), they might have realized that even this low end estimate gave a 4/1 benefit cost ratio (see table on page 2 of the abstract, and the first paragraph on page 7-10),

Specifics:

Heritage external peer review: none.

Heritage supporting references:

One non peer-reviewed study by the Mackinac Center for Public Policy, a free market think tank that, according to IRS data, is funded almost exclusively by corporate and conservative foundations (e.g. oil giants ExxonMobil and the Koch brothers). When asked by Detroit’s Metro Times in 1996 on funding sources, the Center’s President Lawrence Reed said: “Our funding sources are primarily foundations “¦ with the rest coming from corporations and individuals,” but that “”¦ revealing our contributors would be a tremendous diversion”¦”

What was external review council’s final assessment of the report? Here’s an excerpt from its 12 page review:

The Advisory Council on Clean Air Compliance Analysis (Council) has offered technical advice and review to the Agency, including over a dozen advisory reports, during the 10-year period of the EPA effort to evaluate the benefits and costs of the Clean Air Act out to the year 2020″¦”

“The Council is impressed with the quality, scope, and presentation of the Second Prospective Report. The report provides a state-of-the-art analysis of the benefits and costs of the 1990 CAAA. It is comprehensive in scope, sophisticated in methodology, and is accessible to both specialist and non-specialist readers. The report includes methodological innovations that enhance our understanding of the benefits and costs of air-quality regulations”¦The Council commends the EPA Project Team for its work.

EPA supporting evidence:

66 references, including numerous peer-reviewed articles in top journals, research papers from top scholars at preeminent universities, studies from prestigious non-partisan research institutes (e.g. National Academies, Brookings, Research Triangle Park), and analyses by EPA’s external Scientific Advisory Board. These studies themselves drew upon hundreds of peer reviewed analyses.

Pollution levels increasing before 1970s statutes, decreasing thereafter:

The data does not support Heritage’s claim that pollutants regulated under the Clean Air Act were declining on their own before the major 1970 statutes were enacted. The graph shows clearly that pollution levels only began decreasing after being regulated, and were increasing prior to that:

Conclusion:

Enough said.

    Speaking about dirty air …

    Can a moderately sized photo voltaic solar panel generate enough energy to run one of the new electric cars like the Ford Focus or Nissan Leaf carbon free?

    What kinds of ranges are possible? What happens in the Winter time with low generation in the northern hemisphere?

    Here’s a new paper that applies 4 years of daily generation statistics to try and answer the question.

    Well, the Heritage Foundation could have cited Rush Limbaugh, Sean Hannity, Neil Bortz, and Glenn Beck. They’ll all certainly be citing the Foundation. Like a lightning storm in a box canyon, the echoes will continue for weeks. Wingnuts will cheer every repetition like a new great awakening because they’re not very bright and have no critical thinking abilities.

  3. BBHY says:

    The Heritage Foundation report has one overwhelming advantage: it states exactly what its intended audience wants to hear. To those people who have no interest in the truth, this report is perfect.

  4. BBHY says:

    Gord,

    I’m a little confused about that report. It states: “The Ravina Project lives and dies by numbers.”, but then makes this sweeping statement, unsupported by any numbers: “An e-car using 100% Grid power generated by coal is not clean and is not abating anything.”

    The numbers I have seen do not support that conclusion. Coal is certainly a dirty fuel source, but the efficiency gains of electrically powered transport can even make that an improvement over oil based fuels. It is a very complex situation, with lots of variables, so I can understand if that goes beyond the scope of the project, but then maybe that statement should be reworded to indicate that.

  5. Jeffrey Davis says:

    We’ve seen what “no pollution controls” looks like: it looks like China.

  6. Mike Roddy says:

    The press needs to stop greeting right wing “think tank” proclamations with a straight face. They should forget the retail screeds and go straight to the oil and coal companies and ask them what they want us to believe. That way they’ll get the “balance” they so desperately seek, and the public will be able to identify the source. You’d be surprised how many people are fooled by think tank papers, especially since they have such serious sounding names- Heritage, Cato, Heartland, CEI, and so on.

  7. Mark Shapiro says:

    Heritage Foundation might be thinking of Pittsburgh, which started cleaning up in the 1950′s, but even that was due to local regulations. From Wikipedia:

    “In 1946 [Mayor] Lawrence decided to enforce the Smoke Control Ordinance of 1941 because he believed smoke abatement was crucial for the city’s future economic development.”

  8. Gord says:

    The point we are trying to make is that if your car is charged with fuel that is the product of coal generation you load into your car the carbon that is released in its production. Merely to have a vehicle that is electric is not enough in an abatement program. The vehicle must be charged using a low or no carbon source to have a net positive effect in such a program.

    And yes, you are correct, we did not provide numbers for that assertion.

    Thank-you very much for your comments.

    I can hardly wait for this Heritage Foundation disinformation to begin circulating in the Rightwing media here. The Murdoch Archipelago will no doubt give it a run, with several inmates of their menagerie of Rightwing disinformationists singing its praises. The ‘journalists’ will push it too, as ‘news balance’, giving equal billing to science and anti-science, rationality and market fundamentalist ‘magic thinking’ as their terms of employment require. I’m sure Lomborg could use it. These are the type of creatures that go out of their vicious way to smear the likes of Rachel Carson, as a ‘mass killer’ equal to -you name your villain-for no other reason than that she started the current ecological waves with her great book, so no moral depth is too low for them to plumb. They are determined, though, you have to give them that.
