In California, an effort to reduce carbon emissions from vehicles came into conflict with the function of certain electronic devices — and the state’s Air Resources Board (ARB) has come down in favor of the electronics. ARB announced Thursday that the so-called Cool Cars rulemaking will now “cease.”

The decision to halt the rule, which would have required reflective metallic glazing on car windshields by 2012 and all windows in 2016 for vehicles sold in California, comes as a response to protests from stakeholders that the glazing would block or at least degrade in-car wireless reception for electronic devices.

Gadget makers, car companies and other groups have raised concerns that GPS navigation systems, mobile phones, toll-collection systems, ankle bracelets for monitoring parolees, and other devices would be affected by the glazing. This week’s decision points to the considerable influence of the auto and telecom lobbies, which campaigned against the mandate. In years past, as Edmunds has explained, ARB slashed requirements for fuel cell and all-electric vehicles (“zero emission vehicles”) to “accommodate automaker concerns that neither the technologies nor the marketplace are quite ready yet.”

This latest move marks a shift from the position suggested in an ARB report late last year. In November the agency released findings that the new rule, meant to help keep vehicles cool in the sun (and thus cut use of energy-guzzling air conditioners) could interfere slightly with signal reception for GPS devices, but probably wouldn’t block most mobile phone signals.

The Cool Cars initiative came as part of California’s Global Warming Solutions Act (AB 32), which mandates a drop in greenhouse gas emissions for the state to 1990 levels by 2020. According to ARB’s estimates, the regulation could prevent more than 1 million metric tons of carbon dioxide emissions from vehicles.

ARB deletion window testARB explained in the November report that it researched ways to work around the reception problem and decided to allow a small “deletion” window in the glaze (pictured at left), where signals would be able to come through unhindered. Garmin International, Toyota, Nissan and other companies were not convinced this allowance went far enough for their products.

According to a statement in Thursday’s release from ARB executive officer James Goldstene, the Board now plans to, “pursue a performance-based approach as part of its vehicle climate change program to reduce CO2 from air conditioning and provide cooler car interiors for California motorists.”

That performance-based option was already on the table for the 2016 step-up in the original ruling. ARB explained back in July 2009 (PDF) that automakers would have the option to meet the state’s target — blocking 60 percent of solar heat gain — with “a combination”of the required glazing and other solar control technologies.

Some of the options that ARB suggested at the time, and that we might see rolling out in coming years as a result of the new performance-based approach, include solar reflective paints, passive or active ventilation systems, solar reflective or thermo-regulating materials and vehicle insulation.

  3. I wish CARB would simply disband. At least with respect to automotive matters. They do not contribute ANYTHING, and at this point, they are more part of the problem than any solution.

    They were a key player in the “Lost Decade” of EV technology, as GM had developed the EV1, only to have the technology stall for 10 years when CARB decided to play kingmaker for hydrogen fuel cells.

      Room for improvement, sure, but I don’t see how totally disbanding CARB would accelerate adoption of lower-emission vehicles.

      1. I don’t see how having a lawyer (with no technical background) running CARB is an effective course of action. Mary Nichols does not even understand the hydrogen vs. battery argument, and simply pleads for both sides to try to “get along”. She doesn’t seem to understand that technology lapses cannot simply be fixed with legislation.

        I respectfully disagree. If CARB can’t lead (they don’t) or follow (they won’t), then they need to get out of the way (they won’t do that either).

        They now enjoy an annual budget of $750 Million, for which we’ve got the stalling of EVs for 10+ years. What a bargain!

  5. What sort of tax payer funded waste of time has this exercise been? To make the law in the first place without doing the required technical research is ridiculous, but to just kill it in response to special interest groups… people should be losing jobs over this.

    BTW Renault have been selling cars with metallic “UV reflective windscreens” for years and while these do block GPS signals, it’s hardly a big deal to use a cheap external antenna.
