Facts, Credible Research Undercut E15 Claims

One of the oft-repeated claims of ethanol producers is that higher-ethanol blend fuels like E15 are better for air quality than the E10 gasoline that’s the staple of the U.S. fuel supply. Short response: No. And while we’ve addressed the ethanol/air quality claim recently here and here, spurious assertions often have more lives than Lulu, my daughter’s cat. So let’s look at the facts and credible research again.

We’ll underscore “facts and credible research,” because an advocacy group is promoting a study on ethanol, air quality and potential cancer risks that isn’t an original study at all. Rather, it’s an overly simplistic exercise in data aggregation that ignores the confounding effects of different test procedures, laboratories and fuel properties. In other words, it’s a crummy analysis that would send real scientists running in the other way.

Air Quality, Exports and Energy Infrastructure Needs

Reuters: Rising U.S. imports of crude oil from Canada's oil sands have not increased greenhouse gas emissions from the country's oil refineries because they have been offset by refining of cleaner domestic crudes, a report from a private sector think tank said on Monday.

The report, from industry consultants IHS CERA, comes as the Obama administration moves to cut greenhouse gas emissions from the U.S. power sector by 30 percent from 2005 levels by 2030, under new rules aimed at reducing America's longstanding reliance on burning coal to generate electricity.

The oil sands sector has faced frequent criticism from environmentalists concerned about greenhouse gas emissions. U.S. imports of carbon-rich Canadian oil-sands crudes grew by 900,000 barrels per day to more than 2 million bpd between 2005 and 2012, according to the IHS CERA report.

It said they did not result in higher greenhouse-gas intensity from the energy sector, however, as other crudes imported from abroad were supplanted by so-called tight oil from domestic shale-oil deposits.

The Environmental Protection Agency (EPA) is moving forward with proposals that could sound the death knell for millions of jobs across the country. We've already told you about the potentially disastrous effects of the EPA's proposed ozone standard and its plan to regulate greenhouse gas (GHG) emissions, but there's more--much more.
