A CAFE standard of 62 miles per gallon by 2025 might indeed come to pass. The Department of Transportation and the Environmental Protection Agency today released a "Notice of Intent to Improve Fuel Economy and Reduce Greenhouse Gas Emissions for 2017-2025" (PDF) that includes, as one possibility, decreasing greenhouse gas emissions by six percent a year for the years in question. A drop that steep would put us on track for 62 mpg, but the agencies are also looking at three, four and five percent

Fuel efficiency has been a hot topic as of late, both for consumers looking to ease their financial and environmental burdens and for automakers hoping to meet the latest round of government-mandated mileage requirements. A few months ago in late March – importantly, that means the survey was conducted before the major disaster and oil spill in the Gulf – the Consumer Federation of America found that most U.S. citizens support a major shift towards increased fuel mileage standards.

We knew it was coming. Today, the National Highway Traffic Safety Administration and the Environmental Protection Agency jointly released new Federal CAFE fuel mileage and greenhouse gas emissions requirements that will cover the 2012 through 2016 model years. The estimated fleet-wide fuel economy standard has been set at 34.1 miles per gallon by 2016, though improvements in air conditioning systems will bring that number up to around 35 mpg. That equals a standard of roughly 250 grams of carbon
