The monitoring program at the National Oceanic and Atmospheric Administration reports the level of carbon dioxide gas in the atmosphere has passed a troubling milestone, reaching an average daily level above 400 parts per million. (That’s bad, in case you were wondering.) It’s what one New York Times article calls “a sobering reminder that decades of efforts to bring human-produced emissions under control are faltering.”

Carbon dioxide is the most important heat-trapping gas in the atmosphere, and this concentration of the gas has not been seen on Earth for at least three million years. Scientists say this high level will likely cause massive climate changes and encourage rising sea levels.

But, as Pennsylvania State University climate scientists Richard B. Alley puts it: “If you start turning the Titanic long before you hit the iceberg, you can go clear without even spilling a drink of a passenger on deck. If you wait until you’re really close, spilling a lot of drinks is the best you can hope for.”

So, how can we help turn the tide and avoid this disastrous outcome?

Running more vehicle fleets on domestic clean fuel is vital to supporting clean air, not only today, but for generations to come. Fuels like propane autogas, natural gas, biofuels and hybrid-electric vehicle technology help protect the health of our environment by drastically reducing harmful greenhouse gas emissions compared vehicles that operate on gasoline or diesel.

Autogas is one of the lowest total carbon emissions fuels, with a 20 percent reduction in GHGs versus conventional fuels. For example, the City of Newport News in Virginia eliminates more than 11 tons of greenhouse gas emissions annually operating just  22 autogas fleet vehicles. Propane autogas is also one of the most cost-effective alternative fuel options for fleets, not only in terms of fuel price per gallon, but also in regards to the upfront cost of implementation. In fact, it’s actually possible to build 15 autogas stations for the price of just one CNG station and convert two light-duty vehicles to run on autogas for the price of just one light-duty CNG vehicle conversion.

Autogas is a widely available, American-made, clean-burning fuel that will help ensure clean air for our communities. Not only that, propane autogas is without a double the most viable fuel for fleets who want to reduce emissions and fuel costs without breaking the bank on expensive fueling infrastructure or vehicles. Cleaner air is within our grasp–it’s up to America’s vehicle fleets to get the ball rolling by switching to domestic clean fuel like autogas.

The New Year kicked off with good news for alternative fuel fleets: the “fiscal cliff” bill passed by Congress includes the extension of previously expired federal tax credits for alternative fuels and alternative fueling infrastructure. The rebates, which had expired at the end of 2011, have now been extended through 2013 and also made retroactive for the year 2012. Fleets that converted vehicles to clean fuel or installed an alt fuel station last year are in luck, and those that have been thinking about making the switch…read on!

One tax credit allows clean fleets to recoup 50 cents per gge (gasoline gallon equivalent) specifically for the alternative fuels propane autogas (LPG), compressed natural gas (CNG) and liquid natural gas (LNG). The other provides a 30 percent credit on fueling infrastructure for any alternative fuel, on up to $30,000 per facility.

Though propane autogas is already affordable for fleets to implement without federal funding [see our recent post “America’s most cost-effective and practical clean fuel succeeds despite lack of government support”], this is still great news in terms of encouraging the use of domestic alternative fuel in the U.S. transportation sector. Fleets that have already made the transition to clean fuel will recoup enough money to add even more alt fuel vehicles over the next year. For fleet operators that have thought about converting to an alternative fuel but worried about the upfront cost, these tax credits may just be the extra incentive (pardon the pun) they need to take that first step toward greening their vehicles and saving on fuel costs in the long run.

If you’re a fleet operator considering making the switch to alternative fuel in 2013, we encourage you to do your research to decide on the most practical fuel for your fleet. The Alternative Fuel Fact Briefs available on the Autogas for America website provide a side-by-side comparison of propane autogas versus natural gas electric vehicles and gasoline, so you can see how each fuel stacks up in the areas of cost, emissions reduction and overall viability.

Here’s to a greener 2013 for American fleets—happy saving!

The federal government is focusing on achieving higher fuel efficiency vehicle technology by implementing new CAFE standards that will nearly double vehicle fuel economy to 54.5 miles per gallon by the year 2025. While the new standards make exceptions for certain alternative fuel applications, propane autogas vehicles were overlooked. However, there’s already a movement among our nation’s fleets–the small businesses, law enforcement agencies, municipalities and transportation services out there–to adopt this clean, American-made fuel that’s affordable to implement and ready to use, today.

Propane autogas is gaining momentum with American fleets because it’s the most practical and cost-effective clean fuel on the market. Not only can autogas stations be implemented for a fraction of the expense of other alternative fuel infrastructure, they can also be built quickly and at no upfront cost to fleets. Autogas has averaged $1.45 less per gallon than gasoline over the past five years.

Proponents of other alternative fuels lobby the government for support to make their clean fuel technology viable, while thousands of fleet vehicles across the country are already saving money on fuel costs, and achieving a faster ROI, by converting to autogas.

Recent examples of U.S. autogas market growth include:

• multiple Texas school districts switching their buses to propane autogas through CleanFUEL USA, which recently announced more than 37 new or expanded contracts with Texas ISDs for autogas refueling infrastructure equipment.

• the Alliance AutoGas network expanding internationally to give Canadian fleets access to its complete autogas vehicle conversion and refueling program.

• major OEM manufacturer ROUSH CleanTech expanding its presence in America’s automotive capital of Detroit with a new 60,000 square foot facility to support the production of autogas systems for the new Blue Bird Vision school buses. ( CleanFUEL USA recently announced an upgraded new Detroit-area facility, as well.)

• new propane-autogas-powered fleets making headlines every day like the Sandy Springs, Ga., PD; the Lee County Sheriff’s Office; DHL; the City of Springfield, Ill.; and Veolia Transportation, which is converting 300 taxi cabs to autogas nationwide.

• states like Mississippi, which is running several public fleet vehicles on autogas, and Indiana, which is converting hundreds of government fleet vehicles to autogas and implementing 115 autogas stations across the state.

Despite autogas being the most cost-effective, easy-to-implement clean fuel, the popularity and government favoritism of CNG will remain an obstacle. According to a recent report from Pike Research, “even though [CNG] fuel is much more difficult (and more expensive) to handle than autogas, it looks as if CNG will attract the majority of the incentives from many governments around the world.” But whether or not natural gas lobbyists achieve continued favoritism among legislators, propane autogas will always have an advantage as the only practical clean fuel that fleets can already affordably adopt.

The bottom line is, the federal government may be ignoring the most viable alternative fuel on the market, but America’s fleets certainly aren’t.

Grand Junction, Co. had the best of intentions when it decided to invest in several natural gas-powered trash trucks. However, due to the large tank size required for CNG storage, the town’s trash trucks have had nearly two feet added to their length. Since CNG is less dense than liquid fuels, the size of the fuel tank must be increased in order to make up for lost range.

“Drivers of the new garbage trucks that run on compressed natural gas recently purchased by the city are unable to navigate some tight city alleyways, according to Grand Junction Public Works spokeswoman Kristin Winn.” About 160 residents used to be able to push their trash cans to the alley for pick-up, but now have to haul their cans to the front of their homes.

In response to a few complaints, the city has started offering elderly or disabled citizens the option of requesting help with their cans. Despite the problems, however, the city has plans to add two more CNG trash trucks to its fleet in the coming year.

As for trying to navigate the alleyways, the city is “…still kind of looking at this and modifying the trucks,” according to Winn.

Note: While it is true that natural gas vehicles offer about a 29% overall reduction in emissions versus gasoline engines, the article’s author overstated this figure when she said that they “produce almost no greenhouse gases.”
