Connecticut needs to be ‘greening’ its transportation system

This chart by the Connecticut Department of Energy and Environmental Protection, shows the relative ozone levels in July across the state.

Do you know how bad Connecticut’s air quality is?  According to the American Lung Association, all of our state’s counties got a grade of “F” when it comes to ozone.

On hot, summer days the sun’s rays combine with auto, truck and power plant exhausts to create an invisible blanket of ozone over our state.  When it combines with fine particulate matter it turns into a grayish haze, making breathing difficult.

Sure, we can blame states to our west whose pollution blows our way, including those “clean coal” meccas of West Virginia and Ohio.  But before we point fingers, maybe we should consider what we are doing ourselves to worsen the problem.

Think of this next time you’re in bumper-to-bumper traffic on I-95 or the parkways.  Metro-North mostly runs its trains on electricity, but its diesels are downright filthy as are local buses, though many fleets are converting to natural gas or electric operation.

Even shipping by water contributes to pollution, though you hardly think about it as you’re breathing in the brisk air of Long Island Sound.  So it was great to read recently that Connecticut will soon have its first “hybrid” cross-Sound cargo vessel, “Harbor Harvest,” named after the natural food store and café in Norwalk.

The 65-foot, aluminum catamaran will carry everything from fresh produce to craft-brewed beer back and forth between Connecticut and Long Island.  The $2.8 million dollar vessel will charge its batteries using shore power for the 45 minute crossing.  Its owners estimate their cargo will take one or two trucks off of I-95 by cutting the travel time in half.

Mind you, the project wouldn’t even be possible were it not for a $1.8 million federal grant which the owners hope will keep them running for a couple of years.  Then we’ll see if it’s economically viable.  One shipping veteran on the coast tells me that’s “possible but not probable.”

Not that one little boat, displacing two trucks a day, is going to make our air breathable again.  But it’s a start.

Meanwhile in California, the shipping industry is “going green” on a massive scale.  The twin ports of Long Beach and Los Angeles are the two busiest ports in the US, handling 400 ships a year.

To reduce pollution, the ports introduced a speed limit of 12 knots for ships as far as 40 miles from the docks.  Those vessels used to constantly keep at least a generator running to power the vessel in port, but now they too are “plugging in” when they tie-up to unload containers and freight.

Here’s an astounding statistic:  Allowing just one container ship to use shore-power for a single day is the pollution-reducing equivalent of taking 33,000 cars off the road for that day.  That’s a major impact on air quality.  But it’s only the beginning of the needed “greening” of this transportation hub.

Containers offloaded from the vessels will soon be moved around the port on electric trucks, then mounted on railcars and carried away by fuel-efficient (but still very dirty) diesel-pulled trains and 16,000 long-distance (equally dirty) trucks.  So there’s still much to be done.

We worry so much about traffic and getting where we must, quickly and safely.  Maybe we should also think about how our transportation choices effects on our health.
