In the USA the green phrase is huge,every large corporation claims to be green. Example walmart when you hit there property-deliver, a large sign says no idling,a local law code on the sign, says there a partner with clean air,etc. There,s alot of procedures at walmart, all customers-shippers. You are not allowed to idle for heat or ac, no matter what the temp. over 100 or -10, peta has alot of power, if you have a pet in the truck you used to be able to idle, but if your 3 yr,old kids in the truck your not,well now you can,t idle,at all. The goverment put pressure on states to pass no idling laws, the fines are diff. in all the states, average fine 1,000 bucks, local cops go to truck stops and put the ticket on your truck,they know you can,t get back and fight it in court,easy revenue for towns. The funny thing is 08,09 trucks palute less than a car and 2010 trucks the exhaust is cleaner than the air you breath. I barrely touched on the clean air act, the bottom line is it cost more to ship products because the new trucks are so restricted they get worse fuel mpg,break down constantly, weigh more-haul less-need more trucks, and cost much more for the epa mandated engines, all these cost are figured in with the freight bill and the general public pays more for there goods. Obama passed a carbbtax, if your co. polutes it,s taxed, when that kicksin everything goes up, all goods shipped,enjoy the good times now. They could easily tax 2-st. riders, tax the companys that make the 2-st. oil,then they pass the fee to the buyer,and then it,s 35.00 per quart, sounds crazy but, that,s nothing comparred to the trucking industies hit.
