Carbon Dioxide Emissions When Cars Get Built

Carbon dioxide emissions of new vehicles start before you first drive one.

A 2004 analysis by Toyota found that as much as 28 percent of the carbon dioxide emissions generated during the life cycle of a typical gasoline-powered car can occur during its manufacture and transportation to the dealer; the remaining emissions occur during driving once its new owner takes possession.

An earlier study by Seikei University in Japan put the prepurchase number at 12 percent.

If you are a very low mileage driver you can probably reduce your environmental impact by driving an old car.

I'd like to know what the energy cost is for making NiMH and Li ion batteries for hybrid, pluggable hybrid, and pure electric cars. How many miles do you have to drive each kind to achieve a net reduction in carbon emissions as compared to driving the same number of miles with a conventional internal combustion engine car?

A shift to pluggable hybrid and pure electric vehicles combined with a shift to nukes, solar, wind, and geothermal electric power generation is the way to most drastically reduce fossil fuels usage. Throw in a shift to heat pumps for heating and our use of fossil fuels would plummet.

How much CO2* produced just by all those auto-workers driving to work each day? And then home again? Add that lot to the CO2 released during manufacture and delivery of those nice new "economy" cars, hybrids and electric cars that people are supposed to purchase to replace their "aging gas guzzlers".

It's more environmentally friendly and, as it happens, economic to keep the old "guzzlers" on the road as long as you can. Those oldies cost way less to purchase (second hand is more economical as you have beaten the depreciation curve; some hick fool paid for depreciation, dealership commissions, finance rorts and most of the government theft overheads already), operate, repair and maintain, insure, obtain components (you can even get parts second hand, make 'em or have them made- try doing that with some electronic computer feature/gadget infested heap) and they are way nicer to drive. They don't look weird (like many of the new Bunglified cars do). Forget about the fraud of "cash fo' clunkers". Repair, reuse, modify, improve, update what you already have. Recycling by scrappage and buying new is the last solution anyone should be relying on.

By the way, buying new is for people who already paid off their houses..... for cash. Buying new is for people who already have their superannuation solidly sorted (and not in a fund). Buying new is for the debt free. The rest of you shouldn't even be thinking about buying new vehicles. You can't afford to. Not if you want to avoid state triage administrators for example. Still, most are sucked into the get a new car every three years on tick routine. And there are those who engage in buying new, as it is their intention to operate on the basis of a lifetime of debt. How's your credit sucker?

*I assume that the context of the story was that CO2 emission must be reduced (an opinion that relies on a fraud in which no sane person can believe).
