Rob a star engineer asked me to calculate the imputed carbon
tax to a consumer buying various cars.
As a base let’s assume the motorist wants safe, reliable,
and affordable transportation. The
motorist can buy a 2015 Toyota Corolla for MSRP of $17,500 and it will get 32
MPG. Let’s assume the car lasts 10 years
and goes a distance of 150,000 miles. At
22.5 pounds of CO2 well to wheels we have the motorist emitting 52.73 tons of
CO2 over the ten years.
The motorist can upgrade to a Prius and achieve 50 MPG and
only emit 33.75 tons of CO2 over the same distance in the same ten years. This saves the planet approximately 19 tons
of CO2 emissions. The MSRP of the Prius
is $24,200. The added $6,700 paid
divided by the 19 tons of CO2 means the motorist paid a carbon tax of $352.92
per ton of CO2 saved.
This is a very simplified analysis as the battery pack on
the Prius required some primary energy to fabricate the pack but for now let’s
assume the carbon footprint to produce a Corolla is the same as a Prius.
Next the motorist could have bought a plug in Prius. The MSRP is $29,900, this is $14,400 more
than the base Corolla. The MPG is 50 on
gasoline and let’s assume that one quarter of the miles are driven on US Average
Grid power with the grid emitting 0.55 tons per megawatt hour. Doing some tedious math we get the same
150,000 miles driven over ten years the Plug in Prius will emit 32.53 tons of
CO2. The carbon tax for buying the plug
in Prius versus the Corolla is $712.76 per ton of CO2 saved.
Next the motorist could have bought a Nissan Leaf. With a MSRP of $30,585 this car is $13,085
more expensive than the Corolla. Using
US average grid emissions the Leaf will have 28.88 tons of CO2 emissions over
the 150,000 miles. For this purpose we
will not add the CO2 emissions to fabricate the battery and therefore at a
minimum the carbon tax to buy the leaf over the Corolla is $548.42 per ton of
CO2. As you and I as taxpayers gave the
Leaf owner $7,500 to buy the wrong car we got taxed at $314.34 per short ton of
CO2 emissions saved.
For comparison one can buy a US ton of carbon offsets in
Europe for between $7 and $8 per ton of CO2.
None of these cars make any economic sense. Go out and buy a Corolla. It is a great car and probably will last long
beyond 150,000 miles. The Leaf will turn
brown and may not be compostable after 10 years.
Good comparisons. This shows the futility of buying battery-powered cars. The biggest loser is the tax payer.

Prof Rust the problem is that the department of entropy is clueless and let's the administration pretend we have an energy policy. CO2 emissions have grown in the last two years despite Alfed E New Man Moniz being on the job.
