Yard Art - funny! I am sure Nissan engineers would take exception to this comparison however true.

We find it amazing that so many people are focused on EV's citing the main reason as they have no emissions, when the significantly greater mining and mineral refining operations to manufacture an EV off-sets the zero emissions factor for the first 15K-25K miles. Then when the vehicle's battery needs to be replaced, the vehicle takes another major emissions hit. Then due to the short life expectancy of the EV - typically 7 years or less - the vehicle is recycled at probably 1/2 or even 1/3rd the life cycle of an advanced diesel vehicle. While the life cycle emissions of an EV do not exceed those of an advanced diesel vehicle running B100, it is closer than most might believe - probably within 50%. EV's are far from a perfect solution.

As our complete transportation solution includes the planting of over 10,000,000,000 10'-14' tall trees in the US alone, our efforts also claim these advantages...

Reduction of Other Air Pollutants Via Trees:

* Trees also remove other gaseous pollutants by absorbing them with normal air components through the stomates in the leaf surface.
* Some of the other major air pollutants and their primary sources are:
o Sulfur Dioxide (SO2)- Coal burning for electricity/home heating is responsible for about 60 percent of the sulfur dioxide in the air. Refining and combustion of petroleum products produce 21% of the SO2.
o Ozone (O3) - is a naturally occurring oxidant, existing in the upper atmosphere. O3 may be brought to earth by turbulence during severe storms, and small amounts are formed by lighting. Most O3 - and another oxidant, peroxyacetylnitrate (PAN) - come from the emissions of automobiles and industries, which mix in the air and undergo photochemical reactions in sunlight. High concentrations of O3 and PAN often build up where there are many automobiles.
o Nitrogen oxides - Automotive exhaust is probably the largest producer of NOx. Oxides of nitrogen are also formed by combustion at high temperatures in the presence of two natural components of the air; nitrogen and oxygen.
o Particulates are small (<10 microns) particles emitted in smoke from burning fuel, particular diesel, that enters our lungs and cause respiratory problems.
* There is up to a 60% reduction in street level particulates with trees.
* In one urban park (212 ha.) tree cover was found to remove daily 48lbs. particulates, 9 lbs nitrogen dioxide, 6 lbs sulfur dioxide, and 2 lb carbon monoxide ($136/day value based upon pollution control technology) and 100 lbs of carbon.
* One sugar maple (12" DBH) along a roadway removes in one growing season 60mg cadmium, 140 mg chromium, 820 mg nickel, and 5200 mg lead from the environment.
* A total of 300 trees can counter balance the amount of pollution one person produces in a lifetime.

EV's and Hybrids are not our Future etcgreen.com
