Zero-emissions vehicles already exist in two types: battery-powered vehicles and
hydrogen fuel-cell vehicles. Emission standards were enacted, and air pollution
levels started falling again. That's still not trivial, but manufacturers who
change their designs to better account for the end-of-life recycling/disposal
requirement will make their operations more efficient and gain an advantage.
When we speak of reducing air and water pollution, what we're really talking
about is innovation in design. Rohner Textil, a Swiss textile mill, was a
typical high-pollution plant, until they hired a consulting firm that helped
them get into green design and green manufacturing.." One would think that such
a big change would be hugely expensive and damaging to Europe's manufacturing
economy, but it's estimated that the potential impact to sales is only 1% to 4%.
Ideally, a manufacturing process should be designed so that every byproduct is
useful again within that process or is useful as an input to some other process.
Still, we now see that our goal of garnering a tremendous reduction in vehicular
air pollution is possible, given technology, time, and will.. These designs,
however, still have enough kinks to be worked out that they are not practical
for widespread implementation at this time.We've come to accept the assertion
that some level of air pollution and water pollution is OK; or, if not OK, that
it's necessary to allow a modern lifestyle.
At some point, as more and more cars
were added, the cumulative amount of air pollution they produced got to be
enough that even when diluted in the larger volume of air in a given region, the
air-pollution levels started being high enough to cause health problems. That
would be a very obvious way for a car owner to assess whether the exhaust from
his or her car was "clean enough," and a consumer would not buy a car that
allowed carbon monoxide, sulfur dioxide, nitrous oxides, and other pollutants
into their immediate breathing space.
When there was only one car on the planet,
the amount of air pollution it produced was irrelevant to the cleanliness of the
total volume of air. Green design, green manufacturing, and green chemistry all
work to move from toxic inputs to ecologically sound inputs, and they design
processes so that waste products are less toxic and are rerouted back into
productive use. That is a paradigm shift relative to what we have been used to.
If most of the chemicals suddenly weren't available for use, would the Rohner
Textil mill still be able to operate and produce clothes that people want to
buy? But is it realistic to think that we could eliminate toxic chemicals from
manufacturing and that we can make things in an industrial setting without
producing water pollution? Yes. The CEO is perfectly willing to drink it! At a
time when most textile operations have fled the West to the cheap labor markets
of the East, Rohner Textil continues to do just fine in Switzerland - because of
their switch to green design/green manufacturing.This has forced manufacturers
to rethink their approach to product design.
Although waterways in the US and
other Western countries have gotten cleaner since the bad ol' days of the 1960s,
they are still not nearly clean enough. But is this true? We all breathe the air
that our tailpipes pump pollution into, but the pollutants are diluted because
the volume of air they occupy is larger than the volume of air in our immediate
breathing space. In fact, the waste water from their process is as clean as
Swiss drinking water. Europe has recently enacted laws that require
manufacturers to take responsibility for the safe disposal of electronic
equipment. We all like to think that the clothes we wear are non-chemical in
nature, but the typical clothing manufacturing plant uses lots of chemicals -
yes, fixers, etc - and the output is not what you'd call clean.
Now, rather than
just thinking "How can we design this to be attractive, functional, and
inexpensive," they also have to add "and cheap to recycle or dispose of
properly. Another "zero emissions" example can be formulated for industrial
water pollution. So, back to the idea of designing a car so that it's OK to take
the tailpipe and put the exhaust directly back into the passenger compartment.

anyway, wouldn't you be willing to pay 1%-4% more
for goods (or have 1%-4% less stuff over your lifetime) to be able to live in a
world with far less pollution? Life-cycle design, a concept that is part of
green design, looks at the product itself to make sure that when its useful life
is over, it can easily be disassembled and its components put back into the
But as we keep adding more and more cars - with lower-mileage,
higher-polluting vehicles comprising a larger portion of them - and as we
continue driving more miles per person - advances in air-pollution-control
technology have started losing some of their effectiveness in terms of how clean
the air is overall. In this way, there is no pollution to dispose of. But is
that just a tail-pipedream? No. In the US, for instance, more than a third of
our surface waters are still beset by water pollution and are considered unsafe
for fishing or swimming - let alone drinking.
As an example, let's talk about a
Swiss textile mill where this was done. Though they had to eliminate many toxic
chemicals and change some of their manufacturing processes, Rohner Textil
continued making fabric profitably and avoided the costs associated with filling
out government reports on stored toxics and waste-water pollution - they were
that clean. >>
