I posted a rebuttal to this article as it implied everything was peachy keen.
It certainly is not the case at the present time.

Who?ll be the real change agent to force green innovations throughout the
marketplace? Surprise, it?s not EPA.
Instead, manufacturers are forcing their suppliers to go green, and those
suppliers will find themselves adopting eco-friendly business practices well
before EPA gets around to forcing these dramatic market changes.
That?s the take home in a new Frost & Sullivan analysis
<http://www.frost.com/prod/servlet/report-brochure.pag?id=D1CE-01-00-00-00> of
the electronics manufacturing industry and how it?s forcing its supply chain to
go green. And, this industry is making the switch to beef up its green
credentials without compromising its business needs and development. The
go-green push seems only win/win, according to Frost & Sullivan.
Some of the changes adopted by the electronics industry include switching to:
* lead-free solder and other electronic components
* halogen-free flame retardants, and
* products that are easier to recycle.
These changes enhance a manufacture?s greeniness. But more importantly, they
cut operating costs because eliminating reliance on hazardous materials
eliminates the costly regulatory liabilities associated with their use.
For example, by converting to lead-free solder, manufacturers no longer have to
deal with costly hazardous waste regulations that control disposal of lead
wastes. These changes save money for the facilities.
Electronics manufacturers are also adopting clean delivery and waste
minimization strategies, such as reducing packaging needed to ship a product.
These changes all contribute to reduce a company?s energy consumption, which
cuts costs and lowers related air pollutant emissions, particularly greenhouse
gas releases.

The use of consumer lead-free electronics in products whose life-cycle
includes operation in and through harsh environments, poses technical risks
that can lead to degraded reliability and reduced lifetimes. Quantification of
these technical risks within valid statistical confidence bounds remains a
significant gap. Further reliability data is needed on the performance of
lead-free solders in order to unite the existing prediction methodologies, and
provide acceptable modeling accuracy.
The spectrum of gaps that exist in the current body of knowledge on
Pb-free electronics is considerable, despite considerable research being done
to find a replacement for lead in tin-lead solder. As an example, it is a
proven fact that removal of lead from tin based solder (and all solders being
used today are tin-based) allows the growth of tin whiskers which short
electrical circuits. Without lead in the solders, the joints are more brittle,
more subject to fracture when subjected to mechanical stress (vibration and
shock). See http://nepp.nasa.gov/WHISKER/index.html Scientists do not yet
understand why lead suppresses tin whisker growth so the search for an
acceptable replacement remains elusive.
Until a replacement is found, there remains unacceptable risks imposed
by lead-free electronics in high reliability, high-performance applications,
especially in extreme environments such as aircraft, submarines, and military
weapon systems. Until the risks become fully articulated, quantified, and
bounded by hard numbers to ensure viable product design, manufacturing, test,
delivery and maintenance and longevity of such products at an affordable cost,
the use of commercial off-the-shelf lead-free components (COTS) cannot occur.
It is a goal the aerospace, defense and high performance/high
reliability industries are working to achieve but it will take many more years
of research to reach.
