Getting greener, but not there yet

Abstract:

Green computing or green IT, refers to environmentallysustainable

computing

The study and practice of designing, manufacturing, using, and disposing of

computers, servers, and associated subsystems

The aim of green computing are similar to green chemistry; reduce the use

of hazardous materials, maximize energy efficiency during the product's

lifetime, and promote the recyclability or biodegradability of defunct

products and factory waste

Greenpeace congratulates the electronics industry on making progress the

many technical hurdles it has been facing - but we also show that the

industry hasnt finished finding green solutions just yet

Further room for improvement:

While Greenpeace applauds the progress that hasbeenmade, there aremany hurdles the industry has yet

to overcome.

Throughout a products lifecycle - frommaterialextraction to production, and fromconsumer use todisposal electronic products have the potential to

impact human health and the environment

Survey criteria:

The leading manufacturers of desktop computers ,notebooks, net books , computer monitors , mobile phones ,smart phones as well as televisions were directly invited tosubmit their greenest products via an assessment form that wasprovided

This was done not only to ensure that the companiescould select their highest performing products

If a company submitted more than one product in acategory we chose the highest-scoring device for inclusion inthe report


5/18

The products submitted were assessed against four broadgroups of criteria:

Use of hazardous chemical substances

Power consumption of the products

Product lifecycle

Innovation and marketing


6/18

Use of hazardous chemical substances:

Including polyvinyl chloride (PVC),brominates flame retardants (BFRs),antimony and its compounds,

phthalates, beryllium and itscompounds and a number of otherchemicals. The use of exemptions to

the EU RoHS(Restriction of Hazardous Substances)

directive4 was also taken


7/18

Power consumption of the products

Products were assessed by comparing them with the EnergyStar standards of the US Environmental Protection Agency.

The more a product exceeded the standards, the more pointswere awarded

It has to be noted that, because of new Energy Star standards,the results cannot be compared to previous Greenpeacesurveys.


8/18

Product lifecycle

Including criteria such as the percentage of recycled plasticused in the product

The length of warranty and the availability of replacement

parts after production ceases.

Products that were more upgradeable or have goodproduct/battery price ratios were also awarded

As were take-back programmers for products when thenare disposed of by the user.


9/18


Resulted in points awarded for comprehensive data forthe energy taken to produce a product (from mining toshipping to retailers)

The visibility of the product on company websites as wellas other special innovations and features a product mightpossess.

It is very important to recognize that a number of thecriteria are specific to the product categories and that it isnot possible to compare products across differentcategories.

Products submitted by each company:


11/18

Main findings

here are three main findings:

Significant reductions in the use of hazardous chemicals

Exceeding energy efficiency standards.

Product lifecycle responsibility must improve.


12/18

Significant reductions in the use of hazardous chemical:

More products than ever before are PVC-free and BFR-free

The use of phthalates, as well as beryllium andantimony and their associated compounds, are beingeliminated in every product category.

Although the previous survey showed that the use ofRoHS exemptions could be drastically reduced

we have yet to see this progress in the industry.


13/18

Exceeding energy efficiency standards

Almost all products meet or exceed the current EnergyStar standards established by the US EPA.

Electronics companies seem to put much more effort inimproving the energy efficiency of their products rather thanassessing thoroughly (and reducing) the embedded energy

That is, the energy spent during the production of eachproduct.


14/18

Product lifecycle responsibility must improve.

Lifecycle management is still the weakest point ofelectronic products

With very little use of recycled plastic, a variety of take-back practices (generally improving) and little marketingefforts

We did find that companies are becoming moretransparent in the amount and type of product informationthey provide to customers


15/18


Energy during production:

The energy used to manufacture a product is as important toinvestigate as the energy it takes to power a device duringconsumeruse. Reducing energy during production plays an importantrole inreducing the impact on natural resources and the climate.

Unfortunately .The energy used to manufacture a product is asimportant To investigate as the energy it takes to power adevice during consumer use. Reducing energy duringproduction plays an important role in reducing the impact on

natural resources and the climate.


16/18

Other innovation and features

Green innovations going beyond common practices wereawardedwith additional points.

These included, for example, arsenic-free glass, waterbornepaint, solar panels, avoiding volatile organic compounds orproducing products that are extremely durable.

Moreover, companies that have an independent third partyverify the absence of hazardous substances were alsoawarded
