Earth Day Campaign - 41 Reasons to Plant a Tree for Your Book: Reason no. 7

We continue today with our Earth Day campaign - 41 Reasons to Plant a Tree for Your Book, where we share with you 41 reasons provided by readers in celebration of the upcoming 41st anniversary of Earth Day.

With more than 180,000 trees planted so far on behalf of readers, authors and publishers working with Eco-Libris, it's no surprise that we think planting trees to green up books is a great idea.. But we also want to hear what readers think about it and why they believe planting trees for their books is a good idea.

So for 41 days until Earth Day, we publish here the 41 best replies we receive, one reply a day. All replies are gathered and presented on the campaign's page.

Reason no. 7:

Though I believe it's important to not only read but also preserve the real, physical book, I don't believe it's right to fell old growth forests to fill my shelves. Also, as an author, I want people to have the option to read my new book in the form that has served humans well for centuries. That's why I support Eco-Libris. Long live books and forests! - Kelly

Thank you Kelly for sharing with us your thoughts on planting trees for your book!

Kelly, just like all the other readers whose replies we'll publish, is winning one of the great 41 prizes we give away on this campaign, courtesy of our partners. Winners can choose their prize from a great list of gifts including audiobooks from Simon & Schuster Audio (such as The Half Life by Jennifer Weiner, American Assassin by Vince Flynn and Essence of Happiness by the Dalai Lama) and great books, like Planet Home by Jeffrey Hollender, Spit That Out! by Paige Wolf, Menu Dating by Tristan Coopersmith and The Healthy Home by Dave Wentz and Dr. Myron Wentz. You can see the full list of the prizes on the campaign's page.

Every day we'll give further details on one of the prizes. Today we present you with the audiobook American Assassin by Vince Flynn:

American Assassin by Vince Flynn - #1 New York Times bestseling author Vince Flynn introduces the young Mitch Rapp on his first assignment, a mission of vengeance that made him a CIA superagent— and a terrorist's worst nightmare.

Two decades after the Cold War, CIA Operations Director Thomas Stansfield must prepare his people for the next conflict. The rise of Islamic terrorism is coming, and it needs to be met abroad before it reaches America's shores. Stansfield directs his protÉgÉe, Irene Kennedy, and his old colleague, Stan Hurley, to form a new group of clandestine operatives—men who do not exist—who will work outside the normal chain of command. Kennedy finds the ideal candidate in the wake of the Pan Am Lockerbie bombing terrorist attack. . . .

Among the thousands of family and friends grieving the victims is Mitch Rapp, a gifted college athlete, who wants only one thing: retribution. Six months of intense training prepare him to bring the war to the enemy's doorstep, and he does so with brutal efficiency, leaving a trail of bodies from Istanbul and across Europe, to Beirut. But there, the hunter becomes the hunted: the enemy has prepared a trap, and the American assassin will need every ounce of skill and cunning if he is to survive the warravaged city and its deadly terrorist factions.

If you want to participate in the campaign, we still have some spots available so please send us your reply, either by adding a comment here or sending it to info@ecolibris.net. We look forward to hearing from you.

Comparing between the iPad and the iPad 2 from a green perspective

Last week the environmental report of the iPad 2, where we learned that its carbon footprint is 105 kg CO2e, a reduction of 19.2% comparing to the footprint of the first model.

On Tuesday we started to look into the new report and showed what it means in terms of breakeven point with paper books. Today, in the second part of our analysis, we try to find out what the real "green" differences between the two models of the iPad are.

We'll look at each of the components of the life cycle analysis that Apple did to determine the carbon footprint of the iPad and the iPad 2 - production, transport, customer use and recycling. We'll also look into other specifications that Apple emphasizes on its report.

Production:
Carbon footprint of the iPad - 75.4 kg CO2e
Carbon footprint of the iPad 2 - 63 kg CO2e
Change: -16.4%

The iPad 2 is thinner and lighter than the original iPad. In terms of materials Apple mentions that "iPad 2 is even more material efficient than the original iPad, consuming up to 18 percent less material. The chart below details the materials used for iPad 2."

Here you can see the materials used for the iPad 2 (source: Apple's report):

And here are the materials used for the first iPad (source: Apple's report)

Here's a comparison of the data presented in these graphs (weight, in grams):

	iPad	iPad 2	Change
Display	155	140	-9.7%
Plastic	55	17	-69.1%
Other metals	40	25	-37.5%
Circuit boards	45	38	-15.6%
Glass	155	105	-32.3%
Battery	155	130	-16.1%
Aluminum	125	135	8.0%

It's interesting to see that the biggest changes are with the plastic and other metals and also that unlike the other components, the usage of aluminum actually increased in the iPad 2 in 8%. I believe that the efficient use of materials is the main reason for the reduction in the production's footprint. I also believe that this is also a place where Apple actaully saved money while reducing its product's carbon footprint.

Transport:
Carbon footprint of the iPad - 14.3 kg CO2e
Carbon footprint of the iPad 2 - 10.5 kg CO2e
Change: -26.6%

There's no explanation in the report where this reduction is coming from. One option this reduction is due to further efficiency in packaging - iPad 2 retail packaging consumes 51 percent
less material, which allows "up to 38 percent more units to be transported in an airline shipping container compared with the original iPad".

Apple also mentions that"the packaging for iPad 2 is highly recyclable. It uses corrugated cardboard made from a minimum of 28 percent post-consumer recycled content, and molded fiber made entirely from recycled content."

On the report of the first iPad, Apple wrote: "The packaging for iPad is almost entirely recyclable and uses corrugate cardboard made from a minimum of 33 percent post-consumer recycled content. In addition, its packaging is extremely material efficient, allowing more units to be transported in a single shipping container. "

As you can see, the percentage of post-consumer recycled content in the corrugated cardboard actually dropped from 33 to 28, although with the iPad 2, Apple mentions that the molded fiber made entirely from recycled content whereas in the first report it doesn't mention this fiber at all.

Alternatively, maybe Apple started using hybrid trucks?

Customer use
Carbon footprint of the iPad - 39 kg CO2e
Carbon footprint of the iPad 2 - 30.45 kg CO2e
Change: -21.9%

Apple is presenting in the reports information on the energy efficiency usage, which should be the most relevant component to this part:

Energy efficiency in the iPad 2:
iPad 2 uses power-efficient components and software that intelligently manages
power consumption. In addition, the iPad 10W USB Power Adapter outperforms the
stringent requirements of the ENERGY STAR specification for external power supplies.
The following table details the power consumed by iPad 2 in different use modes.

Power Consumption for iPad 2 (Wi-Fi + 3G)
Mode 100V 115V 230V
Sleep 0.46W 0.41W 0.45W
Idle—Display on 3.10W 3.08W 3.16W
Power adapter, no-load 0.07W 0.07W 0.09W
Power adapter efficiency 80.9% 80.8% 79.9%

Energy efficiency in the first iPad:
iPad uses power-efficient components and software that intelligently manages power consumption. In addition, the iPad 10W USB Power Adapter outperforms the stringent requirements of the ENERGY STAR specification for external power supplies. The following table details the power consumed by iPad in different use modes.

Power Consumption for iPad (Wi-Fi + 3G)
Mode 100V 115V 230V
Sleep 0.42W 0.43W 0.41W
Idle—Display on 2.97W 2.96W 3.04W
Power adapter, no-load 0.07W 0.07W 0.09W
Power adapter efficiency 80.9% 80.8% 79.9%

I have to admit that I am not sure yet how this data, showing relatively modest power consumption reductions is translated into a 22% reduction in the carbon footprint of customer use. Did I miss something here?

Recycling:
Carbon footprint of the iPad - 1.3 kg CO2e
Carbon footprint of the iPad 2 - 1.05 kg CO2e
Change: -19.2%

In both cases Apple offers the same description:
Through ultra-efficient design and use of highly recyclable materials, Apple has minimized material waste at the product’s end of life. In addition, Apple offers and participates in various product take-back and recycling programs in 95 percent of the regions where Apple products are sold. All products are processed in the country or region in which they are collected. For more information on how to take advantage of these programs, visit www.apple.com/environment/recycling/.

Strangely, if you go to this webpage, you will find that Apple has no mention of the iPad there, but only computers, displays, iPods and mobile phones. Even if we assume that the iPad has similar recycle offering as the iPod (and I have to say I'm not so sure about it), it's still far from being convenient or attractive - you can either send your old device by mail or bring it to one of Apple's stores and get 10% discount when purchasing a new one. So the bottom line is that Apple, even though it minimize the material waste by using materials more efficiently still doesn't make a real effort to make sure the first model or the second model of the iPad won't end their life eventually in the landfill.

Apple's commitment to the environment:
There's an introduction to the report where Apple is emphasizing its commitment imporving the environmental performance of its products. This part (see below) hasn't changed and the text in the iPad 2 report is identical to the text in the iPad report.

Apple believes that improving the environmental performance of our business starts with our products. The careful environmental management of our products throughout their life cycles includes controlling the quantity and type of materials used in their manufacture, improving their energy efficiency, and designing them for better recyclability.

Restricted substances:
Comparing between the two reports, we find this part identical. In both cases Apple mentions that "
Apple has long taken a leadership role in restricting harmful substances from itsproducts and packaging. As part of this strategy, all Apple products comply with the strict European Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, also known as the RoHS Directive. Examples of materials restricted by RoHS include lead, mercury, cadmium, hexavalent chromium, and PBB and PBDE brominated flame retardants (BFRs)."

According to the reports, both the iPad and the iPad 2 go even further than the requirements of the RoHS Directive by incorporating the following more aggressive restrictions:
• Mercury-free LED-backlit display
• Arsenic-free display glass
• Brominated flame retardant (BFR)−free
• Polyvinyl chloride (PVC)−free

General green specs:
Apple is providing a summary of the "green" specs in each report under "Environmental Status report". This report is identical for both models and include the following:

• Arsenic-free display glass
• Brominated flame retardant-free
• Mercury-free LED backlit display
• PVC-free
• Recyclable aluminum and glass enclosure
• Power adapter outperforms strictest global energy efficiency standards

And finally, here's a summary of the changes in the carbon footprint of each component:

	iPad	iPad 2	Change
Production	75.4	63	-16.4%
Transport	14.3	10.5	-26.6%
Customer use	39	30.45	-21.9%
Recycling	1.3	1.05	-19.2%
Carbon footprint:	130	105	-19.2%
