do some simple math to check out these claims. 32 gal gas gives 112 kg CO2 ,112kg equals 50.909 lbs. divide 50.909 by 32gal to get 1.59lbs CO2 per gal gas. then multiply 584000 gal gas by 1.59lbs CO2 per gal gas which is 928560lbs CO2. how did it get all the way up to 35 million?

Great Post. I’m sure that the manufactures of the phones don’t help the matter by supplying cheap disposable phones. I have had the same Iphone for one and a half years and its quality and robustness combined the ability to upgrade its software means it will last 4x longer than cheap disposable phones.
But unfortunately quality costs.

i would say that recycling these phones would actually consume more energy than it would save. and charging your phone half as often would most likely leave it dead twice as often too. interesting image but mathematically flawed. Too bad they didn’t mention their sources for this. that would have been nice to be able to verify the accuracy of it.

Don’t we need data comparing cell phones to land lines before we can decide which option is greener?

the answer should be to make phones that are longer-lasting… make them upgradable so people use them longer.

I’ve seen stats claiming 600 million cars on the road in 1997, worldwide. If we took the estimated half million cars off the road (even assuming no more/new cars were purchased in the last 12 years) we would solve 0.00083% of the problem. I’d rather we all found a way to figure out how to make a REAL positive impact on the world.

Surely it is possible to design chargers that switch off if the phone is fully charged or if is disconnected from the charger. That would save 2.05Billion watts!
