The Restart Project report that the average mobile made this year will produce 35 kg of carbon emissions in manufacture, equivalent to 16 weeks of laundry.  And with around 1.9 billion mobiles sold a year that's the same as Austria's emissions.  They're asking us to make our phones last longer - even just 1/3 long could save the same as Singapore's annual emissions.  Demand better design and more efficient phones!
