The average mobile made this year produced 35 kg of carbon emissions to manufacture, equal to 16 weeks of laundry. Sound small? Consider that 1.9 billion mobiles will be sold in 2015, approximately 60 per second. Their total carbon footprint in manufacture is equal to Austria’s annual carbon footprint. All of us can help reduce the impact of mobiles with one simple step: simply use them for longer. If we used every phone manufactured this year for only 1/3 longer, we could prevent carbon emissions equal to Singapore’s annual emissions.
