“Examples of quantities of "e-waste" generated should reference global versus regional figures (i.e. paragraph 8). The 2009 UNEP Solving the E-waste Problem (StEP) report, Recycling - From E-waste to Resources indicates that the amount of global "e-waste" generated each year is estimated to be around 40 million tons.”
