A smartphone uses nearly 13,000 litres of water and 18 square metres of land, the study found, with two fifths due to pollution during manufacturing and assembly. A pair of leather boots requires 14,500 litres of water, but this rises to 25,000 litres where leather tanneries dump untreated chemicals into the environment, according to the report. A 100g bar of chocolate uses 2.5m² of land and 1,400 litres of water, while a t-shirt requires four litres of water and just over 4m² of land, the research revealed.
