"Aluminium accounts for 2% of all human-caused greenhouse gas emissions each year"
"Aluminium is often referred to as the ‘green metal’, thanks to its high strength-to-weight ratio, long lifespan, corrosion resistance, and the fact it can effectively be recycled forever, melted down and reformed without losing quality.
But the environmental credentials of the versatile material are severely let down by its carbon footprint. The aluminium sector generates around 1.1bn tonnes of CO2 per year, largely because of reliance on energy-intensive smelters."
