A new comprehensive Life Cycle Assessment (LCA) by sustainability consultancy Sphera shows that the carbon footprint of aluminum cans made in North America has dropped by nearly half over the past three decades.
The Life Cycle Assessment of North American Aluminum Cans found that greenhouse gas emissions for aluminum beverage can production has dropped more than 40 percent since 1991 and 7 percent since 2012. Energy demand has declined by similar levels during this time period. These reductions have been driven largely by decreased carbon intensity of primary aluminum production in North America, lighter cans (which are 27 percent lighter per fluid ounce compared to 1991) and more efficient manufacturing operations.
