More efficient use of materials in residential buildings and cars could save enormous amounts of greenhouse gas emissions by 2050: 20 to 52 gigatons of CO2 equivalents for residential buildings and 13 to 26 gigatons of CO2 equivalents for cars, which amounts to up to two-thirds of current consumption. This is the conclusion reached by a research team led by Dr. Stefan Pauliuk, Assistant Professor of Sustainable Energy and Material Flow Management at the University of Freiburg.
