Join Julian Allwood of Cambridge University and the Low Carbon Materials Processing Group to learn about how one third of the world's carbon emissions are emitted by industry. Most industrial emissions relate to producing materials. Steel, cement, plastic, paper, and aluminium are the most important contributors. The industries that make materials are energy-intensive, so they have always been motivated to be efficient and have now reached a fantastic level of performance. However, the world's demand for materials is growing, and likely to double by 2050.
