Humans use around 90 billion metric tons of materials every year, creating about ⅓ of total global greenhouse gas emissions. Which materials produce the most emissions? You might be surprised.
In this episode of TILclimate (Today I Learned: Climate), MIT professor Elsa Olivetti joins host Laur Hesse Fisher to talk about materials, or as Prof. Olivetti calls it, “the study of stuff”. Prof. Olivetti explains where these emissions come from and how to reduce emissions and waste in our manufacturing.
Prof. Olivetti is the Atlantic Richfield Associate Professor of Energy Studies in the Material Science and Engineering Department at MIT. Prof. Olivetti focuses her research on developing strategies to make materials and manufacturing more efficient, inexpensive, and environmentally-friendly.
