Concrete and carbon uptake
How much carbon dioxide concrete can absorb Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us. In this episode, Hessam Azarijafari explains the extent to which concrete can absorb carbon dioxide over its lifecycle. In this episode, we cover: •[00:00] Introduction. •[00:56] Construction engineer Hessam Azarijafari introduces us to the recipe for concrete. •[01:41] He explains how concrete absorbs carbon dioxide throughout its lifespan, and why this absorption is important. •[02:52] Azarijafari talks about the background of the study. •[03:45] He describes the model built for the study and the data source. •[05:59] Azarijafari tells the study's results, including variation in absorption across sectors and between the US and Mexico. •[07:41] He compares this analysis with previous estimates of concrete carbon absorption. •[08:25] He explains the takeaways from this study for policymakers and the concrete industry. •[09:36] He lists the caveats and limitations of the study. •[10:19] Conclusion.
