A team led by @MIT_CEE research scientist Hessam AzariJafari developed a new analysis that provides the first national, bottom-up estimate of cement’s natural carbon dioxide uptake across buildings and infrastructure. news.mit.edu/2025/how-cemen…

Our recently published paper on the #PNAS bottom-up analysis of #carbon #uptake at the #national level: pnas.org/doi/abs/10.107…

##Cement in buildings and infrastructure absorbs over 6.5 million metric tons of CO₂ annually in the U.S., offsetting about 13% of cement manufacturing emissions through natural carbonation. @MIT @PNASNews doi.org/hbft8p techxplore.com/news/2025-12-c…

Cement is not just a source of CO2: it also quietly sequesters it over its lifetime. But how much? And how does that change across contexts? Different opinions and feelings, but read our approach @PNASNews pnas.org/doi/10.1073/pn… #cement #carbonation #uptake #CO2 #concrete

On 5/29, 11am, join Drs. @hessam_aj, Soroush Mahjoubi, and Miaomiao Zhang for a webinar discussing our research on the emissions impacts of concrete's inherent strength variability, the necessary practice of overdesign, and prescriptive specifications. mit.zoom.us/webinar/regist…

#Concrete is typically designed stronger than required to account for natural variability. By narrowing this gap, we can cut excess material use and save more than 80kg CO₂e per cubic meter of concrete. Learn more: cshub.mit.edu/wp-content/upl…

Join Dr. Haoran Li and Dr. @hessam_aj on 2/27 11am ET as they discuss how the recently published Streamlined #Pavement #LCA Tool enables pavement design optimization and refines long-term performance forecasting. mit.zoom.us/webinar/regist…

Natural hazards are expected to cost the U.S. ~$40 billion annually by 2075. CSHub Director Randolph Kirchain explains why the #Trump admin. & new #Congress must invest in stronger #construction to save lives, homes, and long-term spending. realclearenergy.org/articles/2025/…

Don't miss us at @NASEMTRB's 2025 Annual Meeting! @ConcreteAdvFdn @PCA_Daily @PaveConcrete @MIT @MIT_CEE See our presentation list: linkedin.com/feed/update/ur…

#Cement used in U.S. single-family homes can sequester enough carbon to account for ~40% of process emissions from the production of cement used to build them. Learn about our probabilistic #carbonuptake accounting framework in our recent webinar youtube.com/watch?v=DKJn1m…

Join Prof. Elsa Olivetti 10/24 11am ET as she discusses how #languagemodels can help acquire data and develop models for beneficial use of #byproducts specific to the #builtenvironment. @OlivettiGroup @MITEngineering mit.zoom.us/webinar/regist…

#Carbon capture, utilization & storage (CCUS) will play a key role in the decarbonization of the #cement industry. This @CSHub_MIT report explores how the industry can enable widespread industrial CCUS adoption. hubs.li/Q02MlwH60

Concrete sustainability took to @WhiteHouse recently as leaders met for the #Concrete Innovation Summit. @hessam_aj participated in the summit, which discussed bolstering concrete as part of the #sustainability solution. @ConcreteAdvFdn @PCA_Daily whitehouse.gov/ostp/news-upda…

Our new brief outlines an element-based approach to model the #carbonuptake of single-family homes. Authored by @hessam_aj and Randolph Kirchain. @MIT @ConcreteAdvFdn #sustainability #ccus #concrete #cement Read the brief: cshub.mit.edu/wp-content/upl…

🌞 Summer weather is here to stay! In a recent episode of “Created Equal” by @wdet, sustainability expert @hessam_aj and local forester Lawrence Sobson discussed the increased risk of heat waves in urban areas like Detroit. (bit.ly/3XBNhYW) PC: @CityofDetroit

.@hessam_aj joined @wdet's #CreatedEqual podcast to discuss the #UrbanHeatIsland effect and how strategies like #reflectivepavements can mitigate #extremeheat. @SHDetroit @MichiganDNR open.spotify.com/episode/0FMYtd…

Urban areas tend to suffer the most from heat waves like this week’s. Sustainability expert Hessam AzariJafari and local forester Lawrence Sobson joined @SHDetroit on Created Equal to discuss innovative ways for Detroit to build up climate resilience 🏖 buff.ly/3VBoKQW

The heat this week feels inescapable. But its worse in cities thanks to something called the 'Urban Heat Islands' effect. Hessam AzariJafari from @CSHub_MIT and Lawrence Sobson from @MichiganDNR join @SHDetroit for #CreatedEqual. #HeatIslands #TreeEquity
