Norwegian firm Snøhetta has partnered with Norwegian startup Saferock to pilot and market a more sustainable concrete using the latter’s patented geopolymer concrete technology. Production of cement, the binder of conventional concrete, is responsible for 8% of the world’s carbon emissions; meanwhile, the carbon footprint of producing geopolymers is 70% less than that of traditional cement. Snøhetta and Saferock aim to produce a fully carbon-neutral concrete, piloting and scaling up production of the sustainable material over the next four years.

“The next step will be to ensure that the technology and materials are a part of a circular ecosystem,” according to Snøhetta’s press release announcing the project. “This will truly impact the industry’s environmental footprint.” [Snøhetta]

May 31 marked the 100th anniversary of the Tulsa Race Massacre, during which a white mob attacked the Greenwood neighborhood of Tulsa, Okla., decimating a thriving Black community and murdering hundreds of Black residents. The New York Times recreates Greenwood’s lost residents, homes, and prosperity through an interactive 3D model, introducing readers to experience the community before its violent destruction. Although many details of the event were “willingly buried in history,” NYT reporters used census data, city directories, newspaper articles, and survivor testimonies to build a detailed account of Greenwood before its destruction, highlighting the “people who made up the neighborhood and contributed to its vibrancy.” [The New York Times]
