The product is the result of a six-year collaboration between LaFargeHolcim and Solidia and uses a special binder — produced at lower temperatures — and patented curing process that uses CO2 rather than water. By adding and absorbing CO2, Solidia Concrete reaches strength in less than 24 hours unlike precast concrete made with Portland cement, which takes 28 days to reach strength. — Construction Dive
Construction Dive takes a look at a new business venture launched by LafargeHolcim and Solidia Technologies that will bring carbon-sequestering precast concrete production capabilities to the United States. The new Solidia Concrete product, according to the companies, cures in less than... View full entry

Compressed air energy storage has been used for decades, but only at two facilities in Germany and Alabama, built before solar and wind started creating challenges for power grid operators.
“This is a pretty simple concept,” said Bobby Bailie, director of business development for energy storage at the German industrial firm Siemens. “You’re pushing air into a cavern, storing that energy. And at times when you need it, you pull it back out.”
— The Los Angeles Times
Can a giant underground salt cave in the Utah desert hold a potential answer to Los Angeles’s growing sustainable energy needs? The Los Angeles Times digs into a new-old approach for storing energy in compressed air deposits deep underground. The compressed air, generated with the help of... View full entry
The head of the Vatican’s extensive gardens has announced an initiative, already underway, to totally eliminate the use of chemical pesticides and fertilizers. — Aleteia

Proposition 105, a measure backed by a group called Building a Better Phoenix, would halt all future light rail expansions, directing already-earmarked tax dollars toward “other transportation improvements”—mostly road construction. Like a number of efforts to kill urban-rail plans around the U.S., the initiative to stop Phoenix’s transit development has ties to Americans for Prosperity, the advocacy group funded by David H. Koch and Charles Koch. — CityLab
CityLab's Laura Bliss delves into the multi-faceted and contentious back-and-forth effort to build new light rail infrastructure in Phoenix, Arizona, where issues of urban equity, dark political money, and changing transportation needs have rankled residents of all stripes. View full entry
The Autorité Environnementale (AE) has issued a statement saying a future scenarios study by the airport had underestimated the project’s environmental impact and overestimated its economic benefits. The new Terminal 1 extension is scheduled to open at the start of 2023 [...] However, it appears those plans clash with France’s new target to be carbon neutral by 2050, prompting the environmental agency to demand clarification. — Architects Journal UK
In 2017, Foster + Partners' competition submission beat a proposal by Rogers Stirk Harbour + Partners for the opportunity to design the new extension to Marseille Provence Airport in France. More recently, France's environmental agency has raised questions concerning the project... View full entry

More than 11 billion tons of ice was lost to the oceans by surface melt on Wednesday alone, creating a net mass ice loss of some 217 billion tons from Greenland in July.
The scope of Wednesday’s ice melt is a number difficult to grasp. To understand just how much ice is being lost, a mere 1 billion tons—or 1 gigaton—of ice loss is equivalent to about 400,000 Olympic-sized swimming pools, the Danish Meteorological Institute said.
— The Associated Press
The Associated Press reports that a summer heatwave that recently scorched Europe has moved north to Greenland, where the elevated temperatures have produced record glacial melt. While 82-percent of Greenland is covered in ice, nearly 60-percent of the island's total ice sheet is showing... View full entry
New Jersey's largest and oldest power company is pledging to deliver carbon-free electricity to fight climate change. To get there, the power company is shutting down its coal plants, betting big on offshore wind and working hard to keep its existing nuclear plant alive. PSEG said it won't build or acquire any new fossil-fueled power plants, including those running on dirt-cheap natural gas. — CNN Business
Announced in July, one of the oldest power companies in the U.S. is taking the next step towards addressing their involvement in battling climate change. The New Jersey power company PSEG has used fossil fuels to power their plants for the last 116 years. As the oldest power company in America... View full entry
“If you’re building a greenhouse in a climate emergency, it’s a pretty odd thing to do to say the least,” said Simon Sturgis, an adviser to the government and the Greater London Authority, as well as chairman of the Royal Institute of British Architects sustainability group. “If you’re using standard glass facades you need a lot of energy to cool them down, and using a lot of energy equates to a lot of carbon emissions.” — The Guardian
As the global community continues to mobilize against the rising threat of climate collapse, cities and other entities are moving toward banning or limiting the future development of all-glass skyscrapers due to the buildings' high energy demands, according to a report in The... View full entry
For everyone working in the construction industry, meeting the needs of our society without breaching the earth’s ecological boundaries will demand a paradigm shift in our behaviour.
