Technology not growing fast enough to decarbonize steel and cement industries by 2050, says study
Steel and cement are two materials that no society can do without. Their production comes with a significant carbon footprint, however. To meet zero-emission targets under the Paris Agreement, countries, cities, and industries are depending on new large-scale infrastructure for CO2 transport and sto...
The problem isnt technology, its insatiable growth requiring infinite construction projects. The system is the issue, the technology is a symptom
That's part of it, but it's also necessary that whatever construction continues to happen not add CO2 to the atmosphere.
Fortunately there was an advance in this field in just the past year:

The problem with concrete has long been that you can make carbon-removing-concrete, but architects won't specify it and contractors won't use it. Making it happen at scale isn't just a technical problem around material manufacturing, but a social one around getting people to trust the new material and use it.
