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.
  
  Yeah, social attitudes are harder to change than material science for sure. Still have to just tackle it one step at a time though.
