A provocative new study argues that a building’s real environmental cost is measured by how well it survives disaster, not by how little it weighs.

Building standards treat all concrete the same, hindering the use of greener concrete, but climate conditions play a much bigger role in determining a structure’s durability

Urban planners have been asking the wrong question. It’s not how dense a city is—it’s how close. The sweet spot for shorter commutes and lower emissions, for many cities, forms a ring.
