The first thing I did when I read the title was "control+F: fire".

More importantly, the wooden beams created with modern processes are so big and solid that it actually takes enormously high temperatures to set them on fire — below those temperatures, the surface of the beam simply chars, while the beam itself maintains its structural integrity. "Steel is actually less fire resistant in its pure form," Snapp said. "When steel hits a certain temperature it starts melting, the connections break."

Nice.... nice... yes, now that I use my brain for 2 seconds this makes sense...

The substantially low amount of concrete used impressed me greatly too, (concrete is created by turning CaO3 into CaO (I BELIEVE but I just learned that yesterday, so, it's still finding it's place in my brain-harddrive), producing CO2 as a by product (this I am sure of), it is one of the most directly harmful processes we use),

Obviously, there are aspects of construction that will emit CO2 no matter what material you use. But steel and concrete also have carbon emissions intrinsic to that material: Sixty percent of concrete's emissions, for instance, come from the chemical reaction to make the concrete. Replacing a lot of steel and concrete construction with wood could save us a lot of CO2 output.
