...carbon emissions it was the other way round - operational carbon was starting to be seen as important, but no-one was talking about the capital (‘embodied’) carbon of construction. In 2007 I moved into academia where I have now researched and written about embodied carbon of buildings - only one part of what we need to think about for our built environment, as we face...

...or carbon and nitrogen together, in a medium of gas, solid or liquid, are diffused into the surface of component(s), particularly those made from low carbon steels. Changes to the chemical composition of the surface (austenite) lead to high carbon content in the surface material, which when quenched transforms to a hard coating (martensite)...[Images to demonstrate...
