(Part of the No Sweat Solutions series.)
What follows is a table with a (very) incomplete list of means of reducing material intensity in building. These means alone could reduce the impact of constructing buildings by about 75 percent or more, and thus greenhouse-gas emissions from construction and destruction of buildings by about half.
Since we have green builders on this site, I invite additions to the list, especially if you can cite sources for impact reduction. I also invite comments on whether any of these are not as green as they appear at first blush.
Note that operations account for a great deal more of the impact of building than construction. So these are green only to the extent they do not compromise operating efficiency.
Table below the fold.
