Ask 100 designers for their opinion on marble, and they will almost all agree that itâs a great material to jazz up an interior. It can add a dose of drama to a simple kitchen or transform an apartment bathroom into one straight out of an Italian palazzo. But when it comes to marbleâs environmental footprint, opinions are divided. Some will say that marble is the very definition of a sustainable building material. It comes, after all, straight from the earth and can be extracted from quarries all around the globe. âItâs the original green material,â says Boston-based designer Liz Caan, who uses marble as often as her clients will let her. âIt doesnât require other resources to create, and there is an abundant supply.â
