Is the use of limestone products in building materials or for environmental applications considered a LEED raw material?
Where do you find such information as to LEED credits and what does this do for a company that manufactures fine limestone products for building materials and environmental applications like scrubbing SO2 gases from power plants?
Can a company or Regional Materials MRc5 certification be given to a company and production faciltiies or is LEED a one project at a time program that has to be tracked on each project with materials used?

Thank you
