This report gives a short overview about the life cycle assessment of conventional and . porous asphalt and interlocking modular paving stones together with subbase structures of aggregate, pipes .. Crushed stone carbon footprint value is used in case of concrete paving block structure for load bearing.
The Natural Stone Council (NSC) has commissioned some life-cycle inventory data for use in life cycle assessments. Almost 90% of the effort in doing a life cycle assessment involves getting reliable data. For example, the NSC has data that the Global Warming Potential for granite quarrying is 100 kg of carbon dioxide.
