Carbon Fibre LCA and Environmental Hotspot Identification
topic
Carbon fibre production LCA shows global warming potential of 20 to 30 kilograms CO2 equivalent per kilogram dominated by PAN precursor production at 40 percent and energy-intensive carbonisation furnace operation at 45 percent of total impact, with water footprint of 150 to 400 litres per kilogram and toxic emission potential from carbonisation off-gases requiring thermal oxidiser treatment before atmospheric discharge.
Role
Quantifies the significant environmental cost of carbon fibre production that must be offset by lightweight composite structural performance benefits over the full vehicle or aircraft service life, providing the carbon payback period analysis needed to determine whether carbon fibre lightweight structures deliver genuine lifecycle carbon reduction versus their higher-impact aluminium or steel alternatives.
