Life cycle greenhouse gas emissions of hemp-lime wall constructions in the UK

► Hemp-lime walls are considered to have low environmental impact. ► A functional unit (FU) of timber frame wall 1 m2 × 300 mm thick has been developed. ► Life cycle process and associated greenhouse gas were established. ► Base on PAS2050 the FU could sequestrate 82.7 kg of CO2e over its life cycle. ► Potential net absorption of 36.08 kg CO2e greenhouse gases from atmosphere.
