Natural thermal insulation materials in life cycle analysis on the example of hemp wool: balancing CO2 sequestration and emissions in the context of sustainable construction (2025)

The study aimed to assess the climate impact of hemp-fibre-based thermal insulation materials, focusing on CO2 sequestration and end-of-life scenarios. Four hemp mats were analysed using Environmental Product Declarations (EPD). The most favourable GWP balance (4.53 kg CO2e/m3) was recorded for the
