Hemp fibres are very suitable replacements for a variety of fossil-based materials. In the study, 19 fossil-based applications are compared to their hemp-based alternatives regarding the environmental impacts on climate change and primary energy use. The products are compared based on their functionality and based on a unit of area. Both approaches are crucial for the comparison and improvement of products. Not only the use of fossil fuels but also the use of land will become a limiting factor in the future. The use of hemp fibres requires land for the cultivation of hemp. However land is not limitlessly available, instead demand for it is growing and land use efficiency will be an increasingly important factor as competition rises for food, feed, energy, materials, urban areas and protected natural zones.
