The main objective of this study was to analyse the climate change impact of biochar production and application across the entire Swiss agricultural value chain quantified by the 100-year time horizon global warming potential (GWP100), hereinafter referred to as GWP for simplicity, using life cycle assessment (LCA). In Switzerland, biochar is often not applied directly to the soil; instead, it is used in animal husbandry (feed additive, animal bedding),
so that it enters the soil as part of the manure. Given the potential effects of biochar at various levels beyond its application (e.g. in animals, on the air quality in the stable, in the manure, etc.), this is also referred to as cascade use.
