Purpose There is growing interest in using crop residues, particularly cereal straw, to replace fossil fuels in heat and electricity production. The purpose of the present study was to assess and compare the environmental impacts of straw production in two European Union countries, Poland and Finland. Design/methodology/approach The selected environmental impacts were greenhouse gas (GHG) emissions, biodiversity and soil physical quality. The latter was represented by the indicators of soil erosion and compaction. For biodiversity and erosion assessment, the authors used two methods that could be used with existing easily accessible data and thus did not require excessive fieldwork. Findings Compared to the fossil reference fuel, coal, straw production caused minimal GHG emissions in both of the subject countries. Biodiversity and erosion impacts were greater in Poland, while the potential risk of soil compaction caused by field traffic is greater in Finland. Originality/value The study provides insight into the impacts of bioenergy production on biodiversity and soil quality, of which there is currently limited knowledge.
