The calculated carbon footprints were 0.8 kgCO2,eq./kg for N and 1.8 kgCO2,eq./kg for P, whereas the carbon footprints for mineral fertilizers were 1.9–7.8 kgCO2,eq./kg for N and 2.3–4.5 kgCO2,eq./kg for P. The reduction of GhG emission in organic fertilizer production in comparison with the emission in mineral fertilizer production was on average 78% for N and 41% for P. On the other hand, inclusion of N2O and Ch4 emissions from composting increases the carbon footprints of nitrogen and phosphorus but there is high uncertainty included with these emissions. The value of nutrients in the biofertilizers is also uncertain but the interest towards using of them is increasing in Finland.
