Swedish proposal for a sustainable aviation fuel mandate in Sweden
A report detailing the outcomes of an investigation commissioned by the Swedish government on the use of biojet fuel in Sweden was made public in March 2019.
The report, which is in Swedish, includes a summary section in English, which can be downloaded here. Below outlines some highlights of this proposed greenhouse gas emissions (GHG) reduction obligation for jet fuel in Sweden.
- The biofuels for the proposed mandate are potentially to be derived from the forest and paper industry residues.
- The proposed biofuel blend ratios into conventional jet fuel are defined for each year from 2021 to 2030 (see Table 1 in the summary).
- These blend ratios increase from 1% by volume in 2021 to 30% in 2030.
- These ratios correspond to biojet volumes of 13,500 and 424,000 m3, respectively, in Sweden (see Table 2).
- And they also correspond to GHG reductions of 0.8% in 2021 and 27% in 2030 (assuming an average biofuel footprint of 16 and 8.9 gCO2e/MJ for 2021 and 2030, respectively, considering improvements in production).
- This is expected to increase the ticket prices by 3 and 250 SEK (0.30 and 24 euros) for a domestic flight in 2021 and for an extra-European flight in 2030, respectively (see Table 3).
- These reduction values are essentially due to two factors (see Figures 1 and 2): 1. Biogenic combustion of the blended fuel (e.g. 24% in 2030). 2. Reduced demand due to increased ticket prices (e.g. 3% in 2030).
- The study yet also assumes an increase of ca. 27% in passenger volume by 2030 compared to 2017 (see Figure 3).
- This translates into an increase in total emissions (biogenic and otherwise) and decreased non-biogenic emissions by 2030 (see Figure 1).
- The proposal also sets a goal of 100% biojet use in Sweden by 2045.
- The life cycle analysis of the investigation takes into account not only the production emissions and CO2 combustion emissions but also the non-CO2 combustion effects. The latter though is kept constant even with varied blend ratios.
