3. The GHG emissions reduction stated here, relates to the comparison of the calculated carbon footprint of product (CFP) for the renewable components in the PMSC race fuel versus a 94 grams CO2e/MJ of EU Renewable Energy Directive II baseline comparator. Emissions reduction of up to 85% from renewable components vs. conventional are based on carbon footprint of product calculations conducted under ISO 14067 methodology, effectively referenced as a well-to-wheels boundary, taking into account the feedstock, production, transportation, and combustion related emissions to manufacture the blend of renewable components mentioned here. A functional unit of 1 MJ of fuels was used for the comparison.
4. Benefit is up to 34 percent compared with conventional petroleum-based HFO/VLSFO, calculated on an energy basis. Well-to-wake GHG emissions reduction calculated using the equation as published in the Directive 2009/30/EC of the European Parliament and of the Council Annex IV A and EN 16258.
