Alternative Fuels (ANAC)

Software tool for sustainability analysis of alternative jet fuel from sugarcane and other feedstock

Alternative fuels with a lower lifecycle CO2 footprint than conventional fuels are one of the means by which CO2 emissions from aviation can be reduced. With support from the Inter-American Development Bank (IDB), Brazil’s National Civil Aviation Agency (ANAC) requested Metron Aviation’s assistance to develop a software model to compute the greenhouse (GHG) emissions related to flights using renewable fuels including those that have sugar-cane as feedstock, an abundant raw material in Brazil.

The calculation tool gives information about the carbon savings on a lifecycle analysis (LCA) basis and other potential environmental benefits associated with introduction of renewable fuels compared to the use of fossil fuels. The main objective of this work was to help ANAC and other decision-makers produce GHG inventories that capture the emissions reductions expected by the adoption of renewable fuels. A long term objective of this work was to help foster the development and adoption of alternative fuels by providing information regarding their environmental benefits that can be used to support the business case for their adoption. The software module was integrated into ANAC’s existing Mapeamento de Impacto Ambiental de Transporte Aéreo (MIATA) tool. With the new module, MIATA is now capable of estimating the potential lifecycle CO2 emissions reductions from using renewable fuels.

This Fuel Reporting module has:

  • The functionality to allow the analyst to control the penetration rate of renewable fuels and the level of lifecycle CO2 reductions compared to a conventional jet fuel baseline.
  • Allows the user to display information for individual flights and aggregate data by geographic.
