MESSAGE scenarios

Added

• Added MESSAGE scenarios.
• Region-to-feedstock mapping files for biofuels:
  • premise/iam_variables_mapping/iam_region_to_biodiesel_feedstock.yaml
  • premise/iam_variables_mapping/iam_region_to_bioethanol_feedstock.yaml
• Metals post-allocation correction files for newer ecoinvent versions:
  • premise/data/metals/post-allocation_correction/corrections_311.yaml
  • premise/data/metals/post-allocation_correction/corrections_312.yaml

Changed

• Expanded fuel regionalization, including higher-level fuel activities.
• Expanded biomass supply-chain regionalization.
• Updated IAM variable mappings across sectors (final energy, fuels, heat, transport, electricity, steel, CDR).
• Updated GCAM topology and related mapping assets.
• Updated Brightway export/import integration (premise/brightway2.py, premise/brightway25.py).
• Updated inventory assets:
  • premise/data/additional_inventories/lci-biofuels.xlsx
  • premise/data/additional_inventories/lci-final-energy.xlsx
  • premise/data/additional_inventories/lci-pass_cars.xlsx
• Updated SimaPro category and import classification mappings.

Fixed

• Multiple MESSAGE mapping fixes (fuels, final energy, industrial heat).
• Duplicate regionalization / duplicate dataset creation issue.
• Improved missing-file error messages.
• Unit normalization for IAM inputs provided in PJ/yr (conversion to EJ/yr).
• Updated NOx and PM2.5 emission factors for diesel passenger cars.
• Reintroduced SSP2-Base as an accepted scenario.

Data cleanup

• Removed obsolete fuel config files:
  • premise/data/fuels/fuel_efficiency_parameters.yml
  • premise/data/fuels/fuel_markets.yml
  • premise/data/fuels/hydrogen_supply_losses.yml
  • premise/data/fuels/supply_chain_scenarios.yml
• Renamed metals correction file:
  • premise/data/metals/post-allocation_correction/corrections.yaml
  • to premise/data/metals/post-allocation_correction/corrections_310.yaml

Documentation

• Updated README.md, multiple docs pages, and example notebooks.
