8.1 · Per-commodity substitution

Indicative substitution at Programme Year 10.

All figures are indicative; assumes the Programme's three pillars deployed at the indicative scales described in Section 7. Substitution is calculated as a percentage of the recent (2023) import baseline for each commodity; effective substitution rises with sustained operation.

CommoditySource pillarYear-10 substitution rangeNotes
Nitrogen fertilizer (urea-equivalent)I5–15 %Direct biofertilizer + digestate; closes part of the urea import gap
Liquefied petroleum gas (LPG)I3–10 %CBM substitution in cooking, transport, industrial-heat applications
Animal-feed proteinI2–6 %Azolla-based feed supplement (17–25 % crude protein)
Methanol & light-chemical feedstockI~ 100 % opportunityThe country has no commercial methanol production at scale; full domestic methanol becomes feasible
Crude oil (refinery feedstock)II (HTL biocrude)1–3 %Co-processing in existing complex refinery; low-CAPEX intermediate route
Diesel (road, marine, industrial)II + III1–3 %FT diesel co-product + HTL diesel cut + ATJ diesel co-product
Gasoline (motor)II + III1–3 %FT naphtha + ATJ light fraction + closing of E10 mandate gap
Jet fuel (aviation)I + II + III2–6 % (early); 6–15 % (full deployment)ATJ-SPK + FT-SPK + (when qualified) MTJ-SPK; aligned with credible early-mandate SAF blending requirements
Imported solid fuels for cogenerationII + IIIavoided incremental importBagasse cogen + falcata residue cogen; reduces additional coal-import demand

The single largest substitution — in absolute fiscal terms — is the methanol opportunity. The Republic does not currently produce methanol at commercial scale and imports its requirement. A domestic methanol capability anchored on Pillar I CBM, with the option to feed marine fuel (in line with the IMO's MARPOL Annex VI tightening) and chemical-industry markets in addition to the contingent MTJ-SPK route, is structurally significant on its own merits.

8.2 · Carbon intensity by pillar

Indicative lifecycle CO2-equivalent intensity (per MJ fuel).

Lifecycle carbon intensity (CI) is the metric used in ICAO CORSIA, EU ReFuelEU, UK SAF Mandate, and US 45Z eligibility frameworks. Indicative ranges, expressed as gCO2e per MJ of finished fuel:

PathwayIndicative CI (gCO2e/MJ)Reference baseline
Conventional Jet A-1 (fossil)~ 89CORSIA reference baseline
Conventional gasoline (fossil)~ 94Standard reference
Conventional diesel (fossil)~ 90Standard reference
ATJ-SPK from sugarcane ethanol (Pillar III)~ 25–45Subject to detailed lifecycle assessment; bagasse cogen offset; tropical sugarcane reference
FT-SPK from biomass gasification (Pillar II Route A)~ 10–30Subject to LCA; higher when biomass supply is from sustainably managed plantations
HTL biocrude upgraded via refinery co-processing (Pillar II Route B)~ 30–55Range reflects co-processing fraction; co-processing rules vary by jurisdiction
MTJ-SPK from azolla-derived methanol (Pillar I, contingent)~ 15–40Subject to LCA; depends heavily on AD efficiency and digestate utilization
CBM (compressed biomethane) for LPG substitution~ 5–25Lower bound when methane leakage is well-controlled; methane abatement co-benefit material

All CI ranges are illustrative and subject to formal lifecycle assessment in the Programme's feasibility-study phase, conducted to ICAO CORSIA / ISO 14040-44 methodologies, with explicit treatment of indirect land-use change (ILUC).

8.3 · Non-CO2 aviation effects

Why low-aromatic, paraffinic SAF matters beyond carbon.

Aviation's climate impact is approximately equally split between CO2 and a basket of non-CO2 effects — principally contrail formation, water-vapour effects, and aerosol-cloud interactions — though the exact ratio remains an active area of scientific work. Contrail formation, in particular, is driven by the soot and particulate-precursor content of conventional jet fuel, which is in turn driven by aromatic hydrocarbon content.

All three of the Programme's SAF pathways — ATJ-SPK, FT-SPK, MTJ-SPK — produce synthetic paraffinic kerosene, which is essentially aromatic-free by chemistry. This translates directly into substantially lower soot mass, lower particle-number emissions, and consequently materially reduced contrail-formation potential. The chemistry is the same chemistry that underpins the DM-XTech Group's tLCAF product line, which has been independently validated by the Translational Energy Research Centre at the University of Sheffield, with reported reductions of approximately 98 % in soot mass and 95 % in particle number relative to baseline Jet A-1.

EU Regulation 2024/2493 alignment. The European Union's regulation on non-CO2 aviation reporting and reduction (in force from 2025) creates structural commercial demand for fuels with low aromatic content and demonstrable particulate-and-contrail reductions. The Programme's SAF outputs — produced from indigenous biological feedstocks — are structurally aligned with this regulatory pressure for export-grade SAF deliveries to UK and EU airline customers.
8.4 · Co-benefits

What else the Programme delivers, beyond fuel and fertilizer.

Rural employment

Distributed-cluster job creation

Each pillar generates direct rural employment through cultivation, harvesting, aggregation, processing, transport, and operations. Indicative direct + indirect employment at full deployment: tens of thousands of FTE-year positions, geographically distributed across Mindanao, the Visayas, and Luzon.

Foreign-exchange retention

Reduced petroleum & fertilizer imports

At indicative full-deployment substitution levels, the Programme retains a meaningful share of the country's combined petroleum and fertilizer import bill in domestic value-added. This translates into improved current-account position, reduced FX volatility exposure, and lower fiscal pressure during external shocks.

Restored degraded land

~ 100,000s of hectares

Programme cultivation deliberately targets degraded grasslands (cogon), abandoned farmland, and post-mining areas. The cumulative Programme footprint is structurally a land-restoration programme as well as a fuels programme.

Methane abatement

Captured biogenic CH4

Anaerobic digestion of organic waste streams (vinasse, agricultural residues, manures) captures methane that would otherwise be released, generating direct climate co-benefit measurable under CORSIA and the country's NDC framework.

Soil carbon

Biochar return + digestate

Pillar II HTL biochar and the recycled digestate stream from Pillars I and III together build a sustained soil-carbon-storage layer in agricultural soils — an additional, monitorable carbon-credit revenue stream alongside the direct fuel-substitution attributes.

Energy resilience

Distributed cogeneration

Mill-cluster cogeneration (Pillar III bagasse) and biomass-fired cogeneration at regional hubs (Pillar II) provide distributed grid-export capacity in regions historically exposed to electricity-supply disruptions during typhoons and grid stress events.
