Climate Impact
Cut Lifecycle Carbon Intensity at Source
Metafuels AI control improves hydrogen use and product carbon efficiency. This produces a lower LCA footprint per tonne of SAF, with evidence sustainability teams can apply to offtake talks and CORSIA filings.
LCA Footprint
How Metafuels Changes LCA Results
Lifecycle carbon intensity for MtJ e-SAF (gCO2e/MJ) is shown by process stage. Metafuels cuts emissions during green hydrogen use (Stages 3-4) and reprocessing of off-spec fuel (Stage 6). Stages 1 and 2, feedstock and CO2 capture, precede platform coverage.
Regulatory Fit
Aligned With Key SAF Frameworks
Metafuels checks process compliance live against key SAF sustainability frameworks. An audit trail is created automatically for every production batch.
EU Aviation
ReFuelEU Aviation Regulation 2023/2405
SAF blending requirements for 2025-2050, including e-fuel sub-quotas from 2030
Metafuels compares each batch's CI with the regulation's default emission values. Operators can export machine-readable reports prepared for submission through the EASA SAF Registry workflow.
ICAO
CORSIA Eligible Fuels Criteria
International aviation carbon reduction scheme, with lifecycle rules under ICAO SARPs Annex 16 Vol. IV
Every production run receives a CI value linked to sensor-timestamped batches. Digital chain-of-custody reports match auditor needs at SCS Global, Control Union, and Bureau Veritas.
Fuel Quality
ASTM D7566 Annex A7 (MTJ-SPK)
ASTM International specification for methanol-to-jet synthetic paraffinic kerosene blending
Compliance Monitor checks flash point, freeze point, viscosity, and aromatic content against D7566 A7 limits in real time. Fractionation alerts arrive 40-60 minutes before custody-transfer blend testing.
UK SAF
UK Sustainable Aviation Fuel Mandate
10% SAF by 2030, 22% by 2040, with a 40% savings threshold versus fossil kerosene
Metafuels calculates emissions using the UK DfT-approved LCA method. It supports biomethanol and e-methanol pathways included on the mandate's approved feedstock list.
Drop-In Fuel Use
Existing Airport Infrastructure Works
Under ASTM D7566 Annex A7, MTJ-SPK is approved for blending with conventional Jet A-1 at up to 50% by volume. The mixture performs like fossil kerosene through current airport fueling networks, aircraft fuel equipment, and engines, with no alterations.
This fuel needs no dedicated handling. Airlines operating Airbus A320 family aircraft, Boeing 737 MAX, or wide-body fleets can uplift MTJ-SAF at any airport supplied by an approved blending facility. Metafuels-optimized plants remain within the specification envelope defined by ASTM A7, so their product joins the existing supply chain without special dispensation.
For aviation net-zero targets, the operational implication is clear: a 50% blend lowers lifecycle CO2 intensity per flight by 35-47%, based on the feedstock pathway, while current operations, maintenance intervals, and safety procedures remain unchanged. The sustainability gain comes from the fuel, rather than a certification workaround.
