Decarbonize
every flight.
The carbon ledger, decarbonization optimizer and compliance OS for airlines. Measure with certified methods, cut with the right levers, and prove it to every regulator.
IATA RP1726 · UK DEFRA 2025 · ICAO CORSIA · ReFuelEU · EU ETS
From raw flight data to a signed compliance file.
One continuous workflow — the same four steps your sustainability, operations and finance teams already think in.
Calculate
Build a per-flight carbon ledger from real fuel burn — LTO + cruise, SAF blend, and non-CO₂ radiative forcing — using IATA RP1726 and UK DEFRA 2025 factors.
Reduce
Model SAF, operational and fleet levers on a marginal-abatement cost curve. See exactly what each tonne of abatement costs before you commit.
Offset
Buy down the residual with CORSIA-eligible units and renewable energy certificates, tracked from purchase to retirement.
Comply
Generate audit packages with reasoning trees and file to every authority — backed by an immutable, signed audit chain.
Scope 1, 2 and 3 transparent to the gram.
How we calculateScope 1 — Direct
Jet-fuel combustion across the flight cycle. Fuel burn from aircraft + engine data, airspace-aware attribution, SAF-blend reductions, and non-CO₂ effects (contrails, NOₓ) with radiative forcing.
Scope 2 — Energy
Purchased electricity and ground energy at hubs and stations, net of renewable energy certificates — so reported emissions match what you actually procure.
Scope 3 — Value chain
Well-to-tank fuel production, ground operations (APU/GPU/GSE) and upstream supply — the indirect footprint regulators increasingly expect you to report.
Everything an airline needs, in one cockpit.
Carbon Ledger
An editable, audit-grade spreadsheet of every flight's footprint with multiple calculation methods side by side.
Decarb Optimizer
MACC curves and scenario modelling across SAF, operations, fleet and contrail-avoidance levers.
Carbon Offsetting
CORSIA + REC retirement tracking with full coverage and waterfall visualisations.
Compliance & Audits
On-demand audits that test your data against regulatory controls and explain every finding.
