Industrial Emissions Attribution

Pinpointing which industrial facilities — steel mills, refineries, cement plants, petrochemical complexes — are responsible for specific greenhouse gas plumes, using satellite-derived spectroscopy and thermal imaging.

Governments signing up to net-zero commitments face an immediate credibility problem: self-reported facility emissions from heavy industry are systematically under-declared, sometimes by 40–70% relative to independent atmospheric measurements. Without an independent space-based check, regulators are negotiating carbon budgets and handing out allowances on the basis of figures that emitters themselves supply. The gap between reported and actual emissions is not an accounting rounding error — it is a structural policy failure that invalidates any downstream carbon market or border carbon adjustment.

A sovereign constellation couples shortwave-infrared (SWIR) spectrometers tuned to CO₂ and CH₄ absorption bands with thermal infrared (TIR) sensors that identify furnace and flare heat signatures, and optional synthetic aperture radar to confirm plant operational status. Data fused at ground level allows analysts to isolate individual stacks and attribute measured column concentrations to specific assets using Gaussian plume inversion and Lagrangian transport modelling. At ~30m spatial resolution and daily revisit, this stack moves emissions attribution from a statistical estimate to a facility-level fact.

The operational outcome is leverage: a regulator armed with satellite-derived attribution can challenge a steel mill's annual emissions declaration before the compliance window closes, not three years later in a court dispute. That leverage feeds directly into carbon pricing, trade-exposed sector policy and bilateral enforcement of carbon border adjustment mechanisms like the EU CBAM. Nations that depend on a commercial provider or a foreign government programme for these numbers are, in effect, outsourcing the integrity of their own industrial policy.

What matters

Facility-level CH₄ and CO₂ attribution requires column-averaged dry-air mole fraction (XCO₂, XCH₄) at ≤1 ppm precision — a threshold commercial SWIR imagers now routinely exceed.
The EU Carbon Border Adjustment Mechanism (CBAM) creates direct financial consequences for nations that cannot independently verify the embedded emissions of exported steel, cement and aluminium.
Gaussian plume inversion accuracy degrades sharply when wind-field data is coarse; coupling satellite data with sovereign NWP output is operationally necessary, not optional.
Export controls on the most capable hyperspectral sensors (US EAR, EU dual-use lists) mean a nation relying on foreign supply chains can be cut off precisely when a diplomatic or trade dispute makes the data most valuable.

Sovereignty score: 8/10 — A nation that cannot independently attribute industrial emissions to specific facilities cannot enforce its own carbon laws, defend its trade position under CBAM, or negotiate from evidence in international climate diplomacy.

Carbon border adjustment enforcement depends on credible third-party emissions data; relying on a foreign commercial provider hands that credibility — and potential trade leverage — to another jurisdiction.
Domestic carbon pricing schemes collapse in political legitimacy if large emitters can successfully dispute the measurement record, which is far easier when the data originates outside the regulating country's legal reach.
Export controls on high-sensitivity SWIR spectrometers and hyperspectral sensors mean supply of the critical payload can be restricted by a foreign government at precisely the moment diplomatic tensions make accurate attribution most consequential.
National inventory submissions to the UNFCCC require reproducible, auditable measurement chains; a sovereign pipeline provides the unbroken chain of custody that a licensed commercial data product contractually cannot guarantee.

Reference architecture
