90% export capacity offline
Kharg Island handles 90% of Iranian oil exports. Pumping infrastructure and loading arms have been struck. Tankers in the area have diverted. Terminal is not actively burning but is non-operational.

The 1991 comparison
Iraq's 1991 oil well fires burned for 10 months and released approximately 2.1 billion tonnes of CO₂ equivalent — more than the entire UK emits in five years. The black rain event contaminated soil across Kuwait and parts of Saudi Arabia with polycyclic aromatic hydrocarbons (PAHs) that are still detectable today.
The Iranian oil infrastructure fires are smaller in scale, but the South Pars methane release adds a dimension absent from 1991. Methane's short-term warming potential is 86× CO₂, meaning even a fraction of South Pars output burning uncontrolled represents an outsized climate event.

Persian Gulf coral reefs are already the world's most heat-stressed. Oil contamination adds acute toxicity stress to systems already operating at thermal limits. Recovery timescale is measured in decades.

Qatar, Bahrain, and UAE desalination plants drawing from contaminated waters face potential shutdown. Qatar gets 99% of its freshwater from desalination. A prolonged spill event represents a regional drinking water crisis.

Black Carbon Soil Settling
PAH and black carbon deposits from refinery fires will settle into topsoil across Khuzestan. Elevated cancer risk for agricultural workers persists for a decade minimum.

Groundwater Heavy Metals
Lead, tungsten, and mercury from munitions leach into the water table slowly. Khuzestan aquifers serving 6M people will carry elevated contamination for a generation.

Coral Reef Recovery
Persian Gulf coral reefs already operating at thermal limits. Oil contamination combined with continued ocean warming means some reefs may not recover within the century.

Complete soil remediation and return of full agricultural productivity across all affected zones, based on Kosovo and Iraq post-conflict timelines.

Depleted Uranium Half-Life
If DU munitions were used, the contaminated sites are permanently altered on any human timescale. U-238 has a half-life of 4.5 billion years — the age of the Earth.
The invisible war after the war
Every conflict leaves an environmental aftershock that is invisible in the news cycle but felt across generations. The children of Basra, Iraq, born near Gulf War I DU strike sites, show elevated rates of congenital anomalies that persist 35 years later. The olive groves of Kosovo still test positive for heavy metals.
Environmental damage is not collateral. It is a predictable, documented, and frequently ignored dimension of the cost of military operations. The Footprint exists because no other ledger counts this.
Methodology & Data Sources
Carbon emissions: SIPRI military carbon footprint model applied to confirmed operational data (aircraft types, sortie counts, naval vessel days at sea). Oil and gas fire emissions calculated from NASA FIRMS fire radiative power (FRP) converted to CO₂e using NOAA emission factors. Methane from South Pars converted at 86× GWP20 per IPCC AR6.
Fire data: NASA FIRMS (Fire Information for Resource Management System) provides near-real-time satellite fire detection. Crude oil burning rates estimated from fire radiative power and known facility throughput from EIA Iranian oil infrastructure database.
Marine contamination: ESA Sentinel-1 SAR imagery processed by Copernicus Emergency Management Service. NOAA Environmental Response Management Application (ERMA) spill trajectory modelling. Coral risk assessment from IUCN Coral Triangle Initiative baseline data.
Land contamination: UNEP post-conflict environmental assessment methodology applied to ACLED strike event locations. Heavy metal contamination radii from munitions impact modelling (HALO Trust / MAG standards). Agricultural land from FAO GAEZ database clipped to contamination zones.
All figures carry significant uncertainty due to active conflict access restrictions. Numbers will be substantially revised as post-conflict UNEP assessments are conducted. We show current best estimates clearly labelled.
