US and Israel’s war on Iran is a disaster for the environment, analysis shows

Military operations involving the United States and Israel in Iran generated an estimated 5 million tonnes of greenhouse gas emissions within the first two weeks of conflict. This figure, released in an analysis on March 8, is comparable to the combined annual emissions of 84 low-emitting nations, significantly impacting the global carbon budget.

The primary sources of these emissions include the destruction of infrastructure and the substantial consumption of fossil fuels by military forces. Experts project that these emissions will continue to escalate, particularly if attacks on oil facilities persist.

Key Emission Sources Identified

Damage to civilian structures accounted for approximately 2.4 million tonnes of carbon dioxide equivalent (tCO2e). This destruction contributes significantly to the overall environmental footprint of the conflict.

Fuel consumption by military aircraft and support vehicles added 529,000 tCO2e. The operational demands of modern warfare necessitate extensive use of fossil fuels for transport and logistics.

Furthermore, the combustion of an estimated 2.5 million to 5.9 million barrels of oil from targeted storage depots released 1.88 million tCO2e. This highlights the direct environmental consequences of targeting energy infrastructure.

Additional Environmental Impact

Destroyed military hardware contributed an additional 172,000 tCO2e, while munitions accounted for 55,000 tCO2e. These figures underscore the broad range of activities that generate emissions during armed conflict.

The total emissions of 5,055,016 tCO2e over a 14-day period translate to an annual rate of 131,430,416 tCO2e. This annual equivalent is comparable to the total emissions of a medium-sized, fossil fuel-intensive economy such as Kuwait.

Global Carbon Budget Implications

This rapid increase in greenhouse gas emissions places additional strain on the remaining global carbon budget. Current projections indicate that this budget could be exhausted by 2028 if present emission rates continue.

The analysis emphasizes the substantial environmental cost associated with military engagements. Beyond immediate human and economic tolls, armed conflicts have profound and lasting ecological consequences, often overlooked in initial assessments.

Broader Context of Conflict Emissions

Historically, military activities globally have been significant contributors to greenhouse gas emissions, though often exempt from international climate reporting frameworks. The scale of emissions from this specific conflict underscores the urgent need for comprehensive accounting of environmental damage caused by warfare.

Understanding the full environmental impact of geopolitical tensions is crucial for global climate action. The data from this conflict provides a stark reminder of how quickly large-scale military operations can undermine efforts to mitigate climate change and achieve sustainability goals.

Future Outlook and Monitoring

Continued monitoring of emissions from ongoing conflicts is essential to accurately assess their cumulative environmental burden. The long-term ecological recovery from infrastructure damage and widespread pollution also presents significant challenges.

International bodies and environmental organizations are increasingly advocating for greater transparency and accountability regarding military emissions. This incident serves as a critical case study for future policy discussions on conflict and climate change.

Implications

Country Impact: The conflict's environmental toll in Iran includes extensive infrastructure damage and significant air pollution, potentially exacerbating public health issues and hindering post-conflict reconstruction efforts. Long-term ecological recovery will be a substantial challenge.

Industry Impact: The energy sector, particularly oil production and storage, faces direct environmental and economic consequences from targeted attacks, leading to potential supply disruptions and increased operational risks in conflict zones. This also highlights the environmental footprint of military logistics and hardware manufacturing.

Market Impact: Increased greenhouse gas emissions from the conflict could contribute to global climate change concerns, potentially influencing carbon markets and investor sentiment towards environmentally responsible investments. The disruption of oil supplies could also impact global energy prices and market stability.
