Iranian President Masoud Pezeshkian has called for international action to document and compensate for environmental damage caused by US-Israeli attacks on Iran, warning that wars undermine global efforts to combat climate change.

Addressing the 31st United Nations Climate Change Conference (COP31) in Turkey on Wednesday, Pezeshkian said armed conflicts were undermining global efforts to combat climate change and that their environmental consequences often persisted long after fighting ended.

"The environment is a silent victim of wars," he said, warning that the destruction of natural resources, air, water and ecosystems could affect generations to come.

Pezeshkian said US and Israeli attacks on Iran had caused significant environmental damage alongside their human and economic consequences, releasing large quantities of pollutants and greenhouse gases into the atmosphere.

Citing assessments, he said an attack on fuel facilities in Assaluyeh in southern Iran had resulted in the release of approximately 500,000 tonnes of carbon dioxide, while strikes on fuel storage facilities in and near Tehran had caused emissions of around one million tonnes.

He described the figures as a contradiction of international efforts to curb greenhouse gas emissions, arguing that military operations involving fuel consumption, explosions, infrastructure destruction and widespread fires could undermine years of climate action.

The Iranian president also said protected areas and environmental ranger stations had been targeted during the recent attacks, describing such incidents as damage to the shared natural heritage of present and future generations.

He called for stronger international mechanisms to document environmental destruction resulting from military operations, prevent similar incidents and hold those responsible accountable.
