With oil prices surging due to the ongoing conflict in Iran, the renewable energy advocacy group 350.org is renewing its call for a windfall profits tax on fossil fuel companies. The group warns that the supply shortage is leading to a global surge in coal production as countries scramble to meet energy demands, resulting in increased air pollution, climate chaos, and massive profits for coal producers.

Why it matters

The Iran war has exposed the vulnerabilities of global fossil fuel dependence, with ordinary consumers bearing the brunt of skyrocketing energy costs. A windfall profits tax on oil and gas companies could provide funding for the clean energy transition and offer relief to consumers, while also discouraging the expansion of dirty coal production.

The details

350.org found that countries like Japan, South Korea, Indonesia, Australia, and others have reversed plans to cut coal production or are increasing exports to meet the soaring global demand for energy. The group warns this will lead to higher pollution, more climate change impacts, and massive profits for coal producers at the expense of consumers.

  • The Iran war began in early 2026, leading to a supply shortage and price surge in global oil markets.
  • In recent weeks, US consumers have collectively spent $8.4 billion more on gas than they otherwise would have since the start of the war.

What they’re saying

“The Iran war is exposing the deadly consequences of global fossil fuel dependence. Coal producers are making massive profits while governments delay the clean energy transition. It's a stark reminder why windfall taxes on fossil fuel companies are more relevant than ever.”

— Anne Jellema, Executive Director, 350.org

“The Iran war shows what we have long warned: fossil fuel dependence creates crises, profits for polluters, and suffering for ordinary people. Windfall taxes on fossil fuel companies and accelerated deployment of renewables are urgent tools to turn this around.”

— Anne Jellema, Executive Director, 350.org

What’s next

Lawmakers in Germany and Australia are considering implementing windfall oil taxes to provide relief to consumers during the Iran crisis. In the US, the Big Oil Windfall Profits Tax Act has been reintroduced in Congress and could gain momentum as the war's impact on energy prices continues.

The takeaway

The Iran war has laid bare the dangers of global fossil fuel dependence, with ordinary consumers bearing the brunt of skyrocketing energy costs. A windfall profits tax on oil and gas companies could provide crucial funding for the clean energy transition, while also discouraging the expansion of dirty coal production that is further exacerbating the climate crisis.
