Iran War Spurs Clean Energy Growth, but Climate Change Fight Far From Won

Countries are turning to clean energy in response to the ongoing war against Iran, but it's unclear if this shift will be enough to combat climate change. More than 30 governments have implemented policies aimed at reducing their reliance on fossil fuels and increasing energy efficiency.

However, despite these efforts, global greenhouse gas emissions rose by 0.2% in the first half of 2026 compared to the same period last year. Climate TRACE reported that power sector emissions decreased, but this was offset by increased emissions from road transportation and shipping.

The war has caused a significant increase in oil prices, with fossil fuel importers paying an estimated $330 billion more than expected since February. Countries like China, the European Union, and India have been among those hardest hit by these price increases.

Experts say that while the Iran war may be driving growth in clean energy investment in some regions, such as the US, Europe, and India, it's still too early to determine whether this trend will continue. In fact, global clean energy investment declined by 10% in the first half of 2026 compared to the same period last year.

Some researchers argue that the war could ultimately be a net gain for renewables if countries continue to invest in clean energy and transition away from fossil fuels. However, others caution that it's too soon to say whether this shift will be sustained or if the increased emissions caused by the conflict will outweigh any benefits from the growth of clean energy.
