Global Economies Exposed: How the Iran War Reveals Dependence on Fossil Fuels

The Iran war has laid bare the world's reliance on fossil fuels, with oil prices reaching $110 a barrel and potentially rising to $150. This has significant implications for global food security, with food prices expected to leap further due to a fertiliser supply crunch.

The UN climate chief, Simon Stiell, noted that fossil fuel dependency is 'ripping away national security and sovereignty and replacing it with subservience and rising costs.' The world's top emitters are divided into two camps: those pursuing a low-carbon future and those determined to exploit their fossil fuel reserves.

China, the world's biggest emitter, is leading the charge for an electrified future, with renewables growing at record levels and clean energy driving a third of its GDP growth. India has also set ambitious targets, aiming to generate 60% of its electricity from low-carbon sources by 2035.

In contrast, countries like the US, Russia, and Saudi Arabia are benefiting from high fossil fuel prices, with the US oil and gas sector set for a $60bn windfall. The US under Trump stands out as a paradox, with emissions falling until last year but now facing a potential rollback of climate protections.

The war in Iran has also highlighted the need for a global transition to clean energy. As John Kerry noted, 'The future is being able to harness the power of electrons and send them where we need them, and use them where and when we need them.' Reducing methane emissions could cut temperatures by 0.3C by the 2040s, and a mandatory methane agreement may be necessary to avoid the worst impacts of climate change.
