War in Iran spurs clean-energy policies but global emissions still rise

The February onset of the Iran war triggered renewable-energy and efficiency initiatives in over 30 countries, ranging from electric-vehicle incentives to electric-heat-pump upgrades. Regional responses vary: the United Kingdom saw a solar boom, Indonesia is replacing diesel plants with solar while expanding coal for heavy industry, and China’s investment decline drove the global downturn in wind and solar spending. Nonetheless, global greenhouse-gas output rose slightly, with road-transport emissions up while power-sector emissions fell.

Analysts warn that lasting climate impact requires sustained policy action, noting that fuel-tax cuts and continued fossil-fuel support blunt the transition. The conflict also raised fuel import costs by $330 billion, but nations that had previously invested in clean power saved billions in avoided imports. Overall, the war has nudged energy security thinking toward renewables, but the net climate benefit remains uncertain.
