British Airways has revealed its most ambitious fleet renewal strategy to date, committing £7 billion over the next decade to transition its short-haul operations to hydrogen and electric propulsion.

The plan includes a partnership with ZeroAvia to develop hydrogen-electric powertrains for its domestic UK routes, with the goal of the first commercial zero-emission flights by 2030. The airline also plans to retrofit its existing wide-body fleet with advanced aerodynamic kits to reduce fuel burn by 15 per cent.

"We are not just buying new planes; we are reinventing the way we fly," said the CEO of International Airlines Group (IAG). "The era of sustainable aviation is no longer a distant prospect—it is starting now."

The announcement comes as the UK government considers a 'green aviation' tax credit system to incentivise airlines to move away from traditional jet fuels faster than global averages.
