UK targets carbon-neutral flights by 2050 amid challenges in offsetting aviation emissions.

The UK's Jet Zero initiative aims for carbon-neutral flights by 2050, with domestic flights and airport operations to be zero-emission by 2040. However, offsetting aviation emissions is challenging; one London-New York flight generates 309kg of CO2, equivalent to a year's absorption by 10 mature trees. Achieving this goal could require planting 100 billion trees annually. While sustainable aviation fuels and airspace modernization are being explored, the cost and feasibility remain uncertain.
