UK CCC warns Heathrow expansion could make aviation 80% of UK emissions by 2050

The UK Climate Change Committee (CCC) projects that, with Heathrow expansion, aviation could account for 80% of UK CO2 emissions by 2050, up from current levels. This highlights a policy conflict between infrastructure growth and net-zero targets, potentially forcing future trade-offs or offsetting measures. The claim is based on CCC analysis, but the exact modeling assumptions remain uncertain.
