The aviation industry is facing increasing pressure to address its contribution to global greenhouse gas emissions, which are expected to grow significantly by 2050. To combat this challenge, the UK government and industry bodies have launched initiatives like the Jet Zero strategy and CAA Hydrogen Challenge. These efforts aim to achieve net-zero carbon emissions in domestic aviation by 2040. Substantial investments, including £113 million for hydrogen and all-electric flight technologies, are being made to support the transition to sustainable aviation solutions. The focus on hydrogen and other zero-emission technologies highlights a positive shift towards reducing the environmental impact of air travel and meeting sustainability goals.
