Gonville & Caius College Fellow Professor Rob Miller and his team at Aviation Impact Accelerator have just published a report entitled Five Years to Chart a New Future for Aviation.
The report outlines four goals which if implemented immediately and completed by 2050 would put us on the track to net zero aviation by 2050. The full report is available by clicking this sentence.
The Aviation Impact Accelerator is a global team of academic and industry experts who have the aim of finding ways to accelerate the path to net zero aviation.
Professor Miller is the Director of the Whittle Laboratory and Lead of the Aviation Impact Accelerator. The start of the report is replicated below.
Executive Summary
The aviation sector is at a pivotal moment in its history. Currently, only about 10% of the global population flies, a figure expected to grow as incomes rise. Yet, aviation already accounts for around 2.5% of global CO₂ emissions, and when non-CO₂ effects are included, its contribution to climate warming increases to approximately 4%. Despite ambitious pledges from governments and industry to achieve a net-zero aviation sector by 2050, the sector remains dangerously off track. Without swift and decisive action, we risk missing the opportunity to reach net-zero emissions by 2050 and delaying the crucial technological and business transformations needed.
While global leaders have endorsed a vision of net-zero carbon emissions for the aviation sector, current efforts fall short in both scope and speed. In some cases, proposed solutions could exacerbate the crisis, such as relying too heavily on biomass for jet fuel without managing its environmental impact. It is also crucial to address aviation’s broader climate effects, including the formation of persistent contrails. The stakes have never been higher: urgent action is needed to shift the sector onto a sustainable path.
This report outlines an ambitious five-year plan to chart that course. It establishes four pivotal 2030 Sustainable Aviation Goals, each targeting key leverage points with the sector. If these goals are not implemented immediately and achieved by 2030, the opportunity for transformation will slip away, leaving the world to face the escalating climate impacts of a rapidly growing aviation sector, which is projected to at least double by 2050.
