国际航空航天协会表示, 飞机在2050年实现净零的主要障碍是技术推广缓慢, 而不是原料供应. SAF's main barrier to 2050 net zero is slow tech rollout, not feedstock supply, IATA says.

空运协会的一项新的研究发现,可持续航空燃料原料供应不是航空2050年净零目标的主要障碍,因为存在足够的可持续来源,如废油和生物量,不会造成有害的土地利用变化。 A new IATA study finds that sustainable aviation fuel (SAF) feedstock availability is not the main barrier to aviation’s 2050 net zero goal, as sufficient sustainable sources like waste oils and biomass exist without causing harmful land-use changes. 相反,主要挑战是生产技术的缓慢推出,特别是电力到液体系统,这需要大量投资和基础设施。 Instead, the primary challenge is the slow rollout of production technologies, particularly power-to-liquid systems, which require significant investment and infrastructure. 目前苏丹武装部队的产出主要依赖HEFA等有限的技术,而来自其他行业和不发达供应链的竞争进一步阻碍了进展。 Current SAF output relies mostly on limited technologies like HEFA, while competition from other industries and underdeveloped supply chains further hinder progress. 国际航空公司敦促各国政府提供政策支持,协调法规和长期激励措施,以加快SAF的部署. IATA urges governments to provide policy support, harmonized regulations, and long-term incentives to accelerate SAF deployment. 某些原料的可持续性仍然令人关切,例如与砍伐森林有关的牛肉高地,促使人们探索诸如侵入性沙沙藻等替代来源。 Concerns remain over the sustainability of some feedstocks, such as beef tallow linked to deforestation, prompting exploration of alternative sources like invasive sargassum algae.
