摘要

航空旅行需求正在迅速增长，航空业正依靠技术将其增长对环境的影响分离开来。以瑞典为例，我们评估了2050年中距离航空旅行的绝对环境可持续性，并根据地球极限对航空业的环境影响进行了定位。我们采用了一个新的框架，整合了前瞻性生命周期评估和绝对环境可持续性评估方法。我们的研究结果表明，预计由电子煤油或液氢驱动的中距离航空旅行可能会对生命周期环境产生影响，超过全球气候变化和生物多样性损失阈值的几个数量级。根据瑞典的案例结果，为了使航空业在地球限制范围内发展，我们建议开展跨部门合作，以解决无化石能源供应对环境的影响，并制定包含更广泛环境问题的综合目标。鉴于经济增长不可能与环境影响脱钩，政策制定者和航空业应同时考虑支持技术发展和实施管理航空旅行需求的措施。

Can hydrogen-powered air travel grow within the planetary limits?

Air travel demand is rising rapidly and the aviation sector is relying on technology to decouple environmental impacts from its growth. Using Sweden as a case study, we assessed the absolute environmental sustainability of medium-distance air travel in 2050, positioning the aviation sector's environmental impacts in relation to the planetary limits. We employed a novel framework that integrates prospective life cycle assessment and absolute environmental sustainability assessment methodologies. Our findings suggest that projected medium-distance air travel powered by e-kerosene or liquid hydrogen could have life cycle environmental impacts that overshoot global climate change and biodiversity loss thresholds by several orders of magnitude. Based on our case results for Sweden, for aviation to develop within the planetary limits, we recommend cross-sector collaboration to address environmental impacts from fossil-free energy supplies and the establishment of integrated targets that incorporate broader environmental issues. Given the unlikelihood of decoupling growth from environmental impacts, policymakers and the aviation sector should consider concurrently supporting technological development and implementing measures to manage air travel demand.

期刊介绍： Sustainable production and consumption refers to the production and utilization of goods and services in a way that benefits society, is economically viable, and has minimal environmental impact throughout its entire lifespan. Our journal is dedicated to publishing top-notch interdisciplinary research and practical studies in this emerging field. We take a distinctive approach by examining the interplay between technology, consumption patterns, and policy to identify sustainable solutions for both production and consumption systems.
