Perspectives in 2024

Additive manufacturing is gaining growing attention as an alternative to conventional methods, but it can support more-sustainable manufacturing processes if developed through a system-level approach. This Perspective discusses how to achieve such a holistic development of additive manufacturing systems for sustainability.

Designing and implementing effective carbon offset mechanisms is a complex and challenging process. This Perspective underscores the importance of transparency across the carbon-offsetting value chain and places it as a prerequisite for efficient offset mechanisms and, ultimately, carbon emissions reduction.

Global food supply chains drive ecosystem degradation and social injustices. This Perspective focuses on the ability of midstream actors operating between agricultural commodity producers and manufacturers of food products to improve supply chain sustainability.

Research on how to support human exploration and eventual habitation of outer space is advancing. However, while its aims are beyond our planet, space bioprocess engineering has practical sustainability applications here on Earth.

International policy is concerned about palm oil-induced deforestation, whereas Indonesia’s government and industry representatives emphasize the role that palm oil plays in support of the livelihoods of millions of smallholder local farmers. This Perspective discusses how smallholders can still be supported without incurring further forest loss.

Risks in globally interconnected socio-environmental systems are complex and efforts to study them are incomplete. This Perspective argues that risks should be considered as both a product of these systems and a force that rewires them through a variety of mechanisms.
