Meeting climate goals will most likely require large-scale carbon dioxide removal, yet its sustainability implications remain poorly understood. Here, the authors conduct a prospective life cycle assessment of multiple negative emissions technologies and practices, integrating mineral resource, health, and absolute sustainability indicators to quantify impacts between 2030 and 2050. The comprehensive analysis reveals previously overlooked bottlenecks.
