Human and planetary health implications of negative emissions technologies.

ABSTRACT: Meeting the 1.5 °C target may require removing up to 1,000 Gtonne CO₂ by 2100 with Negative Emissions Technologies (NETs). We evaluate the impacts of Direct Air Capture and Bioenergy with Carbon Capture and Storage (DACCS and BECCS), finding that removing 5.9 Gtonne/year CO₂ can prevent <9·10² disability-adjusted life years per million people annually, relative to a baseline without NETs. Avoiding this health burden-similar to that of Parkinson's-can save substantial externalities (≤148 US$/tonne CO₂), comparable to the NETs levelized costs. The health co-benefits of BECCS, dependent on the biomass source, can exceed those of DACCS. Although both NETs can help to operate within the climate change and ocean acidification planetary boundaries, they
