TL;DR: In this paper, a comprehensive review of negative emissions technologies (NETs) is presented, focusing on seven technologies: bioenergy with carbon capture and storage (BECCS), afforestation and reforestation, enhanced weathering, ocean fertilisation, biochar, and soil carbon sequestration.

TL;DR: An in-depth assessment of the role of NETs in climate change mitigation scenarios, their ethical implications, as well as the challenges involved in bringing the various NETs to the market and scaling them up in time are clarified.

TL;DR: In this paper, the authors assess the literature on innovation and upscaling for negative emissions technologies (NETs) using a systematic and reproducible literature coding procedure, and find that while there is a growing body of innovation literature on NETs, 59% of the articles are focused on the earliest stages of the innovation process, "research and development" (RD appealing to heterogeneous users, managing policy risk, as well as understanding and addressing public concerns are all crucial yet not well represented in the extant literature.

TL;DR: In this article, the authors synthesize emission mitigation potentials across the consumption domains of food, housing, transport and other consumption, and find that the top 10 consumption options together yield an average mitigation potential of 9.2 tCO2eq/cap, indicating substantial contributions towards achieving the 1.5-2°C target.
