 This paper examined several different negative emission technologies and practices, NETPs, as part of efforts to limit global warming to 1.5 degrees Celsius. The authors identified 36 NETPs configurations, evaluating each one's technical maturity, economic feasibility, greenhouse gas removal potential, resource use, and environmental impacts. They then selected 16 NETPs that were both economically viable and environmentally friendly. These included forestation, soil carbon sequestration, enhanced weathering with alavine, and three modalities of direct air carbon capture and storage, DACCS. The authors concluded that these NETPs have the potential to play a key role in achieving the goal of limiting global warming to 1.5 degrees Celsius.
