Carbon dioxide removal (CDR) techniques, or negative emission technologies (NETs), are a suite of natural and technological pathways to remove and sequester carbon dioxide (CO₂) from the air. Unlike carbon capture and storage, these techniques remove CO₂ directly from the atmosphere or enhance natural carbon sinks.
A Special Report of the Intergovernmental Panel on Climate Change
This IPCC report identifies the restoration of coastal blue carbon ecosystems as a response option to mitigate climate change through increased carbon uptake and storage.
This paper investigates whether BECCS, afforestation/reforestation, and enhanced weathering would cause moral conflicts regarding the human right to adequate food if implemented on a scale sufficient to limit global warming “to well below 2 C”.
This paper provides an assessment of the U.S. Department of Agriculture’s (USDA) existing programs and organizational structure, its capacity to support research and demonstration of CDR, and recommendations for expansion of these capabilities.
Drawing on empirical evidence from federal proceedings, this paper assesses how climate measures, models, targets, and thresholds have shaped the trajectory of geoengineering within U.S. climate policy between 1990 and 2015.
This paper argues that an 'overshoot and peak-shaving' strategy comes with a risk of escalating ‘climate debt’ and explains its position using an analogy of subprime mortgage lending.
This report makes the case that India and Canada must work together on geoengineering governance in advancement of climate goals, while seeking to collaborate on new carbon-materials industries to harness the potential of terrestrial geoengineering.
This is the introductory article from a special issue of the journal Ethics, Policy & Environment that highlights the ethical lessons central to geoengineering research, policy and governance.
This paper focuses on the role of indigenous peoples in the geoengineering discourse and frames the challenges with identifying indigenous consent to geoengineering activities.
This report assesses the current state of affairs surrounding technological CDR in the United States and provides concrete policy recommendations for action at the Federal level.
The objective of this analysis is to review the historical baseline estimates of federal RD&D investment related to carbon removal and assess how they compare with the recommended future funding levels from the 2018 National Academies Report on NETs.
