Carbon Dioxide Removal


Direct Air Capture

Direct air capture is the technique of scrubbing carbon dioxide directly from the sky through large mechanical facilities. The technique can be used to obtain carbon for making a byproduct or fuel. Direct air capture and storage (DACS) means storing that carbon dioxide in a long-term reservoir. The two main approaches involve either (1) liquids or surfaces that chemically interact with carbon dioxide, or (2) membranes that physically trap the carbon dioxide on solid surfaces.

Direct air capture of CO2 and climate stabilization: A model based assessment

2013
Scholarly Work
Chen Chen, Massimo Tavoni
This paper assesses the regional incentives in deploying DAC under different assumptions about international climate policy and introduces a “clean oil” market via DAC as a way to provide incentives to oil exporting countries.

Governance and Equity in the Development and Deployment of Negative Emissions Technologies

2012
Scholarly Work
Duncan McLaren
This paper presents a summary of results of the global assessment of the negative emission technologies (NETs) undertaken by the author for Friends of the Earth in the UK, with a focus on identified environmental justice and governance issues.

Considerations of Justice in Assessment and Appraisal of Negative Emissions Technologies

2012
Scholarly Work
Duncan P. Mclaren
This paper identifies several justice implications arising from the potential moral hazard in the development of NETs, the distribution of geological storage for carbon dioxide, and the competition for biological productivity for negative emissions.

Impacts of Climate-Related Geoengineering on Biological Diversity

2012
Scientific Report
Secretariat of the Convention on Biological Diversity
This study compiles and synthesizes available scientific information on the possible impacts of a range of geoengineering techniques on biodiversity, including preliminary information on associated social, economic and cultural considerations.

A comparative global assessment of potential negative emissions technologies

2012
Scholarly Work
Duncan McLaren
This paper provides a global assessment of around 30 prospective NETs, drawing conclusions on how NETs will contribute to safe carbon budgets, the governance challenges of NETs, and the potential role of carbon markets.

Remaking the World to Save It: Applying U.S. Environmental Laws to Climate Engineering Projects

2011
Scholarly Work
Tracy D. Hester
This Article examines how U.S. environmental laws might apply to climate engineering research and how the U.S. courts would review disputes over those projects.

Governing Climate Engineering: Scenarios for Analysis

2011
Scholarly Work
Daniel Bodansky
This report discusses the permissibility of geoengineering under international law and whether international norms matter in the scheme of geoengineering governance.

Geoengineering: A national strategic plan for research on the potential effectiveness, feasibility, and consequences of climate remediation technologies

2011
Think Tank Report
The Bipartisan Policy Center
This report presents the conclusions of the Task Force on Climate Remediation Research, which was convened by the Bipartisan Policy Center in 2010 to develop recommendations for the U.S. government on geoengineering research and oversight policy.

IPCC Expert Meeting on Geoengineering

2011
Scientific Report
Intergovernmental Panel on Climate Change (IPCC)
This meeting report summarizes discussions of three Working Groups to the IPCC's Fifth Assessment Report (AR5) on geoengineering, including carbon dioxide removal.

Systems Analysis and Cost Estimates for Large Scale Capture of Carbon Dioxide from Air

2011
Scholarly Work
A.J. Simon, Naluahi B. Kaahaaina, Julio Friedmann, Roger D. Aines
This paper explores the resource intensity and major cost elements of direct air capture of carbon dioxide.
