Carbon Dioxide Removal


Biochar

Biochar is a substance created when organic material like agricultural waste is burned in the absence of oxygen. That process, called pyrolysis, creates a carbon-rich product that is stable or biologically recalcitrant. By transforming biomass into biochar, the carbon in the plant material is locked up instead of being released into the atmosphere when the biomass is burned or biodegraded in soil. Biochar is added to soil to sequester carbon dioxide in the soil.

Negative emissions—Part 3: Innovation and upscaling

2018
Scholarly Work
Gregory F Nemet, Max W Callaghan, Felix Creutzig, Sabine Fuss, Jens Hartmann, Jérôme Hilaire, William F Lamb, Jan C Minx, Sophia Rogers, Pete Smith
This paper finds that if NETs are to be deployed at the levels required to meet 1.5 °C and 2 °C targets, then important post-R&D issues will need to be addressed, including incentives for early deployment, niche markets, scale-up, and demand.

Update on Climate Geoengineering in Relation to the Convention on Biological Diversity: Potential Impacts and Regulatory Framework

2016
Scientific Report
Secretariat of the Convention on Biological Diversity
This report provides an update, including regulatory developments, to the CBD's 2012 Technical Series No. 66: Geoengineering in Relation to the Convention on Biological Diversity report on the potential impacts of geoengineering.

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.

IPCC Expert Meeting on Geoengineering

2011
Scientific Report

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

A Coordinated Strategy Could Focus Federal Geoengineering Research and Inform Governance Efforts

2010
Scientific Report
United States Government Accountability Office
This report examines the state of geoengineering science, federal involvement in geoengineering, the extent to which federal laws and international agreements apply to geoengineering, and any governance challenges around geoengineering activities.

Geoengineering the Climate: Science, Governance and Uncertainty

2009
Scientific Report
The Royal Society
This report presents an independent scientific review of the range of geoengineering methods and introduces and addresses the key policy questions surrounding geoengineering that the international community needs to confront.
