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.

Opportunities and Constraints for Biochar Technology in Australian Agriculture: Looking Beyond Carbon Sequestration

2014
Scholarly Work
Balwant Singh, Lynne M. Macdonald, Rai S. Kookana, Lukas van Zwieten, Greg Butler, Stephen Joseph, Anthony Weatherley, Bhawana B. Kaudal, Andrew Regan, Julie Cattle, Feike Dijkstra, Mark Boersma, Stephen Kimber, Alexander Keith, Maryam Esfandbod
This paper highlights that for biochar technology to be cost-effective and successful, Australia needs to look beyond carbon sequestration and explore other opportunities to value-add to biochar.

Umweltbundesamt, Options and Proposals for the International Governance of Geoengineering

2014
Think Tank Report
Ralph Bodle, Sebastian Oberthür, Lena Donat, Gesa Homann, Stephan Sina, Elizabeth Tedsen
In this research project for the German Federal Environment Agency, the Ecologic Institute develops specific proposals for the governance of the main currently discussed geoengineering concepts at the international level.

The Application of Biochar in the EU: Challenges and Opportunities

2013
Scholarly Work
Luca Montanarella, Emanuele Lugato
This paper reviews existing scientific evidence from a European policy perspective and identifies research gaps for future comprehensive assessments of the policy, environmental, economic, and health implications of the systematic use of biochar.

Exploring Negative Territory Carbon Dioxide Removal and Climate Policy Initiatives

2013
Scholarly Work
James Meadowcroft
This article explores the place for carbon dioxide removal in long term climate policy and considers nearer term policy issues.

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.

Regulatory Framework for Climate-Related Geoengineering Relevant to the Convention on Biological Diversity

2012
Scientific Report
Secretariat of the Convention on Biological Diversity
This study describes the current regulatory and legal framework that may apply to climate-related geoengineering, and identifies the gaps in science based global, transparent and effective control and regulatory mechanisms.

Greenhouse Gas Mitigation Potential of Agricultural Land Management in the United States: A Synthesis of the Literature

2012
Scholarly Work
Alison J. Eagle, Lydia P. Olander, Lucy R. Henry, Karen Haugen-Kozyra, Neville Millar, G. Philip Robertson

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.
