Working Paper: Prospects and challenges for implementing land-based climate change mitigation in support of carbon dioxide removal in China

Mathieu Mal, Huiling Zhu, Francis X. Johnson, February 07, 2024

In this working paper, the authors present an overview of China’s greenhouse gas emissions and its land-based carbon stocks and flows, with a spotlight on potential for land-based mitigation technologies and practices (LMTs) for carbon dioxide removal, based on the published literature. They also provide an analysis of LMT-related policies and perspectives on LMT development and future trends from experts, with discussion and conclusions based on the policy analysis and experts’ insights.


Report: Large-scale carbon dioxide removal and dual accounting: Microsoft and Ørsted

James Burbridge, Wilfried Maas, A.J. Simon, Julio Friedmann, Carbon Direct, 2023

In this report, the Carbon Direct science team explores dual accounting on national ledgers and organizational inventories in the context of the collaboration between Microsoft and the Danish government, on which Carbon Direct served as a technical advisor. The report explains the key differences between problematic double counting—when two private entities claim credit for the same emissions reduction or removal—and functional dual accounting—when a private entity’s reduction is reflected on a national inventory.


Report: Exploring the carbon sequestration potential of rewilding in the UK: policy and data needs to support net zero

Leo Mercer and Ruth Gregg, Centre for Climate Change Economics and Policy & Grantham Research Institute on Climate Change and the Environment, November 2023

This report synthesises the current policy, technical considerations and debate pertaining to rewilding in the UK, with a focus on what contribution, if any, rewilded land can make to supporting the decarbonisation of land use. The provision of other environmental, biodiversity and social benefits across England, Scotland, Wales and Northern Ireland is also considered.


Report: The role of carbon dioxide removal in contributing to the long-term goal of the Paris Agreement

by Johannes bednar, Roert Höglund, Kenneth Möllersten, Michael Obersteiner, Eve Tamme, IVL Swedish Environmental Research Institute, December 2023

This report delves into the multifaceted dimensions of carbon dioxide removal methods. The report discusses the role of carbon dioxide removal methods in contributing to attaining the long-term goal of the Paris Agreement.


Working paper: Decarbonizing India: Harnessing Direct-Air-Capture (DAC) to Combat the Climate Effects of Coal

by Arnab Sinha & Arun Kumar Rajasekaran, 3rd International Conference on Coal Supply Chain and Technology, September 2023

The urgent need to address climate change and achieve carbon neutrality has led to the exploration of innovative technologies such as Direct-Air-Capture (DAC). In a country like India, where coal continues to be a significant component of the energy mix, it is essential to evaluate DAC as a potential solution for offsetting carbon emissions. This paper shall provide a qualitative analysis of the applicability and potential benefits of DAC in the Indian context, focusing on its role in achieving net-zero emissions.


Report: Roads to Removal in the United States

Roads2Removal, December 2023

The Roads to Removal (R2R) report is a national collaborative effort by more than 68 scientists, and 13 institutions that examines regionally specific opportunities to address the pressing issue of climate change and the urgent need to remove CO2 from the atmosphere and store it at the gigaton scale. R2R researchers evaluated various techniques for CDR at the county level based on factors such as feasibility, capacity, impact, and cost. Chapters in the report include Forests, Soils, Biomass Carbon Removal and Storage (BiCRS) and Direct Air Capture (DAC), as well as the feasibility and costs of transporting CO2 and storing it underground. The report also examines the environmental and socioeconomic co-benefits and the significance of avoiding and reducing negative impacts on people and the environment.


White Paper: Durable Carbon Dioxide Removal in India

Carbon Removal India Alliance, December 2023

India has the potential to provide 10-30% of the world’s durable atmospheric carbon dioxide removal (CDR). With a convergence of optimal natural assets, technological innovation, and policy momentum, India can not only achieve its climate objectives but also become a global leader in sustainable carbon management. The development of a CDR sector can provide jobs, income, and dramatically improve the agricultural system, while generating tens of billions in foreign exchange and export for India.


Report: Scaling Direct Air Capture (DAC): A moonshot or the sky’s the limit?

by Peter Webb , Hasan Muslemani , Mark Fulton , Nigel Curson, The Oxford Institute for Energy Studies, December 2023

Direct Air Capture technology coupled with geological storage (‘DACS’, also ‘DACCS’) has recently emerged as one of the main CDR needed to reach net-zero targets. If deployed at scale, DACS would result in ‘negative emissions’ which would preclude the need for riskier options to abate emissions, such as geo-engineering solutions. This study assesses the technical, engineering, materials and resource requirements needed to take the technology from its current megatonne level of deployment to the gigatonne level needed to achieve climate targets by 2050.
