Just Removals

Implementation of CDR raises questions about the fairness of the distribution of its burdens and benefits as well as the related decision-making processes.

Soils

Soil carbon sequestration is a vital strategy for carbon dioxide removal (CDR) and achieving greenhouse gas neutrality. This session will present a systematic review of soil carbon sequestration methods, discuss accelerated carbon storage in agricultural peatlands through water table management and the addition of carbon-rich substrates and iron sulphate, and explore strategies for utilizing biomass carbon. Additionally, we will examine the effectiveness of storing carbon in agricultural soils, focusing on the role of crop residues in supporting renewable carbon supply chains.  

Chair: Iain Donnison

Earth Systems Modelling 2

Understanding the role of carbon dioxide removal (CDR) within the earth system is crucial for effective climate mitigation. This session will focus on quantifying the effectiveness of CDR in reducing atmospheric CO2 levels, examining the coupled uncertainties between negative emission technologies and the transient climate response to cumulative CO2 emissions. Additionally, we will explore the parameterization of blue carbon in Earth system models to evaluate its potential for CDR and climate mitigation, alongside a modeling study of Sargassum mariculture in the South Atlantic Gyre for marine carbon sequestration.
