Enhanced Weathering via Soil Amendments for Negative Carbon Emissions

Carbon Removal & Mineralization Program

Weathering of geological materials is well known to capture CO₂ from the atmosphere and convert it to mineral carbonates and soluble carbonate and bicarbonate species. Enhancing the rate at which those materials weather will clearly increase the removal of CO₂ from the atmosphere. The key knowledge gaps associated with these processes include the magnitude of...

Silicate Rock Amendments for Reduced Methane Emissions and Increased Carbon Storage in Rice Fields

Carbon Removal & Mineralization Program

This project aims to evaluate whether addition of silicate materials (rock dust and/or clean industrial by-products) to rice agriculture can have two simultaneously climate benefits, namely decreasing methane emissions while increasing soil carbon storage. The work proposed herein focuses on three tasks: 1) mesocosm experiments for evaluating key variables; 2) reactive transport modeling for process…

Coastal Wetland Restoration a Nature Based Decarbonization Multi-Benefit Climate Mitigation Solution

Carbon Removal & Mineralization Program

Nature-based solutions for climate mitigation, such as restoring wetlands, can help decrease atmospheric greenhouse gas (GHG) concentrations, slow climatic and environmental change (nature-based decarbonization solution) while providing additional ecosystem services to coastal communities. This project aims to (1) delineate the natural processes and management practices within wetlands that control C dynamics, and (2) integrate environmental…

Impact of Biochar Amendments on Soil Water and Plant Dynamics under different climatic years and agronomic practices

Carbon Removal & Mineralization Program

Negative carbon emissions from agricultural soils have been stressed as important but yet understudied piece to combat climate change. Similarly, the inclusion of waste-derived material, such as biochar in crop production is viewed as a natural climatic solution to mitigate CO₂ emissions in addition to promoting soil health. These positive benefits of biochar are attributed...
