We study fundamental and applied earth sciences relevant to capturing carbon dioxide directly from the atmosphere and durably storing it in geologic, bio-based and ocean reservoirs or in value-added products to create negative emissions. Nature-based solutions such as wetland restoration, for example, are an effective decarbonization solution to help mitigate climate change while providing ecosystem services to coastal communities. Our experts work to delineate the natural processes and management practices within wetlands that control carbon dynamics; and integrate environmental justice considerations, policy, and governance approaches to develop a framework and guidelines for incorporating coastal wetland restoration/conservation into local, state, and national adaptation plans.

Additionally, EGD researchers are investigating suitable silica-based rocks for use as soil amendments on agricultural landscapes to speed up carbon dioxide absorption using enhanced rock-weathering technologies. They are also developing models to help operationalize enhanced weathering applications by investigating the physical, chemical and biological conditions that enhance weathering rates.

They are also looking at how similar practices can reduce methane emissions in rice agriculture, and at how different amendments can impact soil water and plant dynamics.
