Jennifer Pett-Ridge is a senior staff scientist and group leader at LLNL who uses the tools of systems biology and biogeochemistry to link, identity, and function in environmental microbial communities. Recently awarded a DOE Early Career award to work on responses of tropical soil microbes to climate change, she has also pioneered the use of NanoSIMS isotopic imaging in the fields of microbial biology and soil biogeochemistry. Pett-Ridge has published over 60 peer-review articles, including a patent ROI for the “ChipSIP” approach linking microbial identity and function using NanoSIMS analysis of microarrays.

There is an urgent need to remove carbon dioxide (CO2) from the atmosphere to ensure climate security and resilience. In 2022, the United States set a goal of developing carbon dioxide removal (CDR) pathways that will remove CO2 from the atmosphere and store it at the gigaton scale (at least a billion tonnes per year). Alongside the larger national goal of rapidly reducing current greenhouse gas emissions (GHG), CDR provides a vital option for achieving net-zero emissions by 2050.
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 carbon dioxide (CO2) from the atmosphere and store it at the gigaton scale. R2R researchers evaluated various techniques for removing carbon dioxide (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.
