Food without agriculture

Nature Sustainability | November 6, 2023

Edible molecules can be directly synthesized without agricultural feedstocks, saving land, water and GHG emissions. Dietary fats made from natural gas feedstock and average U.S. electricity would emit ~0.8 gCO2-eq/kcal (and 0 if using atmospheric carbon and renewable electricity) compared to 1-3 gCO2-eq/kcal from agricultural fat production.

Pathways to net-zero emissions aviation

Nature Sustainability | January 30, 2023

We assess nine possible pathways to achieve net-zero emissions from aviation, including changes and trade-offs in demand, energy efficiency, propulsion systems, and alternative fuels for both passenger and freight transport, as well as atmospheric carbon removal to offset non-CO2 radiative forcing.

Economic and biophysical limits to seaweed farming for climate change mitigation

Nature Plants | December 23, 2022

Global modeling shows that potential climate benefits of farming seaweed are large but sensitive to uncertain yields and competition with phytoplankton. We also find that carbon removal by sinking seaweed is much costlier than avoiding emissions by substituting seaweed for land-based crops.
