ERG alumnus Frank Errickson recently published research on Nature, “Animal-based foods have high social and climate costs”, quantifying the climate costs of animal-based agricultural greenhouse gas emissions at a regional level.
“Global food supply chains sustain a population of more than 7.8 billion people but produce over 26% of global greenhouse gas (GHG) emissions. Nearly 80% of these emissions are attributable to livestock production, and projections suggest that this sector’s contribution to climate change will increase as populations grow,” the research states.

ERG alumna Laura Moreno was recently featured on the California Magazine for her research on understanding food waste in the United States. Her study, which surveyed Nashville, Denver, and New York City, found that Americans throw out the equivalent of around $218 billion of food every year.
“The Bureau of Labor statistics estimates that the average American family spends $7,700 on food annually, $1,500 of which is discarded. The most wasted foods are fruits, veggies, and then leftovers and prepared foods,” she states.
ERG assistant professor David Anthoff and alumnus Frank Errickson recently published a report on Nature finding that “by accounting for economic inequalities between countries and regions, the social cost of methane drops by almost a factor of 10 in sub-Saharan Africa and jumps by almost a factor of 10 for industrialized countries, such as the United States.”
“President Biden’s action represents a much-needed return of science-based policy in the United States,” Anthoff states. “Devastating weather events and wildfires have become more common, and the costs of climate impacts are mounting.”
Congratulations to ERG Master’s student Jess Kersey and PhD student Annelise Gill-Wiehl for receiving the NSF Graduate Research Fellowship (GRFP), and newly admitted student Hilary Brumberg for an Honorable Mention! The NSF GRFP “recognizes and supports outstanding graduate students in NSF-supported STEM disciplines who are pursuing research-based master’s and doctoral degrees at accredited US institutions.”
In a recent Daily Cal article, ERG professor Dan Kammen was featured discussing a study from Lawrence Berkeley National Laboratory finding that commercial trucking is capable of undergoing major electrification. The researchers determined that “not only is electrifying regional and long-haul trucks a possibility, but it could offer a cost-effective energy supply for the commercial trucking sector. They also found that electrification could aid efforts to reduce global greenhouse gas emissions,” the article states.
“Electrified vehicles are just simply much cheaper to own and operate,” Kammen states in the article. “And it means that the path to zero carbon is just further clarified.”
ERG alumni Ranjit Deshmukh, Amol Phadke and associate professor Duncan Callaway recently had their research, “Least-cost targets and avoided fossil fuel capacity in India’s pursuit of renewable energy” published in the Proceedings of the National Academy of Sciences. Their analysis on India’s power usage, weather patterns and energy infrastructure was featured in the The Current, and suggests that the country is “well positioned to take advantage of green energy sources”.
The Energy and Resources Group Fall 2021 speaker series will resume August 25. Look for more updates on speakers and topics in August.
