Two ERG Alumni Named Top 50 Green Innovators and Influencers by Grist Magazine

Sam Arons (MS ’07) and Joshua Apte (PhD ’13) were named as the 2019 “Grist 50” — a list of the most innovative and influential leaders in sustainability. Grist is an online environmental magazine and annually releases a list of high achieving “world fixers”.

As the director of sustainability at Lyft, Arons is working toward making Lyft fully carbon neutral and 100% reliant on renewable energy sources. Apte is an assistant professor at the University of Texas at Austin and uses methods from environmental engineering, aerosol science, exposure assessment, and environmental health to study human exposure to air pollution in urban environments.

Alumna Laura Schewel Talks Transportation Analytics in ITS International

The January/February 2019 edition of Intelligent Transportation Systems (ITS) International features an interview with ERG alumna Laura Schewel (MS ’11). Schewel is the CEO of Streetlight Data, a transportation analytics company she founded while at ERG. Streetlight Data uses anonymous cellular and GPS navigation data to study transportation patterns and develops analytical software to be used by municipal and regional planning authorities, as well as private companies and firms.

Schewel discusses how Streetlight Data fits into the planning process, emphasizing the need to educate decision-makers and ensure solutions are not only well-informed and comprehensive, but politically realistic. The company recently incorporated pedestrian and cyclist analytics into their flagship Streetlight Insight platform. On this new addition, Schewel comments, “My hope is that by being able to measure bikes and pedestrians, we can manage towards a future where these modes of travel are more prevalent.”

ERG Alum Patrick Gonzalez Testifies Before Congress as Expert Witness

During a recent House Natural Resources Committee event titled “Climate Change and Public Lands: Examining Impacts and Considering Adaptation Opportunities,” ERG alumnus Patrick Gonzalez (PhD ’97) provided testimony as an expert witness on climate change.

As an associate adjunct professor in the Department of Environmental Science, Policy, and Management and principal climate change scientist with the US National Park Service, Gonzalez researches the effects of anthropogenic climate change and develops natural resource management policies that incorporate findings from climate change science. He has also been a leading author for the Intergovernmental Panel on Climate Change (IPCC), which one the 2007 Nobel Peace Prize.

Gonzalez’s testimony focuses on the heightened susceptibility of the National Parks to climate change impacts, management solutions that can be used to mitigate these effects, and the broader-scale steps that must be taken in order to limit further exacerbation of climate change.

The full hearing may be viewed on the House Natural Resources Committee Democrats’ YouTube page and Gonzalez’s written testimony is available on the committee’s website. Coverage from the College of Natural Resources may be found here.

Isha Ray Comments on Issues Facing Clean Water Technology Implementation

In a recent article from Knowable Magazine, ERG faculty Isha Ray provides input on why many water filtering and purification technologies fail to produce significant impacts on community health in developing areas, despite extensive laboratory testing.

“One thing we know from the social sciences is people are not all the time driven only and exclusively by health considerations,” Ray states. She notes that the added task of treating water may be an additional load placed on individuals that already struggle to perform other intensive daily chores.

The original article can be found here, as well as a review on the subject co-authored by Ray in 2015.

Governor Newsom Appoints ERG Alum Carla Peterman to New Wildfire Recovery Commission

Governor Gavin Newsom’s office has released three appointments to the new Commission on Catastrophic Wildfire Cost and Recovery, which includes ERG alumna Carla Peterman (PhD ’17). Peterman served as a commissioner on the California Public Utilities Commission from 2013 to 2018.

She will be joined on the five-person commission by former California Insurance Commissioner David Jones, attorneys Michael A. Kahn and Pedro Nava, and director of Stanford University’s Climate and Energy Policy Program Michael Wara. The committee is tasked with preparing a report that assesses the impacts of catastrophic wildfires on California and recommends policy that ensures recovery costs are distributed in an equitable manner.

ERG student Hausfather in Science: Oceans are warming even faster than previously thought

Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean-heating observations. The results provide further evidence that earlier claims of a slowdown or “hiatus” in global warming over the past 15 years were unfounded.

“If you want to see where global warming is happening, look in our oceans,” said Zeke Hausfather, a graduate student in the Energy and Resources Group at UC Berkeley and co-author of the paper. “Ocean heating is a very important indicator of climate change, and we have robust evidence that it is warming more rapidly than we thought.”

Ocean heating is critical marker of climate change because an estimated 93 percent of the excess solar energy trapped by greenhouse gases accumulates in the world’s oceans. And, unlike surface temperatures, ocean temperatures are not affected by year-to-year variations caused by climate events like El Nino or volcanic eruptions.

The new analysis, to be published tomorrow (Jan. 11) in Science, shows that trends in ocean heat content match those predicted by leading climate change models, and that overall ocean warming is accelerating.

Study finds racial inequality in the deployment of rooftop solar

A new study by researchers at UC Berkeley and Tufts University shows fewer rooftop solar photovoltaics installations exist in African-American and Hispanic-dominant neighborhoods than in white-dominant neighborhoods, even when controlling for household income and home ownership. It was published in Nature Sustainability.

The study was conducted by Deborah Sunter (former postdoctoral scholar in Dan Kammen’s Renewable and Appropriate Energy Lab–RAEL, now at Tufts University), Sergio Castellanos of RAEL, and Dan Kammen, professor and chair of the Energy and Resources Group, professor in the Goldman School of Policy, and professor of Nuclear Engineering at UC Berkeley. .

ERG’s Lara Kueppers on Climate Change and CA Wildfires

ERG Professor Lara Kueppers recently commented in Bustle on the relationship between climate change and the California wildfires. 

“‘Due to climate change, she explains, ‘warm temperatures extend over a larger portion of the year.’ This, in turn, causes vegetation to dry out more quickly and for sometimes longer periods of time. ‘That essentially lengthens the fire season,’ she adds. ‘And the moisture in that vegetation has a lot to do with whether that fire will spread.'”

NPR Interviews Dan Kammen On U.N. Climate Convention

NPR’s Michel Martin interviewed ERG Professor Dan Kammen on the U.N. climate talks December, 2018 in Poland.

“Unfortunately, because the U.S. backed out, that’s left a number of holes. Essentially, the Paris conference was such a success because countries have been ramping up clean energy and becoming less expensive. But the U.S. and China, the two big holdouts, took major leadership positions in 2014, with President Obama and President Xi committing to very strong clean-energy strategies. And, of course, President Trump has now stepped out of that. And that’s left a big financing void of at least 20 billion a year against the committed or pledged totals. And we are seeing that only very few countries are actually on target to deliver on what they promised in Paris.”

ERG Student Chris Hyun Highlighted as InFEWS Fellow

InFEWS fellowships are granted to students whose PhD research aims to provide lasting environmental solutions and alleviate poverty in the world’s poorest regions. The Blum Center for Developing Economies recently sat down with four of its current InFEWS fellows to talk about the global challenges they are addressing, including ERG PhD student Chris Hyun:

“I recently completed a research project, working with water valvemen to help improve intermittent water systems and partnering with NextDrop and the Bangalore Water Supply and Sewerage Board. As I continue with my PhD research, I hope to uncover pro-poor sanitation solutions that have long-term impacts on food, energy, and water systems in urban contexts of low- and middle-income countries.”
