Scientist and designer
When he was featured in 2016, Jeremy Freeman was developing new tools and methods to help scientists better analyze brain data. Now he is executive director of CarbonPlan, a nonprofit organization that he founded in March 2020 to tackle the climate crisis through open-source data and research.
You’ve shifted gears since 2016. Tell us about it.
I moved very far from neuroscience, and I’m now exclusively working on climate change. Our focus [at CarbonPlan] is the scientific integrity and transparency of climate solutions. [We do] a combination of research on different areas of climate science and strategies for addressing climate change. We [also] produce a variety of resources and tools for both the research community and the public at large.
Despite being a radically different field, there are some interesting commonalities, in terms of the value of having very accessible, open, publicly available data that speaks to critical issues. [For climate change,] issues around both what is changing in the climate and how we might address that, in different strategies we might take. Having as much of that information be developed in the open, in a way that others can contribute to, and making work available for others to read and evaluate and criticize and engage with — those are [also] values I felt really strongly about in the world of biomedical science.
What CarbonPlan work are you most proud of right now?
We have done a lot of analysis identifying very specific ways in which the implementation of forest carbon offset programs [the planting or preservation of trees to attempt to compensate for carbon emissions] haven’t worked. We did a comprehensive analysis of the role of forest carbon offsets in California’s cap-and-trade program, which is a massive sort of market of offsets on the order of $2 billion, and we identified about $400 million worth of offset credits that in our analysis do not reflect real climate benefits because of errors in how they were calculated with respect to issues that involve fundamental problems in statistics and ecology.
That team effort, led by Grayson Badgley and Danny Cullenward, along with a lot of other work that we’ve done on the role of offsets, is really starting to change the conversation, and wake people up to the fact that these approaches to dealing with climate change haven’t been working.
What other questions are you looking at?
There’s an area known as carbon removal, which refers to any mechanisms that draw down CO2 from the atmosphere. And carbon removal is really, really complicated, because there are a lot of different ways to potentially accomplish that.… So that’s an area where we’ve been very involved, studying, analyzing, comparing. We helped write, edit and produce a book called the CDR Primer — carbon dioxide removal primer. It’s, of course, a publicly available resource.
Have recent social justice movements influenced your work?
Absolutely.… Climate change is so fundamentally an issue of equity and an issue of justice. The burdens of climate change are going to be borne by those who were not directly responsible for it, and those who in many ways have been responsible for it will be more able to avoid its impacts. And there’s a deep injustice in that.… How to think about that is an important aspect of our work.… We’re interested in finding a way to be really complementary to a lot of existing community efforts around these issues.
