Penn sociologist Daniel Aldana Cohen thinks the U.S. needs a radical Green New Deal, so much so that he and three colleagues wrote a book about it.

"The age of climate gradualism is over, and in the 21st century all politics will be climate politics," Cohen says. "Going all-out means that no matter who wins the presidential election, there are going to be both victories and defeats. It's just guaranteed. We're not going to win every legislative compromise we want to win. That's why, in a way, we need such aggressive targets because we know we're not going to hit them all."

"A Planet to Win" arose organically after a series of interactions made it clear that Cohen and his co-authors—Kate Aronoff from The New Republic, Alyssa Battistoni of Harvard University, and Thea Riofrancos of Providence College—all felt the same about pushing for this economic and environmental movement. Though a broad Green New Deal would hit on a vast realm of factors, the researchers opted to focus on four in their book.

The first two—nationalizing the fossil fuel industry and creating a powerful low-carbon labor movement—go hand in hand. "In contrast to a lot of market mechanisms, the only real way to stop burning is to reduce their extraction. Public ownership is the way to do it," Cohen says. "Beyond that, we not only need to produce a just transition for workers in the , but we need to see green work as , caring for the planet and for humans."

Cohen spearheaded the chapter on the third subject, about reducing the amount of energy used in the United States and creating an efficient, effective clean-energy system.

"What does a national renewable energy system look like? How does that link to housing? Inside of that are a bunch of arguments about , , and public recreation," he says. He offers, as an example, shorter work weeks, which are part of a shift away from consuming and producing excessive material goods, toward more leisure time focused on play and social interactions.

The final recommendation chapter focuses on internationalism, starting with a discussion of a future with fully electrified affordable housing, a reduced energy demand, and use of "free no-carbon transit to travel for (less) work and (more) leisure, enjoying lovely parks, theaters, and landscapes," the authors write. "We'll need muscular social movements and insurgent policymakers to make this happen."

These ideas aren't pipe dreams, Cohen says, though to bring the Green New Deal to fruition, efforts already underway—such as low-carbon construction, retrofitting of homes, use of renewable energy, and cost-effective green housing—need to be scaled up and broadened. The time to act is now.

To that end, Cohen helped write and research the Green New Deal for Public Housing Act that U.S. Rep. Alexandria Ocasio-Cortez and Sen. Bernie Sanders (D-VT) introduced in November.

He's seen the national movement to guarantee safe, accessible, sustainable, permanent housing put Green New Deal ideals into practice. He's seen technical experts in areas like building materials take increasing interest in these social and political mobilizations. And most recently, he and Billy Fleming of the Stuart Weitzman School of Design co-authored a letter to Congress urging a Green Stimulus to put millions of Americans back to work after the COVID-19 pandemic subsides.

"The prospect of a recession caused by the coronavirus is terrifying," Cohen says. "But it will also force us to debate the terms of an economic stimulus. What kind of economy do we want to develop?"

This will hit every level of society, he adds. "Right now we need get the organizing right, the immediate relief of health issues and economic hardship right, and a Green Stimulus to recover. Then green investments could truly become common sense, and we'd just be fighting to accelerate them," he says. "I feel more optimistic about climate politics than I did five years ago. If we can get through this crisis, we could see massive changes that are greening the economy and making everyday life better. It's not anymore."

Ongoing work toward a greener economy

Sociologist Daniel Aldana Cohen and landscape architect Billy Fleming recently co-authored an open letter and call to action for members of congress to address three converging crises: the COVID-19 pandemic and the resulting economic recession, the climate emergency, and extreme inequality. The co-authors propose an ambitious $2 trillion green stimulus that "creates millions of family-sustaining green jobs, lifts standards of living, accelerates a just transition off fossil fuels, ensures a controlling stake for the public in all private sector bailout plans, and helps make our society and economy stronger and more resilient in the face of pandemic, recession, and climate emergency in the years ahead."

Cohen and Fleming are also co-authors on Green New Deal policy memos on mitigating the risk of climate change on public housing as well as on reducing greenhouse gas emissions through better urban and suburban transportation. Last autumn, Cohen, Fleming, and Kate Aranoff of Type Media Center brought together experts to discuss the Green New Deal in one of the largest climate events ever held at Penn.

Penn's Ian L. McHarg Center for Urbanism and Ecology also recently launched The 2100 Project, with the first installment, published as "An Atlas for the Green New Deal," consisting of more than 100 visualizations illustrating the projected spatial impacts of climate change and population growth in the United States.
