Prof. John Sterman speaks with Boston Globe reporter Alexa Coultoff about his experience retrofitting his home to achieve a fully net-zero house. “Sterman said he asked himself what actions would have the biggest payoff and went from there,” writes Coultoff. “For example, his home’s original windows from the 1920s were in rough shape, so he decided to tighten the building’s envelope, resulting in wider windowsills, where, added bonus, he can now display a robust plant collection.”

Prof. Emeritus Henry Jacoby writes for The Hill about the potential impact of the 2024 presidential election on climate change. “Laissez-faire, ‘do nothing’ climate policy is a recipe for present and future climate and societal harm,” Jacoby writes. “The climate system will not magically self-repair if we continue to pump greenhouse gases into the atmosphere.”

Fast Company reporter Adele Peters spotlights Boston Metal – an MIT startup that uses electrolysis to heat iron ore and create liquid steel without releasing carbon emissions. “If the process runs on renewable energy, the steel is zero-emissions,” explains Peters. “The same technique can be used to extract other valuable metals from mining waste.”

Researchers at MIT have developed a cathode, the negatively-charged part of an EV lithium-ion battery, using “small organic molecules instead of cobalt,” reports Hannah Northey for Energy Wire. The organic material, "would be used in an EV and cycled thousands of times throughout the car’s lifespan, thereby reducing the carbon footprint and avoiding the need to mine for cobalt,” writes Northey. 

Writing for The Hill, Principal Research Scientist Randolph Kirchain and Research Scientist Hessam Azarijafari address how the condition of the nation’s road system impacts transportation emissions. “Investing in a higher-performance road system is a lever within state control that will improve the efficiency and carbon emissions of all vehicles, regardless of how each is powered,” write Kirchain and Azarijafari. “Smoother, stiffer roads allow cars to travel along it more efficiently. Every time a car tire traverses a bump, crack, or pothole, energy is wasted.”

Prof. Jessika Trancik writes for Newsweek about the importance of government policy in supporting the transition to electric vehicles. “Policy is needed to make EVs widely accessible to people while the technology and markets continue to mature,” writes Trancik, “and to ensure the process moves quickly enough to help slow the build-up of greenhouse gases in the atmosphere.”

Prof. Jessika Trancik speaks with Associated Press reporter Alexa St. John to discuss electric vehicle emissions and ownership costs. Trancik notes, “buyers should consider total cost of ownership, which for an EV is generally less than that of a gas-powered counterpart due to savings on maintenance and fuel.”

Robert Stoner, interim director of the MIT Energy Initiative, speaks with Boston Public Radio hosts Margery Eagan and Jim Braude to discuss the climate crisis and some solutions being developed at MIT. "You have to be [optimistic]," says Stoner. "I do feel there are technological pathways that we can go down and get there. Solar and wind and storage get us an awful long way. We have to make these things cheaper, and there are an awful lot of people at MIT and at other great universities, and many companies, hammering away at those problems."

Cement production is a climate catastrophe, writes MIT Technology Review’s Casey Crownhart, pumping billions of metric tons of carbon dioxide into the atmosphere. Sublime Systems, a startup founded by MIT Prof. Yet-Ming Chiang and former postdoc Leah Ellis, uses electricity to trigger the chemical reactions that form the building material. Over the past few years, it’s gone from making palm-sized batches to producing 100 tons a year. The next stage is a commercial facility producing tens of thousands of tons of material a year. 

ClimateWire reporter John Fialka writes that MIT engineers have developed a new process to convert carbon dioxide into a powder that can be safely stored for decades. “The MIT process gets closer to an ambitious dream: turning captured CO2 into a feedstock for clean fuel that replaces conventional batteries and stores electricity for months or years,” writes Fialka. “That could fill gaps in the nation's power grids as they transition from fossil fuels to intermittent solar and wind energy.”

MIT researchers are working to uncover new ways to avoid contrails and minimize their impact on global warming, reports Nicolas Rivero for The Washington Post. “Whether [the contrail impact is] exactly 20 percent or 30 percent or 50 percent, I don’t think anybody knows that answer, really,” says research scientist Florian Allroggen “But it also doesn’t really matter. It’s a big contributor and we need to worry about it.”

Fast Company reporter Adele Peters spotlights how researchers at MIT have combined cement with carbon black to make concrete that can store energy as one of the climate tech innovations that provide hope “that it’s still possible to avoid the worst impacts of climate change.” With this new technology, “the foundation of your future house could eventually store solar power from your roof,” explains Peters.

Four faculty members from across MIT - Professors Song Han, Simon Johnson, Yoon Kim and Rosalind Picard - speak with Curiosity Stream about the opportunities and risks posed by the rapid advancements in the field of AI. “We do want to think about which human capabilities we treasure,” says Picard. She adds that during the Covid-19 pandemic, “we saw a lot of loss of people's ability to communicate with one another face-to-face when their world moved online. I think we need to be thoughtful and intentional about what we're building with the technology and whether it's diminishing who we are or enhancing it.”

Prof. Yet-Ming Chiang has been named to the TIME 100 Climate list, which highlights the world’s most influential climate leaders in business. “When it comes to cleantech, if it won’t scale, it doesn’t matter,” Chiang says. “This is a team sport—companies large and small, and governments state and federal, need to work together to get these new technologies out there where they can have impact.” 

Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the importance of scrappage programs, especially those that incentivize electrifying the current fleet of vehicles in the United States. “At any given point in time, you care about the composition of the fleet,” says Trancik. “Funding programs that would help turn over the fleet more rapidly makes a lot of sense.”
