How to decarbonize the world, at scale

The world in recent years has largely been moving on from debates about the need to curb carbon emissions and focusing more on action — the development, implementation, and deployment of the technological, economic, and policy measures to spur the scale of reductions needed by mid-century. That was the message Robert Stoner, the interim director […]

Forging climate connections across the Institute

Climate change is the ultimate cross-cutting issue: Not limited to any one discipline, it ranges across science, technology, policy, culture, human behavior, and well beyond. The response to it likewise requires an all-of-MIT effort. Now, to strengthen such an effort, a new grant program spearheaded by the Climate Nucleus, the faculty committee charged with the […]

MIT startup has big plans to pull carbon from the air

In order to avoid the worst effects of climate change, the United Nations has said we’ll need to not only reduce emissions but also remove carbon dioxide from the atmosphere. One method for achieving carbon removal is direct air capture and storage. Such technologies are still in their infancy, but many efforts are underway to […]

Bringing the environment to the forefront of engineering

In a recent podcast interview with MIT President Sally Kornbluth, Associate Professor Desirée Plata described her childhood pastime of roaming the backyards and businesses of her grandmother’s hometown of Gray, Maine. Through her wanderings, Plata noticed a disturbing pattern. “I was 7 or 8 when I caught wind of all the illness,” Plata recalls. “It […]

MIT design would harness 40 percent of the sun’s heat to produce clean hydrogen fuel

MIT engineers aim to produce totally green, carbon-free hydrogen fuel with a new, train-like system of reactors that is driven solely by the sun. In a study appearing today in Solar Energy Journal, the engineers lay out the conceptual design for a system that can efficiently produce “solar thermochemical hydrogen.” The system harnesses the sun’s […]

Cleaning up one of the world’s most commonly used substances

This past July, in the dusty basement of a building in Seattle, Washington, about 60 tons of concrete were poured as part of the renovation of a historic building. To an outsider, it looked like just another job site. Even to the workers pouring and shaping the concrete that day, it was more or less […]

Auto Industry News: California 300 Flings Dirt in Barstow, UAW Keeps Fight Alive in Detroit, and Self-Driving Gets Scrutinized in San Francisco

Another dramatic week for all corners of the auto industry. On the enthusiast side, off-road racing fans had a pulse-pounding weekend of excitement as the California 300 enjoyed its second annual run through the Barstow desert. Those on the business end watched union contract bargaining take an unexpected turn as GM negotiators swooped in with […]

Improving US air quality, equitably

Decarbonization of national economies will be key to achieving global net-zero emissions by 2050, a major stepping stone to the Paris Agreement’s long-term goal of keeping global warming well below 2 degrees Celsius (and ideally 1.5 C), and thereby averting the worst consequences of climate change. Toward that end, the United States has pledged to […]

How much energy does AI use compared to humans? Surprising study ignites controversy

AI’s carbon footprint is no open-and-shut case, according to scientists from the University of California-Irvine and MIT, who published a paper earlier this year on the open access site arXiv.org that shakes up energy use assumptions of generative AI models, and which set off a debate among leading AI researchers and experts this past week.  […]

New Volpe Center opens to support the country’s most innovative transportation projects

On a crisp Tuesday afternoon, representatives from MIT, the state and federal government, and the Cambridge community celebrated the official opening of the new John A. Volpe National Transportation Systems Center in Kendall Square. The ribbon-cutting ceremony was the culmination of nearly a decade of collaboration in which MIT designed and constructed the highly energy-efficient […]

How to tackle the global deforestation crisis

Imagine if France, Germany, and Spain were completely blanketed in forests — and then all those trees were quickly chopped down. That’s nearly the amount of deforestation that occurred globally between 2001 and 2020, with profound consequences. Deforestation is a major contributor to climate change, producing between 6 and 17 percent of global greenhouse gas […]

AI pilot programs look to reduce energy use and emissions on MIT campus

Smart thermostats have changed the way many people heat and cool their homes by using machine learning to respond to occupancy patterns and preferences, resulting in a lower energy draw. This technology — which can collect and synthesize data — generally focuses on single-dwelling use, but what if this type of artificial intelligence could dynamically […]

Jackson Jewett wants to design buildings that use less concrete

After three years leading biking tours through U.S. National Parks, Jackson Jewett decided it was time for a change. “It was a lot of fun, but I realized I missed buildings,” says Jewett. “I really wanted to be a part of that industry, learn more about it, and reconnect with my roots in the built […]

Harnessing hydrogen’s potential to address long-haul trucking emissions

The transportation of goods forms the basis of today’s globally distributed supply chains, and long-haul trucking is a central and critical link in this complex system. To meet climate goals around the world, it is necessary to develop decarbonized solutions to replace diesel powertrains, but given trucking’s indispensable and vast role, these solutions must be […]

Study suggests energy-efficient route to capturing and converting CO2

In the race to draw down greenhouse gas emissions around the world, scientists at MIT are looking to carbon-capture technologies to decarbonize the most stubborn industrial emitters. Steel, cement, and chemical manufacturing are especially difficult industries to decarbonize, as carbon and fossil fuels are inherent ingredients in their production. Technologies that can capture carbon emissions […]

Explained: The 1.5 C climate benchmark

The summer of 2023 has been a season of weather extremes. In June, uncontrolled wildfires ripped through parts of Canada, sending smoke into the U.S. and setting off air quality alerts in dozens of downwind states. In July, the world set the hottest global temperature on record, which it held for three days in a […]
