Writing for Bloomberg, Prof. Carlo Ratti explores how street configuration and design can help reduce traffic speeds. “In studies we have conducted at our Senseable City Lab, we found that the posted speed limits often have little effect on how fast people drive,” writes Ratti. “Instead, the policies that work involve the design of the street itself.”
Work from the MIT Senseable City Lab is featured in the new “Urban Natures” exhibition at Harvard University’s Druker Design Gallery. The exhibit spotlights how MIT researchers are measuring tree canopy cover in cities as part of an effort to design cities that are more sustainable and livable. The lab’s Treepedia project “uses digital tools to keep tabs on urban tree canopies the world over,” writes Mark Feeney for The Boston Globe.
Writing for the Financial Times, Prof. Carlo Ratti makes the case that “in a hotter world, trees should be considered more than decoration. This ancient infrastructure can cool not just our buildings but the cities themselves. And with AI, we can now plant better, with precision urban forestry. In a warming world, the smartest climate tech may be rooted in the ground — and it doesn’t strain the power grid.”
Prof. Carlo Ratti speaks with The Boston Globe columnist Jason Schwartz about how a proposed seven-story office building behind Fenway Park could make the beloved Green Monster wall appear a bit less monstrous. “The wall has always felt monumental not just because of its size, but because it stood against an open sky,” says Ratti. “When the backdrop becomes a building, the view compresses, and the Monster might lose some of its presence.”
Prof. Carlo Ratti and the WeBuildGroup have developed a proposal to help rebuild the Francis Scott Key Bridge in Baltimore, Maryland, reports Anna Cooban for CNN. Ratti explained that the blueprint was designed to “produce a safer bridge by widening the channels through which ships can pass, among other measures.” The design will help prevent “the risk of a tragedy such as the one of March 26 happening again,” Ratti explains.
Financial Times reporters Andrew Hill and Emma Jacobs spotlight how Prof. Carlo Ratti and his colleagues have found that “people are traveling less far from their homes, consistent with more remote working.” The findings demonstrate a more flexible approach to commuting. “That’s good news [for cities], because the problem is not a problem of capacity, it’s a problem of peaks,” Ratti explains.
New York Times reporter Stephen Wallis spotlights Prof. Carlo Ratti’s proposal for the world’s first “farmscraper” in Shenzhen, China, a 51-story building that would be wrapped in a vertical hydroponic farm and could produce enough food annually to feed 40,000 people. “At this critical moment, what we architects do matters more than ever,” Ratti emphasizes. “Every kilowatt-hour of solar power, every unit of zero-carbon housing and every calorie of sustainably sourced vegetables will be multiplied across history.”
Writing for The Boston Globe, Prof. Carlo Ratti addresses New York’s congestion pricing plan – an attempt to prevent traffic build up and improve public transportation – and ways Boston can develop a similar and more effective policy. “With congestion pricing, the city and state can combat the climate emergency, the cost of living crisis, and improve quality of life,” says Ratti. “If they don’t take action now, something even worse will come to pass: Boston will find itself outdone by New York.”
Writing for Bloomberg, Prof. Carlo Ratti and Arianna Salazar-Miranda SM '16, PhD '23 explore the possibility and potential of developing 15-minute cities in America. “If implemented correctly, the 15-minute city can be an agent of freedom: freedom from traffic jams, freedom to live in a healthy environment and freedom to be outside,” they write. “It is not a one-size-fits-all solution, but our research shows that almost every community in America could benefit from a few more well-placed amenities.”
Writing for Financial Times, Prof. Carlo Ratti examines recent attempts to shorten journeys between major cities, such as a hyperloop system that would transport passengers via giant vacuum tubes from London to Paris in about 20 minutes. “Customers clearly prefer a smooth experience to maximum speed,” writes Ratti. “They might also be choosing the Eurostar for having a carbon footprint that is about 95 per cent less than that of aircraft. While the hyperloop might have emitted less per journey than a plane, and perhaps even a high-speed train, its construction would have had a huge environmental cost.”
Writing for The New York Times, Prof. Carlo Ratti and Harvard Prof. Edward L. Glaeser make the case that “the Bay Area needs a lot more housing, and we may need privately built cities to get there.” Ratti and Glaeser note, “building in the Bay Area will enable America to continue its history of allowing people to relocate to more productive places.”
La Biennale di Venezia’s Board of Directors has named Prof. Carlo Ratti as the curator for the 19th International Architecture Exhibition, reports DesignBoom. “Recognized as one of the leading scholars in urban planning, Ratti has co-authored more than 750 publications,” notes DesignBoom, adding that his, “involvement in curatorial projects spans various countries and prestigious platforms.”
Prof. Carlo Ratti has been named curator of the 2025 International Architecture Exhibition, the Biennale Architettura, reports Maria-Cristina Florian for ArchDaily. “We architects like to think we are smart, but real intelligence is everywhere,” says Ratti. “The disembodied ingenuity of evolution, the growing power of computers, and the collective wisdom of the crowd. To face a burning world, architecture must harness all the intelligence around us. I am honored and humbled to have the opportunity to curate the Biennale Architettura 2025.”
Writing for the Financial Times, Prof. Carlo Ratti explores the concept of the “15-minute city,” which is aimed at creating walkable neighborhoods. “The 15-minute city must be paired with investment in transport between neighborhoods,” writes Ratti, noting that investment is especially needed in public transportation to ensure that 15-minute cities do not contribute to greater segregation.
Prof. Carlo Ratti writes for USA Today about whether San Francisco is caught in a “doom loop,” a term that describes, “the city’s apparently unbreakable spiral of empty offices and unaffordable housing.” Ratti notes that “today’s crisis in the Bay Area could make room for new ideas to take hold faster than in other places. If the city seizes its moment, learning from its venture capital (VC) sector, San Francisco could also seize the future.”
