3 Questions: Leveraging carbon uptake to lower concrete’s carbon footprint

To secure a more sustainable and resilient future, we must take a careful look at the life cycle impacts of humanity’s most-produced building material: concrete. Carbon uptake, the process by which cement-based products sequester carbon dioxide, is key to this understanding. Hessam AzariJafari, the MIT Concrete Sustainability Hub’s deputy director, is deeply invested in the […]

Fieldwork class examines signs of climate change in Hawaii

When Joy Domingo-Kameenui spent two weeks in her native Hawaii as part of MIT class 1.091 (Traveling Research Environmental eXperiences), she was surprised to learn about the number of invasive and endangered species. “I knew about Hawaiian ecology from middle and high school but wasn’t fully aware to the extent of how invasive species and […]

New additives could turn concrete into an effective carbon sink

Despite the many advantages of concrete as a modern construction material, including its high strength, low cost, and ease of manufacture, its production currently accounts for approximately 8 percent of global carbon dioxide emissions. Recent discoveries by a team at MIT have revealed that introducing new materials into existing concrete manufacturing processes could significantly reduce […]

MIT Center for Real Estate advances climate and sustainable real estate research agenda

Real estate investors are increasingly putting sustainability at the center of their decision-making processes, given the close association between climate risk and real estate assets, both of which are location-based. This growing emphasis comes at a time when the real estate industry is one of the biggest contributors to global warming; its embodied and operational […]

The NCAA Tournament’s Overlooked Effect On The Environment

NewsOne Featured Video Source: Patrick Smith / Getty March Madness means 68 teams vying to become champion, Cinderella runs for a few underdogs and big business for the NCAA, which earns 85% of its annual operating budget during the men’s basketball tournament. But all of that comes at a tremendous cost: An estimated 463 million […]

Minimizing electric vehicles’ impact on the grid

National and global plans to combat climate change include increasing the electrification of vehicles and the percentage of electricity generated from renewable sources. But some projections show that these trends might require costly new power plants to meet peak loads in the evening when cars are plugged in after the workday. What’s more, overproduction of […]

Engaging enterprises with the climate crisis

Almost every large corporation is committed to achieving net zero carbon emissions by 2050 but lacks a roadmap to get there, says John Sterman, professor of management at MIT’s Sloan School of Management, co-director of the MIT Sloan Sustainability Initiative, and leader of its Climate Pathways Project. Sterman and colleagues offer a suite of well-honed […]

Celebrating a decade of a more sustainable MIT, with a focus on the future

When MIT’s Office of Sustainability (MITOS) first launched in 2013, it was charged with integrating sustainability across all levels of campus by engaging the collective brainpower of students, staff, faculty, alumni, and partners. At the eighth annual Sustainability Connect, MITOS’s signature event, held nearly a decade later, the room was filled with MIT community members […]

Titanic robots make farming more sustainable

There’s a lot riding on farmers’ ability to fight weeds, which can strangle crops and destroy yields. To protect crops, farmers have two options: They can spray herbicides that pollute the environment and harm human health, or they can hire more workers. Unfortunately, both choices are becoming less tenable. Herbicide resistance is a growing problem […]

Study: Smoke particles from wildfires can erode the ozone layer

A wildfire can pump smoke up into the stratosphere, where the particles drift for over a year. A new MIT study has found that while suspended there, these particles can trigger chemical reactions that erode the protective ozone layer shielding the Earth from the sun’s damaging ultraviolet radiation. The study, which appears today in Nature, […]

Improving health outcomes by targeting climate and air pollution simultaneously

Climate policies are typically designed to reduce greenhouse gas emissions that result from human activities and drive climate change. The largest source of these emissions is the combustion of fossil fuels, which increases atmospheric concentrations of ozone, fine particulate matter (PM2.5) and other air pollutants that pose public health risks. While climate policies may result […]

Study: Carbon-neutral pavements are possible by 2050, but rapid policy and industry action are needed

Almost 2.8 million lane-miles, or about 4.6 million lane-kilometers, of the United States are paved. Roads and streets form the backbone of our built environment. They take us to work or school, take goods to their destinations, and much more. However, a new study by MIT Concrete Sustainability Hub (CSHub) researchers shows that the annual […]

A more sustainable way to generate phosphorus

Phosphorus is an essential ingredient in thousands of products, including herbicides, lithium-ion batteries, and even soft drinks. Most of this phosphorus comes from an energy-intensive process that contributes significantly to global carbon emissions. In an effort to reduce that carbon footprint, MIT chemists have devised an alternative way to generate white phosphorus, a critical intermediate […]

Using combustion to make better batteries

For more than a century, much of the world has run on the combustion of fossil fuels. Now, to avert the threat of climate change, the energy system is changing. Notably, solar and wind systems are replacing fossil fuel combustion for generating electricity and heat, and batteries are replacing the internal combustion engine for powering […]

How to pull carbon dioxide out of seawater

As carbon dioxide continues to build up in the Earth’s atmosphere, research teams around the world have spent years seeking ways to remove the gas efficiently from the air. Meanwhile, the world’s number one “sink” for carbon dioxide from the atmosphere is the ocean, which soaks up some 30 to 40 percent of all of […]

The Department of Energy Is Coming For Your Gas Stove…To Replace It With A More Efficient One

SOPA Images / Contributor via Getty Just as Republicans have identified one’s method of cooking as the newest front in the culture wars, the Department of Energy has proposed efficiency standards for cooktop appliances for the first time, something few would care about if not for the absurd hysteria surrounding gas stoves. For the uninitiated, […]

To decarbonize the chemical industry, electrify it

The chemical industry is the world’s largest industrial energy consumer and the third-largest source of industrial emissions, according to the International Energy Agency. In 2019, the industrial sector as a whole was responsible for 24 percent of global greenhouse gas emissions. And yet, as the world races to find pathways to decarbonization, the chemical industry […]

Computers that power self-driving cars could be a huge driver of global carbon emissions

In the future, the energy needed to run the powerful computers on board a global fleet of autonomous vehicles could generate as many greenhouse gas emissions as all the data centers in the world today. That is one key finding of a new study from MIT researchers that explored the potential energy consumption and related […]
