An MIT-led study finds that technological advances alone will not bring about dematerialization, or the reduction of the amount of materials needed to produce goods and services.

Study: Technological progress alone won’t stem resource use

Researchers find no evidence of an overall reduction in the world’s consumption of materials.

Researchers report that warming from short-lived compounds — greenhouse gases such as methane and chlorofluorocarbons, that linger in the atmosphere for just a year to a few decades — can cause sea levels to rise for hundreds of years after the pollutants have been cleared from the atmosphere.

Short-lived greenhouse gases cause centuries of sea-level rise

Through warming effects, methane and other gases impact rising seas long after leaving the atmosphere.

“Compared to the developed world, the state of transportation systems in China is less well-understood, and because it’s such a large, populous country, unrestricted or poorly guided growth could lead to significant negative consequences for the environment and climate,” says Paul Kishimoto, a recent recipient of a fellowship from the Martin Family Society of Graduate Fellowships in Sustaina...

Rethinking how we get around

Paul Kishimoto, a PhD student in IDSS, probes the future of transportation in China.

A new MIT system first creates a graph of vehicles (circles) and ride requests (stars) in a city, and then uses a method called “integer linear programming” to compute the best assignment of vehicles to trips.

How ride-sharing can improve traffic, save money, and help the environment

Study shows carpooling apps could reduce congestion by a factor of three while still serving the same number of people.

A destructive wildfire burned through Canada’s Northern Alberta region, razing neighborhoods in Fort McMurray and displacing tens of thousands of residents.

Climate models may be overestimating the cooling effect of wildfire aerosols

Study finds accounting for year-to-year variability enables more accurate projections of climate change and its impacts.

A silver-based catalyst material with a porous honeycomb-like structure, developed by the MIT team, can selectively transform carbon dioxide (CO2) to carbon monoxide (CO).

Turning greenhouse gas into gasoline

New catalyst provides design principles for producing fuels from carbon dioxide emissions.

A new study by researchers at MIT and elsewhere has found that, rather than adopting a standard for automotive gas-mileage ratings, the EU could achieve the same results at far lower cost to the economy by simply extending their existing emissions-trading system to encompass transportation rather than just electricity generation and energy intensive industry.

What’s the best way for Europe to curb greenhouse emissions from cars?

Emissions trading would be more effective than mileage standards, new study shows.

ROBOAT, a new collaboration between researchers from MIT and partner institutions in the Netherlands, seeks to design and deploy a fleet of autonomous boats on the canals of Amsterdam.

An autonomous fleet for Amsterdam

MIT, AMS Institute will collaborate to solve complex urban problems for Amsterdam with the development of autonomous "roboats."

A study led by MIT researchers suggests that using mobile-phone data to track people’s movement provides a deeper picture of exposure to pollution in urban settings, compared to only studying air-quality levels in fixed places.

Measuring exposure to pollution

Mobile-phone data helps researchers study an urban problem in greater detail.

A team of researchers, including graduate student Maher Damak (left) and associate professor of mechanical engineering Kripa K. Varanasi, have found a way to drastically cut down on the amount of pesticide liquid that bounces off plants.

Reducing runoff pollution by making spray droplets less bouncy

MIT researchers find a way to make pesticides stick to leaves instead of bouncing off.
