More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. Electric power generation is the greatest contributor to out-of-state pollution-related deaths, the findings suggest.
Source: MIT. Researchers from MIT’s Laboratory for Aviation and the Environment have concluded that ground-level PM 2.5 Steven Barrett, an assistant professor of aeronautics and astronautics at MIT, and colleagues have published their results in the journal Atmospheric Environment.

MIT researchers have built a model to simulate long-range atmospheric transport of polycyclic aromatic hydrocarbons (PAHs). The model that will be further developed as part of an NSF-funded project to track how chemicals get to remote Arctic environments. Persistent organic pollutants are chemicals of substantial international concern.
Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% —Steven Barrett, professor of aeronautics and astronautics at MIT and corresponding author. increase in block fuel burn.
Researchers at MIT have determined that growth in aviation causes twice as much damage to air quality as to the climate. —lead researcher Dr Sebastian Eastham, from the Laboratory for Aviation and the Environment in MIT's Department of Aeronautics and Astronautics. —Dr Eastham.
A study by a team from the University of Cambridge (UK) and MIT attributes ~8,000 premature mortalities per year to aircraft cruise emissions. However, recent regional modeling work indicates that cruise emissions may contribute a significant fraction of aircraft-accountable ground-level pollutant concentrations on a regional scale.
MIT researchers have discovered that lead concentrations in the Indian Ocean are now higher than in the northern Atlantic and northern Pacific oceans. But while leaded gasoline usage has decreased drastically in the last few decades, lead is still pervasive in the environment.
Researchers at MIT have developed a new bicycle rear wheel—the Copenhagen Wheel —that can capture energy from braking and deliver the power back to provide a boost.

The MIT Energy Initiative (MITEI) has released a report on the proceedings—and papers that informed those proceedings—of the 8 April 2010 symposium on The Electrification of the Transportation System: Issues and Opportunities. The symposium was sponsored by the MIT Energy Initiative, together with Ormat, Hess, Cummins and Entergy.
Felzer and colleagues from the Massachusetts Institute of Technology (MIT) in Cambridge and the Marine Biology Laboratory in Woods Hole, Mass., Plants that release less water also take less of it from the environment. Our environment and quality of life depend on less uncertainty on this front. —co-author Cronin, J. Melillo, D.
Two of the largest emitters of these pollutants are vehicles and electricity generating units (EGUs), with some of the most densely populated regions in the US still failing to meet the National Ambient Air Quality Standards after 30 years of regulation. Tammy Thompson, (now at MIT), lead author. Tammy M Thompson et al.
In the study, conducted in collaboration with researchers from the University of Warwick and MIT, and published in Proceedings of the National Academy of Sciences (PNAS), the scientists measured the amount of hydrocarbons in a range of laboratory-grown cyanobacteria and used the data to estimate the amount produced in the oceans.
And well be able to conduct long-term studies that track the vital signs of apparently healthy individuals as well as the parameters of their environments. We started that work with Akinwande of UT Austin in collaboration with Roozbeh Jafari of Texas A&M University (now at MITs Lincoln Laboratory).
A recent white paper by Leslie Bromberg of MIT’s Plasma Science and Fusion Center and Wai K. It is a high octane fuel with combustion characteristics that allow engines specifically designed for methanol fuel to match the best efficiencies of diesels while meeting current pollutant emission regulations. It is a safe fuel.
Mineta specifically points to the success of the significant reductions in pollutant emissions from passenger cars during the past three decades in response to ever-stricter limits set by state and federal regulators. Impact of different sales mix on new car average fuel economy.
Lead is still pervasive in the environment despite the slow phasing out of leaded fuels, according to new research from the Massachusetts Institute of Technology (MIT). Leaded petrol has long been banned in many countries, after it was linked to neurological and cardiovascular illnesses.
The MIT will develop a new generation of power electronics based on vertical gallium nitride (GaN) superjunction diodes and transistors that can vastly exceed the performance of today’s GaN power devices. Massachusetts Institute of Technology. 8" GaN-on-Si Super Junction Devices for Next Generation Power Electronics - $4,521,601. UC Berkeley.
the session counted among its panelists: Professor John Heywood, Sun Jae Professor of Mechanical Engineering and Director of the Sloan Auto Laboratory at MIT. Prof Cervero acknowledges “ that it is easier to get the pollution, rather than the people, out of the car ” and is a big supporter of car sharing. Still, Prof. Bandivadekar, A.,
“People were really interested in clean air and clean water, so I decided there would always be interest in the environment,” Crawford says. You study many areas in civil engineering, including structures, soils, transportation, and the environment,” she says. She switched her major to civil and environmental engineering.
Many of you also mentioned how EVs are greener because they don’t pollute with tailpipe emissions. of Energy to Yale and MIT , that EVs are better for the environment from cradle to grave.) Side note: There are lots of studies, from the EPA and Dept.
It’s human frailty being replicated in the online environment. Brooks, an MIT robotics professor and cofounder of iRobot , said robots can help mitigate the effects of climate change and could help in caring for the elderly. “We I’m not surprised this is happening. The hard part is figuring out what to do about it.”
” The MIT report said that natural gas should be seen as a “ bridge ” to a low-carbon regime, rather than as the ultimate long-term solution itself. MIT: The Future of Natural Gas. Separately, the International Energy Agency (IEA) released its own report exploring the potential for a “golden age” of gas. Source: IEA.
Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The Future of Natural Gas: An Interdisciplinary MIT Study.
In 2017, when many carmakers were promising that fully autonomous vehicles would be on the road imminently, I wrote in MIT Technology Review : KITT, the car from Knight Rider , will remain the gold standard for autonomous vehicles. to San Francisco, which is a more complex driving environment. That was then and this is now.
Finally, the proposal delineates a land use and transportation infrastructure layout that enhances efficiency and community, while minimizing energy use, water pollution, and nonrenewable resource consumption. The town plan and transportation system proposed here offers a safe, convenient, clean, and pleasant environment.
CONCRETE TOMORROW At each stage of cement and concrete production, advances in ingredients, energy supplies, and uses of concrete promise to reduce waste and pollution. Sublime Systems , a startup spun out of MIT by battery scientists, uses electrochemistry rather than heat to make low-carbon cement from rocks that don’t contain carbon.
Researchers at MIT have developed a new detailed air-quality model to simulate the effects of physical, chemical, and meteorological processing of highly reactive trace species in urban areas. Urban regions account for an ever increasing fraction of Earth’s population, and are consequently an ever increasing source of air pollutants.
The objections they raised for years -- "no one is interested, no one would plug in, the technology is too complex, the benefits are minimal, its just shifting the pollution from the tailpipe to the smokestack, theres no demand for these cars" -- still show up occasionally, but are by and large history. Marketwatch ). Kwong asked.
Several years back, Ford engaged in a modelling strategy to determine what it’s fleet fuel economy should be over time given a proportional contribution to achieving an atmospheric CO 2 concentration of 450 ppm, said Sue Cischke, Ford group vice president, Sustainability, Environment and Safety Engineering. —Dan Kapp.
The third win—carbon dioxide (CO 2 ) pollution and oil imports would be reduced. The analysis used the MIT US Regional Energy Policy (USREP) model to evaluate the effect of a carbon tax as part of a Federal budget deal. This contributes to the win-win-win result we expected for the nation’s economy and environment.
