MIT team finds aviation emissions’ impacts on air quality larger than on climate

Green Car Congress

Researchers at MIT have determined that growth in aviation causes twice as much damage to air quality as to the climate. Aviation emissions are an increasingly significant contributor to anthropogenic climate change. They cause five per cent of global climate forcing.

UCL-led study finds climate impact caused by growing space industry needs urgent mitigation

Green Car Congress

The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. Effect of rocket launch and re-entry emissions on global climate forcing.

MIT Task Force on the Work of the Future suggests widespread autonomous driving at least a decade away

Green Car Congress

The MIT Task Force on the Work of the Future has released a new research brief examining the future of autonomous vehicles. Expansion will likely be gradual and will happen region-by-region in specific categories of transportation, resulting in wide variations in availability across the country.

MIT Looks Ahead to Hydrogen’s Aviation Future

Cars That Think

John Hansman , an aeronautics and astronautics professor at MIT and director of the university’s International Center for Air Transportation. And the hydrogen would have to either be produced through clean or nuclear energy to provide real climate benefits, the paper noted. asks Professor R. The first challenge is hydrogen production.

MIT study finds stiffer roadways could improve truck fuel efficiency

Green Car Congress

Now, a study by MIT researchers suggests that small changes in roadway paving practices could reduce that efficiency loss, at little to no cost. The study examined state-by-state data on climate conditions, road lengths, materials properties, and road usage, and modeled different scenarios for pavement resurfacing practices.
