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 modeling study finds 52% of projected global population in 2050 will live in water-stressed areas

Green Car Congress

A modeling study by researchers at MIT projects that 5 billion (52%) of the world’s projected 9.7 A large portion of these regions already face water stress—most notably India, Northern Africa and the Middle East. Looking at the influence of climate change alone, the researchers find a different result. Schlosser, C.A.,

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

The new report, part of the World Energy Outlook (WEO) 2011 series, examines the key factors that could result in a more prominent role for natural gas in the global energy mix, and the implications for other fuels, energy security and climate change.

MIT researchers improve upon methods to model urban air pollution

Green Car Congress

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. These pollutants include anthropogenic aerosols, which have important climate and health implications.

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

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 first two reports dealt with nuclear power (2003) and coal (2007).

China Says It's Closing in on Thorium Nuclear Reactor

Cars That Think

According to the World Nuclear Association , the country is eyeing thorium MSRs as a source of energy especially for the northwestern portion of the country, which has lower population density and an arid climate. But even though France, India, Japan, Norway, and the U.S. Uranium or thorium fuel can be mixed into the coolant salt.

How EVs Are Reducing Carbon (CO2) Emissions

Blink Charging

As the world grapples with the pressing issue of climate change, it is evident that we need swift action to avert its worst impacts. As one MIT report found, on average, “a fully electric vehicle emits about 25 percent less carbon than a comparable hybrid car.” A straightforward switch can create a substantial positive effect.
