MIT report finds China’s actions on climate change crucial; argues for global economy-wide greenhouse gas tax

Green Car Congress

A new report from the MIT Joint Program on the Science and Policy of Global Change shows the importance of all major nations taking part in global efforts to reduce emissions—and in particular, finds China’s role to be crucial. C change by the end of the century. The various taxes would slow warming to 3.5,

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. We need both a policy like a carbon tax and to put more R&D money into renewables.

MIT study suggests carbon tax could help reduce US deficit, lower other taxes, reduce emissions

Green Car Congress

A new report from MIT’s Joint Program on the Science and Policy of Global Change suggests that a tax on carbon emissions could help raise the money needed to reduce the US deficit, while improving the economy, lowering other taxes and reducing emissions. They found that the tax would raise $1.5 They found that the tax would raise $1.5

Study finds climate-influencing cirrus clouds form around mineral dust and metallic aerosols; little evidence of black carbon

Green Car Congress

An interdisciplinary team from MIT, the National Oceanic and Atmospheric Administration (NOAA), and elsewhere has identified the major particles upon which cirrus clouds form. Cirrus clouds influence global climate, cooling the planet by reflecting incoming solar radiation and warming it by trapping outgoing heat. —Cziczo et al.

MIT study finds fuel economy standards are 6-14 times less cost effective than fuel tax for reducing gasoline use

Green Car Congress

In a study published in the journal Energy Economics , MIT researchers have found that a fuel economy standard is at least six to fourteen times less cost effective than a fuel tax when targeting an identical reduction in cumulative gasoline use (20% by 2050). Implications for energy and climate policy in the United States Karplus, V.J.,

Study finds large-scale ramp-up in biofuel crops could result in warming in some tropical regions, cooling in temperate and polar regions

Green Car Congress

Global land-use changes caused by a major ramp-up in biofuel crops—enough to meet about 10% of the world’s energy needs—could make some regions warmer, according to a new integrated modeling study by researchers from MIT and the Marine Biological Laboratory, Woods Hole.

New FOX method estimates black carbon emissions from civil aviation ~2.7 times higher than standard estimates

Green Car Congress

Using an alternative approach to determine the amount of black carbon (BC) emissions from civil aviation, researchers from the University of Cambridge, MIT, and Forschungszentrum Jülich have estimated that in 2005, total BC emissions from this sector were 16.9 Barrett (2013) Global Civil Aviation Black Carbon Emissions.
