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. Even in this best-case scenario, reducing emissions comes with a steep price tag. 2012.04.007.

Energy researchers: clean US hydrogen economy is within reach, but needs a game plan

Green Car Congress

Addressing climate change requires not only a clean electrical grid, but also a clean fuel to reduce emissions from industrial heat, long-haul heavy transportation, and long-duration energy storage. However, they note, a clean US hydrogen economy will require a comprehensive strategy and a 10-year plan. —Arun Majumdar.

Researchers find consumers compensate for fuel-efficient car by buying bigger second vehicle; losing 60% of fuel economy savings

Green Car Congress

An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fuel economy standard policies by up to 60%. Just as Anderson et al.

MIT Report Outlines System-Oriented Coordinated Polices for Reduction in Light-Duty Vehicle Petroleum Use and Emissions

Green Car Congress

A new MIT report outlines a system-oriented set of coordinated policies to help the light-duty vehicle sector reduce petroleum-based consumption and its accompanying global warming emissions. We emphasize that this policy portfolio is not a substitute for an economy-wide carbon management policy (such as a carbon tax or cap-and-trade system).
