Study finds limiting warming to 2 °C would require at least a $200/t carbon tax globally

Green Car Congress

Some will suffer greatly from climate change, while others may even benefit. These heterogeneous effects mean that different countries will have differing incentives to abide by the Paris Agreement, which aims to limit global warming below 2 °C relative to pre-Industrial levels. —Cruz & Rossi-Hansberg.

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.

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. Aviation emissions are an increasingly significant contributor to anthropogenic climate change.

UGA study finds black carbon aerosols from GDI engines will worsen public health, climate; need for GPFs

Green Car Congress

A strong absorber of solar radiation, black carbon exhibits significant climate warming properties. On the other hand, the reduction in CO 2 emissions associated with the enhanced fuel economy of GDI vehicles would yield a globally uniform negative radiative effect, estimated to be ?0.013 W/m 2 over urban regions.
