Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

degrees Fahrenheit) over the last century and is expected to warm significantly more in the future if nothing is done. The most immediate, effective and low-cost way to reduce soot emissions is to put particle traps on vehicles, diesel trucks, buses, and construction equipment. degrees Celsius (4.5 Dessler et al.,

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

Finally, our results demonstrate that improving our knowledge of aerosol-climate interactions is important not only for better understanding the aerosol contribution to past and future climate change, but even for correctly evaluating the effects of long-lived greenhouse gas emissions from methane-oxidant-aerosol interactions. Shindell et al.

Study Concludes that Rocket Launches May Need Regulation to Prevent Ozone Depletion

Green Car Congress

The global market for rocket launches may require more stringent regulation in order to prevent significant damage to Earth’s stratospheric ozone layer in the decades to come, according to a new study by researchers in California and Colorado. Darin Toohey.

Volkswagen to use CO2 as refrigerant for future air conditioning systems

Green Car Congress

The Volkswagen Group announced that it is choosing CO 2 as the future low global warming potential (GWP) refrigerant for its mobile air conditioning (MAC) systems. R134a replaced CFC-12 as the MAC refrigerant in the early 1990s due to the negative impact of CFCs on the Earth’s ozone layer. Earlier post.).

Lifecycle study finds that environmental impacts of silicon-anode Li-ion battery could be roughly comparable with conventional Li-ion battery

Green Car Congress

In particular, silicon nanowires (SiNW) are widely studied as a promising anode material for high-capacity LIBs due to its low cost of fabrication and volume production potential. As a result, high-capacity LIB technologies are currently under development at lab scale with silicon nanostructured anode materials.

House Chairmen Waxman, Markey Release Draft of Energy and Climate Legislation; Among the Many Provisions Are Cap-and-Trade, Harmonization of CAFE and California Vehicle Regulations, and Low Carbon Fuel Standard

Green Car Congress

These are low-cost reductions in global warming pollution that can be secured by devoting approximately 5% of the allowance value to the program. The draft allows covered entities to increase their emissions above their allowances if they can obtain “offsetting” reductions at lower cost from other sources. Strategic Reserve.
