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.

North American Countries Target “Super” Greenhouse Gases Through Strengthened Ozone Treaty

Green Car Congress

The US, Canada, and Mexico have submitted a proposal to strengthen climate protection under the Montreal Protocol— the international treaty that phases out the production of a number of substances responsible for ozone depletion. The proposal targets the production and use of HFCs, a group of “super” greenhouse gases. Source: IGSD.

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

Green Car Congress

And hydroxyls drive long chains of reactions involving other common gases, including ozone. That’s noteworthy because nitrogen oxides have primarily been associated with ozone formation and warming in the past. In the chemical soup of the lower atmosphere, however, sulfur dioxide isn’t the only substance interacting with hydroxyl.

OptiFuel finalizing $2.6M DOE grant to demonstrate RNG hybrid line-haul locomotive

Green Car Congress

OptiFuel has already developed and tested a high volume CNG/RNG refueling system at the Indiana Harbor Belt CNG locomotive program, utilizing low-cost CNG. These pollutants create very high levels of ozone, air toxins, greenhouse gases, fine particulate matter, and other diesel exhaust compounds classified as carcinogenic to humans.

Volkswagen to use CO2 as refrigerant for future air conditioning systems

Green Car Congress

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. It has a high cooling capacity and is available worldwide at low cost in the required qualities. CO 2 is an A1 refrigerant, indicating minimal toxicity and non-flammability.

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.
