HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols. A total of approximately 100 flight hours are planned for the measurement flights in the emission plumes of Asian cities, said John P.

Sponsors of SAE Study Conclude HFO-1234yf Can Be Used As Low-GWP Global Replacement Refrigerant in MAC Systems

Green Car Congress

HFO-1234yf is a non-Ozone Depleting Substance with a Global Warming Potential (GWP) of 4. The results from the CRP1234 programs that investigated the new refrigerant for use in mobile air conditioning systems (cars and light trucks) are available on-line.

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. The performance-based standards for low GWP refrigerants in Europe and the United States allow automakers to choose a replacement for HFC-134a. transition to a new refrigerant is not easy.
