of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions. Aviation accounts for 3.5% —Lee et al.

Even though air quality will deteriorate further in North America and Europe, in 2050 it will be significantly better than that experienced by the global average citizen. Northern India and the Arabian Gulf region, on the other hand, will suffer a marked increase in ozone levels. micrometers which are regarded as particularly harmful.

Among the findings of the report, “HFC-134a phase-out in the Chinese light-duty motor vehicle sector”, was that, considering the social cost of CO 2 e, up to 1 trillion RMB in costs (US$150 billion) required to address climate change could be avoided through 2050 by transitioning to low-GWP alternative MACs.

Ethane reacts with sunlight and other molecules in the atmosphere to form ozone, which at the surface can cause respiratory problems, eye irritation and other ailments and damage crops. A snapshot from a simulation of how Bakken oil field hydrocarbon emissions including ethane affect North American ground-level ozone concentrations.

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.
