The Society of Automotive Engineers (SAE) International Cooperative Research Program, sponsored by major automotive manufacturers including Chrysler, Ford, General Motors, Fiat, Jaguar, Land Rover, Hyundai, PSA, Renault and Toyota, recently released a report summarizing results of its industry evaluation of low global warming potential (GWP) refrigerant, hydrofluoro olefin (HFO)-1234yf, which was co-developed by DuPont.
The report validated that HFO-1234yf is safe to use in mobile air conditioning, and that, of all the proposed alternatives considered, HFO-1234yf has significant environmental benefits. The report concluded HFO-1234yf offers “the greatest potential to meet environmental and consumer needs.”
“DuPont is very pleased that SAE International and leading automotive manufacturers have recognized the benefits of HFO-1234yf,” said Cynthia C. Green, vice president and general manager – DuPont Fluoroproducts. “HFO-1234yf has a dramatically lower global warming potential than the R-134a refrigerant used today, and the best overall lifecycle climate performance globally, which makes it the preferred environmental solution. Since it is a near drop-in replacement for R-134a, it is also a practical choice, keeping costs down for both automakers and consumers at a critical time.”
Because of the lead times required for new car designs, global automotive manufacturers and suppliers have been working with industry experts and independent test laboratories since 2007, when the first SAE International Cooperative Research Program (CRP) was formed to investigate the safety and performance of HFO-1234yf for use in mobile air conditioning.The summary SAE CRP report is available on-line at:
DuPont – one of the first companies to publicly establish environmental goals 19 years ago – has broadened its sustainability commitments beyond internal footprint reduction to include market-driven targets for both revenue and research and development investment. The goals are tied directly to business growth, specifically to the development of safer and environmentally improved new products for key global markets.
DuPont is a science-based products and services company. Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere. Operating in more than 70 countries, DuPont offers a wide range of innovative products and services for markets including agriculture and food; building and construction; communications; and transportation.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
