DuPont: Daimler's failure to implement European sustainability directive will carry an environmental cost

DuPont claims Daimler's delay will result in higher greenhouse gas emissions.

DuPont co-developed HFO-1234yf in response to Europe’s MAC Directive, and the company markets and sells the refrigerant under the name Opteon™ YF. DuPont applies its scientific expertise to creating sustainable solutions that make a difference in the world and our commercialization of Opteon™ YF is a great example of this. Opteon™ YF is a scientific breakthrough that has a 99.7 percent lower global warming potential than the refrigerant it was developed to replace, and has potential to reduce emissions equivalent to using billions fewer liters of fuel every year.

DuPont (NYSE: DD) has been bringing world-class science and engineering to the global marketplace in the form of innovative products, materials, and services since 1802. The company believes that by collaborating with customers, governments, NGOs, and thought leaders we can help find solutions to such global challenges as providing enough healthy food for people everywhere, decreasing dependence on fossil fuels, and protecting life and the environment.
