Out of curiosity, I just had a look at the Dupont website.
Dupont are serious about "sustainability" - or one could get that impression from their glossy online pdfs. Cut 'n paste follows.

Products that Reduce Greenhouse Gas Emissions:
By 2015, DuPont will grow our annual revenues by at least $2 billion from products that create energy efficiency and/or significant greenhouse gas emissions reductions for our customers. We estimate these products will contribute at least 40 million tonnes of additional CO2 equivalent reductions by our customers and consumers.

Footprint goals
21 percent reduction: greenhouse gas emissions
6 percent reduction: water consumption in scarce and stressed areas,
15 percent down overall water consumption

Energy goals
19 percent reduction: total energy consumption since 1990
6.5 percent: total energy from renewables

CFU has some serious foot in the door here I would hope.
Dupont is a huge company operating in 80 countries.
