General Electric has launched several short films on the web to tell the world that GE’s Ecomagination is serious about the environment since launching the branded products and marketing initiative a year and a half ago, reports ClickZ (via MarketingVOX).

The films can be found at the Ecomagination website and will be supported by a round of TV and print ads. GE markets 45 Ecomagination products, including desalination technologies, high-tech windmills and super-efficient locomotives; sales of these products have surpassed $20 billion.

Actor Kevin Kline narrates the four films. Eight more showcases are planned by mid-year. The videos and website were done by Manhattan-based Syrup, while GE agency of record BBDO handled all offline ads.

The global campaign will be supported by creative sponsoships: including Reuters’s digital stories on business and the environment and a $50,000 “Environmental Business Plan Challenge” with partner Dow Jones, inviting wannabe entrepreneurs to submit eco-friendly business ideas.

Finally, a college-focused Ecocollegechallenge.com was produced with MTV.
