One of the topics in my advanced students' textbook was about "green profits": businesses switching practices to be more environmentally friendly and marketing new products based on the current trend of YAY SAVE THE PLANET. I found four relevant (and funny) TV commercials. I'm sharing them in order from (what I think) is the easiest for ESL students to understand (and for them to verbalize their comprehension).
If you want to use these videos, but don't have Internet in your classroom (like me), there are plenty of programs available that will rip video off of YouTube. The one I use on my laptop at home is the Google Chrome Youtube Downloader extension; at work, since the extension doesn't work (I don't know why?), I use Youtube Downloader HD.
GE's "Househugger" ad
"The Sky is Falling" PSA about CO2 emissions
Audi's "Green Police" Super Bowl ad (with guest star Cheap Trick!)
Green Planet Network's "Do Time With Green" ad
The kids (and my coworkers) responded the best to the "Green Police" one, but all of them went over pretty well. The animation on the "Househugger" commercial also elicited some "OMG!"/"Aw, cute!" reactions, as well.
