9 times out of 10 when the topic of sustainable tourism comes up, Disney is used as an example or case study. They re-use a lot of resources as well as go through all the waste generated by guests and sort them by material so that it can be recycled. Most of their vehicles run on Compressed Natural Gas and some of the rides (at Disneyland at least) run on cooking oil that they use to make the fries. They also were extremely proactive in the shift to LED lighting. They do generate a decent carbon footprint but they are by no means trashy or irresponsible in terms of being "green".
Yeah, I know. I just got myself into a pissy mood about Disney leaving all the old junk behind. I still think it stinks and feel the need to berate them, despite all the "other stuff".
