Carbon Defense League

The "Carbon Defense League" (CDL), founded in 1998, is a group of tactical media practitioners whose projects include media actions on a variety of different media platforms including video, electronic hardware (i.e., the Nintendo Game Boy) and software. Relative to Institute for Applied Autonomy and CAE media activists, the CDL is comprised mostly of artists from the Carnegie Mellon School of Art and were active during 1999-2004 Fact|date=February 2007.

The CDL's mission:"The artist collective Carbon Defense League (CDL), founded in 1998, has used strategies such as online map making, workshopping, storytelling, hacking children’s toys, re-labeling items on store shelves, to create debate where it had previously been suppressed."

CDL uses the internet, mainstream media, video, and performance to stimulate public discussion about access to communication systems. They are responsible for a game for the Nintendo Game Boy which critiques traditional gaming models for young teens, the Gay Model hack for Maxis' SimCity, FtheVote.com, a satirical commentary of the U.S. voting process, and Re-Code.com, a website which aimed to elicit debate surrounding UPC codes by exploiting UPC symbols at supermarkets to reduce the price of brand names.
