Not really. It's the green crystal that was placed in Kal-El's ship by Jor-El. The final crystal he placed. It was kind of a "master control" crystal, containing all of the power needed to build the fortress of solitude and restore Superman's powers, if need be. Green Kryptonite is radioactive chunks of the planet that were not treated or prepared for such use.
