Kerry, Graham and Lieberman plan to unveil their bill next week.
There are several differences between the approaches.
Cantwell and Collins would cap carbon from "upstream" sectors like oil producers and coal mining companies.
The Kerry-Graham-Lieberman measure is under development, but they plan to create a cap-and-trade program applied to electric utilities that would later fold in other types of industrial plants.
Collins spoke Tuesday at an energy and climate forum hosted by the National Journal Group.
