I don't know of any environmentalists against the research. Most I've talked with are skeptical that this is viable given current technology and believe that we need to act as if this doesn't exist, but that's different than opposing the research.

If there is some sort of breakthrough, then that's fantastic!

I think there are other geoengineering techniques that environmentalists are against such as seeding with sulphur dioxide or trying to create a shade preventing sun rays from reaching earth, but the argument against carbon capture is only that it doesn't yet exist.
