I think you’re conflating ecological conservation and political conservatism. This seems like an argument that wouldn’t exist in a language that created a meaningful distinction between the two.
An individual that is protecting the rights of capital to cause rapid ecological damage, is doing so by seeking to preserve the power of private capital.
A leftist seeking to abolish the power of capital to conserve the environment is the radical in that case.
Communism through conservatism as I think you are describing it isn’t wrong, but it is at the very least confusing due to the clashing definitions of radical, conservative, and the targets of both changes and preservation of the structures.
Once again for the sake of clarity
Ecologic conservation, cultural/sociatal conservation ≠ economic conservatism.
Sticking the terms together is kinda just confusing
I think it’s best just to avoid the term conservative in general, similar to how I would suggest any socialists organization avoid using the term national socialist. Even if you can clarify the position, and linguistically its technically correct, the label of conservatism is just too loaded.
From our brief interaction It does sound like your views are heavily motivated by environmentalism, I haven’t done much reading on eco-marxism or eco-anarchists, but someone probably has come up with a decent dialectic analasys and some formal terminology. Then again we socialists tend to be shit at naming things do maybe not xD. I wish I could recommend some literature for you but it’s not a direction I’ve studied up on, but I’m sure someone can suggest a properly solarpunk book.
