Environmentalism was traditionally a right-wing sentiment. It became lib-coded in the 20th century, when it was tied to leftoid shibboleths about colonialism, White racism, and White capitalist greed (which in turn made anti-environmentalism right-coded).
The potential exists for a right-left White alliance on the topic of environmentalism, but only if libwhites can pull the anti-racism scales from their eyes and accept that nonwhites are the primary despoilers of nature.
I doubt that ever happens, unless by some miracle judeo-propaganda evaporates from our culture like a dense choking zog-smog blown away with the prevailing winds.
