I wonder how aligning with the conservative wing of global politics who are so aggressively against the climate change mitigation agenda shows he is "solidly for saving the planet".
That viewpoint is dying out in the conservative wings of global politics, it's still there, but it's not nearly as front and center, and the few times such views have been expressed to Elon from said conservatives, he's countered them. You don't have to agree with everything someone says to still agree with many things.
