That's true. A lamentable opinion from the gf there that is wrong and bad in multiple ways, and anyone would be correct to be perturbed at the expression of such from a partner they had chosen, they thought, on a firm basis of shared principles.

And yeah, you're right, dismissing compliance with environmental regulations in principle on the basis that 'structural change' is the only important kind is a logical fallacy. And anybody has a right to make compliance with environmental regulations a strict rule of their ethics if that's what they feel. And if that was the only thing he were saying I don't think he'd really be in the wrong. Those things coming along with a broad dismissal of her stated discomfort and jumping right to the idea that she's lying about migraine triggers though... not a good look, and makes me inclined to interpret the rest of his stated argument with side-eye.
