Pls help: Majors for sustainability/climate action tech careers?

For context, I’m an upcoming freshman at UNC Chapel hill

Ive been rlly really interested in the renewable energy, clean tech industry/ technologies geared toward climate action (you get the idea) and planned on majoring in environmental studies at UNC which I was really excited about. Though, looking more into other people’s experiences, I hear many people have a rlly hard time getting jobs since the degree is much more broad compared to other schools like NCSU that allow really specific majors that may peak more to recruiters. I was thinking of double majoring in environmental studies and biomedical engineering in case opportunities are low with that degree alone, though I know the workload is more heavy. They offer a Sustainability minor and Engineering for Environmental Change, Climate, and Health Minor, but, of course, those are just minors. (I did strongly want to go into the engineering field, hence biomedical engineering)

Does anyone have any advice? Second thought was Env. Studies BA & applied sciences and engineering minor to still get the engineering skill set, but really would like any form of advice. TIA!!
