This area is not my area of expertise. But, it sounds as though you might want to look into an Environmental Design/Architecture degree. This list has 51 colleges with that major listed in IPEDS, including Berkeley, Davis, and Irvin among the UC campuses (if you’re a California resident).
This is a list of colleges offering a major in some iteration of natural resources & conservation.
But there are majors in Agroecology & Sustainability (UC Davis or Santa Cruz) or Sustainability Studies or any number of other possibilities.
I do think it would be beneficial for you to start digging in a little further to some of the majors to see what sounds interesting. But you’re also approximately 17 years old. Knowing that you’re interested in doing work related to the environment is great. You don’t need to know now what you major is going to be.
One major that I think you need to look closely at is environmental engineering. How do you feel about those classes? How do you feel about math and physics and chemistry, and doing lots of them? If you think that field remains a distinct possibility, then I would consider narrowing your focus to the 91 schools that are ABET accredited for environmental engineering, as most engineering firms only want to hire someone from an ABET-accredited program (and several Cali publics are on it). Of course, individuals who are accredited in civil engineering would also probably work, and there are many more of those programs (294 in the U.S.).
But I would find out your budget and see if you can see which majors actually interest you. (Again, it doesn’t have to be just one; it can still be several.) Then I’d start looking for schools that offer those majors, and go from there. We’ll be happy to help come up with schools once we have a bit clearer of an idea of what you might want (as well as budget, region of the country, budget, preferred university size, budget, type of experiences you’d like to have, budget, any activities you’d like to pursue, budget, etc.)
