Best schools for environmental engineering/science?

I am currently a junior in high school and I am having trouble finding a college to match my needs. I am currently interested in environmental engineering, but most colleges tend to lump environmental engineering with civil engineering. Rather than focusing on building environmentally friendly structures, I am hoping to create (and perhaps implement) need-based solutions for the challenges we will be facing in the future relating to climate change. The program should also either have an emphasis on public policy or have some sort of political science minor available to supplement it. Ideally I would like the school to be strong in multiple environment related majors. Also, if you have any suggestions about what major would be more practical for these ambitions that would be awesome.

Requirements:
-20,000 undergraduate students at most (the 4,000-12,000 range would be ideal)
-Eastern half of the United States and Canada
-Strong internship/co-op program

These are also the schools I have looked at so far:
-University of Vermont
-The Eco League schools
-University of Pittsburgh
-University of Maryland College Park

-My GPA is a 3.56, but it has increased substantially from year to year.
-I took the new SAT and I was between the 91st and 93rd percentile
-4-5 APs overall (depending on what I take next year) and more honors/advanced classes
-Involved in some organizations such as Best Buddies and Special Olympics

Edit: also I’m planning on pursuing a masters so that may affect any input you may give

SUNY College of Enviromental Science and Forestry. My friend goes here and is interested in environmental engineering

It will be a reach, but check out Tufts.

It has lots of interdisciplinary programs spanning engineering, science and policy. The engineering school is small, so research is organized around interdisciplinary themes (rather than traditional disciplines) and one of them is sustainability.

Tufts was the initiator of the original university sustainability agreement and just recently hosted a conference to celebrate the 25th anniversary of its signing.

The current head of the EPA is a Tufts alum

A Nobel Peace Prize winning professor (for the IPCC report on climate change) just retired from Tufts Fletcher School of Law and Diplomacy to become a research professor in the Chemical Engineering Department

If you find that you are interested in Tufts, then Community Service, passion and essays are very important in the admissions process.

Good luck in your future endeavors - we need more people who can span the boundary between engineering and policy!
