Environmental Engineering majors are kind of a specialty and hard to find in small engineering schools…
Tufts Engineering would be a reach (about 11% acceptance rate last year) but not as crazy as Stanford. Also, there is not as big of an Asian population, so that should help.
Undergrad engineering at Tufts is less than half the size of Stanford and graduate engineering programs at Tufts are around one tenth the size of Stanford. Tufts biggest grad programs are in the health sciences and are mostly located at the downtown Boston campus - which makes Tufts feel more like a LAC. The engineering culture is LAC-like and there is a net positive attrition rate between Liberal Arts and Engineering (i.e. more transfer into engineering than out).
Tufts has both Civil and Environmental Engineering Majors (in the same department, like Stanford) and both are ABET accredited (Stanford’s Environmental Engineering is not ABET accredited).
Tufts also has an Interdisciplinary Environmental Health major that is not ABET accredited.
Tufts also has ABET accredited Chemical and Mechanical Engineering Majors.
To gain maximum leverage across all of engineering, engineering research is organized around interdisciplinary themes rather than traditional disciplines. This means that Chemical and Mechanical Engineering will also have environmental components (since sustainability is one of the three research themes)

On the Liberal Arts side, there are also a couple of interdisciplinary majors related to the environment/health. The Environmental Studies Major has tracks that incorporate engineering. The Economics Department, despite not having a Phd program, is among the top environmental and energy economics research groups in the world.

There is also a central organization for Environmental activities across the University

The Fletcher School (which is co-located with the undergrad campus) sponsers a major energy conference each year.

The Boston area is a Clean-Tech hub so there are lots of opportunities for internships (including during the school year) and the largest Clean-Tech start-up incubator in the country is only a couple of miles away.

Tufts is a Questbridge school, and it meets full need. It is no-loan below around $40K.
