Just as a reminder for those searching for jobs in the environmental law field, here are a few further places to look.
ELI's Employment and Fellowships Opportunities webpage http://www.eli.org/Associates/bb_jobs.cfm
Unfortunately, this page is only accessible to members of the ELI. Fortunately, if you are a full-time law student, you get the first year of membership on a complimentary basis. Check the membership webpage of ELI for more info.
The American Bar Association's Section on Environment, Energy and Resources also has an employment opportunities page
For international environment related jobs, one valuable place to check is the vacancies page for UNEP http://unep.org/vacancies/
Finally, it is possible search and set up periodic alert of job opportunities with international organizations through a State Department webpage https://iocareers.state.gov/Account/Home/Login
The page is designed to provide US citizens with better information/accessibility to job openings in the UN system.
