The field of green studies is a multifaceted area of study that can encompass a variety of environmental studies topics. Students may explore sustainability practices in businesses, the political and economic impacts of cultural approaches to the environment and effective ways to negotiate environmentally-impacting policy changes.

Courses are individual classes that can be taken at universities, colleges, junior colleges, and trade schools worldwide. For even greater flexibility, many schools also offer online classes. Students can take individual classes or pursue degree programs.

Part time learning allows one to obtain part-time degrees even if one cannot attend school on a full-time basis. One can learn at his or own pace, gradually accumulating credits which count towards final qualification.
