The authors advocate that understanding the relationship between culture, policy, and funding can help the school leader interested in pursuing funds for a new school building or building retrofitting. Integral to this process is the development of school design policy that encourages and supports the concept of the green school as well as securing funding from federal, state, and local sources to sustain the green school in both design and operation. To facilitate the development of policies regarding green schools, agencies, governments, and countries are identified who have developed and implemented policies regarding the construction of green schools. Finally, funding efforts are identified including federal government, state government, non-profit, and business sources. It is imperative throughout the process of developing and constructing green schools that there is a consistent focus on the ability to sustain the green school in concept, design, and funding.
