Not sure how competitive these are but FYI:
WASHINGTON – The U.S. Environmental Protection Agency (EPA) is currently accepting applications for environmental education projects under the agency’s Environmental Education Grant Program. The program works to engage communities across the country through a wide variety of educational projects that have a lasting impact on people’s health by facilitating environmental stewardship.. Projects in the past have engaged students in stream monitoring, created sustainable mentoring communities, and provided professional development to teachers on subjects including science, technology, engineering and math.
Eligible organizations include local education agencies, colleges or universities, state education or environmental agencies, tribal education agencies, 501(C)(3) nonprofit organizations, and noncommercial educational broadcasting entities working in education.
This competitive grants program will total $2.77 million. Each of the ten EPA regional offices will award two or three grants and one or two grants will be awarded from EPA’s headquarters in Washington, DC. Each award will be an estimated $75,000 to $200,000. EPA expects to award between 22 and 32 grants nationwide.
