I just discovered the EE site's grants page, and I am blown away--it's an amazing list, all relevant for North Carolina nonprofits.... Having sifted through other lists of grants to discover they weren't applicable for us or no longer in operation, your list is a mother lode of information. Thank you so much!
So check it out! There are a wealth of grants from small to large to support classroom projects, environmental education center programs, non-profit and community organizations and more. While you are there, don't forget to check out the Environmental Education Contests page as well! These provide great projects for students and can provide cash prizes in recognition of environmental education programs and initiatives.
