Green revolving funds can invest in a wide variety of projects and have supported projects that impact a university's carbon footprint or local environment. Examples of these projects include: installing technology that conserves water and electricity; improving campus recycling rates; instituting a campus composting program; increasing campus waste diversion from landfills; replacing a fuel source (e.g. converting campus plants to burn biomass or biodiesel instead of traditional fuel sources); and introducing behavioral change programs that raise student awareness of individual resource use.
