Mountain Horse Adventures uses biodiesel made from soy in all of its trucks and farm equipment, which in total use 100-200 gallons of fuel per year. Biodiesel provides significant greenhouse gas emission reductions as well as carbon monoxide, particulate matter, sulfate, hydrocarbon, and air toxic emission reductions.  Additionally, biodiesel is nontoxic, so it causes far less damage than petroleum diesel if spilled or otherwise released to the environment.  It is also safer than petroleum diesel because it is less combustible. 

The U.S. Department of Energy analyzed the full biodiesel life cycle and found that for every unit of fossil fuel used to produce biodiesel, 3.2 units of energy were gained. By contrast, petroleum diesel’s life cycle yields only 0.83 units of fuel energy.

Mountain Horse Adventures purchases weed-free hay.  Weed-free hay is hay which has been inspected and found to be free of noxious weeds. The company typically purchases about 40 tons of weed-free hay annually. Noxious weeds, once established, often take over natural wilderness and agricultural and recreational land. They can require millions of dollars in control efforts and often contribute to water quality and other environmental problems.

Mountain Horse Adventures also maintains riding trails by picking up garbage and conducting erosion maintenance.
