Green fracing fluids are those fluids used in hydro-fracturing that are generally non-toxic in nature. Some examples of greening these fluids include:

• Removal of 2-Butoxyethanol. It is sometimes used as a solvent and has been criticized for possibly causing reproductive issues in animals.
• Discontinuing the use of fluorocarbons which have been cited as potentially being an environmental pollutant.
• Substitution of plant-based oils for mineral oil.
• Replacement of toxic polymers by soy.
• Orange citrus has been used to replace some solvents.
• Slicking agents have been replaced by palm oil.
• Diesel fuel has been phased out as a solvent. It contains benzene, a known carcinogen. Diesel has voluntarily been withdrawn by fracturing companies. It has been replaced with mineral oil, a less toxic solvent.
