The culminating effect of increasing greenhouse gasses on climate change has proven to be a significant scientific concern. Due to its increased concentration and long decay time, carbon dioxide is responsible for nearly half of the greenhouse effect. The main contributor responsible for carbon dioxide emissions comes from fossil fuels, which accounts for 75% of all anthropogenic carbon dioxide emissions. It would be impractical to halt the use of fossil fuels as they contribute to 86% of the entire world's energy and can be found in nearly every region of the globe. There in lies the urgency to determine a way to capture and/or utilize the carbon dioxide in the atmosphere. Alkyl and aryl phosphonates were evaluated in multiple fashions with the interest of attaching an amino group to each substituent of the phosphonates. The synthesis of bis(2-aminoethyl) phosphonate was attempted through the heat reaction, HCl method, modified HCl method, acetic acid method, and the base solution method, with partial success only in the acetic acid reaction using diphenyl phosphonate. Control carbamates were tested for carbon capture capabilities by testing a multitude of solvents with 2-aminoethanol at room temperature and 38 °C. Absolute and 95% ethanol solvents both resulted in captured carbon dioxide by 2-aminoethanol.
