Mitigation of CO2 is a very popular research currently, it is ultimately beneficial to find new ways that are sustainable, low cost and gas emission friendly. Therefore, with biochar’s characteristics and properties it has great potential to be used as a CO2 capture and storage media. The objectives of reducing palm waste by using the low-cost, sustainable method for reducing and storing CO2, characterize the DPL biochar through FTIR, XRD, SEM, EDX, and then evaluate the efficiency of the date palm leaf waste biochar in adsorbing CO2 through the Gas–Solid analyzer technology. Date palm leaf was set in pyrolysis process at 500°C peak at a 10°C per min rate for 5 h. The peaks of maximum intensity are approximately 1000 to 1500 cm −1; two peaks are approximately 1110 and 1600 cm-1 as the transition rises when the peaks are wider and shorter. Carbonyls, Alkenes, Alkynes, and others were found in feature groups, but the maximum area with O-H and C-H bonds and vibration picks is reduced and nearly non-existent. Biochar showed porous and heterogeneous structures with various magnifications, which give a greater amount of surface for adsorption. XRD analysis indicated that cellulose could progressively be decreased. The weighing of each component was 83.56% for Carbon, 12.43% for Oxygen, 1.12% for Potassium, 1.64% for Calcium, 0,83% for Phosphorus and 0.4% for Magnesium. The presence of these metals gives a strong CO2 attraction. The area value was found to have been approximately 3.117, reflecting the total CO2 obtained by the date palm leaf biochar. This shows that 300 gr of DPL biochar have been consumed by just one third of CO2. Date palm leaf of biochar’s shows a carbon dioxide adsorption efficiency of 20% and measured CO2 adsorption per g of biochar DPL of 0.017 g at 500 °C pyrolysis temperature and conditions set.
