This study examines the potential of light-transmitting concrete (LTC) in reducing CO₂ emissions by using PMMA fibers and rods of different diameters and contents. Optical tests determined the light transmission coefficient of LTC samples to analyze CO₂ reduction efficiency per 1 m² of LTC. Results show that higher PMMA content in concrete improves light transmission, boosting energy savings and reduction of CO₂ emissions. Large-diameter PMMA rods are more efficient than small-diameter fibers. With an average annual illuminance of 50,000 lux, 1 m² of LTC containing 30% PMMA rods can reduce CO₂ emissions by 80 kg/year, nearly 10 times more effective than LTC with PMMA fibers under 1.5 mm in diameter and content below 8%. Effectiveness varies with geographic location and panel orientation relative to natural light.
