Abstract: Global warming mitigation via terrestrial albedo increase has been widely investigated in literature; the proposed methodologies relate CO 2 compensation to albedo increase generally via the concept of Radiative Forcing ( RF ). However, literature methods calculate RF by averaged input data, without considering RF variation due to many local and temporal phenomena. For instance, an average value of compensated effect of albedo change (Δ α = 0.01) is 3 kg CO 2eq /m 2 , which has been introduced no matter the position and climatic condition of the site. In our study, we propose a novel procedure to measure RF continuous time history by means of ground measurements, astronomical equations, and satellite calibration. The procedure is called RF -meter. In this way, a more accurate assessment of compensated CO 2 may be achieved. A test facility is also designed and proposed to double check the procedure, and preliminary results are reported in order to show and test the calibration procedure. It is expected that albedo-increased surfaces as well as cool roofs and/or other technical solutions will be eligible to obtain Emission Credits (EC). The proposed procedure will aid in the assignment of EC to High-Albedo Solutions (HAS), as it could represent an objective and accurate method to relate the albedo increase to a corresponding CO 2 offset.
