Σ (Substance X % x GWP) + (Substance Y % x GWP) + … (Substance N % x GWP) where % is the contribution by weight with a weight tolerance of +/- 1 %. For example: applying the formula to a theoretical blend of gases consisting of 23 % HFC-32; 25 % HFC-125 and 52 % HFC-134a; Σ (23 % x 550) + (25 % x 3400) + (52 % x 1300) → Total GWP = 1652,5
