In the 2018 Impact report, page 68 (GRI) states a list of 'SCOPE 3 EMISSIONS – NOT RELEVANT/NOT YET CALCULATED'.
Therefore an accurate scope 3 total for 2018 could not be calculated.
Found in Nike 2018 Impact Report, page 46, 'Scope 3 Emissions (metric tonnes CO2e)' table.
(Calculation: 573,890+74,017+1,138,282+205,000+103,000+693,518 = 2,787,707)
