b'2018 Performance Data(continued) ENVIRONMENTThe Environment data presented in this report is for Kosmos operated assets only. Waste and air emissions are measured in tons, with greenhouse gas emissions measured in metric tons of COequivalent. The data represents 2drilling rigs as well as seismic and support vessels. In 2018, Kosmos drilled exploration wells offshore Senegal and Suriname, conducted seismic surveys offshore Equatorial Guinea and Western Sahara, and completed a geophysical and geotechnical study offshore Morocco.2018Equatorial Guinea Morocco Senegal Suriname Western SaharaWASTE (TONS)Hazardous 60.25 111.34 164.65 1,182.15 116.64Non-Hazardous 356.68 61.94 75.44 622.26 407.22TOTAL 416.93 173.28 240.09 1,804.41 523.86Recycled/Reused/Treated 37% 20% 42% 50% 24%AIR EMISSIONS (TONS)Carbon Dioxide (CO 2 ) 27,336.24 640.80 15,071.05 43,018.91 21,129.14Mono-Nitrogen Oxides (NO x )507.42 11.9 279.75 798.59 392.21Sulfur Dioxide (SO x ) 34.17 0.8 18.84 53.8 26.42Methane (CH 4 ) 1.54 0.04 0.85 2.47 1.19Volatile Organic Compounds (VOCS)17.1 0.4 9.42 26.96 13.21Greenhouse Gases (GHGS) 27,877.56 652.52 15,367.80 43,864.52 21,546.71OTHERFines and Penalties 0 0 0 0 0Freshwater Use (m3)1,260.00 225.00 5,987.80 16,300.00 352.00Hydrocarbon or Non-Aqueous0 0 0 0 0Drilling Fluid Spills2016 2017MauritaniaSenegalSuriname Mauritania Senegal Suriname Morocco Western Sahara So Tom & PrncipeWASTE (TONS)Hazardous 298.67 112.44 10.54 830.25 319.06 2.37 N/A N/A 144.13Non-Hazardous 296.80 114.11 82.90 412.65 135.96 6.56 N/A N/A 862.31TOTAL 595.47 226.55 93.44 1,242.90 455.02 8.93 N/A N/A 1,006.44Recycled/Reused/Treated54% 43% 10% 45% 62% 85% N/A N/A N/AAIR EMISSIONS (TONS)Carbon Dioxide (CO 2 ) 51,893.95 20,815.17 20,530.75 118,930.15 54,458.17 8,113.02 20,881.64 15,498.28 111,361.28Mono-Nitrogen Oxides (NO x )964.32 387.47 381.10 2,207.86 1,010.78 150.60 387.62 287.68 2,067.15Sulfur Dioxide (SO x ) 64.80 25.96 25.66 148.67 68.11 10.15 26.10 19.38 139.20Methane (CH 4 ) 2.88 1.13 11.55 6.63 2.99 0.46 1.18 0.87 6.27Volatile Organic Compounds (VOCS)32.50 13.00 12.83 74.23 33.67 5.06 13.06 9.69 69.60Greenhouse Gases (GHGS) 51,954.43 20,838.84 20,773.30 119,069.33 54,521.26 8,122.64 20,906.44 15,516.50 111,492.87OTHERFines and Penalties 0 0 0 0 0 0 0 0 0Freshwater Use (m3)1,728.00 3,082.00 3,744.00 26,799.25 6,159.20 N/A N/A N/A 7,012.00Hydrocarbon or Non-Aqueous0 0 0 0 0 0 0 0 0Drilling Fluid Spills64'
