(For comparison, official mineral-oil data of the Federal Office of Economics and Export Control (BAFA, 2023) [(BAFA2023)] are applied, too.) Data on the consumption of //biodiesel// is provided in NEB line 64 from 2004 onward. However, as this data appears to be rather inconsistent, the consumption of biofuels is calculated within TREMOD via the official annual blending rates. __Table 1: Primary fuel deliveries as listed in the National Energy Balance, in terajoules__ | ^ 1990 ^ 1995 ^ 2000 ^ 2005 ^ 2010 ^ 2015 ^ 2016 ^ 2017 ^ 2018 ^ 2019 ^ 2020 ^ 2021 ^ 2022 ^ | **NEB line 6 - Maritime Bunkers ('Hochseebunkerungen')** |||||||||||||| ^ Diesel | 23,336 | 20,426 | 21,542 | 18,342 | 22,340 | 43,254 | 42,198 | 9,822 | | | | | | ^ Light fuel oil (Heating oil) | NO ||||||| 26,958 | 31,266 | 30,087 | 22,684 | 30,118 | 31,551 | ^ Heavy fuel oil | 80,230 | 64,382 | 69,578 | 86,272 | 93,886 | 57,386 | 75,445 | 58,277 | 39,248 | 26,813 | 32,431 | 28,106 | 29,534 | ^ LNG1 | NO ||||| 22.0 | 64.4 | 58.8 | 197 | 153 | 276 | 293 | 513 | | **NEB line 64 - Coastal and Inland Navigation ('Küsten- und Binnenschifffahrt')** |||||||||||||| ^ Diesel oil | 27,716 | 23,562 | 11,864 | 19,842 | 18,370 | 15,894 | 14,529 | 14,907 | 14,813 | 14,660 | 14,029 | 12,003 | 9,819 | ^ LPG | //7.00// | //7.00// | //7.00// | 7.02 | 7.08 | 7.10 | 7.25 | 7.06 | 7.13 | 7.16 | 7.40 | 7.51 | 7.58 | ^ Gasoline | //272// | //272// | //272// | 274 | 261 | 265 | 265 | 266 | 262 | 265 | 269 | 273 | 275 | ^ Biogasoline2 | NO ||| 1.90 | 10.1 | 10.7 | 10.8 | 10.8 | 11.3 | 10.9 | 12.0 | 12.9 | 12.8 | | **TOTAL inland fuel deliveries** ^ 131,561 ^ 108,649 ^ 103,263 ^ 124,739 ^ 134,875 ^ 116,838 ^ 132,520 ^ 110,305 ^ 85,805 ^ 71,996 ^ 69,708 ^ 70,812 ^ 71,713 ^ data sources: fossil liquid fuels: NEB [(AGEB2023)]; 1LNG (as not yet included in NEB): BSH model [(DEICHNIK20023)], 2biogasoline: TREMOD [(KNOERR2023a)] \\ //italic numbers//: extrapolated backwards as data provided in NEB only as of 2003 As the statistical allocation of fuels delivered to the navigation (shipping) sector follows tax aspects, NEB line 6 ('International Maritime Bunkers') includes all fuel deliveries to IMO-registered ship involved in both national and international maritime activities. On the other hand, NEB line 64 ('Coastal and Inland Navigation') includes all fuel deliveries to ship involved in inland and non-IMO maritime navigation. __Table 2: Allocation of for subsector-specfic fuel deliveries data in the NEB__ ^ NEB line ^ including fuel deliveries to navigation sub-sectors... || | 6 - 'International Maritime Bunkers' | ...international maritime navigation / national maritime navigation (IMO) / national fishing (IMO) / military navigation (IMO) || | 64 - 'Coastal and Inland Navigation' | ...national inland navigation / national maritime navigation (non-IMO) / national fishing (non-IMO) / military navigation (non-IMO) || Therefore, the amounts of fuels listed in NEB lines 6 and 64 are broken down on several sub-sectors. Regarding all national maritime activities, taking place in National Maritime Navigation, national fishing, and military navigation, a country-specific approach allows for estimating tier3 fuel consumption data based on ship movement information (AIS signal) for IMO- and non-IMO ships. In contrast to this bottom-up approach, fuel consumption in both //international maritime navigation// and //national inland navigation// are calculated as tier1 estimates. The following equations and charts try to illustrate the way of deducing these tier1 activity data: **Estimating the tier1 activity data for International maritime navigation:** | AD1.A.3.d i = PADNEB line 6 - AD1.A.3.d ii (a) - IMO - AD1.A.4.c iii - IMO - AD1.A.5.b iii - IMO | with \\ * AD1.A.3.d i - tier1 activity data for International maritime navigation\\ * PADNEB line 6 - primary over-all fuel deliveries data from NEB line 6 - 'International Maritime Bunkers'\\ * AD1.A.3.d ii (a) - IMO - tier3 activity data for IMO-registered ships involved in national maritime navigation\\ * AD1.A.4.c iii - IMO - tier3 activity data for IMO-registered ships involved in national fishing\\ * AD1.A.5.b iii - IMO - tier3 activity data for IMO-registered ships involved in military navigation | **Estimating the tier1 activity data for National inland navigation:** | AD1.A.3.d ii (b) = PADNEB line 64 - AD1.A.3.d ii (a) - non-IMO - AD1.A.4.c iii - non-IMO - AD1.A.5.b iii - non-IMO\\ | with \\ * AD1.A.3.d ii (b) - tier1 activity data for National inland navigation\\ * PADNEB line 64 - primary over-all fuel deliveries data from NEB line 64 - 'Coastal and Inland Navigation'\\ * AD1.A.3.d ii (a) - non-IMO - tier3 activity data for non-IMO ships involved in national maritime navigation\\ * AD1.A.4.c iii -non-IMO - tier3 activity data for for non-IMO ships involved in national fishing\\ * AD1.A.5.b iii - non-IMO - tier3 activity data for for non-IMO ships involved in military navigation | __Table 3: Resulting breakdown of primary fuel deliveries onto the different navigation sub-sectors, in terajoules__ | ^ 1990 ^ 1995 ^ 2000 ^ 2005 ^ 2010 ^ 2015 ^ 2016 ^ 2017 ^ 2018 ^ 2019 ^ 2020 ^ 2021 ^ 2022 ^ | **TOTAL** ^ 131,561 ^ 108,649 ^ 103,263 ^ 124,739 ^ 134,875 ^ 116,838 ^ 132,520 ^ 110,305 ^ 85,805 ^ 71,996 ^ 69,708 ^ 70,812 ^ 71,713 ^ | | | | | | | | | | | | | | | | **1.A.3.d i - International maritime navigation** |||||||||||||| ^ Diesel oil | 13,162 | 13,096 | 13,709 | 11,546 | 16,273 | 33,836 | 32,424 | 27,370 | 16,000 | NO |||| ^ Light fuel oil | NO |||||||| 5,333 | 20,104 | 13,606 | 21,260 | 23,321 | ^ Heavy fuel oil | 76,942 | 62,066 | 67,080 | 84,127 | 91,992 | 57,278 | 75,408 | 58,196 | 38,986 | 26,418 | 32,053 | 27,713 | 29,297 | | **1.A.3.d ii (a) - National maritime navigation** |||||||||||||| ^ Diesel oil | 9,484 | 6,828 | 7,367 | 6,399 | 5,690 | 8,980 | 9,335 | 8,960 | 7,084 | NO |||| ^ Light fuel oil | NO |||||||| 2,361 | 9,497 | 8,329 | 8,475 | 7,879 | ^ Heavy fuel oil | 3,103 | 2,186 | 2,382 | 2,054 | 1,810 | 108 | 37,0 | 81,1 | 262 | 394 | 378 | 392 | 237 | ^ LNG | NO ||||| 22.0 | 64.4 | 58.8 | 197 | 153 | 276 | 293 | 513 | | **1.A.3.d ii (b) - National inland navigation** |||||||||||||| ^ Diesel oil | 27,716 | 23,562 | 11,864 | 19,842 | 18,370 | 15,894 | 14,529 | 14,907 | 14,813 | 14,660 | 14,029 | 12,003 | 9,819 | ^ Gasoline | 272 | 272 | 272 | 274 | 261 | 265 | 265 | 266 | 262 | 265 | 269 | 273 | 275 | ^ Biogasoline | | | | 1.90 | 10.1 | 10.7 | 10.8 | 10.8 | 11.3 | 10.9 | 12.0 | 12.9 | 12.8 | ^ LPG | 7.00 | 7.00 | 7.00 | 7.02 | 7.08 | 7.10 | 7.25 | 7.06 | 7.13 | 7.16 | 7.40 | 7.51 | 7.58 | | **[[sector:energy:fuel_combustion:small_combustion:mobile_small_combustion:fishing| 1.A.4.c iii - National Fishing ]]** |||||||||||||| ^ Diesel oil | 305 | 240 | 238 | 226 | 227 | 284 | 298 | 293 | 267 | NO |||| ^ Light fuel oil | NO |||||||| 88.9 | 322 | 359 | 265 | 221 | ^ Heavy fuel oil | 33.3 | 26.0 | 26.0 | 24.4 | 24.5 | NO |||||||| | **[[sector:energy:fuel_combustion:other_including_military:military_transport:military_navigation| 1.A.5.b iii - Military Navigation ]] ** |||||||||||||| ^ Diesel oil | 380 | 263 | 228 | 171 | 150 | 154 | 141 | 156 | 99.5 | NO |||| ^ Light fuel oil | NO |||||||| 33.2 | 164 | 390 | 118 | 131 | ^ Heavy fuel oil | 152 | 104 | 90.4 | 67.4 | 59.0 | NO |||||||| ==== Emission factors ==== Annual country-specific emission factors have been developed within the underlying models maintained at the ifeu Institute for Energy and Environmental Research (Knörr et al.
