ANNEX
1. 
These guidelines establish the rules for the calculation of land carbon stocks, both for the reference land use (CSR, as defined in point 7 of Annex V to Directive 2009/28/EC) and the actual land use (CSA, as defined in point 7 of Annex V to Directive 2009/28/EC).

In point 2 rules are provided in order that land carbon stocks are consistently determined. Point 3 provides the general rule for the calculation of carbon stocks, which consist of two components: soil organic carbon and carbon stock in the above and below ground vegetation.

Point 4 provides detailed rules for determining the soil organic carbon stock. For mineral soils it provides the option of following a method that allows the use of values provided for in the guidelines, while the option of using alternative methods is also provided for. For organic soils methods are described, but the guidelines do not contain values for determining soil organic carbon stock in organic soils.

Point 5 provides detailed rules for carbon stock in vegetation, but is only relevant in the case the choice is made not to use values for above and below ground vegetation carbon stock provided in point 8 of the guidelines (the use of the values provided in point 8 is not obligatory and for certain cases it may not contain the appropriate values).

Point 6 provides the rules to select the appropriate values in case the choice is made to use the guidelines’ values related to soil organic carbon in mineral soils (these values are provided in points 6 and 7). In these rules reference is made to data layers on climate regions and soil type available through the online Transparency platform established by Directive 2009/28/EC. Those data layers are detailed layers underlying figures 1 and 2 below.

Point 8 provides values for carbon stock in the above and below ground vegetation and related parameters. Points 7 and 8 provide values for four different land use categories: cropland, perennial crops, grassland and forest land.

2. 
For determining the carbon stock per unit area associated with CSR and CSA the following rules shall apply:


((1)) the area for which the land carbon stocks are calculated shall for the entire area have similar:

((a)) biophysical conditions in terms of climate and soil type;
((b)) management history in terms of tillage;
((c)) input history in terms of carbon input to soil.
((2)) the carbon stock of the actual land use, CSA, shall be taken as:

— in the case of loss of carbon stock: the estimated equilibrium carbon stock that the land will reach in its new use,
— in the case of carbon stock accumulation: the estimated carbon stock after 20 years or when the crop reaches maturity, whichever the earlier.

3. 
For the calculation of CSR and CSA the following rule shall apply:

CSi = (SOC + CVEG) × A

where:

CSIthe carbon stock per unit area associated with the land use i (measured as mass of carbon per unit area, including both soil and vegetation);SOCsoil organic carbon (measured as mass of carbon per hectare), calculated in accordance with point 4;CVEGabove and below ground vegetation carbon stock (measured as mass of carbon per hectare), calculated in accordance with point 5 or selected from the appropriate values in point 8;Afactor scaling to the area concerned (measured as hectares per unit area).

4.  4.1. 
For the calculation of SOC the following rule may be used:

SOC = SOCST × FLU × FMG × FI

where:

SOCsoil organic carbon (measured as mass of carbon per hectare);SOCSTstandard soil organic carbon in the 0-30 centimetre topsoil layer (measured as mass of carbon per hectare);FLUland use factor reflecting the difference in soil organic carbon associated with the type of land use compared to the standard soil organic carbon;FMGmanagement factor reflecting the difference in soil organic carbon associated with the principle management practice compared to the standard soil organic carbon;FIinput factor reflecting the difference in soil organic carbon associated with different levels of carbon input to soil compared to the standard soil organic carbon.

For SOCST the appropriate values presented in point 6 shall apply.

For FLU, FMG and FI the appropriate values presented in point 7 shall apply.

As an alternative to using the above rule, other appropriate methods, including measurements, may be used to determine SOC. As far as such methods are not based on measurements, they shall take into account climate, soil type, land cover, land management and inputs.
 4.2. 
For determining SOC, appropriate methods shall be used. Such methods shall take into account the entire depth of the organic soil layer as well as climate, land cover and land management and input. Such methods may include measurements.

Where carbon stock affected by soil drainage is concerned, losses of carbon following drainage shall be taken into account by appropriate methods. Such methods may be based on annual losses of carbon following drainage.

5. 
Except where a value for CVEG set out in point 8 is used, for the calculation of CVEG the following rule shall apply:

CVEG = CBM + CDOM

where:

CVEGabove and below ground vegetation carbon stock (measured as mass of carbon per hectare);CBMabove and below ground carbon stock in living biomass (measured as mass of carbon per hectare), calculated in accordance with point 5.1;CDOMabove and below ground carbon stock in dead organic matter (measured as mass of carbon per hectare), calculated in accordance with point 5.2.

For CDOM the value of 0 may be used, except in the case of forest land — excluding forest plantations — having more than 30 % canopy cover.
 5.1. 
For the calculation of CBM the following rule shall apply:

CBM = CAGB + CBGB

where:

CBMabove and below ground carbon stock in living biomass (measured as mass of carbon per hectare);CAGBabove ground carbon stock in living biomass (measured as mass of carbon per hectare), calculated in accordance with point 5.1.1;CBGBbelow ground carbon stock in living biomass (measured as mass of carbon per hectare), calculated in accordance with point 5.1.2.
 5.1.1. 
For the calculation of CAGB the following rule shall apply:

CAGB = BAGB × CFB

where:

CAGBabove ground carbon stock in living biomass (measured as mass of carbon per hectare);BAGBweight of above ground living biomass (measured as mass of dry matter per hectare);CFBcarbon fraction of dry matter in living biomass (measured as mass of carbon per mass of dry matter).

For cropland, perennial crops and forest plantations the value for BAGB shall be the average weight of the above ground living biomass during the production cycle.

For CFB the value of 0,47 may be used.
 5.1.2. 
For the calculation of CBGB one of the following two rules shall be used:


((1)) CBGB = BBGB × CFB
where:
CBGBbelow ground carbon stock in living biomass (measured as mass of carbon per hectare);BBGBweight of below ground living biomass (measured as mass of dry matter per hectare);CFBcarbon fraction of dry matter in living biomass (measured as mass of carbon per mass of dry matter).
For cropland, perennial crops and forest plantations the value for BBGB shall be the average weight of the below ground living biomass during the production cycle.
For CFB the value of 0,47 may be used.
((2)) CBGB = CAGB × R
where:
CBGBbelow ground carbon stock in living biomass (measured as mass of carbon per hectare);CAGBabove ground carbon stock in living biomass (measured as mass of carbon per hectare);Rratio of below ground carbon stock in living biomass to above ground carbon stock in living biomass.
Appropriate values for R set out in point 8 may be used.
 5.2. 
For the calculation of CDOM the following rule shall apply:

CDOM = CDW + CLI

where:

CDOMabove and below ground carbon stock in dead organic matter (measured as mass of carbon per hectare);CDWcarbon stock in dead wood pool (measured as mass of carbon per hectare), calculated in accordance with point 5.2.1;CLIcarbon stock in litter (measured as mass of carbon per hectare), calculated in accordance with point 5.2.2.
 5.2.1. 
For the calculation of CDW the following rule shall apply:

CDW = DOMDW × CFDW

where:

CDWcarbon stock in dead wood pool (measured as mass of carbon per hectare);DOMDWweight of dead wood pool (measured as mass of dry matter per hectare);CFDWcarbon fraction of dry matter in dead wood pool (measured as mass of carbon per mass of dry matter).

For CFDW the value of 0,5 may be used.
 5.2.2. 
For the calculation of CLI the following rule shall apply:

CLI = DOMLI × CFLI

where:

CLIcarbon stock in litter (measured as mass of carbon per hectare);DOMLIweight of litter (measured as mass of dry matter per hectare);CFLIcarbon fraction of dry matter in litter (measured as mass of carbon per mass of dry matter).

For CFLI the value of 0,4 may be used.

Table 3 provides guidance for selecting appropriate values from Tables 2 and 4.


Management/Input Guidance
Full-tillage Substantial soil disturbance with full inversion and/or frequent (within year) tillage operations. At planting time, little (e.g. < 30 %) of the surface is covered by residues.
Reduced tillage Primary and/or secondary tillage but with reduced soil disturbance (usually shallow and without full soil inversion) and normally leaves surface with > 30 % coverage by residues at planting.
No till Direct seeding without primary tillage, with only minimal soil disturbance in the seeding zone. Herbicides are typically used for weed control.
Low Low residue return occurs when there is due to removal of residues (via collection or burning), frequent bare-fallowing, production of crops yielding low residues (e.g. vegetables, tobacco, cotton), no mineral fertilisation or nitrogen-fixing crops.
Medium Representative for annual cropping with cereals where all crop residues are returned to the field. If residues are removed then supplemental organic matter (e.g. manure) is added. Also requires mineral fertilisation or nitrogen-fixing crop in rotation.
High with manure Represents significantly higher carbon input over medium carbon input cropping systems due to an additional practice of regular addition of animal manure.
High without manure Represents significantly greater crop residue inputs over medium carbon input cropping systems due to additional practices, such as production of high residue yielding crops, use of green manures, cover crops, improved vegetated fallows, irrigation, frequent use of perennial grasses in annual crop rotations, but without manure applied (see row above).

Table 6 provides guidance for selecting appropriate values from Table 5.


Management/Input Guidance
Improved Represents grassland which is sustainably managed with moderate grazing pressure and that receive at least one improvement (e.g. fertilisation, species improvement, irrigation).
Nominally managed Represents non-degraded and sustainably managed grassland, but without significant management improvements.
Moderately degraded Represents overgrazed or moderately degraded grassland, with somewhat reduced productivity (relative to the native or nominally managed grassland) and receiving no management inputs.
Severely degraded Implies major long-term loss of productivity and vegetation cover, due to severe mechanical damage to the vegetation and/or severe soil erosion.
Medium Applies where no additional management inputs have been used.
High Applies to improved grassland where one or more additional management inputs/improvements have been used (beyond that is required to be classified as improved grassland).

Land use Guidance
Native forest(non-degraded) Represents native or long-term, non-degraded and sustainably managed forest.
Shifting cultivation Permanent shifting cultivation, where tropical forest or woodland is cleared for planting of annual crops for a short time (e.g. 3-5 years) period and then abandoned to regrowth.
Mature fallow Represents situations where the forest vegetation recovers to a mature or near mature state prior to being cleared again for cropland use.
Shortened fallow Represents situations where the forest vegetation recovery is not attained prior to reclearing.
