COMMISSION DECISION

of 10 June 2010

on guidelines for the calculation of land carbon stocks for the purpose of Annex V to Directive 2009/28/EC

(notified under document C(2010) 3751)

(2010/335/EU)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive 2009/28/EC of the European Parliament and of the Council of 23 April 2009 on the promotion of the use of energy from renewable sources and amending and subsequently repealing Directives 2001/77/EC and 2003/30/EC (1), and in particular Annex V, part C, point 10 thereof,

Whereas:

(1)

Directive 2009/28/EC lays down rules for calculating the greenhouse gas impact of biofuels, bioliquids and their fossil fuel comparators, which take into account emissions from carbon stock changes caused by land use change. Directive 98/70/EC of the European Parliament and of the Council of 13 October 1998 relating to the quality of petrol and diesel fuels and amending Council Directive 93/12/EEC (2) includes corresponding rules as far as biofuels are concerned.

(2)

The Commission should draw its guidelines for the calculation of land carbon stocks on the 2006 Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories. Those Guidelines were intended for national greenhouse gas inventories and are not expressed in a form that is readily applicable by economic operators. It is therefore appropriate, where IPCC Guidelines for National Greenhouse Gas Inventories lack the necessary information for purposes of biofuel and bioliquid production or where such information is not accessible, to draw on other scientific sources of data.

(3)

For the calculation of the carbon stocks in soil organic matter it is appropriate to take into account climate, soil type, land cover, land management and input. For mineral soils, the IPCC Tier 1 methodology for soil organic carbon is an appropriate method to use for this purpose as it covers the global level. For organic soils, the IPCC methodology addresses in particular carbon loss following soil drainage and does this only through annual losses. As soil drainage normally results in high carbon stock loss that cannot be compensated by the greenhouse gas saving of biofuels or bioliquids and as drainage of peatland soil is prohibited by the sustainability criteria laid down by Directive 2009/28/EC, it suffices to lay down general rules for determining soil organic carbon or carbon losses in organic soils.

(4)

For the calculation of carbon stock in living biomass and dead organic matter a low complexity approach corresponding to IPCC Tier 1 methodology for vegetation should be an appropriate method. In accordance with that methodology it is reasonable to assume that all carbon stock in living biomass and dead organic matter is lost from the land upon conversion. Dead organic matter is usually of low significance in land conversion for the establishment of crops for the production of biofuels and bioliquids, but should be taken into account at least for closed forests.

(5)

In calculating the greenhouse gas impact of land conversion, economic operators should be able to use actual values for the carbon stocks associated with the reference land use and the land use after conversion. They should also be able to use standard values and it is appropriate for these guidelines to provide them. It is not necessary, however, to provide standard values for improbable combinations of climate and soil type.

(6)

Annex V to Directive 2009/28/EC sets out the method for calculating greenhouse gas impacts and contains rules for the calculation of annualised emissions of carbon stock changes from land use changes. The guidelines annexed to this Decision establish rules for the calculation of land carbon stocks, completing the rules laid down in the Annex V,

HAS ADOPTED THIS DECISION:

Article 1

The guidelines for the calculation of land carbon stocks for the purpose of Annex V to Directive 2009/28/EC are set out in the Annex to this Decision.

1.   INTRODUCTION

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.   CONSISTENT REPRESENTATION OF LAND CARBON STOCKS

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.   CALCULATION OF CARBON STOCKS

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

CSi = (SOC + CVEG ) × A

where:

CSI= the carbon stock per unit area associated with the land use i (measured as mass of carbon per unit area, including both soil and vegetation);

SOC= soil organic carbon (measured as mass of carbon per hectare), calculated in accordance with point 4;

CVEG= above 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;

A= factor scaling to the area concerned (measured as hectares per unit area).

4.   SOIL ORGANIC CARBON STOCK

4.1.   Mineral soils

For the calculation of SOC the following rule may be used:

SOC = SOCST  × FLU  × FMG  × FI

where:

SOC= soil organic carbon (measured as mass of carbon per hectare);

SOCST= standard soil organic carbon in the 0-30 centimetre topsoil layer (measured as mass of carbon per hectare);

FLU= land use factor reflecting the difference in soil organic carbon associated with the type of land use compared to the standard soil organic carbon;

FMG= management factor reflecting the difference in soil organic carbon associated with the principle management practice compared to the standard soil organic carbon;

FI= input 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.   Organic soils (histosols)

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.   ABOVE AND BELOW GROUND VEGETATION CARBON STOCK

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:

CVEG= above and below ground vegetation carbon stock (measured as mass of carbon per hectare);

CBM= above and below ground carbon stock in living biomass (measured as mass of carbon per hectare), calculated in accordance with point 5.1;

CDOM= above 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.   Living biomass

For the calculation of CBM the following rule shall apply:

CBM = CAGB  + CBGB

where:

CBM= above and below ground carbon stock in living biomass (measured as mass of carbon per hectare);

CAGB= above ground carbon stock in living biomass (measured as mass of carbon per hectare), calculated in accordance with point 5.1.1;

CBGB= below ground carbon stock in living biomass (measured as mass of carbon per hectare), calculated in accordance with point 5.1.2.

5.1.1.   Above ground living biomass

For the calculation of CAGB the following rule shall apply:

CAGB = BAGB  × CFB

where:

CAGB= above ground carbon stock in living biomass (measured as mass of carbon per hectare);

BAGB= weight of above ground living biomass (measured as mass of dry matter per hectare);

CFB= carbon 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.   Below ground living biomass

For the calculation of CBGB one of the following two rules shall be used:

(1)

CBGB = BBGB  × CFB

where:

CBGB= below ground carbon stock in living biomass (measured as mass of carbon per hectare);

BBGB= weight of below ground living biomass (measured as mass of dry matter per hectare);

CFB= carbon 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:

CBGB= below ground carbon stock in living biomass (measured as mass of carbon per hectare);

CAGB= above ground carbon stock in living biomass (measured as mass of carbon per hectare);

R= ratio 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.   Dead organic matter

For the calculation of CDOM the following rule shall apply:

CDOM = CDW  + CLI

where:

CDOM= above and below ground carbon stock in dead organic matter (measured as mass of carbon per hectare);

CDW= carbon stock in dead wood pool (measured as mass of carbon per hectare), calculated in accordance with point 5.2.1;

CLI= carbon stock in litter (measured as mass of carbon per hectare), calculated in accordance with point 5.2.2.

5.2.1.   Carbon stock in dead wood pool

For the calculation of CDW the following rule shall apply:

CDW = DOMDW  × CFDW

where:

CDW= carbon stock in dead wood pool (measured as mass of carbon per hectare);

DOMDW= weight of dead wood pool (measured as mass of dry matter per hectare);

CFDW= carbon 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.   Carbon stock in litter

For the calculation of CLI the following rule shall apply:

CLI = DOMLI  × CFLI

where:

CLI= carbon stock in litter (measured as mass of carbon per hectare);

DOMLI= weight of litter (measured as mass of dry matter per hectare);

CFLI= carbon 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.

6.   STANDARD SOIL CARBON STOCK IN MINERAL SOILS

A value for SOCST shall be selected from table 1, based on the appropriate climate region and soil type of the area concerned as set out in points 6.1 and 6.2.

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

Table 3

Guidance on management and input for cropland and perennial crops

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.

Table 6

Guidance on management and input for grassland

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).

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.
