Monitoring and Reporting of Greenhouse Gas Emissions Pursuant to Directive 200387EC of the European Parliament and of the Council Text with EEA Relevance Regulation
Article 1: Subject matter
Article 2: Scope
It shall apply to emissions and activity data occurring from 1 January 2013.
Article 3: Definitions
Article 4: General obligation
Article 5: Completeness
Operators and aircraft operators shall apply appropriate measures to prevent any data gaps within the reporting period.
Article 6: Consistency, comparability and transparency
Article 7: Accuracy
They shall identify and reduce any source of inaccuracies as far as possible.
They shall exercise due diligence to ensure that the calculation and measurement of emissions exhibit the highest achievable accuracy.
Article 8: Integrity of methodology
Reported emission data and related disclosures shall be free from material misstatement, avoid bias in the selection and presentation of information, and provide a credible and balanced account of an installation’s or aircraft operator’s emissions.
In selecting a monitoring methodology, the improvements from greater accuracy shall be balanced against the additional costs. Monitoring and reporting of emissions shall aim for the highest achievable accuracy, unless this is technically not feasible or incurs unreasonable costs.
Article 9: Continuous improvement
Article 10: Coordination
Article 11: General obligation
The monitoring plan shall be supplemented by written procedures which the operator or aircraft operator establishes, documents, implements and maintains for activities under the monitoring plan, as appropriate.
Article 12: Content and submission of the monitoring plan
The monitoring plan shall consist of a detailed, complete and transparent documentation of the monitoring methodology of a specific installation or aircraft operator and shall contain at least the elements laid down in Annex I.
Together with the monitoring plan, the operator or aircraft operator shall submit all of the following supporting documents:
The operator or the aircraft operator shall summarise the procedures in the monitoring plan providing the following information:
Article 13: Standardised and simplified monitoring plans
For that purpose, Member States may publish templates for those monitoring plans, including the description of data flow and control procedures referred to in Article 57 and Article 58, based on the templates and guidelines published by the Commission.
Member States may require the operator or aircraft operator to carry out the risk assessment pursuant to the previous subparagraph itself, where appropriate.
Article 14: Modifications of the monitoring plan
Article 15: Approval of modifications of the monitoring plan
However, the competent authority may allow the operator or aircraft operator to notify, by 31 December of the same year, modifications of the monitoring plan that are not significant within the meaning of paragraph 3.
Where the competent authority considers a modification not significant, it shall inform the operator or aircraft operator thereof without undue delay.
Article 16: Implementation and recordkeeping of modifications
In case of doubt, the operator or aircraft operator shall carry out all monitoring and reporting, and in the interim documentation, in parallel, using both the modified and the original monitoring plan.
Article 17: Technical feasibility
Article 18: Unreasonable costs
The competent authority shall consider costs unreasonable where the cost estimation exceeds the benefit. To that end, the benefit shall be calculated by multiplying an improvement factor with a reference price of EUR 20 per allowance and costs shall include an appropriate depreciation period based on the economic lifetime of the equipment.
In the absence of the average annual emissions caused by that source stream over the three most recent years, the operator or aircraft operator shall provide a conservative estimate of the annual average emissions, with the exclusion of CO 2 stemming from biomass and before subtraction of transferred CO 2 . For measuring instruments under national legal metrological control, the uncertainty currently achieved may be substituted by the maximum permissible error in service allowed by the relevant national legislation. 2 2
Article 19: Categorisation of installations and source streams
Article 20: Monitoring boundaries
Within those boundaries, the operator shall include all relevant greenhouse gas emissions from all emission sources and source streams belonging to activities carried out at the installation and listed in Annex I to Directive 2003/87, as well as from activities and greenhouse gases included by a Member State pursuant to Article 24 of Directive 2003/87.
The operator shall also include emissions from regular operations and abnormal events including start-up and shut-down and emergency situations over the reporting period, with the exception of emissions from mobile machinery for transportation purposes.
The competent authority may allow the exclusion of a leakage emission source from the monitoring and reporting process, once corrective measures pursuant to Article 16 of GSCDD have been taken and emissions or release into the water column from that leakage can no longer be detected.
Article 21: Choice of the monitoring methodology
A calculation-based methodology shall consist in determining emissions from source streams based on activity data obtained by means of measurement systems and additional parameters from laboratory analyses or default values. The calculation-based methodology may be implemented through the standard methodology set out in Article 24 or the mass balance methodology set out in Article 25.
A measurement-based methodology shall consist in determining emissions from emission sources by means of continuous measurement of the concentration of the relevant greenhouse gas in the flue gas and of the flue gas flow, including the monitoring of CO 2 transfers between installations where the CO 2 concentration and the flow of the transferred gas are measured. 2 2
Where the calculation-based methodology is applied, the operator shall for each source stream define, in the monitoring plan, whether the standard methodology or the mass balance methodology is used, including the relevant tiers in accordance with Annex II.
Article 22: Monitoring methodology not based on tiers
Article 23: Temporary changes to the monitoring methodology
The operator shall take all necessary measures to allow the prompt restoration of the tier in the monitoring plan as approved by the competent authority.
Article 24: Calculation of emissions under the standard methodology
The competent authority may allow the use of emission factors for fuels, expressed as t CO 2 /t or t CO 2 /Nm 3 . In that case, the operator shall determine combustion emissions by multiplying the activity data related to the amount of fuel combusted, expressed as tonnes or normal cubic metres, with the corresponding emission factor and the corresponding oxidation factor. 2 2 3
Article 25: Calculation of emissions under the mass balance methodology
Article 26: Applicable tiers
The competent authority may, for a transitional period of up to three years, allow an operator to apply lower tiers than those referred to in the second subparagraph, with a minimum of tier 1, provided that both of the following conditions are met:
Article 27: Determination of activity data
Where it is technically not feasible or would incur unreasonable costs to determine quantities in stock by direct measurement, the operator may estimate those quantities based on one of the following:
Article 28: Measurement systems under the operator’s control
The assessment shall comprise the specified uncertainty of the applied measuring instruments, uncertainty associated with the calibration, and any additional uncertainty connected to how the measuring instruments are used in practice. Uncertainty related to stock changes shall be included in the uncertainty assessment where the storage facilities are capable of containing at least 5 % of the annual used quantity of the fuel or material considered. When carrying out the assessment, the operator shall take into account the fact that the stated values used to define tier uncertainty thresholds in Annex II refer to the uncertainty over the full reporting period.
The operator may simplify the uncertainty assessment by assuming that the maximum permissible errors specified for the measuring instrument in service, or where lower, the uncertainty obtained by calibration, multiplied by a conservative adjustment factor for taking into account the effect of uncertainty in service, is to be regarded as the uncertainty over the whole reporting period as required by the tier definitions in Annex II, provided that measuring instruments are installed in an environment appropriate for their use specifications.
For that purpose, the maximum permissible error in service allowed by the relevant national legislation on legal metrological control for the relevant measuring task may be used as the uncertainty value without providing further evidence.
Article 29: Measurement systems outside the operator’s own control
To that end, the operator may revert to one of the following data sources:
To that end, the maximum permissible error in service allowed by relevant legislation for national legal metrological control for the relevant commercial transaction may be used as uncertainty without providing further evidence.
Where the applicable requirements under national legal metrological control are less stringent than the applicable tier pursuant to Article 26, the operator shall obtain evidence on the applicable uncertainty from the trade partner responsible for the measurement system.
Article 30: Determination of calculation factors
Where such an approach incurs unreasonable costs, or where higher accuracy can be achieved, the operator may consistently report activity data and calculation factors referring to the state in which laboratory analyses are carried out.
Article 31: Default values for calculation factors
Where the default values change on an annual basis, the operator shall specify the authoritative applicable source of that value in the monitoring plan.
Article 32: Calculation factors based on analyses
Where such standards are not available, the methods shall be based on suitable ISO standards or national standards. Where no applicable published standards exist, suitable draft standards, industry best practice guidelines or other scientifically proven methodologies shall be used, limiting sampling and measurement bias.
For the determination of a specific parameter the operator shall use the results of all analyses made with regards to that parameter.
Article 33: Sampling plan
The operator shall ensure that the derived samples are representative for the relevant batch or delivery period and free of bias. Relevant elements of the sampling plan shall be agreed with the laboratory carrying out the analysis for the respective fuel or material, and evidence of that agreement shall be included in the plan. The operator shall make the plan available for the purposes of verification pursuant to Regulation 2012/600.
Article 34: Use of laboratories
With respect to quality management, the operator shall produce an accredited certification of the laboratory in conformity with EN ISO/IEC 9001, or other certified quality management systems that cover the laboratory. In the absence of such certified quality management systems, the operator shall provide other appropriate evidence that the laboratory is capable of managing its personnel, procedures, documents and tasks in a reliable manner.
With respect to technical competence, the operator shall provide evidence that the laboratory is competent and able to generate technically valid results using the relevant analytical procedures. Such evidence shall cover at least the following elements:
Article 35: Frequencies for analyses
Article 36: Emission factors for CO2
The competent authority may allow the operator to use an emission factor for a fuel expressed as t CO 2 /t or t CO 2 /Nm 3 for combustion emissions, where the use of an emission factor expressed as t CO 2 /TJ incurs unreasonable costs or where at least equivalent accuracy of the calculated emissions can be achieved by using such an emission factor. 2 2 3 2
Article 37: Oxidation and conversion factors
However, the competent authority may require operators to always use tier 1.
Article 38: Biomass source streams
The emission factor of a mixed fuel or material shall be calculated and reported as the preliminary emission factor determined in accordance with Article 30 multiplied by the fossil fraction of the fuel or material.
Article 39: Determination of biomass and fossil fraction
In the absence of such standard factors and values, the operator shall either assume the absence of a biomass share or submit an estimation method to determine the biomass fraction to the competent authority for approval. For fuels or materials originating from a production process with defined and traceable input streams, the operator may base such estimation on a mass balance of fossil and biomass carbon entering and leaving the process.
Article 40: Use of the measurement-based monitoring methodology
In addition, the operator may use measurement-based methodologies for CO 2 emission sources where it can provide evidence that for each emission source the tiers required in accordance with Article 41 are complied with. 2
Article 41: Tier requirements
Article 42: Measurement standards and laboratories
Where such standards are not available, the methods shall be based on suitable ISO standards, standards published by the Commission or national standards. Where no applicable published standards exist, suitable draft standards, industry best practice guidelines or other scientifically proven methodologies shall be used, limiting sampling and measurement bias.
The operator shall consider all relevant aspects of the continuous measurement system, including the location of the equipment, calibration, measurement, quality assurance and quality control.
Where the laboratory does not have such accreditation, the operator shall ensure that equivalent requirements of Article 34(2) and (3) are met.
Article 43: Determination of emissions
In the case of CO 2 emissions, the operator shall determine annual emission on the basis of equation 1 in Annex VIII. CO emitted to the atmosphere shall be treated as the molar equivalent amount of CO 2 . 2 2
In the case of nitrous oxide (N 2 O), the operator shall determine annual emissions on the basis of the equation in subsection B.1 of section 16 of Annex IV. 2
Article 44: Data aggregation
Where an operator can generate data for shorter reference periods without additional cost, he shall use those periods for the determination of the annual emissions in accordance with Article 43(1).
Article 45: Missing data
Where the reporting period is not applicable for determining such substitution values due to significant technical changes at the installation, the operator shall agree with the competent authority a representative timeframe for determining the average and standard deviation, where possible with the duration of one year.
Article 46: Corroborating with calculation of emissions
The use of tier methodologies shall not be required.
Article 47: Installations with low emissions
The first subparagraph shall not apply to installations carrying out activities for which N 2 O is included pursuant to Annex I to Directive 2003/87. 2
The operator shall, without undue delay, submit a significant modification of the monitoring plan within the meaning of point (b) of Article 15(3), to the competent authority for approval.
However, the competent authority shall allow that the operator continues simplified monitoring provided that that operator demonstrates to the satisfaction of the competent authority that the threshold referred to in paragraph 2 has not already been exceeded within the past five reporting periods and will not be exceeded again from the following reporting period onwards.
Article 48: Inherent CO2
However, where inherent CO 2 is emitted, or transferred out of the installation to entities not covered by that Directive, it shall be counted as emissions of the installation where it originates. 2
Where the quantities of transferred and received inherent CO 2 are not identical, the arithmetic average of both measured values shall be used in both the transferring and receiving installations’ emission reports, where the deviation between the values can be explained by the uncertainty of the measurement systems. In such case, the emission report shall refer to the alignment of that value. 2
Where the deviation between the values cannot be explained by the approved uncertainty range of the measurement systems, the operators of the transferring and receiving installations shall align the values by applying conservative adjustments approved by the competent authority.
Article 49: Transferred CO2
The first subparagraph shall also apply to the receiving installation with respect to the transferring installation’s installation identification code.
However, the operator may apply the next lower tier provided that it establishes that applying tier 4 as defined in section 1 of Annex VIII is technically not feasible or incurs unreasonable costs.
Article 50: General provisions
To that end, the aircraft operator shall attribute all flights to the calendar year according to the time of departure measured in Coordinated Universal Time.
Article 51: Submission of monitoring plans
By way of derogation from the first subparagraph, an aircraft operator that performs an aviation activity covered by Annex I to Directive 2003/87 for the first time that could not be foreseen four months in advance of the activity, shall submit a monitoring plan to the competent authority without undue delay, but no later than six weeks after performance of that activity. The aircraft operator shall provide adequate justification to the competent authority why a monitoring plan could not be submitted four months in advance of the activity.
Where the administering Member State referred to in Article 18 a of Directive 2003/87 is not known in advance, the aircraft operator shall without undue delay submit the monitoring plan when information on the competent authority of the administering Member State becomes available.
Article 52: Monitoring methodology for emissions from aviation activities
However, aircraft operators having reported average annual emissions over the trading period immediately preceding the current trading period, which were equal to or less than 50 000 tonnes of fossil CO 2 may apply as a minimum tier 1 as defined in section 2 of Annex III. All aircraft operators may apply as a minimum tier 1 as defined in section 2 of Annex III for source streams jointly corresponding to less than 5 000 tonnes of fossil CO 2 per year or less than 10 %, up to a maximum contribution of 100 000 tonnes of fossil CO 2 per year, whichever is highest in terms of absolute value. Where, for the purposes of this subparagraph reported emissions are not available or no longer applicable, the aircraft operator may use a conservative estimate or projection to determine the average annual emissions. 2 2 2
In cases for which actual density values are not available, a standard density factor of 0,8 kg/litre shall be applied upon approval by the competent authority.
For reporting purposes, that approach shall be considered as tier 1. For fuels not listed in that table, the aircraft operator shall determine the emission factor in accordance with Article 32, considered as tier 2. For such fuels, the net calorific value shall be determined and reported as a memo-item.
Article 53: Specific provisions for biomass
Notwithstanding Article 39(2), the competent authority shall allow the use of a methodology uniformly applicable in all Member States for the determination of the biomass fraction, as appropriate.
Under that methodology, the biomass fraction, net calorific value and emission factor or carbon content of the fuel used in an EU ETS aviation activity listed in Annex I to Directive 2003/87/EC shall be determined using fuel purchase records.
The methodology shall be based on the guidelines provided by the Commission to facilitate its consistent application in all Member States.
The use of biofuels for aviation shall be assessed in accordance with Article 18 of Directive 2009/28/EC.
Article 54: Small emitters
The applicable tools may only be used if they are approved by the Commission including the application of correction factors to compensate for any inaccuracies in the modelling methods.
The aircraft operator shall, without undue delay, submit a significant modification of the monitoring plan within the meaning of point (vi) of Article 15(4) (a) to the competent authority for approval.
However, the competent authority shall allow that the aircraft operator continues to use a tool referred to in paragraph 2 provided that that aircraft operator demonstrates to the satisfaction of the competent authority that the thresholds referred to in paragraph 1 have not already been exceeded within the past five reporting periods and will not be exceeded again from the following reporting period onwards.

Aircraft operators not required to have a mass and balance documentation shall propose in the monitoring plan a suitable methodology for determining the mass of freight and mail, while excluding the tare weight of all pallets and containers that are not payload and the service weight.
Article 57: Data flow activities
Where the aircraft operator intends to apply for an allocation of allowances free of charge pursuant to Articles 3 e or 3 f of Directive 200 3 /87/EC, the first subparagraph shall also apply to the monitoring and reporting of tonne-kilometre data.
Article 58: Control system
Whenever the control system is found to be ineffective or not commensurate with the risks identified, the operator or aircraft operator shall seek to improve the control system and update the monitoring plan or the underlying written procedures for data flow activities, risk assessments and control activities as appropriate.
Article 59: Quality assurance
Where components of the measuring systems cannot be calibrated, the operator or aircraft operator shall identify those in the monitoring plan and propose alternative control activities.
When the equipment is found not to comply with required performance, the operator or aircraft operator shall promptly take necessary corrective action.
Where such quality assurance requires emission limit values (ELVs) as necessary parameters for the basis of calibration and performance checks, the annual average hourly concentration of the greenhouse gas shall be used as a substitute for such ELVs. Where the operator finds a non-compliance with the quality assurance requirements, including that recalibration has to be performed, it shall report that circumstance to the competent authority and take corrective action without undue delay.
Article 60: Quality assurance of information technology
The control of the information technology system shall include access control, control of back up, recovery, continuity planning and security.
Article 61: Segregation of duties
The operator or aircraft operator shall manage the necessary competencies for the responsibilities involved, including the appropriate assignment of responsibilities, training, and performance reviews.

Article 63: Corrections and corrective action
Article 64: Out-sourced processes
Article 65: Treatment of data gaps
Where the operator has not laid down the estimation method in a written procedure, it shall establish such written procedure and submit to the competent authority an appropriate modification of the monitoring plan in accordance with Article 15 for approval.
Where surrogate data cannot be determined in accordance with the first subparagraph of this paragraph, the emissions for that flight or those flights may be estimated by the aircraft operator from the fuel consumption determined by using a tool referred to in Article 54(2).
Article 66: Records and documentation
The documented and archived monitoring data shall allow for the verification of the annual emissions report or tonne-kilometre data in accordance with Regulation 2012/600. Data reported by the operator or aircraft operator contained in an electronic reporting and data management system set up by the competent authority may be considered to be retained by the operator or aircraft operator, if they can access those data.
The operator or aircraft operator shall, upon request, make those documents available to the competent authority as well as to the verifier verifying the emissions report or tonne-kilometre data report in accordance with Regulation 2012/600.
Article 67: Timing and obligations for reporting
However, competent authorities may require operators or aircraft operators to submit the verified annual emission report earlier than by 31 March, but by 28 February at the earliest.
Article 68: Force majeure
The Commission and the Member States shall use those data for the purposes of Article 3 e(3) and (4) of Directive 2003/87.
The aircraft operator shall, without undue delay, submit the verified data to the competent authority.
The competent authority concerned shall reduce and publish the revised allocation of free allowances for the aircraft operator pursuant to Article 3 e(4) of Directive 2003/87 as appropriate. The relevant allocation shall not be increased. Where applicable, the aircraft operator shall return any excess allowances received pursuant to Article 3 e(5) of that Directive.
Article 69: Reporting on improvements to the monitoring methodology
An operator of an installation shall submit to the competent authority for approval a report containing the information referred to in paragraph 2 or 3, where appropriate, by the following deadlines:
However, where evidence is found that measures needed for reaching those tiers have become technically feasible and do not any more incur unreasonable costs, the operator shall notify the competent authority of appropriate modifications of the monitoring plan in accordance with Article 15, and submit proposals for implementing the related measures and its timing.
However, where evidence is found that measures needed for reaching at least tier 1 for those source streams have become technically feasible and do not any more incur unreasonable costs, the operator shall notify the competent authority of appropriate modifications of the monitoring plan in accordance with Article 15 and submit proposals for implementing the related measures and its timing.
Where applicable, such report may be combined with the report referred to in paragraph 1 of this Article.
Where recommended improvements would not lead to an improvement of the monitoring methodology, the operator or aircraft operator shall provide a justification of why that is the case. Where the recommended improvements would incur unreasonable costs, the operator or aircraft operator shall provide evidence of the unreasonable nature of the costs.

The uncertainty thresholds shall be interpreted as maximum permissible uncertainties for the determination of source streams over a reporting period.
Where Table 1 does not include activities listed in Annex I to Directive 2003/87 and the mass balance is not applied, the operator shall use the tiers listed in Table 1 under ‘Combustion of fuels and fuels used as process input’ for those activities.
Table 1 Table 1
Tiers for activity data (maximum permissible uncertainty for each tier) Tiers for activity data (maximum permissible uncertainty for each tier)
Operators shall monitor CO 2 emissions from all types of combustion processes taking place under all activities as listed in Annex I to Directive 2003/87 or included in the Union Scheme under Article 24 of that Directive using the tier definitions laid down in this section. Where fuels are used as a process input, the same rules as for combustion emissions shall apply. Where fuels form part of a mass balance in accordance with Article 25(1) of this Regulation, the tier definitions for mass balances in section 3 of this Annex apply. 2
Process emissions from related exhaust gas scrubbing shall be monitored in accordance with subsection C of section 1 of Annex IV.

Calculation methodologies for the determination of GHGs in the aviation sector Calculation methodologies for the determination of GHGs in the aviation sector
Method A Method A
The operator shall use the following formula:
Actual fuel consumption for each flight [t] = Amount of fuel contained in aircraft tanks once fuel uplift for the flight is complete [t] – Amount of fuel contained in aircraft tanks once fuel uplift for subsequent flight is complete [t] + Fuel uplift for that subsequent flight [t]
Where there is no fuel uplift for the flight or subsequent flight, the amount of fuel contained in aircraft tanks shall be determined at block-off for the flight or subsequent flight. In the exceptional case that an aircraft performs activities other than a flight, including undergoing major maintenance involving the emptying of the tanks, after the flight for which fuel consumption is being monitored, the aircraft operator may substitute the quantity ‘Amount of fuel contained in aircraft tanks once fuel uplift for subsequent flight is complete + Fuel uplift for that subsequent flight’ with the ‘Amount of fuel remaining in tanks at the start of the subsequent activity of the aircraft’, as recorded by technical logs.
Method B Method B
The operator shall use the following formula:
Actual fuel consumption for each flight [t] = Amount of fuel remaining in aircraft tanks at block-on at the end of the previous flight [t] + Fuel uplift for the flight [t] - Amount of fuel contained in tanks at block-on at the end of the flight [t]
The moment of block-on may be considered equivalent to the moment of engine shut down. Where an aircraft does not perform a flight previous to the flight for which fuel consumption is being monitored, the aircraft operator may substitute the quantity ‘Amount of fuel remaining in aircraft tanks at block-on at the end of the previous flight’ with the ‘Amount of fuel remaining in aircraft tanks at the end of the previous activity of the aircraft’, as recorded by technical logs.
