climate change mitigation-related support — support for activities in developing countries that contribute to the objective of stabilising greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system (22)

competent inventory authorities — authorities entrusted under a national inventory system with the task of compiling the greenhouse gas inventory (3)

ERU — a unit issued pursuant to the relevant provisions in the Annex to Decision 13/CMP.1 or in other relevant decisions of UNFCCC or Kyoto Protocol bodies (9)

ex ante assessment of policies and measures — an evaluation of the projected effects of a policy or measure (16)

indicator — a quantitative or qualitative factor or variable that contributes to better understanding progress in implementing policies and measures and greenhouse gas emission trends (6)

lCER — a unit issued pursuant to Article 12 of the Kyoto Protocol and requirements thereunder, as well as the relevant provisions in the Annex to Decision 13/CMP.1, or in other relevant decisions of UNFCCC or Kyoto Protocol bodies, that is to say credits given for long-term emission removals which are certified for an afforestation or reforestation CDM project, to be replaced upon expiry at end of the project’s crediting period or in event of storage reversal or non-submission of a certification report (12)

national inventory system — a system of institutional, legal and procedural arrangements established within a Member State for estimating anthropogenic emissions by sources and removals by sinks of greenhouse gases not controlled by the Montreal Protocol, and for reporting and archiving inventory information in accordance with Decision 19/CMP.1 or other relevant decisions of UNFCCC or Kyoto Protocol bodies (2)

national registry — a registry in the form of a standardised electronic database which includes data on the issue, holding, transfer, acquisition, cancellation, retirement, carry-over, replacement or change of expiry date, as relevant, of AAUs, RMUs, ERUs, CERs, tCERs and lCERs (13)

policies and measures — all instruments which aim to implement commitments under Article 4(2)(a) and (b) of the UNFCCC, which may include those that do not have the limitation and reduction of greenhouse gas emissions as a primary objective (14)

projections with additional measures — projections of anthropogenic greenhouse gas emissions by sources and removals by sinks that encompass the effects, in terms of greenhouse gas emissions reductions, of policies and measures which have been adopted and implemented to mitigate climate change as well as policies and measures which are planned for that purpose (20)

projections with measures — projections of anthropogenic greenhouse gas emissions by sources and removals by sinks that encompass the effects, in terms of greenhouse gas emissions reductions, of policies and measures that have been adopted and implemented (19)

projections without measures — projections of anthropogenic greenhouse gas emissions by sources and removals by sinks that exclude the effects of all policies and measures which are planned, adopted or implemented after the year chosen as the starting point for the relevant projection (18)

QA — a planned system of review procedures to ensure that data quality objectives are met and that the best possible estimates and information are reported to support the effectiveness of the quality control programme and to assist Member States (4)

QC — a system of routine technical activities to measure and control the quality of the information and estimates compiled with the purpose of ensuring data integrity, correctness and completeness, identifying and addressing errors and omissions, documenting and archiving data and other material used, and recording all QA activities (5)

RMU — a unit issued pursuant to the relevant provisions in the Annex to Decision 13/CMP.1 or in other relevant decisions of UNFCCC or Kyoto Protocol bodies (8)

sensitivity analysis — an investigation of a model algorithm or an assumption to quantify how sensitive or stable the model output data are in relation to variations in the input data or underlying assumptions. It is carried out by varying input values or model equations and by observing how the model output varies correspondingly (21)

system for policies and measures and projections — a system of institutional, legal and procedural arrangements established for reporting policies and measures and projections of anthropogenic emissions by sources and removals by sinks of greenhouse gases not controlled by the Montreal Protocol as required by Article 12 of this Regulation (15)

tCER — a unit issued pursuant to Article 12 of the Kyoto Protocol and requirements thereunder, as well as the relevant provisions in the Annex to Decision 13/CMP.1, or in other relevant decisions of UNFCCC or Kyoto Protocol bodies, that is to say credits given for emission removals which are certified for an afforestation or reforestation clean development mechanism (CDM) project, to be replaced upon expiry at end of the second commitment period (11)

technical corrections — adjustments to the national greenhouse gas inventory estimates made in the context of the review carried out pursuant to Article 19 when the submitted inventory data are incomplete or are prepared in a way that is not consistent with relevant international or Union rules or guidelines and that are intended to replace originally submitted estimates (24)
