Baseline Emissions Inventory:

A Baseline Emission Inventory is a quantification of the amount of CO2 emitted due to energy consumption in the territory of a Covenant signatory during a baseline year. It allows to identify the principal sources of CO2 emissions and their respective reduction potentials.

Data commercial sensitivity:

Data whose disclosure could reasonably be expected to result in a material financial loss or gain to the person to whom the information relates, or could prejudice the competitive position of that person in the conduct of his or her profession or business or otherwise in his or her occupation.

Data management:

Data management activities consist in all activities performed during the following phases of data collection, data processing, data modelling and data dissemination. These data management activities are needed to help define, implement or monitor SEAP.

Data privacy and regulation:

All necessary precautions required by one of the parties to prevent the disclosure of information (such as confidentiality agreement, data protection for instance through encryption,etc.

Data quality analysis:

Energy data quality analysis and data communication to decision makers are crucial elements for the implementation and monitoring of effective SEAP actions. Energy data quality at a community level can be affected by many external factors (such as variations in population, economic growth, ..) leading potentially to a wrong analysis of the trends and determinants.

Energy data supplier:

An energy data provider or data source provides data to public authorities for energy planning. The energy data providers or data sources include: energy utility companies (Transport Systems Operators, Distribution Systems Operators, Energy retailers), Statistical offices, Housing associations, Industry associations, Air quality protection organizations, RES producers associations, etc.

Energy intensity:

Energy intensity measures the energy efficiency of an economy or sector of activity. It is calculated as the ratio of energy consumption to gross domestic product, or the value added of the sector of activity.

Final energy:

Final energy is the energy supplied to consumers, to be converted to useful energy. For example: electricity, petrol, gas, diesel fuel, domestic fuel, etc.

Monitoring Emissions Inventory:

Emission inventory that the local authority carries out to measure the progress towards target.

Normal weather

It is generally acknowledged that the consumption of heating is proportional to the severity of winter. The normal weather assessment corresponds to adjusted consumptions, taking into account the effects of temperature. Real weather consumptions are those which have actually been consumed over the year.

Primary energy:

Primary energy is the crude form of energy available in nature: wood, coal, natural gas, oil, wind,solar radiation, hydraulic power, geothermal energy… Primary energy is not always directly useable and is therefore often subject to conversions: for example, oil refining to obtain petrol or diesel fuel or combustion of coal to produce electricity in a thermal power plant.

Progress based indicators:

Progress based indicators allow the evaluation of the SEAP action (e.g: kms of biking ways, nb of public passengers per year).

Regional assessment of final energy consumption

The regional assessment of final energy consumption corresponds to the inventory of the use of different types of energy in regions. The measurements of the amounts of energy used express regional requirements in terms of travel, lighting, heating, the production of goods and services… The assessment of consumptions differentiates energies and sectors of consumption.

Regional energy and GHG emission observatory:

A regional energy and GHG emissions observatory is a structure or a dedicated organization within an existing structure collecting periodically data from energy data providers, processing these data and providing free energy and GHG emissions data to regional and local authorities or communities for sustainable energy planning. Usually this structure is:

  • Governed by a local consortium (including energy data providers and local public authorities)
  • Supported by public authorities and often integrated within existing regional organizations (such as energy agencies or public authority department)
  • Technical skills in data gathering, analysis and processing, partnership management, energy planning
  • Provide free of charge “community data” and data services to regional and local public authorities and communities.

These services include for instance:

  • Processing (aggregating or disaggregating) and modeling of raw data provided by data providers at national, regional and local levels
  • Identifying data sources and data communication tools for SEAP monitoring
  • Designing and implementing collaboration agreements with energy data providers that can benefit to a larger range of public authorities located within the same region (multiplier effect)
  • Providing periodic updates of energy and GHG emissions profiles for BEI/MEI estimates at regional or local community levels.

Regional Energy Planning Facilitator:

Whether they are regional energy agencies, Covenant of Mayors regional coordinators, regional statistical energy offices, department of a public authority in charge of data, or consultants in sustainable energy planning, the Regional Energy Planning Facilitators will play a pivotal role in facilitating and organizing the cooperation process between Energy data suppliers and Public Authorities. They will be able to implement data services and promote the setting up of supporting structures such as observatories.

Sustainable Energy Action Plan:

A Sustainable Energy Action Plan (SEAP) is the key document in which the Covenant signatory outlines how it intends to reach its CO2 reduction target by 2020. It defines the activities and measures set up to achieve the targets, together with time frames and assigned responsibilities. Covenant signatories are free to choose the format of their SEAP, as long as it is in line with the principles set out in the Covenant SEAP guidelines.


TCO2e: tonne of CO2 equivalent. Unit allowing equivalence to be provided between the various greenhouse gases nd carbon dioxide (CO2) in terms of the production of greenhouse effect.


Toe: The tonne oil equivalent (toe) is a unit for measuring energy commonly used by energy economists to compare energies. One toe is the energy produced by the combustion of an average tonne of oil, which represents approximately 11,600 kWh.


The prefixes represent multiples of units:

  • kilo (k, for a thousand,
  • mega (M, for a million),
  • giga (G, for a billion),
  • tera (T, for a trillion)

Useful energy:

Useful energy is the energy available to the consumer after it has been converted by his equipment (boilers, electric convectors, light bulbs). The difference between final energy and useful energy resides mainly in the efficiency of the appliances used to convert this final energy.
