Statistical Terms Glossary

Expenditure on “end-of-pipe” technologies used to treat, handle or dispose of emissions and wastes from production. This type of spending is normally easily identified even within the context of ancillary activity because it is usually directed toward an “add on” facility which removes, transforms or reduces emissions and discharges at the end of the production process.

Refers to the total number of patients alive on December 31st of each year who are receiving different forms of renal replacement therapy: haemodialysis/haemoinfiltration, intermittent peritoneal dialysis, continuous ambulatory peritoneal dialysis (CAPD), continuous cyclical peritoneal dialysis (CCPD), or with a functioning transplant.

Endangered species are taxa in danger of extinction and whose survival is unlikely if causal factors continue operating.
Included are taxa whose numbers have been drastically reduced to a critical level or whose habitats have been so drastically impaired that they are deemed to be in immediate danger of extinction. Also included are those that possibly are already extinct, in so far as they definitely have not been seen in the wild in the past 50 years

The Endangered Species Act (ESA) is a statute enacted in the United States in 1973 to conserve species and ecosystems. Under its auspices, species facing possible extinction are listed as “threatened” or “endangered,” or as “candidate” species for such listings. When such a listing is made, recovery and conservation plans are drawn up to ensure the protection of the species and its habitat.

An end-of-period exchange rate is the exchange rate ruling on the final working day of a given period

End-of—pipe protection refers to added technical installations for environmental control of emissions. They operate independently from the production process or are an identifiable part added on to production facilities

Fish/crustacean growth dependent upon the endogenous production of natural food organisms within the culture system through the use of fertilizers and manures as a source of nutrients (e.g., modified extensive pond farming systems).

It refers to what the crop is used for.

A sequence of processes/functions used to provide a specific service.

Hybrid accounts that show the supply and use of energy, by type of energy, and categories of supply and use.

Are accounting tables that provide information on the material input into an economy delivered by the natural environment, the transformation and use of that input in economic processes (extraction, conversion, manufacturing, consumption) and its return to the natural environment as residuals (wastes).

An energy budget is a record of the flow of energy through a system

Energy comparison labels indicate the energy efficiency of a particular model relative to similar models on the market, and are usually, though not always, mandatory.

Final energy consumed for movement of products by oil pipeline.

Quantities of fuel consumed by international and domestic aviation for propulsion, power and heating.
-        For international aviation (when the departure and arrival airports are in different national territories): quantities of fuels consumed by civil aircraft of any nationality during international flights transporting goods or passengers;
-        For domestic aviation (when the departure and landing airports are on national territory): quantities of fuels consumed by civil aircraft undertaking domestic flights transporting passengers or goods, or for purposes such as crop-spraying and the bench-testing of aeroengines.
Excluded are aviation fuels used by the military; and the fuels used by airport authorities for ground transport within the airport.

Quantities of fuel consumed by vessels transporting goods or people in domestic voyages (between ports of departure and destination in the same national territory without foreign intermediate ports of call).
Note: this may include journeys of considerable length between two ports in a country (e.g. San Francisco to Honolulu in the United States of America).

Final energy consumption by inland waterways transport (IWT) vessels.

Quantities of fuel consumed by ships of any nationality transporting goods or passengers during international voyages (when the ports of departure and arrival are in different national territories). Fuel consumed by ships during domestic transportation and fishing are not included.
Note: For the purpose of energy statistics, international marine bunkers are not included in exports; they are recorded separately due to their importance, e.g. for the estimation of greenhouse gas emissions.

Final energy consumption by merchant ships.

Quantities of fuel and electricity used in the support and operation of pipelines transporting gases, liquids, slurries and other commodities between points within the national territory. It comprises the consumption at pumping stations and for the maintenance of the pipeline. Consumption for maintaining the flow in gathering and distribution pipelines is excluded.

Energy consumed in rail traffic, including industrial railways and electrified urban rail transport systems. It includes tram, metro, subway, urban and suburban rail, high-speed train, and maglev. It excludes inputs into electrical power stations managed by the railways.
Note: Tram, metro and subway consumption is included here but not in rail statistics.

Quantities of fuel consumed by road vehicles for propulsion, whether utility vehicles or motor cars for own use or the use of others, including omnibuses belonging to railway companies.
It includes fuel used by:
- Agricultural vehicles on highways;
- Civil engineering vehicles licensed to use the public road network under road transport, in so far as they are subject to the normal taxation system;
- Trolleybuses, trolley trucks and other road vehicles with overhead wires.
It excludes energy used in stationary engines, for non-highway use in tractors (motor fuel consumed by agricultural vehicles), bitumen used in road surfacing and energy used in engines at construction sites.

Final energy consumption by ships.

Energy conversion factors are specific coefficients used to determine equivalence between units of mass and volume, energy and work and power; conversion factors are also used to convert quantities of energy production and consumption from their original physical units into a common unit of measurement
