Concepts and definitions

Charcoal

Charcoal is a solid fossil fuel with an effective thermal value of more than 24MJ/kg in ashless substance. Coal is mainly graded according to the amount of volatile matter it contains and its thermal value.

Metallurgical coal and coke produced from it are not regarded as charcoal.

Derived gases

Manufactured gases excl. biogas

Energy incorporated in products for non-energy use

Energy incorporated in products for non-energy use.

Energy losses

Energy losses all kinds of (during extraction, distribution, storage and transformation, and dissipative heat from end use).

Fossil fuels

Fossil fuels refer to fuels that have been formed of biomass and stored underground millions of years ago. Fossil fuels include coal, lignite, natural gas and fuel oils refined from crude oil. In international classifications peat is often classified as fossil fuel, although it is a clearly younger fuel than them.

Natural energy inputs

Energy inputs originating from nature.

Non-renewable waste

Non-renewable waste.

Peat

Comprises following fuel classification categories:

• Milled peat (2110)
• Sod peat (2120)
• Peat pellets and briquettes (2130).

Renewable waste

Renewable waste.

Resident principle, national territory principle and bridging items

The statistics on emissions into air by industry, which are accordant with the regulation on environmental accounting, also contain Finnish citizens' emissions from land, water and air transport and from Finnish fishing vessels operating abroad. The emissions by foreign citizens from land, water and air transport on Finnish territory are subtracted from the emissions into air by industry.

This resident principle approach is different from that used in the greenhouse gas inventory, which only contains the emissions generated in the territory of Finland regardless of the nationality of the individual causing the emission (national territory principle). The difference between the greenhouse gas inventory and the statistics on emissions into air by industry is recorded in the bridging table for each emission component.

The bridging table contains data on Finnish citizens' emissions from land, water and air transport and from Finnish fishing vessels operating abroad, and on emissions by foreign citizens from land, water and air transport in Finland.

Wood fuels

Comprises following fuel classification categories:

• Firewood (stems and split firewood) (3111)
• Chips from roundwood (3112)
• Forest residue chips (3113)
• Bark (3121)
• Sawdust, cutter shavings etc. (3122)
• Wood residue chips (3123)
• Unspecified industrial wood residue (3128)
• Other industrial wood residue (3129)
• Black liquor and other concentrated liquors (3130)
• Other by-products from wood processing industry (3140)
• Recovered wood (3150)
• Wood pellets and briquettes (3160).
