Committee on Climate Change (CCC)
The CCC is an independent body established under the Climate Change Act to advise the UK Government and devolved administrations on reducing greenhouse gas emissions.
United Nations Framework Convention on Climate Change (UNFCCC)
The United Nations Framework Convention on Climate Change (UNFCCC) is an international environmental treaty. The objective of the treaty is to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
The treaty itself set no binding limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms. In that sense, the treaty is considered legally non-binding. Instead, the treaty provides a framework for negotiating specific international treaties (called "protocols") that may set binding limits on greenhouse gases.
Intergovernmental Panel on Climate Change
The Intergovernmental Panel on Climate Change (IPCC) assesses the scientific, technical and socio-economic information relevant for the understanding of the risk of human-induced climate change. They provide advice to the UNFCCC on the scientific evidence and developments which are used to inform National Inventories.
Meteorological Office (Met Office)

GLOSSARY
Adjusted emissions
Greenhouse gas emissions that have taken into account purchases/sales through the EU ETS. Adjusted emissions may be higher or lower than actual emitted emissions depending on the quantity of purchases or sales. Scottish Government emission reduction targets are assessed using adjusted emissions.
Afforestation
The act or process of establishing a forest on land that has not been forested in recent history.
Baseline Period
Emissions reduction is based on a Baseline Period. For the greenhouse gases CO2, CH4 and N2O, 1990 was specified as the baseline. 1995 is the baseline for emissions of the F-gases.
Carbon dioxide (CO2)
Carbon dioxide is one of the main gases responsible for climate change. It is mostly emitted through the oxidation of carbon in fossil fuels, e.g. burning coal.
Carbon sink
A carbon sink is a natural or artificial reservoir that accumulates and stores CO2 for an indefinite period.
Climate change
Climate change is a long-term change in the earth's climate. This can be accelerated by human activity, e.g. by releasing CO2 into the atmosphere.
Deforestation
The removal of forest stands by cutting and burning to provide land for agricultural purposes, residential or industrial building sites, roads, etc., or the harvesting of trees for building materials or fuel.
EU ETS
The European Union Greenhouse Gas Emissions Trading System (EU ETS) is the largest multi-national emissions trading system in the world. Launched in 2005, the EU ETS is an EU policy aimed at mitigating climate change by limiting greenhouse gas emissions from industry sectors and aviation. Operating across Europe the system is mandatory for large energy-intensive industrial installations. Compared with 2005 levels, the EU ETS aims to deliver a 21 per cent reduction in emissions by 2020 and a 43 per cent reduction by 2030. Participants include more than 11,000 heavy energy-using installations in power generation, the manufacturing industry and airlines across 31 countries in the European Economic Area (EEA).
Over 11,000 installations throughout the EU are covered by the system, accounting for nearly 50 per cent of the EU's total CO2 emissions.
The EU ETS began in 2005. Phase III started in January 2013 and runs to December 2020.
Fluorinated gases (F-gases)
F-gases are the generic name given to HFCs, PFCs, SF6 and NF3. These have been used as replacements for CFCs, which are ozone depleting substances that have been banned under the Montreal Protocol. They have very high global warming potentials.
Greenhouse effect
The greenhouse effect is the process by which heat from the sun is trapped within the Earth's atmosphere by greenhouse gases. This process is also known as radiative forcing.
Greenhouse gas
A greenhouse gas is a gas which absorbs infrared radiation emitted from the surface of the Earth, helping to retain a portion of that energy in the atmosphere as heat.
Global warming potential (GWP)
GWP is a measure of how much a greenhouse gas is estimated to contribute to global warming. It is a relative scale which compares the potency of each gas to CO2.
Hydrofluorocarbons (HFCs)
HFCs are produced commercially as a substitute for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). HFCs are largely used in refrigeration and insulating foam. Their Global Warming Potentials range from 12 to 14,800 times that of CO2, depending on the gas type.
Inventory
The inventory contains greenhouse gas emissions estimates for Scotland and the UK. The Inventory is a disaggregation of the UK Inventory, which is based on five major sectors: energy, industrial processes, agriculture, land-use, land-use change and forestry, and waste.
IPCCC
The Intergovernmental Panel on Climate Change (IPCC) assesses the scientific, technical and socio-economic information relevant for the understanding of the risk of human-induced climate change. They provide advice to the UNFCCC on the scientific evidence and developments which are used to inform National Inventories.
LULUCF
Estimates of emissions and removals from land use, land use change and forestry (LULUCF) depend critically on assumptions made on the rate of loss or gain of carbon in Scotland's carbon rich soils. In Scotland, LULUCF activities, taken as a whole, acts as a sink, absorbing more greenhouse gas emissions than it releases.
Methane (CH4)
Methane is a greenhouse gas that is around 25 times more potent in the atmosphere than CO2 over a 100-year time horizon. Main sources include agriculture and landfill.
National Communication (NC) Sectors
The UK NC sectors are agreed groupings of the more detailed sectors reported to the United Nations Framework Convention on Climate Change by the UK. This report uses Scottish Government sectors. Mapping of these to NC sectors and IPCC sectors can be seen in Section E.
Nitrogen trifluoride (NF3)
Nitrogen trifluoride is a greenhouse gas that is around 17,200 times more potent in the atmosphere than CO2 over a 100-year time horizon. The main source of nitrogen trifluoride is in the making of semiconductors.
Nitrous oxide (N2O)
Nitrous oxide is a greenhouse gas that is around 298 times more potent in the atmosphere than CO2 over a 100-year time horizon. The main source is agricultural soil.
Other Petroleum Gas (OPG)
This consists mainly of ethane plus some other hydrocarbons, excluding butane and propane.
Perfluorocarbons (PFCs)
PFCs are a by-product of aluminium smelting. They are also the replacement for CFCs in manufacturing semiconductors. The Global Warming Potentials of PFCs ranges from 7,390 - 17,340 times that of CO2 over a 100-year time horizon.
Radiative forcing
An externally imposed perturbation in the radiative energy budget of the Earth's atmosphere. Such a perturbation can be brought about by changes in the concentrations of radiatively active species (e.g. greenhouse gases), changes in the solar irradiance incident upon the planet, or other changes that affect the radiative energy absorbed by the surface (e.g. changes in surface reflection properties).
Sequestration
The process by which carbon sinks remove carbon dioxide (CO2) from the atmosphere.
Source (UNFCCC definition)
Any process or activity which releases a greenhouse gas or a precursor greenhouse gas to the atmosphere.
Sulphur hexafluoride (SF6)
It is largely used in heavy industry to insulate high-voltage equipment and to assist in the manufacturing of cable-cooling systems. Its global warming potential is 22,800 times that of CO2 over a 100-year time horizon.
UNFCCC
In 1992, the UNFCCC was adopted as the basis for a global response to climate change. The ultimate objective of the Convention is to stabilise greenhouse gas concentrations in the atmosphere at a level that will prevent dangerous human interference with the climate system.
