Carbon dioxide equivalent (CO2eq)
A universal unit of measurement used to indicate the global
warming potential of a greenhouse gas, expressed in terms of the global warming potential of one
unit of carbon dioxide. It is used to evaluate the releasing (or avoiding releasing) of different greenhouse gases against a common basis.

EU ETS
European Union Emissions Trading System. This is a Europe wide scheme which puts a
price on carbon that businesses use and creates a market for carbon. It has been in place
since 2005.
Intergovernmental Panel on Climate Change (IPCC)

Kyoto gases
These are the gases covered by the Kyoto Protocol: Carbon dioxide (CO2), methane
(CH4), nitrous oxide (N2O), hydroflurocarbons (HFCs), perflurocarbons (PFCs), and sulphur
hexafluoride (SF6).
Kyoto Protocol
A protocol to the United Nations Framework Convention on Climate Change
(UNFCCC or FCCC). The Kyoto Protocol establishes legally binding commitments for the reduction
of the Kyoto gases which came into force in 2005 and committed signatories to a reduction in
greenhouse gas (GHG) emissions.
PAS 2050
BSI Standard Assessing the life cycle greenhouse gas emissions of goods and services by DEFRA.
Scope
GHG Protocol definition which defines the operational boundaries in relation to indirect
and direct GHG emissions.
Scope 1
Emissions from sources that are owned or controlled by the reporting company. Also
known as direct emissions.
Scope 2
Emissions that are a consequence of the operations of the reporting company, but occur
from sources owned or controlled by another company, e.g., as a consequence of the import of
electricity, heat, cooling or steam. Also known as indirect emissions or energy indirect emissions.
Scope 3
Emissions that are a consequence of all other activities which release emissions into the
atmosphere as a consequence of your actions, which occur at sources which you do not own or
control and which are not classed as scope 2 emissions. Also known as other indirect emissions.
Stern Review
“Stern Review on the Economics of Climate Change” released on 30 October
2006. Sir Nick Stern was asked to lead a major review of the economics of climate change, to
understand more comprehensively the nature of the economic challenges and how they can be
met, in the UK and globally.
UNEP
