Developing countries without emission reduction commitments, as defined in the Kyoto Protocol
Units ascribed to the reduction of greenhouse gas related emissions
Market for emission reductions purchased by organisations wishing to offset their carbon footprint on a voluntary basis.
VER – Verified Emission Reduction
Emission reductions created by projects which have been verified outside of the Kyoto Protocol – including credits from pre-registration CDM projects; 1 VER corresponds to 1 tonne of CO2e emission reductions.
Market for emission reductions purchased by organisations with Kyoto targets.
Clean Development Mechanism – The provision of the Kyoto Protocol that governs project-level carbon credit transactions between developed (Annex 1) and developing (non-Annex 1) countries
Certified Emission Reduction – Carbon credits created by Clean Development Mechanism projects; 1 CER corresponds to 1 tonne of CO2e emission reductions
Joint Implementation - The provision of the Kyoto Protocol that governs project-level emission reduction transactions between between entities located in Annex 1 countries
Emission Reduction Units - The output of Joint Implementation projects. 1 ERU corresponds to 1 tonne of CO2e emission reductions
European Union Emissions Trading Scheme – A market-based ‘cap and trade’ system for GHGs adopted by European Union member states in January 2005 in advance of their obligations under the Kyoto Protocol
European Allowance – Allowance unit issued to installations covered by the EU ETS.
Carbon dioxide equivalent – The unit used in the Kyoto Protocol
