The Danish Emission Trading Registry handles allowances and credits. The Danish Emission Trading Registry makes it possible to promote Danish reductions of CO2 cost-effectively.
The European trading system for CO2 allowances took effect from 1 January 2005. In October 2008 the system was coupled to the UN. Today these make up a worldwide system for trading allowances and credits.
Trading is registered via a network of electronic emission registries within which each EU country has its own registry.
A CO2 allowance is an electronic unit with a unique number which entitles the owner to emit one tonne of CO2 for a specific period.
A CO2 allowance can be used in all EU countries, no matter where in Europe it was issued.
Credits are earned through investments in approved climate projects over the whole world. A project must reduce emissions of greenhouse gases or increase CO2 removal by sinks. The CO2 benefit is translated into credits.
