Deleting emission allowances and credits

This page is being updated in relation to new regulations. Please refer to the executive order regarding the Emission Trading Registry. One way to help improve the global climate is by deleting emission allowances and credits.

Account holders in the EU ETS Registry and the Danish Emission Trading Registry can choose to delete, i.e. eliminate, a number of their emission allowances and credits. The deletion of one emission allowance or credit removes the permission to emit one tonne of a greenhouse gas. This means that countries or companies which could otherwise use this allowance or credit are compelled to reduce their greenhouse gas emissions by one tonne.

Even if an emission allowance or credit is deleted in the Danish section of the EU ETS Registry or in the Danish Emission Trading Registry, one cannot be certain whether the resulting reduction of greenhouse gases takes place in Denmark or in another member state. Reductions in other countries also help the global climate, however.

Account holders may request the deletion of emission allowances or credits by writing an e-mail to the Danish Business Authority at

“Carbon-neutral” products or services

Companies wishing to offer “carbon-neutral” products or services typically do this by buying emission allowances or credits equivalent to their greenhouse-gas emissions and then deleting them. In so doing, they ensure that their greenhouse-gas emissions are offset by a similar emission reduction somewhere else.

This is also an option for private individuals who wish to do the same thing, but private individuals are required to have an account in the EU ETS Registry or the Danish Emission Trading Registry in order to buy and delete emission allowances and credits. However, there are undertakings and environmental organizations which offer to do this on behalf of others. To make sure that the specified number of emission allowances or credits are deleted on your behalf, you must ask the undertaking or organization to present documentation proving that the deletion took place.
