Deleting emission allowances and credits

One way to help improve the global climate is by deleting emission allowances and credits.

  • Updated 1. December 2023

Account holders in the Danish EU ETS Registry and the Danish Kyoto 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 ton 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 ton.

The Danish Business Authority can issue a certificate of deletion of untis.
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 and private individuals 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.

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 should ask the undertaking or organization to present documentation proving that the deletion took place.
