Ecological offsetting

Through ecological offsetting, adverse impacts on biodiversity caused by human action in a certain area are offset by enhancing biodiversity in another area.

Ecological offsetting is a last resort means to be used when the harm cannot be prevented or mitigated. This means that it can only be used in cases where there is no other potential solution. Ecological offsetting contributes to the achievement of the target to halt biodiversity loss by 2030.

Voluntary ecological offsetting according to the Nature Conservation Act

Detailed provisions on the voluntary ecological offsetting procedure and offset criteria are laid down in the Nature Conservation Act.

The key principle of ecological offsetting is that a party causing deterioration, i.e. an operator causing deterioration of natural values in its activity, may offset the deterioration of a habitat type or the habitat of a species. Offsetting can take place either by generating natural values or through the avoided loss offset. The generation of nature values may involve improving the status of the site of a habitat type that has deteriorated by restoration, such as by restoring the hydrological balance of a mire or conserving a site with important natural values.

Decree on Voluntary Ecological Offsetting

Further provisions on voluntary ecological compensation are laid down in the Decree of the Ministry of the Environment that entered into force on 15 September 2023. They concern the measurement of deterioration and additionality, the measurement unit and calculation of the current value, and geographical boundaries and flexibilities related to offsetting.
