The City of Copenhagen has developed a strategic document "Sustainability in Construction an Civil Works" (2016), to ensure that the substantial investments by the City of Copenhagen in construction and civil works are managed in an environmentally responsible way. The City has therefore chosen to take the lead with environmental requirements that go beyond the existing laws. These requirements apply only to construction and civil works commissioned or supported by the City and include, for example that:

- On all city projects, all materials suitable for recycling must be source-separated and cleaned. In construction or civil works that involve demolition and/or renovation, all materials suitable for recycling should be sorted at source and cleaned. This will ensure that the materials can be reused or recycled and not sent to landfill.

- Uncontaminated construction rock material must be crushed and reused on site, unless the Municipal Environmental Protection Department determines that this is not acceptable for the local environment.
