Europe has ambitious laws and policies to protect air and water, to promote the circular economy, prevent waste generation, raise recycling rates, and safeguard nature. Implementation is key to achieving environmental objectives, and meeting obligations as defined by the EU environmental legislation. In 2016, the Commission undertook to report regularly on the state of the implementation of EU environmental legislation. It launched the Environmental Implementation Review (EIR), a tool that helps Member States address systemic obstacles to environmental integration by identifying the causes behind poor implementation and by sharing good practices through peer-to-peer support. This factsheet summarises the progress achieved and the remaining challenges identified for Denmark in the third EIR package published in September 2022. Most of the country is cultivated and over 10% is covered by roads and built-up areas, with the main urbanisation around Copenhagen. Despite these challenges, environmental policy implementation in Denmark remains at a high standard however, Denmark still needs to step up action on waste management and on agricultural pollution.
