DECOMMISSIONING: "Marine Biodiversity Impact Pathways for Offshore Wind Farm Decommissioning: Implications for Life Cycle Impact Assessment Development" - Standdorf et al., 2024
In light of the global expansion of offshore wind energy and the impending decommissioning phases of numerous wind farms, the question of how decommissioning processes can be designed in a biodiversity-conscious manner is becoming increasingly urgent. The article “Marine Biodiversity Impact Pathways for Offshore Wind Farm Decommissioning: Implications for Life Cycle Impact Assessment Development” by Stranddorf et al. (2024) offers a groundbreaking analysis by presenting, for the first time, a comprehensive impact pathway model that systematically structures and visualises the effects of decommissioning on marine biodiversity.
The authors identify and classify the complex ecological interactions triggered by decommissioning activities – such as physical habitat destruction, sediment resuspension, noise, pollutant release, or altered trophic dynamics. The study compellingly demonstrates that decommissioning goes far beyond purely technical procedures, intervening in profound biological processes whose long-term consequences remain poorly understood. Particularly noteworthy is the integrative research approach, which combines natural scientific, regulatory, and planning perspectives.
The article not only provides a robust foundation for further empirical research but also outlines key requirements for biodiversity-conscious decommissioning governance. These include transparent assessment frameworks, long-term monitoring programmes, and adaptive decision-making structures that actively take ecological uncertainties into account. With this contribution, Stranddorf et al. establish a crucial reference model for science, policy, and industry – one that charts a path toward a biodiversity-oriented transformation of the marine energy landscape in the 21st century.
