A planning approval for a data centre in Mayo, Ireland, has been overturned following environmental concerns. The project, described as "environmentally toxic," had faced opposition from author Sally Rooney. The decision marks a reversal of earlier approval, highlighting growing scrutiny over industrial developments in the region.

The data centre, which had drawn criticism for its potential impact on local ecosystems, was initially granted planning permission. However, new assessments raised significant environmental issues, prompting authorities to revoke the approval. The move underscores the increasing influence of public and cultural figures in shaping local policy decisions.

Sally Rooney, known for her literary works, had publicly opposed the project, citing environmental risks. Her stance aligned with broader community concerns about industrial expansion. The reversal reflects a shift in regulatory priorities, emphasizing sustainability over economic development in sensitive areas.

The case has sparked discussions about the balance between technological growth and environmental protection. Authorities are now reviewing alternative proposals that may better align with ecological standards. The outcome may influence future projects in the region, setting a precedent for more rigorous environmental assessments.
