A Europe-wide survey has exposed how cultural heritage institutions (CHIs) protect humanity's legacy digitally while unintentionally harming the environment.

Instead of focusing only on efficiency, the Europeana Climate Action Community recommends a shift towards environmentally sustainable and regenerative digital preservation.

Led by the Environmental Sustainability Practice Task Force, the survey collected input from 108 organisations across 24 EU countries. While 80% of CHIs recognise environmental responsibility, just 42% follow formal environmental strategies and a mere 14% measure carbon footprints.

Many maintain redundant data backups without assessing the ecological cost, and most lack policies for retiring digital assets responsibly.

The report suggests CHIs develop community-powered archives, adopt hardware recycling and repair, and prioritise sufficiency instead of maximising digital volume. Interviews with institutions such as the National Library of Finland and the POLIN Museum revealed good practices alongside common challenges.

With digital preservation increasingly essential, the Europeana Initiative calls for immediate action. By moving from isolated efficiency efforts to collective regeneration strategies, CHIs can protect cultural memory while reducing environmental impact for future generations.
