The Swan logo demonstrates that a product is a good environmental choice. Criteria include environmental, quality and health arguments. The green symbol is available for more than 65 product groups for which it is felt that eco-labelling is needed and will be beneficial. These days, everything from washing-up liquid to furniture and hotels can carry the Swan label.
Criteria are revised on an average of every 3 to 4 years. Products must fulfil the new criteria and companies must re-apply for a license. In this way, it is ensured that products are constantly being improved. In the section of furniture there is also a category for lightling.
