The environmental symbol is targeted at both consumers and companies. The Blue Angel supports the concerns of environmental and consumer protection. Accordingly, those products and services are labelled which are especially environmentally friendly based on a holistic appraisal. Since 2008 the "Blue Angel" has focused on climate-relevant products, but it also continues to be a means of identifying products which primarily protect resources, water or health. The environmental symbol was introduced in 1977 to identify energy-saving and environmentally-friendly products and it is similar to the European eco-label.
