The Blue Angel is the ecolabel of the federal government of Germany since 1978. The Blue Angel sets high standards for environmentally friendly product design and has proven itself over the past 40 years as a reliable guide for a more sustainable consumption. Blue Angel The letters ‘CE’ appear on many products traded on the extended Single Market in the European Economic Area (EEA). They signify that products sold in the EEA have been assessed to meet high safety, health, and environmental protection requirements. When you buy a new phone, a teddy bear, or a TV within the EEA, you can find the CE mark on them. CE marking also supports fair competition by holding all companies accountable to the same rules. CE marking is a part of the EU’s harmonisation legislation, which is mainly managed by Directorate-General for Internal market, Industry, Entrepreneurship and SMEs. The CE marking for Restriction of Hazardous Substances is managed by Directorate-General for Environment. Comprehensive guidance on the implementation of EU product rules can be found in the so-called Blue Guide.
