Twenty-five products and services have been selected for the Green Directory at Automechanika in Frankfurt. Dr. Gerhard Angerer of the Fraunhofer Institute for System and Innovation Research (ISI) has evaluated the 73 products and services submitted by 55 companies in accordance with their innovativeness and environmental friendliness. The criteria were: contribution to climate protection, a more efficient use of energy, the reduction of acoustic or particulate emissions and/or the efficient use of resources and materials. The Green Directory guides visitors to selected, environmentally-friendly, low-emission technologies, products and services from seven categories. Thus, the Green Directory reinforces the main theme of the 20th Automechanika, which focuses on global warming and its impact on the automotive aftermarket.
