PEF, CSR, LCA, Carbon Footprint, OLCA, Social LCA, and Eco-efficiency are only a subset of the many catch phrases and keywords corporations encounter when confronting “their” environmental impacts. ifeu knows all the methods and provides consulting and support for corporations on their journey towards ever increasing environmental consciousness. ifeu has been providing highly competent scientific consulting services on environmental matters for more than 35 years now. The primary focus of our fully independent consulting is on the subject area environment, which is essentially separate from any other service. The ifeu expertise balances expectations of environmental organisations, consumers, and politics with business management, economic and technological constraints. A suitable tool is the eco-efficiency analysis which we have used in various projects (such as in a project for Gerolsteiner Brunnen GmbH).
