Presentation in session 111 during the World Sustainable Building Conference 2014 in Barcelona (28-30th .Oct. 2014) The theme of the WSB14 was: "Sustainability. Are we moving as quickly as we should? It is up to us!" Session 111 (out of 144 sessions) had to answer the question: "Are we moving in the same direction?" This presentation on behalf of the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety, gives an overview of the policies and tools in place for declaring environmental performance on construction products and buildings. This presentation was one out of the 5 from this session 111. After a questioning, answering and discussion with the audience the session concluded: "No, we are not moving in the same direction!" see WSB14-Sessions 111-0 to 111-4
