Prof. Ernst Ulrich von Weizsäcker is one of the gurus of resource efficiency present at the WRF 2011. I had the privilege to interview him. I asked about him how did we arrive to the present resource squandering and how should the political and economical frame change to establish a sustainable resources use?
How did the perception of resources changed during the last 40 years? Are politicians ready to change something? What should they change? Is the business sector moving towards resource efficiency? Are investors ready to pay for sustainable resources management?
Listen to the answers of Prof. Weizsäcker…
Prof. Weizsäcker is the right person to ask these questions, as he has deep knowledge about resources. He is co-chair of the International Resources Panel; member of the Club of Rome; was Dean of the Donald Bren School at the University of California; and founded the Wuppertal Institute. His engagement was widely recognized, as he won prizes as the Takeda Award and the German Environmental Prize.
The core ideas of Weizsäcker are published in his bestseller Factor Four of 1997. In the book he shows 50 examples proving how the wealth gained from the resources we use can be increased at least four times. In 2010 he published Factor Five. The book focuses on innovation in industry and technology, as well as policy, of the last 15 years.
Factor Five explores four sectors having large potential to improve material and energy productivity by 80% or more. The hyper car of Amory Lovins using 1.2 L fuel per 100 km improves fuel efficiency by a factor 10; passive houses, and the replacement of incandescent light bulbs with LED ones do as well.
