Challenge 1 -‐ a 20% reduc*on of CO2 emissions and 14% renewable energy genera*on in 2020. An enormous challenge Challenge 2 -‐ more commercial ini*a*ves, a reduc*on of government and reduc*on of governmental spending. How to combine these two challenges? The ingredients are: leave more to the market, coopera*on between companies & knowledge ins*tutes and a green deal with partners.
