At the World Resources Forum (WRF) in Beijing, all environmental experts agree on the fact that today we need to take actions to tackle the problem of resources scarcity. Problematic, however, is to pinpoint who should lead the change. Prof. Munashinghe, the 2007 Nobel Peace Prize winner, gives a very pragmatic answer: “ Market share is the key element to understand where governmental policy should focus.” If the market has oligopolistic characteristics, policy actions should focus on the supply side. In an oligopsonic market, the opposite policy maker should take actions on the demand side to make the consumer aware about possible solutions path for the environmental issue. This solution is very important because it give a simple tool for policy maker to focus their strategy on the right market actors and therefore gain in efficiency.
