<div>The level of efficiency of technologies is a measure that can be implemented on corporate level. In the transportation sector that could for example lead to maximum levels of greenhouse gas emissions of vehicles. Car manufacturers are well organized and heavily represented with policy makers. This makes it relatively easy to come to agreements on how to organize these measures. Another example is energy efficiency of appliances. There are a few very large manufacturers of household appliances in Europe. If it becomes mandatory for these manufacturers to reduce the energy consumption of their appliances, big steps can be made.<br></div>
