A minimum price for emission allowances offers the best opportunity for the EU Emissions Trading System (ETS) to function as a key policy instrument in reducing CO2 emissions.

When the price of CO2 is too low, it is often more efficient for companies to buy emission rights rather than to invest in emission reduction
