Current instrumentation is partial and is internally inconsistent, with mutually conflicting instruments. Most basically, current instrumentation lacks a clear long term strategy based on design thinking. However, the 2-degrees climate goal, with around 90% CO2 emission reduction for the EU by 2050, can be achieved with different sets of instruments. The report takes a long term view regarding Instrumentation strategies and instrument mixes for the EU’s climate policy. It develops two sets of instruments that are internally consistent and mostly mutually exclusive, based on two main strategies: a planning & control strategy and an institutionalist strategy.
