The COP21 Agreement among the governments of the world obliges them to initiate the process of halting or reducing the emission of greenhouse gases, especially CO₂:s by 2018-2020. In the social sciences, the commitment calls for decentralised policy-making by the states or nations. The technical term is policy implementation. But the lessons from the policy sciences is that implementation, viz successful implementation is hard to come by. Avoiding lengthy and transaction costly discussions about economic policy measures, the article suggests a simple administrative solution: Dismantle coal fired power stations as much as possible; put strong filters on the remaining ones until they can be abandoned; compensate the biggest emitters of CO₂ from the new super fund. Awaiting the massive transfer from fossil fuels to renewables will be too slow process for stemming climate change, however desirable this is.
