As the process of global warming pushes ahead, the UNFCCC keeps holding its large scale reunions, producing declarations only. Economists call these meetings transaction costs, because most of the CO₂ emissions are produced by a small set of huge countries that could take speedy counter-action, if they wanted so. However, the COP21 Agreement about decarbonisation in this century is far too optimistic and does not confront the major obstacles in state coordination and international governance. One may devise utopian solutions to the global warming problematic, which is basically an energy problem, speaking of sustainable development. But realities are different, as the countries of the world cannot afford refraining from the fossil fuels. Energy innovations are available, but only on a small scale. Global warming results from the gigantic employment of energy resources, i.e. fossil fuels and wood coal. They are deemed necessary for economic and social development. The management tasks behind the COP21 project are simply too daunting, both nationally and internationally.
