The so-called Third World must now start developing implementation strategies of the COP21 objectives. In both emerging economies and poor countries, CO2:s area rather high except some countries where CO2:s are very high. Thus, the energy reliance upon coal – wood or solid – as well as petroleum must be transformed somehow. Hydro power requires lots of water, which further global warming may deny – look at Venezuela today. Thus, major investments in wind, solar or/and nuclear power are called for, which will have to be partly financed by the COP21 superfund. Yet, implementing a major decarbonisation conflicts with the developmental goals of Third World countries whatever they may be: “catch-up”, reducing poverty, UN development framework, etc. Implementation theory (Wildavsky, Sabatier) teaches us humbleness about the likelihood of goal fulfillment.
