Nuclear power has been kept outside of climate change mitigation mechanisms like CDM (Clean Development Mechanism) and JI (Joint Implementation) so far. However, some evidence shows that the nuclear lobby could be preparing its comeback at the next COP to have this dirty energy labeled as clean or carbon-free and thus benefit from new subsidies. Will our leaders let themselves be talked into financing a dangerous, costly and irrelevant technology, which would divert urgently needed money from real solutions to climate change?
