They could have replaced coal with all the new renewable energy sources and thus reduce the CO2 output. But instead they somehow decided it was a good idea to shut down nuclear power plants before they shut down the last coal plant. Per TWh produced, coal kills more than the power produced by Chernobyl. Generation 4 reactors will very likely begin operation in the next 6-10 years. Just look at the integral molten salt reactor as an example.
