This is incorrect. A large nuclear power plant uses about 200000 cubic meters of concrete. Each m3 of concrete contributes about half a ton of CO2 emissions, so that’s a one time 0.1 MT of CO2 emissions. A coal power plant of similar size will emit more than 1 MT every - single - year. There is simply no comparison.
