If you want to use that measure, then everything has some emissions in its cycle including wind, solar etc. And per unit of energy generated, nuclear is still the lowest. The amount of energy going into a 1MW wind generator and the long power connection is huge, and with a 20-25% average generation, it takes many years or decades to pay off.
As for waste, with reprocessing, the volume of waste is reduced, and what is left has only a tiny fraction of the radioactivity of the original waste.
This has been done very effectively in France.
As for "renewable" power, there is no commercially viable base load supply yet.
Considering the growth in power demand, to even meet the 5% reduction target by 2020 will either require nuclear power or a technology we presently don't possess.
