TUC demands more support for manufacturing

Personally I think I'd only favour state aid to manufacturing reneable-related technologies. It's the only way to go for the blunt instrument of state-aid. But actually there are probably other and better ways to help British manufacturing, carbon tax or something similar would be better since it would mean that transporting atoms half-way round the world becomes more expensive [thus reflecting better its true cost; taking externalities of environment, social cost and resource depletion into account]. Its't it about time 'joined up government' included joined up to the environment?
