I think you start your argument from the point, that sustainable energy is around the corner. I have to point out, a lot of people have thought that way for a long time. The instantaneous effect is very important if there isnt sustainable energy around the corner. If it isnt, this is plain and simply an extremely inefficient way to produce plastics. Creating plastics from non petroleum sources is of course a great process, but it wasnt developed by Lego. Others arent using it because they produce actually a bigger footrpint with this "sustainable" process". If I dont miss anything, Lego adapted to that process before there was a positive impact or even before a non negative impact is a realistic prediction.
