Climate Change Bill [HL]

I am completely ignorant, but I thought that that was how the City worked on all the commodities in the world. I thought that manufacturers who are making products with raw materials buy on the futures and that the price of their end products going out of the factory gates was fixed. I was the mere factotum at a factory making these things, which I did not own, yet the cost of the products and materials that we used went up and down every day on the world markets. Account is taken of that. I thought that that was what the City of London was for.
