Mr. Ross O'Colmain:

This goes back to market demand. If there is strong market demand for products that have low carbon in them, whether it is cement or alternative materials, it will drive innovation into low carbon products. That is something that we are seeing and we are supporting our companies to evolve to meet that market demand. It is beyond me to comment on how that demand is created but companies will respond to market opportunities and we are happy to support them doing that.
