To answer Deputy Stanley's question, one of the evidence points we heard was from the Department of Transport, Tourism and Sport. It did not have any plan or clear pathway over the next ten years for closing the 100 million tonne gap that we have. However, the one initiative that the Department did cite was a reduction in the motorway speed limit by 10 km/h, to 110 km/h for cars and 80 km/h for HGVs, which it estimates would save 2 million tonnes. That is not a small amount and the initiative might also improve safety too. It is a very practical measure. We have to figure out where we are going to get the 100 million tonnes in savings. It is all about the carbon and the speed limit reduction would yield a 2 million tonne saving.
