Mr. Denis O'Sullivan:

CNG and LNG are very different. In the case of CNG, one is taking gas from the network and compressing it in order that it will fit into a storage vessel that can be attached to a truck similar to its diesel tank. The benefits of CNG are quite obvious. In deploying it we do not need capital or any other support because we can do it on a commercial basis and it will immediately deliver a 20% reduction in emissions. As important, it provides a pathway to the use of renewable gas in transport. The argument on the use of CNG is extremely clear.
