So there is a cost coming to ports, which are already capital constrained. As with so many other pieces of legislation which express good intentions, this piece of legislation actually will have an environmental benefit. They come at a cost. While we must accept that there are trade-offs between environmental benefits and costs, and that sometimes Government regulation is required so that business actually internalises the environmental effects as a cost, rather than externalises those costs to the environment. So there is a place for Government regulation where there are no other incentives that will work effectively. But at the same time that these costs are being imposed, businesses are expected to face a raft of other costs, whether they be extra public holidays that the business sector did not ask for but are expect to pay for, whether they are extra taxes and duties and levies, such as fuel excise duty.
