The thing about fossil fuels—which is at the core of this bill, in terms of reducing the costs for road-user charges—is that they are formed from literal fossils of plants and animals that lived millions of years ago. Despite decades of commercial and political obfuscation and delay, we have known relatively clearly since the 1960s that, without a shadow of a doubt, burning those fossil fuels contributes to the warming of our atmosphere. We also had an Intergovernmental Panel on Climate Change report that came out only this past weekend, which demonstrated that we must think ahead and act now. We must make sure that we are not creating perverse incentives and feedback loops, such as the Greens are stating are at serious risk of occurring with the passage of this legislation, when alternatives are available.
