An earlier version of this article was written but unpublished back in 2008 and it has now been revised and published to take account of various changes since then.

The case is made for the provision of free public transport in every major town and city worldwide for a multitude of reasons. It has always been a good idea and should have been done a long time ago, but now with three major issues of our time; resource depletion, including oil, pollution and the climate crisis; they make it imperative that we move to such a system, both to conserve dwindling supplies of cheap energy, to reduce the use of vast mineral resources to make hundreds of millions of cars and to dramatically reduce our carbon emissions because climate change is happening faster than expected.

The Earth's climate has turned out to be more sensitive and complex than anticipated as evidenced by the recent dramatic record breaking summer ice melts in the Arcticc¹ in 2007, 2008, 2012 and basically every year since then. With such a large change in the albedo or reflectivity over a huge area of the Arctic, this signifies the jump into positive feedback of the climate system, although it is not the only positive feedback. Combined with preliminary reports that frozen methane is beginning to be released from the Arctic sea floor and tundra and given that methane is 20 times more powerful as a greenhouse gas, it is clear we are probably at the point of things running out of control. Emissions need to be cut drastically, starting about 20 years ago.

Moving to free and well-designed public transport allows society to deal with these problems in the least disruptive manner and to do so in the most equitable way and it would increase the shared sense of everyone working together to cope with what are essentially going to be permanent problems. Free public transport is not the full solution but is definitely an important first step. Switching to public transport has the potential to achieve large scale reductions in fuel use and it can be done immediately without further research or perfection of any technology. The current status quo plan to replace all the petrol and diesel fuelled cars with electric ones still leaves us with the problem of massive resource usage, a replacement of oil wars for lithium wars, traffic congestion, deaths from air pollution , high accident rates and actually high energy use. It does not matter if the heavily promoted so called solution of producing millions of electric cars is run on renewable energy because it would require vastly more wind farms, solar farms and whatever else compared to a transport solution based on highly efficient, globally deployed free public transport system which would only require a fraction of energy and resources of a car based one.
