Climate Change
I am writing this on the first day of the Copenhagen Conference on Climate Change. It may seem strange to some to have created a website commemorating maps issued by petrol companies that may have encouraged motorists to make unnecessary or even frivolous journeys. But it should be remembered that these maps are historical documents of their time and reflect the prevailing social and economic conditions. And the companies publishing them, by and large, were only trying to develop their business unaware of the environmental problems that might follow. This is not to deny the large contribution that motoring has made to emissions of carbon dioxide (CO2). Most of the oil burnt over the past century or so has been locked under the ground for tens of millions of years; combustion of this petroleum has led to CO2 levels higher than seen on earth for over 700,000 years. Given that CO2 is known to trap the sun's heat in the atmosphere, it should be no surprise that the consensus view is that man (and motorists in particular) have contributed to the small, yet significant rises in average global temperatures since 1900. If these rises are not to get out of control and lead to greater climate instability, including significant melting of arctic ice and associated sea level rises, then we will all have to cut down our energy use.
In particular, we need to review how we use and choose our cars; sometimes we may be able to avoid car journeys completely, for example by walking, cycling or using public transport. And those of us lucky enough to be able to select a new car can look closely at typical emissions - some models emit under 100g/km of CO2, but others use four times as much fuel (and four times the emissions). Of course, careful driving techniques and route selection may also help a little. This site has also reproduced tips for economical driving for many years, and a using a road map before setting out can help limit emissions.
Alternative fuels may not be the panacea that they were once thought to be. Hydrogen requires considerable energy in its production and is far from economically viable at present; LPG (or CNG) offers only limited savings compared to diesel (or even the latest petrol engines). Biofuels compete for land, often in the very countries where that same land is most needed for food, and diversion of US corn into bioethanol production has certainly led to significant food price rises in countries such as Mexico. Biodiesel can be damaging, especially if palm oil plantations are allowed to replace biodiverse rain forests in areas such as Southeast Asia.
Of course, biofuels are not a new idea. In the 1930s, a company was set up in Germany to manufacture ethanol for road use, principally from potatoes. And this website now shows a couple of maps that they produced...
Tim Nicholson, my good friend and fellow map collector, died in June 2009. Tim was an author and expert on early motor cars - especially those made by Riley - as well as the editor of many of the Readers Digest's guides to Britain, where he was able to put his deep knowledge of what makes a good map to practical use. As a collector, Tim had an extensive knowledge of maps of all types, especially British maps and those of the 100 years up to 1939 and had often been able to show me maps that I had not otherwise seen. Some of these maps are now able to be scanned and included on this site for the first time. However, Tim will be very much missed by all those who knew him.
